How it works

Cerluten (A-5) is a Cytomax natural polypeptide extract from the brain (cerebral cortex) of young calves, delivering a broad library of neurotrophic peptide signals targeting the human central nervous system. Cognitively, aging manifests as declining neuroplasticity, reduced production of BDNF (brain-derived neurotrophic factor), increased neuroinflammation, and accumulating oxidative damage to neurons - collectively causing the "brain fog," memory lapses, and processing speed decline that most adults over 50 experience.

Cerluten's peptide cocktail is conceptually similar to Cerebrolysin (injectable porcine brain hydrolysate used in stroke rehabilitation) and Cortexin (injectable bovine peptide used in Russian neurological medicine), but formulated for oral Cytomax delivery. The <10 kDa peptide fractions cross the gut barrier and reach the bloodstream, where they act on brain tissue gene expression via the Khavinson epigenetic mechanism - relaxing heterochromatin to reactivate genes encoding BDNF, nerve growth factor (NGF), and antioxidant enzymes in neurons and glial cells.

In the Khavinson bundle system, Cerluten is the anchor of the central nervous system stack: paired with Ventfort (A-3, blood vessels) for neurovascular delivery and Svetinorm (A-7, liver) for metabolic cleansing. The combination addresses both neuronal gene expression and the vascular/metabolic environment that neurons depend on. Athletes and high-performance professionals use Cerluten for cognitive resilience; gerontologists use it to slow age-related cognitive decline.

Used in bioregulator stacks

Manufacturer-style organ combinations - not FDA protocols. Every name is a live leaf.

The Khavinson school

Vladimir Khatskelevich Khavinson (1946–2024) spent five decades at what became the St. Petersburg Institute of Bioregulation and Gerontology arguing a simple, stubborn idea: aging is, in part, a failure of tissue-specific peptide signals, and those signals can be restored. The first products were not “peptides” in the Instagram sense. They were Cytamins - polypeptide fractions isolated from a named organ of young animals. Later commercial refinements of those fractions are sold as Cytomaxes (Cytomed / NPCRIZ): still mixtures, still oral capsules, still defined by the source organ rather than a single sequence. When the group identified short active motifs inside those mixtures, they synthesized them as Cytogens - di-, tri-, and tetrapeptides with a one-letter code (KE, AEDG, KED, EDR, KEDP, and so on).

That three-layer stack is the whole map. Cytamin / pharmaceutical extracts (Thymalin, Epithalamin, Cortexin, Retinalamin, Prostatilen) are the clinic-era injectables registered in the former Soviet pharmacopeia. Cytomaxes are the capsule complexes Cytomed still lists as a 21-SKU organ line. Cytogens are the defined synthetics. English-language educators, including Brenden Henry’s public writing at Peptide Science Institute, add a further commercial distinction - later analog SKUs (N-acetyl, amidate, “V2” complexes) sold as more stable or more diverse than the original Cytomed lots. That last layer is a product taxonomy, not a Khavinson paper. We describe it so readers are not gaslit by three bottles with the same organ name. We do not reproduce paid Peptide Mastery protocols, Precision Cell Method language, or anyone else’s course IP.

Full Cytamin → Cytomax → Cytogen map, literature limits, and how we counted 41

The mechanism Khavinson published is epigenetic, not receptor-agonist in the GLP-1 sense. Short peptides are claimed to enter nuclei, interact with DNA/histones, and reopen tissue-specific transcription that condensed with age (heterochromatin → euchromatin). Reviews in the Bulletin of Experimental Biology and Medicine and Neuroendocrinology Letters (PMID 14523363, 15677927, 23888677) are the citable core. Complementary GI pharmacology is not mystical: di- and tripeptides are PEPT1/LAT substrates, which is why oral capsules are even a conversation. What is not established in Western Phase 3 programs is organ-by-organ disease treatment, telomere reversal as a clinical endpoint, or the manufacturer claim that Cytomax is “a third stronger” than Cytogen. Those are NPCRIZ marketing sentences.

Khavinson’s group published hundreds of papers, many in Russian, many in the same journal family. That is a real literature. It is also a literature with limited independent Western replication, small n, and a habit of using one review PMID as a stamp on every organ. On this site a leaf earns its organ story, its Cytomax↔Cytogen pair, its sequence if it has one, and an honest sentence about what has not been shown. Reconstitution math belongs on cytogens sold as vials. Cytomax capsules do not get a fake 5 mg vial.

The 41 we treat as canonical are the 21 Cytomaxes on the public e-peptide/Cytomed list, the 12 Cytogens on that same commercial line (including Vesilut, which Western catalogs often drop), plus eight historically load-bearing molecules that sit beside the capsule SKUs: Epitalon, Vilon, Thymogen, Livagen, Cortagen, Prostamax, Thymalin, and Epithalamin. Honluten, Cortexin, Retinalamin, Prostatilen, Thymulin, N-acetyl-epitalon-amidate, Pinalex, and the GPL Man / GPL Femme kits are covered as adjacent - same school or same storefront, not padded into a fake 41.

Public English-language teaching (including Brenden Henry at peptidescienceinstitute.com) is cited as context, not copied. Paid Peptide Mastery / Peptide Salvation text stays theirs.

History of this molecule

CIS neurology had Cortexin as a hospital peptide extract for brain injury and encephalopathy long before “Cerluten” was a US warehouse label. Cerluten is the oral Cytomax complex for brain tissue. Cortagen is cortex tetrapeptide. Pinealon is the EDR tripeptide sitting on the pineal/CNS border.

Semax and Selank are Institute of Molecular Genetics / Russian nootropic peptides - related country, different program. Do not file Cerluten under “Russian nootropics” next to Semax as if they were one family.

