5-Amino-1MQ5-Amino-1-methylquinolinium · NNMT inhibitorMitochondrial~4-6 hours (estimated)50-100 mg/day (oral)1× daily (oral)

NNMT inhibition in preclinical adipose models can change NAD+/SAM handling. That is not a proven basal-metabolic-rate doubling in humans.

α-Defensin 1 (HNP-1)Human Neutrophil Peptide 1 · HNP-1Antimicrobial~2-4 hours (estimated)Research onlyPer study protocol

Structured as a hyper-stable, cysteine-rich β-sheet, HNP-1 carries a massively positive charge. It aggressively targets the negatively charged outer membranes of invading bacteria, fungi, and specific enveloped viruses. Upon contact, it physically impales the pathogen's lipid bilayer, ripping open massive voltage-dependent ion pores resulting in immediate, unrecoverable osmotic lysis. Simultaneously, it actively hunts and recruits naive dendritic cells to process the destroyed pathogenic debris.

A9 compounds
Ac-SDKPN-acetyl-Ser-Asp-Lys-Pro · acetyl-SDKPImmuneMinutes-class (ACE-cleaved tetrapeptide)Research - no established human research-chem doseNot established

Negative regulator of pluripotent hematopoietic stem-cell proliferation in classical work; antifibrotic signaling appears in organ-fibrosis models. ACE inhibitors raise endogenous Ac-SDKP — that pharmacology is not a reason to inject a research vial as a fibrosis drug.

AdalankAdamantane-Selank · Adamantyl-SelankCognitiveUnknown (no published human PK)200-750 mcg/day (intranasal; vendor protocols only)1-2× daily (intranasal)

Adamantane is a lipophilicity/stability modification used on other peptides. That is a medicinal-chemistry rationale, not demonstrated Selank-receptor PK for this conjugate.

AdamaxAdamantane-Semax · Adamantyl-SemaxCognitiveUnknown (no published human PK)200-600 mcg/day (intranasal; vendor protocols only)1-2× daily (intranasal)

Adamantane is used on other peptides to increase lipophilicity and metabolic stability. That is a medicinal-chemistry rationale, not demonstrated Semax-receptor PK for this conjugate.

AdipotideCKGGRAKDC-GG-D(KLAKLAK)2 · Prohibitin-targeting peptideWeight Mgmt~2-4 hours (estimated)0.5-1 mg/kg (research)Per study protocol

Operating as a two-part molecular smart-bomb, Adipotide features a homing domain (CKGGRAKDC) that locks onto prohibitin - a protein expressed exclusively on the surface of blood vessels feeding white fat. Once attached, it deploys a second pro-apoptotic domain [D(KLAKLAK)2] which violently ruptures the mitochondrial membranes of the endothelial cells. This forces immediate cellular apoptosis, choking off the blood supply to the adipocytes and causing the fat tissue to literally starve, die, and be reabsorbed.

AHK-CuCopper tripeptide-3 · Ala-His-Lys-CuCosmetic~1–2 hours (estimated; topical/injectable cosmetic PK sparse)1-2 mg/day (injectable research) or topical 0.5–2%1× daily or 2–3× weekly (injectable); 1–2× daily topical

AHK-Cu is studied as a hair-follicle and extracellular-matrix signal in dermal models, overlapping GHK-Cu’s copper-delivery and collagen-related gene effects. It is not a substitute for minoxidil or a prescription hair drug.

AmycretinNovo amycretin · amycretin oralGLP-1Investigational (Novo dual amylin/GLP-1)Investigational - sponsor protocol onlyTrial schedules only (oral and injectable programs)

Co-agonism at amylin and GLP-1 receptors for satiety and gastric-emptying effects. Distinct INN from cagrilintide, semaglutide, and the CagriSema fixed combination.

AOD-9604Anti-Obesity Drug 9604Fat Loss~30 minutes (estimated)300-500 mcg/day1× daily (fasted)

C-terminal GH fragment analog studied for lipolytic signaling without the full GH endocrine package. Failed late-stage obesity work is part of the file. Not Egrifta VAT math.

ARA 290Cibinetide · EPO-derived peptideNeuroprotective~2 minutes1-4 mg SC1× daily or 3× weekly

Instead of binding the classical homodimeric EPO receptor, ARA-290 exclusively targets the heteromeric Innate Repair Receptor (IRR). Upon binding, it orchestrates a massive, localized anti-inflammatory response by ruthlessly suppressing macrophage activation and silencing pro-inflammatory cytokines. Simultaneously, it activates profound anti-apoptotic pathways within dying nerve cells, physically forcing the regeneration and regrowth of destroyed small-fiber nerve terminals.

ArgirelineAcetyl hexapeptide-3 · Acetyl hexapeptide-8Cosmetic~4 hours (topical)5-10% topical solution2× daily (topical)

Operating precisely at the dermal neuromuscular junction, Argireline acts as a direct structural decoy. It meticulously mimics the N-terminal end of the SNAP-25 protein, aggressively competing for space during the assembly of the SNARE protein complex (combining with syntaxin and VAMP). By destabilizing this complex, it violently restricts the docking of vesicles and throttles the release of acetylcholine, plunging the target muscle fibers into a state of smooth, prolonged relaxation.

B7 compounds
B7-33Relaxin-2 B-chain analog · single-chain relaxin analogRecoveryMinutes-class (relaxin-family analog; SKU PK unpublished)Research; no established consumer doseNot established

B7-33 retains RXFP1 signaling with a simpler chain than two-chain H2 relaxin. Preclinical anti-fibrotic and vascular work exists. Gray-market vials are not that program.

BonomarlotBonomarlot A-20 · Bone Marrow CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Carrying ultra-low molecular weight (<10 kDa) nucleoprotein fractions, Bonomarlot penetrates deep inside the marrow cavity to hijack the nuclei of failing hematopoietic stem cells (HSCs) and stromal support cells. Serving as a massive epigenetic catalyst, it violently un-silences dormant DNA, forcing the massive, relentless structural production of erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes (platelets), entirely rebuilding the body’s blood supply from the root.

BonothyrkBonothyrk A-21 · Parathyroid CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Bypassing systemic circulation, Bonothyrk’s precise peptide fractions enter the nuclei of the parathyroid chief cells. Serving as an absolute epigenetic governor, it forcefully recalibrates the silenced genes responsible for the synthesis and precise pulsatile secretion of Parathyroid Hormone (PTH). This flawless, youth-level PTH regulation orchestrates the perfect physiological balance of calcium and phosphorus absorption across the gut, kidneys, and bone matrices.

BPC-157Body Protection Compound-157 · PentadecapeptideRecoveryMinutes (IV PK)*200-800 mcg/day1-2× daily

Operates via a highly pleiotropic mechanism that upregulates the expression of the Early Growth Response 1 (EGR-1) gene and vascular endothelial growth factor (VEGF). This aggressively stimulates focal angiogenesis - the creation of new blood vessels in avascular tissues (like tendons). Concurrently, it stabilizes the nitric oxide (NO) system, modulates the FAK-paxillin pathway, and accelerates the migration of fibroblasts to wound sites.

BremelanotideVyleesi · PT-141Sexual Health~2.7 hours1.75 mg (FDA approved dose)As needed (≥45 min before activity, max 1×/24 hours, ≤8×/month)

Functioning as a targeted neurological switch, Bremelanotide bypasses peripheral vascular mechanics and strikes directly at the Melanocortin-4 Receptors (MC4R) embedded within the hypothalamus and limbic system. This activates deep, primal arousal pathways, converting psychological desire into physical response. However, it concurrently agonizes MC4R receptors located in the brainstem’s area postrema, routinely triggering distinct, transient nausea as a primary physiological side effect.

BromantaneLadasten · bromantanCognitiveHours-class oral; adipose depot prolongs presence (review-level PK)Russian product / study context - not a US NDAOral courses in Russian clinical tradition (not a US label)

Actoprotector-class dopaminergic activation with reported tyrosine-hydroxylase upregulation in the Russian pharmacology tradition; not classical amphetamine reuptake blockade.

BronchogenAla-Glu-Asp-Leu · AEDLBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Navigating directly to bronchial epithelial tissue, Bronchogen slips into cell nuclei to operate as a specialized transcription factor. It aggressively modulates the genetic cascades dictating mucin production, ciliary motion, and localized inflammatory responses. By forcefully downregulating destructive pro-inflammatory cytokines while simultaneously restoring optimal ciliary sweeping action, it rapidly halts chronic lung degradation and catalyzes sweeping alveolar regeneration.

C16 compounds

Long-acting amylin analog at AMYR (CALCR+RAMPs). Area postrema satiety and gastric emptying, complementary to GLP-1 in CagriSema trials.

CagriSemacagrilintide semaglutide · REDEFINE trialStackMixed (~7-8 days each component)Cagrilintide 2.4 mg + Semaglutide 2.4 mg/week1× weekly (combined injection)

Fixed-ratio amylin analog plus GLP-1 RA. Two receptors, one trial product. Not a DIY dual-vial protocol.

CardiogenAla-Glu-Asp-Arg · AEDRBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Cardiogen infiltrates the highly demanding environment of cardiac myocytes, binding directly to regulatory DNA sequences. It executes a profound epigenetic overhaul by upregulating the synthesis of critical contractile proteins (like actin and myosin) and forcing massive mitochondrial biogenesis within the heart muscle. Simultaneously, it triggers hyper-potent anti-apoptotic pathways, ruthlessly preventing cardiac cell death under severe ischemic or oxidative stress.

CartalaxAla-Glu-Asp · AEDBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Functioning as a targeted genetic trigger within the joint space, Cartalax penetrates the heavily avascular (bloodless) environment of articular cartilage, entering the nucleolus of dormant chondrocytes. By binding directly to specific DNA promoter regions, it forces a massive, sudden upregulation in the transcription of genes strictly responsible for synthesizing Type II collagen and complex proteoglycans. This epigenetic switch fundamentally forces the cartilage to drastically increase its own structural density and shock-absorbing matrix.

CerebrolysinFPE 1070Cognitive~2-4 hours (peptide mix)5-30 mL/day (IV/IM)1× daily for 10-20 days

Low-molecular-weight porcine brain hydrolysate. Mixture identity. Not a single CAS sequence you can verify like BPC-157.

CerlutenBrain Peptide Complex · CNS CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Functioning via direct tissue-specific targeting, Cerluten's exact sequence matches deliver raw epigenetic data straight to exhausted human neurons. Once reaching the cortex, they bind to regulatory DNA sequences, forcefully reactivating silenced genes. This catalyzes a massive resurgence in the localized synthesis of essential neurotransmitters, dramatically enhances synaptic plasticity, and upregulates endogenous neuroprotective enzymes to shield against ongoing oxidative brain damage.

CetrorelixCetrotide · cetrorelix acetateClinical~5 hours (0.25 mg single SC; longer with repeat doses)0.25 mg SC once daily (Cetrotide kit) until hCG trigger1× daily during stimulation (IVF)

Competitive GnRH-receptor antagonist: immediate LH/FSH suppression without the flare of GnRH agonists. Linear SC kinetics in the labeled 0.25–3 mg range.

ChelohartHeart Extract Bioregulator · Cardiac CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Unlike synthetic single-peptides, Chelohart delivers a broad-spectrum payload of organ-specific short peptides and nucleoproteins directly to aging human cardiomyocytes. It provides the exact raw epigenetic data required to re-initiate stalled cellular metabolism. By binding to dormant regions of the cardiac genome, it forces an overarching normalization of contractile rhythm, ramps up local ATP production, and drastically increases the heart's resistance to sudden ischemic trauma.

ChitomurBladder Extract Bioregulator · Bladder CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Operating via the principle of exact tissue-matching, Chitomur's organ-specific peptide fractions migrate to the bladder and penetrate both the smooth muscle (detrusor) and the urothelium. Once inside the nucleus, they trigger an immense epigenetic reactivation of youthful structural genes. This forcefully ramps up the synthesis of fresh collagen and elastin within the bladder wall, restoring powerful contractility and fundamentally eliminating age-related urinary dysfunction.

ChonlutenGlu-Asp-Gly · EDGBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Chonluten boasts near-instantaneous penetration into the nuclei of struggling lung epithelial cells. Functioning as a high-affinity epigenetic trigger, it violently upregulates the genetic transcription responsible for producing pulmonary surfactant and localized mucosal immunoglobulins (like IgA). This mechanism sharply suppresses chronic bronchial inflammation while forcing a massive, accelerated wave of alveolar cell regeneration.

CJC-1295 (no DAC)Mod GRF(1-29) · Modified GRFGH Secretagogue~30 minutes100-300 mcg/injection1-3× daily

Tetrasubstituted GRF(1-29) lasts longer than native GHRH because of DPP-4-resistant substitutions, not because of albumin DAC. Pulse is minutes-class. PMID 16352683 on older catalog cards is the DAC paper; do not paste it as Mod GRF PK.

CJC-1295 + IpamorelinCJC/IPA · Mod GRF + ipamorelinStack~30 min (CJC no-DAC) / ~2 hours (ipamorelin)100-200 mcg CJC no-DAC + 200-300 mcg ipamorelin per injection1-2× daily (empty stomach, often before bed)

CJC no-DAC agonizes GHRH receptors (pulse amplitude). Ipamorelin agonizes GHS-R1a with a relatively clean cortisol/prolactin profile versus older GHRPs. Together they are meant to mimic a physiological GH pulse. Not FDA-approved as a combination.

CJC-1295 with DACCJC-1295 DAC · Modified GRF(1-29) with DACGH Secretagogue5.8-8.1 days1000-2000 mcg/week1-2× weekly

A 30-amino acid synthetic GHRH analog modified with a maleimidopropionic acid complex (DAC). This complex covalently bonds directly to human serum albumin (Cys34), artificially extending the peptide's half-life to roughly 8 days. Unlike physiological pulsation, DAC induces a persistent "GH bleed" - a continuous, relentless agonism of pituitary somatotrophs, establishing drastically elevated IGF-1 troughs while bypassing the strict constraints of somatostatin signaling.

CortagenAla-Glu-Asp-Pro · AEDPBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Operating deep within the central nervous system, Cortagen seamlessly traverses the blood-brain barrier and infiltrates the nuclear envelope of cortical neurons. It directly binds to highly specific, complementary DNA sequences, acting as an aggressively potent transcription factor. This interaction physically forces the un-silencing of genes strictly responsible for synthesizing massive volumes of Brain-Derived Neurotrophic Factor (BDNF) and endogenous antioxidant enzymes, dramatically shielding fragile synapses from lethal hypoxic and excitotoxic cascades.

CortexinBrain Peptide Complex · Neuropeptide PreparationNeuroprotective~30-60 minutes (estimated)5-10 mg/day IM1× daily for 10-20 days

By delivering hundreds of low-molecular-weight (<10 kDa) neuropeptides across the blood-brain barrier, Cortexin exerts a total, overarching neuromodulatory effect. It aggressively throttles lethal glutamate excitotoxicity, which destroys neurons post-injury. Simultaneously, it exerts profound neurotrophic actions mimicking both BDNF and NGF, physically forcing the repair of axonal membranes, promoting massive synaptic plasticity, and forcefully correcting localized GABAergic/glutamatergic imbalances.