Stroke, MCI, and epilepsy are not capsule indications in the US.

Caveats

Brain Cytomax is not a US dietary-supplement monograph and not a drug. The tissue-extract model means lot-to-lot composition is a fingerprint, not a single CAS number. English-language “V2” bottles that claim more peptide diversity are a later commercial layer (mass-spec marketing from specific brands) - they are not Khavinson’s 1990s papers. Animal-source capsules are inappropriate if the reader has a religious or allergy constraint on the source species. None of this replaces care for the actual organ disease.

Administration

Route / form
Oral capsules - swallowed with water. Cytomed Cytomaxes ship as capsules, not sublingual tablets and not lyophilized research vials.
Timing
Morning, with water, about 30 minutes before meals (empty stomach).
Empty stomach?
Yes - Empty stomach - about 30 minutes before meals. Cytomed boxes sometimes print “with food” because they are labeled as supplements; the manufacturer user-guide preference is before meals for absorption.

Cerluten: Not a research vial vs Oral capsule

Not a research vial
Bioavailability
Not applicable. This Cytomax SKU is not sold as a lyophilized research vial. There is no SubQ F% because Cytomed does not ship this complex as a cake.
Dose note
Do not reconstitute Cerluten. No BAC-water chart, no 5 mg vial math, no units-on-a-U-100 conversion. The defined-sequence vial in this aisle is the cytogen pair (Pinealon (EDR) and Cortagen (AEDP)), a different SKU. Cortexin is the pharmaceutical extract in this organ family (clinic-era injectable or other non-capsule form), not this Cytomax.
Advantages
  • The defined-sequence vial in this aisle is the cytogen pair (Pinealon (EDR) and Cortagen (AEDP)), a different SKU.
  • Cortexin is the pharmaceutical extract in this organ family (clinic-era injectable or other non-capsule form), not this Cytomax.
  • Reconstitute Pinealon or Cortagen if you bought those cytogens. Cortexin is the IM cortical extract, not this capsule. A Cerluten cake is a mis-ID.
Considerations
  • Cerluten is an oral capsule complex. It is not a 5 mg lyophilized research vial.
  • Inventing recon math for a zero-mg Cytomax vial is how people inject the wrong product.
  • Not an official Cytomed sublingual tablet, IM ampoule, or eye drop either.
Oral capsule
Bioavailability
Not quantified in a Western PK study. Official Cytomed form is a swallowed capsule. PEPT1/LAT transport is class biology for short peptides, not an F% for this tissue mixture.
Dose note
Typical Cytomed labeling: 1–2 capsules daily in 10–30 day courses, swallowed with water about 30 minutes before meals (empty stomach). Manufacturer protocol, not an FDA label. Some boxes print “with food” because they are labeled as supplements; the timing copy we use is before meals.
Advantages
  • Official form for Cerluten: swallow the capsule with water. No reconstitution step and no 5 mg cake.
  • Brain Cytomax: the oral complex. Not Semax, not a racetam, not Pinealon/Cortagen powder. CIS neurology’s extract is Cortexin.
  • Course-based (10–30 days, a few times a year in manufacturer folklore), not a daily forever drug.
Considerations
  • Brain Cytomax is a peptide mixture / lot fingerprint, not a single CAS. English “V2” bottles are a later commercial layer, not a Khavinson RCT.
  • Russian school literature is not an FDA organ-disease label.
  • Third-party lingual SKUs exist in the wild. We do not claim sublingual as the official Cytomed Cytomax form.
Recommendation: Swallow Cerluten as oral capsules with water, about 30 minutes before meals. Brain Cytomax complex, not Cortexin IM, not Pinealon, not Cortagen, and not Semax. Pair: Pinealon (EDR) and Cortagen (AEDP). Stroke, MCI, and epilepsy are not capsule indications in the US.

Frequently Asked Questions

Oral capsule or injection?▼
Cerluten is a Cytomax oral capsule: swallow with water, about 30 minutes before meals. It is not a 5 mg lyophilized research vial and not an official Cytomed sublingual tablet (third-party lingual SKUs exist in the wild). If you want a defined-sequence powder to reconstitute, that is the cytogen pair (Pinealon / Cortagen), not this complex. Do not run BAC math on a capsule SKU. Cortexin is the IM cortical extract. This is not Semax.
Cerluten vs Cortexin vs Cortagen vs Pinealon?▼
Cerluten = Cytomax brain complex. Cortexin = pharma extract. Cortagen = synthetic AEDP (cortex). Pinealon = synthetic EDR (CNS/pineal-adjacent).
Is this Semax?▼
No. Semax is a Melanocortin/ACTH(4-10) analog from a different Russian institute.
Stroke treatment?▼
Not a US-labeled treatment. Acute stroke is emergency care.
Reconstitution?▼
Not Cerluten capsules. Pinealon/Cortagen vials if you bought cytogens.
Is Cerluten comparable to Cerebrolysin?▼
They share the same core concept - a broad-spectrum hydrolysate of mammalian brain tissue delivering neurotrophic peptides. Cerebrolysin is a pharmaceutical-grade injectable from porcine brain (used in stroke / TBI medicine). Cerluten is an oral Cytomax supplement from bovine cortex for preventive and maintenance use. Cerebrolysin delivers faster and more concentrated action; Cerluten is superior for long-term oral maintenance.
What is the best stack with Cerluten?▼
The official Khavinson CNS bundle is Cerluten (A-5) + Ventfort (A-3) + Svetinorm (A-7). Ventfort ensures optimal cerebrovascular blood flow, and Svetinorm supports metabolic detoxification - both critical to creating the right environment for neuronal regeneration.