CrystagenGlu-Asp-Pro · EDPBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Possessing a molecular structure specifically tailored to match precise immune-regulatory DNA sequences, Crystagen slips into the nucleus of exhausted lymphocytes and macrophages. By triggering aggressive chromatin remodeling, it reactivates highly specific genetic cascades dormant in aging individuals. This epigenetic activation forces the extreme, rapid proliferation and functional maturation of systemic T and B lymphocytes, violently enhancing the organism's raw phagocytic capacity while strictly stabilizing chaotic pro-inflammatory cytokine output.

D4 compounds
DesmopressinDDAVP · MinirinClinical3 hours10-40 mcg/day (intranasal) or 0.1-0.4 mg oral1-3× daily

Desmopressin acts as a hyper-selective agonist exclusively targeting the V2 receptors located deep within the renal collecting ducts. Upon activation, it forces a massive, immediate translocation of Aquaporin-2 water channels to the apical membrane, brutally locking down free water excretion and driving intense fluid reabsorption. Secondarily, it forces endothelial cells to dump massive reserves of von Willebrand factor (vWF) and Factor VIII into the bloodstream, triggering rapid hemostasis.

DihexaN-hexanoic-Tyr-Ile-(6) aminohexanoic amideCognitive~2-4 hours (estimated)10-40 mg/day (oral/intranasal)1× daily

Angiotensin-IV analog reported to act at HGF/c-Met in preclinical synaptogenesis work. Assay potency versus BDNF is not a human cognition multiplier.

DSIPDelta Sleep-Inducing PeptideSleep~7-8 minutes100-300 mcg before bed1× daily before bed

Historical neuromodulator papers around NREM architecture and HPA. Short t½ is why bedtime shots are folklore, not a depot hypnotic.

DulaglutideTrulicity · LY2189265GLP-1~5 days0.75-4.5 mg/week1× weekly

GLP-1 analog fused to IgG4 Fc for weekly exposure. T2D and CV-outcomes literature is branded Trulicity.

E6 compounds
EloralintideLY3841136 · Lilly eloralintideGLP-1Investigational (long-acting amylin)Investigational - sponsor protocol onlyTrial schedules only

Selective amylin-pathway agonism in a Lilly long-acting construct. Obesity and metabolic programs are sponsor-owned; gray-market fill is not that material.

EnclomipheneAndroxal · EN-CLOHormone~10 hours12.5-25 mg/day (oral)1× daily (oral)

Operating as a highly specific receptor antagonist, Enclomiphene binds seamlessly to estrogen receptors in the hypothalamus and pituitary gland, physically blinding them to circulating estrogen. Believing estrogen (and therefore testosterone) is pathologically low, the brain panics and violently upregulates the release of GnRH. This forces the pituitary to unleash massive waves of LH and FSH, aggressively over-stimulating the Leydig cells to manufacture raw, natural testosterone while fully maintaining spermatogenesis.

EndolutenPineal Gland Extract Bioregulator · Pineal CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Endoluten targets the absolute apex of the endocrine hierarchy: the pinealocyte. Escorting organ-specific epigenetic regulators directly into the pineal gland, it forcefully binds to the DNA regions governing melatonin production. By radically upregulating transcription of rate-limiting enzymes like AANAT, it restores youthful, massive surges of endogenous melatonin, which in turn acts as a systemic cascade trigger to reset the entire neuroendocrine system and halt telomere degradation.

EpitalonEpithalon · AEDG peptideLongevity~2-4 hours (estimated)5-10 mg/day1× daily for 10-20 days, cycle 2-3× per year

AEDG tetrapeptide in the Khavinson pineal line. Telomerase and melatonin papers are the school’s published frame. Not a Hayflick-limit bypass and not a Western longevity RCT. Epithalamin extract is a different product.

EpithalaminEpithalamine · Natural Epitalon extractKhavinson~3 hours5-10 mg IM1× daily for 10-20 day cycles

Containing a massive, full-spectrum matrix of pineal nucleoproteins (including naturally occurring Ala-Glu-Asp-Gly), Epithalamin executes total epigenetic domination. Slipping into pinealocytes, it violently un-silences the promoter regions for the AANAT enzyme, restoring massive, youthful melatonin synthesis. Concurrently, it penetrates systemic somatic cells to activate Telomerase, forcing the physical elongation of chromosomal telomeres and actively defying the Hayflick limit of cellular division.

ExenatideByetta · BydureonGLP-1~2.4 hours (Byetta) / ~2 weeks (Bydureon ER)5-10 mcg twice daily (Byetta) or 2 mg weekly (Bydureon)2× daily (IR) or 1× weekly (ER)

Synthetic exendin-4. IR is micrograms twice daily; ER is a microsphere depot. DPP-4 resistant because it is not human GLP-1.

F4 compounds
FGLNCAM FG-loop · FG loop peptideCognitiveShort (NCAM mimetic peptide; SKU PK unpublished)Research; vendor nasal/SC ranges are not a labelNot established

FGL is a 15-aa sequence from NCAM that can interact with FGF receptors in published neural-plasticity work. Community “nootropic stack” use is off that literature.

Follistatin 315FST-315 · FST315Recovery~hours (circulating isoform; human peptide-SKU PK unpublished)100-300 mcg/day (research; same ballpark as FST-344 community use)1× daily for short research cycles

Follistatin binds myostatin (GDF-8) and activins, blocking ActRIIB. Isoform 315 vs 344 changes localization more than the ligand set. Research-chem identity is often unverified.

Follistatin 344FS-344 · FollistatinRecovery~3-6 hours (estimated)100-300 mcg/day1× daily for 10-30 days

Operates as a high-affinity binding protein. Follistatin 344 aggressively intercepts, binds to, and permanently neutralizes TGF-beta family ligands - specifically Myostatin (GDF-8) and Activin - before they can successfully dock with the Activin type IIB receptor (ActRIIB) on muscle tissue. By physically blockading this negative feedback loop, the intracellular SMAD signaling cascade is silenced. Consequently, satellite cells are released from their dormant state, proliferating violently and fusing into massive new muscle fibers unencumbered by natural genetic growth brakes.

FOXO4-DRIFOXO4-D-Retro-Inverso · ProxofimLongevity~2-6 hours (estimated)5-20 mg/kg body weightEvery 3 days × 3 doses (protocol)

Designed to disrupt FOXO4–p53 interaction in senescent cells so p53 can drive apoptosis in that model. Mouse clearance of senescent cells is not a human anti-aging NDA.

G12 compounds
GHKGHK Basic · Gly-His-LysCosmetic~1–2 hours (estimated; same class as GHK-Cu without the metal)1-3 mg/day (injectable research) or topical 0.5–2%1× daily

GHK is an endogenous matricryptic tripeptide. Copper-free material can still bind ambient copper in tissue; that is chemistry, not proof that a Basic SKU equals Pickart’s GHK-Cu dataset.

GHK-CuCopper peptide · Glycyl-L-histidyl-L-lysine:copper(II)Skin~1-2 hours (estimated)1-3 mg/day (SC) or topical1× daily

Endogenous matricryptic tripeptide that binds Cu2+. Collagen/MMP language is the cosmetic and explant literature. Not Botox and not a telomere drug.

GhrelinGHRL · LenomorelinGrowth Hormone0.5 hours1-5 mcg/kg IV (research)Per study protocol

Functioning as a master metabolic and endocrine switch, Ghrelin actively crosses the blood-brain barrier to violently agonize GHS-R1a receptors localized in the hypothalamic arcuate nucleus. This triggers NPY and AgRP neurons to forcefully stimulate a voracious appetite. Simultaneously, it strikes the anterior pituitary to unleash a massive dumping of stored Growth Hormone, while independent vagal nerve activation drives profound systemic anti-inflammatory responses and deep cardiovascular protection.

GHRP-2Growth Hormone Releasing Peptide 2GH Secretagogue15-60 minutes100-300 mcg/injection2-3× daily

GHS-R1a hexapeptide (pralmorelin). Stronger GH pulse than GHRP-6; still off-target cortisol/prolactin versus ipamorelin.

GHRP-6Growth Hormone Releasing Peptide 6GH Secretagogue15-60 minutes100-300 mcg/injection2-3× daily

GHS-R1a hexapeptide. GH pulse plus ghrelin-pathway appetite, with cortisol and prolactin elevation versus ipamorelin.

GlandokortAdrenal Gland Extract Bioregulator · Adrenal CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Bypassing surface-level symptom management, Glandokort delivers exact organ-specific epigenetic instructions directly into the cells of the human adrenal cortex. By penetrating the nucleus, it resets the local DNA transcription rates for steroidogenic enzymes. This action forcefully stops the chaotic over-secretion of stress-induced cortisol and simultaneously upregulates the youthful synthesis of DHEA and aldosterone, permanently rebooting the entire stress-response architecture from the ground up.

GLOW StackGLOW peptide blend · GHK-Cu BPC-157 TB-500 stackStackMixed (1.5–4 hours per component)Advertised 70 mg 5:1:1 cake: 10 U ≈ 2.33 mg total from 3 mL. Separate-vial folklore differs.Pre-blend: daily in community logs. Separate vials: independent schedules.

Three research SKUs in one bottle. GHK-Cu is a copper tripeptide. BPC-157 is a 15-mer. TB-500 as sold is usually Ac-LKKTETQ, not full thymosin β4. Complementary marketing is not a combination trial.

GlutathioneGSH · L-GlutathioneLongevity~1.6 hours200-600 mg (SubQ/IV)1-3× weekly

Operating as a potent electron donor, Glutathione relentlessly seeks out and neutralizes horrific Reactive Oxygen Species (ROS), peroxides, and lipid radical cascades before they can shatter cellular DNA. Within the liver, it acts as the principal substrate for Glutathione S-transferase (GST), binding directly to lethal neurotoxins, xenobiotics, and heavy metals (via its sulfhydryl group), transforming them into highly water-soluble compounds that are rapidly and safely forcibly excreted via the renal system.

GonadorelinGnRH · LHRHRecovery~4 minutes100-500 mcg/day1-2× daily

Operates as a direct agonist at the GnRH receptor in the anterior pituitary gland. To remain effective, Gonadorelin MUST be administered in sharp, intermittent pulses to mimic natural hypothalamic bursts. This pulsatile rhythm prevents receptor downregulation, forcing the pituitary to continuously pump immense volumes of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) into the bloodstream. These gonadotropins subsequently surge the testes, aggressively stimulating Leydig cells to manufacture testosterone and Sertoli cells to sustain spermatogenesis.

GotratixMuscle Extract Bioregulator · Skeletal Muscle CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Functioning entirely via epigenetic command, Gotratix bypasses androgen receptors completely. Its tissue-specific peptides infiltrate struggling skeletal myocytes, binding to the highly specific DNA promoters that govern muscle repair. This violent epigenetic reactivation triggers rolling cascades of new contractile protein synthesis, aggressively awakens dormant satellite cells for new muscle fiber creation, and forces systemic mitochondrial biogenesis within the muscle tissue to drastically boost raw endurance.

GPL FemmeGPL® Femme · GPL Femme complexStackMixture (kit - not a single PK)Kit insert (oral capsules)Manufacturer 10–30 day courses

No single mechanism. Kit of Cytomax organ complexes. Not estradiol.

GPL ManGPL® Man · GPL Man complexStackMixture (kit - not a single PK)Kit insert (oral capsules)Manufacturer 10–30 day courses

No single mechanism. Each constituent is a tissue-specific peptide complex. Open the kit into the six leaves.

H6 compounds
hCGHCG · human chorionic gonadotropinhormonal~32–33 hours (SC/IM terminal)250-500 IU 2–3×/week (male hypogonadism / TRT adjunct); fertility doses are indication-specific2–3× weekly (SC or IM)

hCG binds LH/hCG receptors on testicular Leydig cells (testosterone) and ovarian theca/luteal cells (ovulation and luteal support). Urinary products are calibrated in USP/IU; do not convert IU to milligrams without the product’s stated specific activity.

HexarelinExamorelinGH Secretagogue~70 minutes100-200 mcg/injection1-2× daily

GHS-R1a hexapeptide with a large GH pulse and faster tachyphylaxis than later GHRPs. Cardiac literature is separate from a reconstitution hobby.

HGH Fragment 176-191AOD-9401 · Fragment 176-191Fat Loss~30 minutes250-500 mcg/day1-2× daily (fasted)

C-terminal GH snippet studied for lipolytic signaling. Do not launder full GH or tesamorelin VAT percentages onto this fragment.

HonlutenLung Extract Bioregulator · Pulmonary CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Possessing the exact biological signature required for lung tissue, Honluten's organ-specific nucleoproteins rapidly penetrate human respiratory epithelium. Once inside the nucleus, they act as massive epigenetic switches, forcing struggling alveolar cells to exponentially increase the endogenous production of pulmonary surfactant. They simultaneously rewrite the local genetic expression to halt chronic autoimmune inflammation, allowing the lungs to literally rebuild their own delicate mucosal barrier.

HumaninHN · Mitochondrial Peptide HumaninLongevity~30 minutes1-5 mg/day (research)1× daily

Operates both intracellularly and extracellularly through dual neuroprotective pathways. Extracellularly, it binds forcefully to a complex consisting of CNTFR/WSX-1/gp130, activating the formidable neuro-preservation STAT3 signaling cascade. Intracellularly, Humanin specifically intercepts and aggressively binds to the pro-apoptotic protein BAX (Bcl-2-associated X protein). By neutralizing BAX, it physically prevents the devastating release of cytochrome c from the mitochondria, abruptly halting the cellular execution sequence before the neuron can die.

Humanin-HNGS14G-humanin · HNGLongevityShort (parent humanin ~30 min; HNG potency ≠ longer t½)Research; parent humanin community range 1-5 mg is not an HNG label1× daily (research)

Parent humanin binds a CNTFR/WSX-1/gp130 complex and can intercept BAX. S14G increases potency in published models. That is analog SAR, not a new MDP with its own human PK package.

I3 compounds
IGF-1 DESDes(1-3) IGF-1 · Des-IGF-1Growth Factor~20–30 minutes (plasma)20-50 mcg (research; local/site injection)Training days (research use)

Truncation at residues 1–3 reduces IGFBP sequestration so more peptide is free to agonize IGF1R (PI3K/AKT/mTOR). The short half-life is why community use is local rather than systemic. Hypoglycemia risk is real - same receptor family as insulin.

IGF-1 LR3Long R3 IGF-1 · Insulin-like Growth Factor 1 Long R3Growth Factor~20-30 hours20-100 mcg/day1× daily

N-terminal extension plus Arg3 substitution reduce IGFBP sequestration so more analog is free at IGF1R (PI3K/AKT/mTOR). Hours-class t½ is why dosing is unforgiving compared with DES. Same receptor family as insulin.

IpamorelinGH Secretagogue~2 hours100-300 mcg/injection1-3× daily

Operates as a highly selective agonist of the ghrelin/growth hormone secretagogue receptor (GHSR-1a). Unlike GHRP-6 or GHRP-2, Ipamorelin's molecular structure is entirely devoid of the lipogenic or adrenocorticotropic side effects; it forcefully stimulates the pituitary to release a steady, prolonged pulse of GH without simultaneously triggering the adverse downstream release of cortisol, aldosterone, or prolactin.

KisspeptinKisspeptin-10 · KP-10Sexual Health~28 minutes100-500 mcg/dose1-2× daily

Functions as the exclusive agonist for the KISS1R (GPR54) receptor located precisely on the GnRH-secreting neurons within the hypothalamus. Upon binding, Kisspeptin violently depolarizes these neurons, forcing an overwhelmingly strong, massive surge of endogenous Gonadotropin-Releasing Hormone (GnRH). This upstream cascade inherently triggers a perfectly balanced, pulsatile release of LH and FSH from the pituitary, orchestrating dramatic downstream intra-testicular testosterone synthesis and robust spermatogenesis without disrupting the body's natural homeostatic rhythms.

Kisspeptin-10KP-10 · Metastin 45-54Hormone~3.6 minutes0.3-1 nmol/kg IV bolus (research)Research protocol (IV infusion)

Kisspeptin-10 bonds aggressively to the KISS1R (GPR54) receptors situated directly on Gonadotropin-Releasing Hormone (GnRH) neurons within the hypothalamus. This binding acts as the spark that ignites the entire reproductive cascade. It forces the GnRH neurons to fire in massive, healthy pulses, which subsequently commands the pituitary gland to dump luteinizing hormone (LH) and follicle-stimulating hormone (FSH) into the bloodstream, powerfully reigniting suppressed gonadal function.

KLOW StackKLOW peptide blend · GHK-Cu BPC-157 TB-500 KPV stackStackMixed (0.5–4 hours per component)Advertised 80 mg 50/10/10/10 cake: 15 U ≈ 4 mg total from 3 mL. COA first.Pre-blend: daily in community logs. Separate vials: independent schedules.

Adds KPV (α-MSH fragment) to GHK-Cu + BPC-157 + TB-500 7-mer. Each leaf has its own honesty file. The bottle does not inherit all four literatures.

KPVLysine-Proline-Valine · Alpha-MSH FragmentRecovery~30 minutes (estimated)200-500 mcg/day1-2× daily (or topical/oral)

KPV easily penetrates the cell membrane and translocates directly into the cell nucleus. Its primary operating mechanism is the aggressive, direct suppression of the NF-κB (Nuclear Factor kappa-light-chain-enhancer of activated B cells) transcription cascade - the definitive master switch for systemic inflammation. By silencing NF-κB, KPV instantly halts the production of horrific pro-inflammatory cytokines, especially TNF-α, IL-6, and IL-1β, rapidly reversing inflammatory storms while displaying notable antimicrobial efficiency against species like C. albicans.

KyotorphinL-Tyrosyl-L-Arginine · Tyr-ArgNeuroprotective~0.3 hours1-10 mg ICV/intranasal (research)Per study protocol

Instead of directly agonizing massive systemic opioid receptors, Kyotorphin binds to its own highly specific Gi-protein-coupled receptor. This triggers a massive, localized synaptic release of endogenous Met-enkephalin. Concurrently, Kyotorphin violently blocks DPP-III (the enzyme that destroys enkephalins), heavily dampens excitotoxic NMDA receptor activity, and physically interferes with the pathogenic aggregation of amyloid-β plaques within brain tissue.

L9 compounds
Lactoferricin BLfcinB · bovine lactoferricinAntimicrobial~1-2 hours (estimated)50-250 mcg (research)Per study protocol

Existing as an incredibly dense, amphipathic β-hairpin loop carrying a massive (+8) positive charge, Lactoferricin B executes a devastating electrostatic assault. It violently binds to the negatively charged lipopolysaccharides (LPS) of Gram-negative bacteria, physically shattering their membrane integrity and inducing explosive lysis. Beyond bacteria, it is capable of penetrating the membranes of specific cancer cells, directly triggering catastrophic mitochondrial depolarization and forcing immediate cellular apoptosis.

LarazotideAT-1001 · Larazotide acetateClinical~4-6 hours (estimated)0.5-1 mg 3× daily (oral)3× daily (oral, before meals)

When intestinal linings detect gluten, they release zonulin - a signaling protein that violently disassembles the tight junctions mapping the gut wall. Larazotide acts as a highly specific zonulin receptor antagonist. By blocking zonulin from binding to the epithelial surface, it completely prevents the dangerous displacement of the critical ZO-1 tight-junction proteins. This fiercely maintains the impenetrable structural integrity of the intestinal lumen, locking toxic macromolecules and antigens out of the bloodstream.

LeuphasylPentapeptide-18 · Tyr-D-Ala-Gly-Phe-LeuCosmeticTopical cosmetic (not a systemic PK story)Topical 3–10% solutions (INCI cosmetic use)1-2× daily topical

Marketed as modulating acetylcholine release at expression muscles via an enkephalin-like motif. Evidence is cosmetic/in vitro, not a drug program. SNARE-targeting hexapeptides (Argireline/SNAP-8) are a different mechanism.

LeuprorelinLeuprolide · LupronClinical3 hours3.75-22.5 mg depot (monthly-quarterly)Monthly or every 3-6 months (depot)

Upon continuous administration, Leuprorelin delivers an unrelenting, non-pulsatile agonism to the GnRH receptors on the anterior pituitary. Following an initial, massive spike in Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), the pituitary receptors completely exhaust, downregulate, and permanently desensitize. This severs the HPTA axis, plummeting systemic testosterone and estrogen to profound, castrate-level zeros within 2 to 4 weeks.

LibidonProstate Extract Bioregulator · Prostate CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Acting strictly on the prostatic cellular level, Libidon delivers tissue-specific peptide fractions directly into the nucleus of human prostate epithelial cells. By forcefully modulating localized gene expression, it disrupts the abnormal, accelerated cellular proliferation responsible for prostate enlargement. This targeted epigenetic oversight re-establishes normal, restricted glandular function and dramatically reduces localized pro-inflammatory signaling, allowing the prostate to physically normalize its own architecture.

LiraglutideVictoza · SaxendaGLP-1~13 hours0.6-3 mg/day1× daily

GLP-1 analog with a fatty-acid chain and ~13 h half-life, once daily. Glucose-dependent insulin, glucagon suppression, delayed gastric emptying, central satiety. Same MTC/MEN2 class warning as later GLP-1 RAs.

LivagenLys-Glu-Asp-Ala · KEDABioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Livagen executes a highly disruptive epigenetic mechanism. As humans age, critical protective genes become tightly wound into inaccessible clusters called heterochromatin, silencing them permanently. Livagen physically inserts itself into the DNA structure of aging hepatocytes (liver cells) and lymphocytes, violently decondensing (unwinding) these pericentromeric heterochromatin regions. This action forcefully reactivates silenced ribosomal genes, instigating massive de novo synthesis of foundational detoxification enzymes and accelerating absolute hepatic tissue regeneration.

LixisenatideAdlyxin · LyxumiaGLP-1~3 hours10-20 mcg/day1× daily

Exendin-4 analog with a hexa-lysine tail. Short-acting; post-prandial glucose and gastric emptying are the labeled emphasis.

LL-37Cathelicidin · hCAP18Recovery~4 hours (estimated)50-200 mcg/day1× daily

Because LL-37 is highly amphipathic (carrying both hydrophilic and lipophilic properties), it effortlessly binds to and disintegrates the lipid membranes of offending bacteria, fungi, and enveloped viruses via catastrophic pore formation. Simultaneously, it engages formyl peptide receptor-like 1 (FPRL1) and modulates Toll-like receptor (TLR) signaling, deploying a highly coordinated swarm of neutrophils and macrophages to infection sites while aggressively suppressing pro-inflammatory cytokine storms.

M9 compounds
MacimorelinAEZS-130 · MacrilenGH Secretagogue~4-6 hours0.5 mg/kg (diagnostic) or 1-2 mg/day (research)1× daily (oral)

Oral ghrelin-mimetic peptidomimetic. Labeled use is a single AGHD stimulation test, not chronic GH optimization.

MariTideAMG 133 · AMG-133GLP-1Investigational (monthly-class program)Investigational - sponsor protocol onlyMonthly-class in Amgen program (not a research cake)

Combines GIPR antagonism with GLP-1R agonism in a long-acting construct. The public story is monthly obesity dosing under sponsor protocols — not a compounded weekly twincretin.

MatrixylPalmitoyl pentapeptide-4 · Pal-KTTKSCosmetic~6 hours (topical)2-8% topical solution1-2× daily (topical)

Matrixyl’s core KTTKS pentapeptide perfectly mimics a sheared collagen fragment, acting as a false alarm that violently triggers the skin’s wound-healing cascade. Outfitted with a palmitoyl lipid tail to ruthlessly penetrate the stratum corneum, it descends into the dermis and locks into integrin receptors on resting fibroblasts. This forces an immediate, rampant upregulation in the synthesis of structural Collagen I, III, IV, and vital extracellular matrix glycosaminoglycans.

MazdutideLY3305677 · IBI362GLP-1~6-7 days3-9 mg/week1× every 2 weeks

GLP-1 plus glucagon dual agonist. Glucagon arm is extra energy-expenditure language and extra monitoring, not a US pen.

Melanotan 1Afamelanotide · ScenesseClinical0.5 hours16 mg implant (sub-dermal, every 60 days)Every 60 days (implant)

MT-1 operates as a highly selective, sniper-like agonist exclusively targeting the Melanocortin-1 Receptor (MC1R) located directly on the surface of epidermal melanocytes. By completely bypassing the MC3R and MC4R receptors, MT-1 forces massive eumelanin synthesis and skin darkening entirely without triggering the intense libido spikes, spontaneous erections, or severe appetite suppression notoriously caused by the off-target receptor bleeding seen in Melanotan II.

Melanotan IIMT-2 · Melanotan 2Skin~1 hour250-500 mcg/day (loading)Daily (loading 2 weeks), then 1-2×/week maintenance

Non-selective melanocortin agonist. MC1R drives eumelanin. Area postrema and MC4R explain nausea and sexual side effects. Not a melanoma-prevention protocol.

MGFMechano Growth Factor · IGF-1EcRecovery~5-7 minutes100-200 mcg per site1× daily (post-training)

Upon precise local injection, MGF immediately saturates the extracellular space of the damaged tissue. Rather than inducing standard protein synthesis, it acts strictly as an extreme mitogenic trigger. It forces the local activation and hyper-proliferation of reserve satellite cells (muscle stem cells) at the exact site of injury. These rapidly dividing new nuclei ultimately fuse to existing muscle fibers, permanently increasing the muscle's cross-sectional growth potential long after the peptide has degraded.

MK-677IbutamorenGH Secretagogue~5 hours (IGF-1 elevation 24h)10-25 mg/day (oral)1× daily (oral)

Oral GHS-R1a agonist. Daily dosing can raise GH/IGF-1 for many hours. Appetite and insulin resistance are the documented trade, not a cutting GLP-1.

MOTS-cMitochondrial ORF of the 12S rRNA Type-cMitochondrial~4-6 hours (estimated)5-10 mg/week3-5× weekly

mtDNA-encoded 16-mer reported to act as a retrograde metabolic signal, including AMPK-linked glucose uptake in preclinical models. Folate-cycle / AICAR language is the paper mechanism, not a human indication.

N8 compounds
N-Acetyl Epitalon AmidateNAEA · Ac-Epitalon-NH2LongevityUnknown for this analog (parent epitalon PK is already thin)5-10 mg/day (vendor longevity protocols; analog-specific PK absent)1× daily for 10-20 day cycles (vendor)

Parent AEDG is a pineal tetrapeptide studied for telomerase/pineal claims. Acetyl + amide slow exopeptidases in principle. That is analog chemistry, not a second clinical program.

N-Acetyl Selank AmidateAcetylated Selank · N-Acetyl-SelankCognitive~60-90 minutes250-750 mcg/day (intranasal)1-2× daily

N-Acetyl Selank Amidate hits the same targets as Selank - enkephalin-degrading enzymes, BDNF, and GABA-A allosteric modulation. N-terminal acetylation and C-terminal amidation slow aminopeptidase and carboxypeptidase attack versus unmodified Selank. That is analog chemistry, not a second Phase 3 program.

N-Acetyl SemaxAc-Semax · NASCognitiveLonger than Semax (estimated; analog PK unpublished)200-600 mcg/day (intranasal)1-3× daily (intranasal)

N-acetylation reduces aminopeptidase attack on the ACTH 4–10 core. Downstream claims (BDNF, attention) are inherited from Semax papers, not from a dedicated NAS dataset.

N-Acetyl Semax AmidateNASA · NA-Semax AmidateCognitiveLonger than Semax (estimated; analog PK unpublished)250-750 mcg/day (intranasal)1-2× daily (intranasal)

Parent Semax (ACTH 4–10 heptapeptide) is associated with BDNF/NGF upregulation and monoamine modulation in Russian clinical literature. Acetylation and amidation slow exopeptidase cleavage. That is a formulation hypothesis, not a separate Phase 3 program.

NAD+Nicotinamide Adenine Dinucleotide · NADLongevity~45 minutes (IV)50-250 mg (SubQ) or 250-1000 mg (IV)1-3× weekly

Electron shuttle and substrate for sirtuins/PARPs in textbooks. Exogenous NAD+ pharmacokinetics are not a guarantee of nuclear SIRT1 activation as a clinical endpoint.

NMNnicotinamide mononucleotide · β-NMNMitochondrialOral precursor pharmacokinetics (not a peptide t½)Oral NAD+ precursor - not a peptide vialOnce daily oral (product-dependent)

Salvage-pathway precursor that cells convert toward NAD+. Raising a precursor is not the same as proving a longevity indication from a capsule.

NoopeptGVS-111 · omberacetamCognitiveMinutes-class parent; metabolites longer (oral/intranasal)Oral/intranasal research ranges - not a US nootropic NDA1–3× daily oral or nasal (community practice)

Preclinical work (Ostrovskaya 2008; Vakhitova 2016) reports hippocampal NGF/BDNF mRNA changes and selective HIF-1 reporter activation. Short parent exposure is why people do not treat it like a weekly GH peptide.

NormoftalRetina Cytogen · Ocular CytogenBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Synthetic short peptide aimed at retinal tissue in the Khavinson organ map. Sequence is not as publicly standardized in English as AEDG or KED - do not steal Vilon’s KE code.

Agonizes somatostatin receptors (mainly sst2/sst5), suppressing GH, insulin, glucagon, and various gut peptides. Plasma t½ ~1.8 hours versus 1–3 minutes for native somatostatin.

Orexin-AHypocretin-1 · HCRT-1Cognitive~30 minutes (IV class; nasal research SKUs unpublished)Intranasal vendor ranges only - not a narcolepsy prescriptionVendor nasal (typically daytime)

Orexin-A agonizes OX1R/OX2R to stabilize wakefulness. Native peptide PK and BBB limits are why medicinal chemistry moved to small-molecule OX2R agonists.

OrforglipronLY3502970 · ATTAIN trialGLP-1~25-50 hours12-36-45 mg/day (oral)1× daily (oral)

Non-peptide oral GLP-1R agonist. Survives the gut without SNAC. Not Rybelsus (oral semaglutide).

Defined short peptide in the Khavinson liver aisle. Official manufacturer organ is liver, despite the trade name. Do not file this under reproductive endocrinology.

OxytocinPitocin · OXTSexual Health~3-5 minutes (IV)10-24 IU (intranasal)As needed or 1-2× daily

Functions as a potent agonist at specific G-protein coupled oxytocin receptors heavily concentrated in the amygdala and ventromedial hypothalamus. Upon binding, it profoundly suppresses the hyper-reactivity of the amygdala - the brain's critical fear center - thereby actively blunting the release of Corticotropin-Releasing Hormone (CRH) and stalling the HPA axis stress cascade. Simultaneously, it modulates serotonergic and dopaminergic output, generating deep anxiolytic effects and reinforcing empathetic neural circuitry.

P18 compounds
P21P021 · CNTF-derived peptideCognitive~2-4 hours (estimated)500-2000 mcg/day (SC or intranasal)1× daily

CNTF C-terminal fragment. Preclinical neurotrophic and hypothalamic energy papers. Not FGL.

Palmitoyl Tripeptide-1Pal-GHK · Biopeptide CLCosmetic~6-8 hours (topical, estimated)100-500 ppm topical1-2× daily (topical)

This peptide utilizes the legendary Gly-His-Lys (GHK) sequence, which natively represents a sheared fragment of degraded collagen. By attaching a deep-penetrating palmitoyl lipid chain, the peptide slips effortlessly into the dermis. Once recognized by resting fibroblasts - specifically via TGF-β pathway modulation - it simulates massive extracellular matrix damage, forcing the panicked cells to aggressively over-synthesize fresh Collagen I, III, and hydrating glycosaminoglycans as a severe compensatory mechanism.

PancragenPancreas Bioregulator Tetrapeptide · Lys-Glu-Asp-TrpBioregulator~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

Operating precisely within the Islets of Langerhans, Pancragen penetrates the remaining viable pancreatic beta-cells. Binding to targeted DNA promoter regions, it forcefully reactivates genetic pathways that have been crushed by chronic high blood sugar. This epigenetic jolt drastically surges the localized synthesis of endogenous insulin and massively upregulates glucose transporter (GLUT) expression, physically increasing the cell's capacity to process glucose while halting apoptotic beta-cell death.

PE-22-28PE22-28 · spadin analog PE-22-28CognitiveNot established in humansResearch - no established human doseNot established

Studied as a TREK-1 potassium-channel modulator in depression models. Animal and early translational work do not become a labeled mood protocol.

PEG-MGFPEGylated Mechano Growth FactorRecovery~3-5 days (PEGylated)200-400 mcg/day2-3× weekly

The active MGF sequence completely bypasses the traditional IGF-1 receptor pathway utilized for mature cell hypertrophy. Instead, it acts as a hyper-specific proliferative signal, binding directly to an uncharacterized MGF receptor on dormant muscle satellite (stem) cells residing just outside the muscle fiber. This interaction violently awakens the satellite cells - forcing rapid, exponential cellular division and proliferation. The PEGylation ensures this proliferative signal remains active systemically for over 72 hours.

PemvidutideALT-801 · GLP-1/glucagon dual agonistGLP-1~6-7 days1.2-2.4 mg/week1× weekly

GLP-1/glucagon dual agonist. Liver-fat trial language is Phase 2 observation, not a MASH indication on this page.

Same BPC-157 sequence (GEPPPGKPADDAGLV). Arginate vs acetate changes formulation and possibly oral handling, not a new receptor target. Published animal literature is almost entirely the acetate/free peptide.

Pentosan PolysulfateElmiron · PPSClinical~4.8 hours100 mg 3× daily (oral) or 2 mg/kg IM3× daily (oral) or 1-2× weekly (IM)

Carrying a dense negative charge, Pentosan operates as a direct molecular replacement for destroyed glycosaminoglycan (GAG) layers. In the bladder, it physically adheres to the damaged, eroded uroepithelium, forming an impenetrable artificial shield against toxic, highly acidic urine. In synovial joints, it executes a severe anti-inflammatory blockade - crushing complement activation, completely freezing inflammatory coagulation cascades, and physically halting the fibroblast growth factors responsible for destroying articular cartilage.

PetrelintideZP8396 · Zealand petrelintideGLP-1Investigational (long-acting amylin)Investigational - sponsor protocol onlyTrial schedules only

Amylin-pathway satiety agonist designed for infrequent injection under sponsor protocols. Separate from GLP-1-only and dual GIP/GLP-1 programs.

Saturating the renal cortex, Pielotax delivers precise epigenetic blueprints directly to aging human podocytes and tubular epithelial cells. Inside the nucleus, these peptide fractions rapidly force the expression of genes responsible for the structural maintenance of the glomerular filtration barrier. This intense genetic regulation physically tightens the filtration mesh, stops pathological protein leakage (proteinuria), and comprehensively restores deep electrolyte balancing mechanisms.

PinalexPinalex Tab · ПиналексBioregulatorTablet blend (not a single PK)Vendor tablet course (oral)Per label

Blend: peptide fraction plus carotenoid antioxidants. Do not launder AREDS or Retinalamin data onto this SKU.

PinealonEDR · Glu-Asp-ArgCognitive~30 minutes (estimated)1–2 capsules/day (Cytomed) or 1–2 mg SC (research vial)1× daily for 10-30 day cycles

EDR tripeptide in the Khavinson pineal/CNS map. Gene-expression claims are the school’s published frame, not a Phase 3.

PNC-27PNC27 · p53 12-26-MRPClinicalNot established in humansNo established human dose - preclinical / cell-line research onlyNot established

Designed as an HDM-2-binding p53 fragment plus a membrane peptide. In published cell work it colocalizes with membrane HDM-2 on transformed cells and induces necrosis independent of nuclear p53. That is laboratory oncology, not a labeled therapy.

PramlintideSymlin · amylin analogGLP-1~48 minutes15-120 mcg per meal3× daily (before meals)

Pro25/28/29 amylin analog. Mealtime adjunct to insulin: gastric emptying, post-prandial glucagon, central satiety.

ProstamaxKEDP · Lys-Glu-Asp-ProBioregulator~minutes–hours (short Khavinson tetrapeptide class; SKU PK unpublished)1-2 mg/day (research / Russian bioregulator practice)1× daily for short courses

Short cytogen peptides are claimed to act as gene-expression signals in the source-organ model. Human evidence is the Khavinson literature, not an FDA program. Do not confuse the tetrapeptide with the tissue extract.

ProstatilenSamprost · VitaprostKhavinson~2 hours5-10 mg rectally or IM1× daily for 5-10 days

Prostatilen operates by delivering concentrated, low-weight nucleoproteins that penetrate directly into human prostate epithelial cells. Acting as intense epigenetic modulators, they force a sheer drop in destructive inflammatory cytokines (TNF-α, IL-6). Simultaneously, they aggressively un-silence genes controlling localized pelvic microcirculation and drastically rebuild the normal secretory chemistry of the prostate gland, physically eliminating leukocytic infiltration and tissue swelling.

PT-141Bremelanotide · VyleesiSexual Health~2.7 hours500-2000 mcgAs needed (max 1×/24h, max 8×/month)

Cyclic analog of MT-2 trimmed toward MC3/MC4. Hypothalamic melanocortin signaling, not nitric-oxide cavernosal plumbing. Non-selective enough that flushing and nausea still show up. Not Viagra.

PTD-DBMCXXC5-blocking peptide · PTD-DBM hair peptideCosmeticNot established in humans (topical mouse work)Topical / microneedle research solutions (vendor); no established human doseTopical per vendor protocol

CXXC5 binds Dishevelled and negatively regulates Wnt. PTD-DBM is a competitor peptide plus a cell-penetrating tag. In mice it accelerated hair regrowth and wound-induced hair neogenesis. Human AGA is not that model.

R2 compounds
RetatrutideLY3437943GLP-1~144 hours (6 days)1-12 mg/week1× weekly

Functions as a tri-agonist targeting GLP-1, GIP, and Glucagon receptors simultaneously. While GLP-1 and GIP pathways synergize to crush appetite, delay empty rates, and optimize insulin sensitivity, the addition of glucagon receptor agonism acts as a metabolic furnace. It aggressively drives mitochondrial lipid oxidation (fat burning), enhances hepatic lipid clearance, and elevates the basal metabolic rate, completely negating the metabolic slowdown normally associated with severe caloric reservoirs.

RetinalaminRetinal bioregulatorKhavinson~2 hours5 mg IM or parabulbar injection1× daily for 10 days

Injected adjacent to the ocular globe, Retinalamin's microscopic fractions easily diffuse into the retina. They penetrate the nuclei of failing photoreceptors and the crucial Retinal Pigment Epithelium (RPE). Serving as an absolute epigenetic switch, they violently downregulate localized oxidative stress markers, force massive localized vascular repair to reverse diabetic capillary dropout, and physically shield neural ganglion cells from impending apoptosis.

S19 compounds
SelankTP-7Cognitive~3 minutes (rapid metabolism)250-750 mcg/day (intranasal)1-3× daily (intranasal)

Tuftsin analog. Russian clinical use is anxiolytic/nootropic. Parent t½ is minutes; nasal delivery is the usual route. Not a benzodiazepine.

Selank + SemaxSemax Selank stack · nootropic stackStack~2–3 minutes each (parent peptides; nasal SKUs vary)Selank 250-750 mcg + Semax 200-600 mcg (intranasal; often split AM/PM)1-3× daily (intranasal)

Selank is studied for GABA-A allostery and enkephalin-peptidase effects. Semax is studied for BDNF/NGF and monoamine modulation. Stacking them is a catalog pairing, not a new INN.

SemaglutideOzempic · WegovyGLP-1~168 hours (7 days)0.25-2.4 mg/week1× weekly

Structurally engineered with a fatty acid diacid chain to prevent rapid degradation by the DPP-4 enzyme, achieving a 168-hour half-life. It agonizes GLP-1 receptors in the pancreatic beta cells to stimulate glucose-dependent insulin secretion while forcefully suppressing hepatic glucagon release. Centrally, it crosses the blood-brain barrier to bind hypothalamic receptors, dramatically delaying gastric emptying and nullifying pathological food-seeking behavior.

SemaxCognitive~2-3 minutes (rapid metabolism)200-600 mcg/day (intranasal)1-3× daily (intranasal)

ACTH 4–7 analog plus PGP (MEHFPGP). BDNF/NGF language is the mechanism essay, not a US neuroprotection NDA.

SermorelinGRF 1-29 · GerefGH Secretagogue~10-20 minutes200-300 mcg/day1× daily (before bed)

Functions as a highly specific agonist at the GHRH receptor located on the anterior pituitary gland. Being a truncated 29-amino-acid fragment of the endogenous 44-amino-acid GHRH molecule, it contains the exact functional core required for receptor activation. Its activation triggers an intracellular cAMP cascade within somatotrophs, provoking the synthesis and release of endogenous GH. Crucially, Sermorelin respects the body's somatostatin negative-feedback loop, making tachyphylaxis (receptor burnout) or dangerously high GH levels a physiological impossibility.

Sermorelin + Ipamorelin ComboSerm/Ipa Stack · GHRH + GHRP StackGH Secretagogue~10-30 min / ~2 hours100-300 mcg each per injection1-2× daily (before bed)

GHRH receptor plus GHS-R1a in one draw. Larger pulses than either alone is classic dual-receptor physiology, not a printed 2–5× trial endpoint at bedtime 200/200 mcg.

SetmelanotideImcivree · RM-493Weight Mgmt~11 hours1-3 mg/day1× daily

Operating downstream of leptin, Setmelanotide acts as a highly specialized molecular key designed to perfectly activate the Melanocortin-4 Receptor (MC4R) located in the hypothalamus. Unlike crude, dirty melanocortins like MT-2 that bleed onto MC1R (causing extreme tanning) or MC3R, Setmelanotide surgically hits only MC4R. This restores the critical leptin-melanocortin satiety cascade, successfully forcing the brain to register fullness.

SHLP2Small humanin-like peptide 2 · SHLP-2MitochondrialUnknown (MDP class; SKU PK unpublished)Research; no established human doseNot established

Encoded in the 16S rRNA region as a putative MDP. Published cell work shows isoform-specific effects versus humanin and other SHLPs. Transferring humanin doses onto SHLP2 is a category error.

SigumirCartilage & Bone Extract Bioregulator · Musculoskeletal CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Sigumir exerts absolute epigenetic control over the musculoskeletal system. Delivering organ-specific instructions to dormant osteoblasts and chondrocytes, it forcefully penetrates the cell nucleus. This triggers a massive, sudden un-silencing of the genes directly responsible for synthesizing Type II collagen, dense proteoglycans, and raw bone mineralization proteins. The result is the forced, accelerated biological reconstruction of the physical articular surface and internal bone density.

SLU-PP-332ERRγ Agonist · Exercise Mimetic CompoundMitochondrial~4-8 hours (estimated)5-25 mg/day (oral)1× daily

Acting as a highly selective agonist, SLU-PP-332 forcefully locks into and activates the Estrogen-Related Receptor Gamma (ERRγ). This master nuclear receptor normally only fires during intense exercise. Activation genetically rewires systemic metabolism, forcing massive de novo mitochondrial biogenesis, permanently switching substrate utilization towards ruthless fatty acid oxidation, and physically converting fast-twitch muscle fibers into highly vascularized, fatigue-resistant type I (slow-twitch) fibers.

Snap-8Acetyl octapeptide-3 · SNAP-8Cosmetic~4 hours (topical)3-10% topical solution2× daily (topical)

Snap-8 functions as a massively upgraded SNARE complex inhibitor. With its extended 8-residue sequence, it exerts a far superior, tighter lock on the SNAP-25/syntaxin interface. This intense steric hindrance results in an exceptional reduction of excitatory acetylcholine release at the neuromuscular junction, forcing a much deeper, profound paralysis of the superficial fascial musculature and drastically smoothing overlying epidermal tension.

SomatropinHGH · rhGHGH Secretagogue~3 hours (SC terminal; ~0.4 h IV)Prescription is weight/indication-based; research vials often 1-4 IU/day. Conversion: 1 mg = 3 IU (WHO somatropin standard)1× daily (evening SC) on labeled products

Binds GHR on liver and peripheral tissue, raising IGF-1 via hepatic and autocrine production, with effects on lipolysis, linear growth, and protein synthesis. SC absorption stretches apparent t½ to ~3 hours versus ~20 minutes IV.

SS-31Elamipretide · BendaviaMitochondrial~4 hours20-40 mg/day (clinical trials)1× daily

Szeto tetrapeptide that associates with cardiolipin on the inner mitochondrial membrane. Cristae / ETC stability is the published frame. Antioxidant marketing is downstream of that, not a vitamin.

SS-31 + MOTS-cElamipretide MOTS-c · mitochondrial stackStack~4 h (elamipretide) / hours-class (MOTS-c, estimated)Research vials vary; not the Forzinity Barth dose. MOTS-c often 5-10 mg/week in community protocolsSS-31 often daily in trials · MOTS-c several times weekly

SS-31 binds cardiolipin on the inner mitochondrial membrane. MOTS-c is a 16-aa mitochondrial ORF peptide studied as an AMPK-linked metabolic signal. The stack is a vendor pairing of two MDP-adjacent research SKUs.

StamakortStomach Extract Bioregulator · Gastric CytomaxBioregulator~30 minutes (estimated)1-2 capsules/day1-2× daily for 10-30 day cycles

Operating precisely within the stomach lining, Stamakort delivers targeted peptide fractions into the nuclei of struggling parietal and chief cells.
