Stamakort

Stomach Extract Bioregulator · Gastric Cytomax · Стамакорт

Stamakort is the Cytomax stomach-mucosa complex. It is not BPC-157 (a 15-mer from gastric juice discovered in Zagreb). Same neighborhood of “gut lining,” completely different research programs.

How it works

Stamakort (A-10) is a Cytomax natural polypeptide extract from the gastric mucosa of young calves, targeting human stomach epithelial cells, parietal cells, and chief cells to restore age-silenced gene expression controlling gastric acid secretion, mucous barrier integrity, and gastric hormone production. The stomach faces a unique double challenge as we age: gastric acid production declines (hypochlorhydria, affecting an estimated 30% of adults over 60), while simultaneously the protective mucous barrier also weakens - making the stomach both less effective at digestion and more vulnerable to ulceration and H. pylori-mediated damage.

Stamakort delivers short peptide signals (<10 kDa) from bovine gastric tissue. These peptides penetrate stomach epithelial cell nuclei to reactivate transcription of genes encoding: H/K-ATPase (the proton pump responsible for gastric acid), pepsinogen (the digestive protease precursor secreted by chief cells), gastrin receptor components, and mucin glycoproteins (the gel layer protecting stomach walls). This is fundamentally different from both PPIs (which block acid further) and HCl supplementation (which adds acid exogenously) - Stamakort works to restore the stomach's own regulatory capacity.

In the Khavinson bundle system, Stamakort (A-10) is paired with Svetinorm (A-7, liver) for comprehensive upper GI and hepatic function - since gastric function and hepatic bile production are tightly coupled in the digestive cascade.

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

Khavinson gastric bioregulation is mucosa identity - chief cells, parietal cells, barrier. BPC-157 is Sikirić’s pentadecapeptide with a huge animal-wound literature and a US compounding mess. Putting Stamakort on a BPC page as “the Russian version” is fan fiction.

There is no Stamakort-equivalent cytogen on the 12-SKU NPCRIZ cytogen poster (those GI-adjacent synthetics are Ovagen/Livagen for liver). Stomach complex stands more alone than Ventfort/Vesugen.

Caveats

Gastric 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. Bleeding ulcer is an ED, not a 10-day capsule.

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.

Stamakort: 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 Stamakort. No BAC-water chart, no 5 mg vial math, no units-on-a-U-100 conversion. No dedicated cytogen on the 12-SKU NPCRIZ poster (none on the 12-SKU poster - not BPC-157, not a GI cytogen). Do not invent one. There is no pharmaceutical-extract SKU that is this capsule in a syringe.
Advantages
  • No dedicated cytogen on the 12-SKU NPCRIZ poster (none on the 12-SKU poster - not BPC-157, not a GI cytogen). Do not invent one.
  • There is no pharmaceutical-extract SKU that is this capsule in a syringe.
  • Do not steal BPC-157 vial math. Liver cytogens (Livagen / Ovagen) are not stomach. There is no Stamakort cytogen on the 12-SKU list.
Considerations
  • Stamakort 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 Stamakort: swallow the capsule with water. No reconstitution step and no 5 mg cake.
  • Stomach-mucosa Cytomax (Cytomed A-10). Same neighborhood as “gut lining,” completely different program from Sikirić BPC-157.
  • Course-based (10–30 days, a few times a year in manufacturer folklore), not a daily forever drug.
Considerations
  • Gastric mucosa 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 Stamakort as oral capsules with water, about 30 minutes before meals. Gastric-mucosa Cytomax complex, not BPC-157, not a PPI, and not a research vial. No stomach cytogen on the 12-SKU poster. Bleeding ulcer is an ED, not a 10-day capsule.

Frequently Asked Questions

Oral capsule or injection?▼
Stamakort 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 (none on the 12-SKU poster), not this complex. Do not run BAC math on a capsule SKU. This is not BPC-157. Liver cytogens are not stomach.
Is Stamakort BPC-157?▼
No. BPC-157 is a synthetic 15-amino-acid peptide from a gastric protein fragment (Sikirić). Stamakort is a Khavinson stomach-mucosa peptide complex.
Pair cytogen?▼
Not on the public 12-cytogen list. Liver cytogens are not stomach.
GERD cure?▼
No. PPI/H2 and workup for alarm symptoms remain standard.
Reconstitution?▼
No.
Can Stamakort help after stopping PPIs?▼
PPI discontinuation often causes rebound hypersecretion - the parietal cells have been suppressed for so long that they overcompensate when the drug is removed. Stamakort works to restore normal H/K-ATPase gene expression regulation, helping the gastric mucosa recalibrate rather than oscillating between suppression and overproduction.
Should I combine Stamakort with Svetinorm?▼
Yes - the Khavinson digestive system stack pairs Stamakort (stomach mucosa) with Svetinorm (liver/bile). Gastric acid secretion and hepatic bile flow are intimately coordinated by the cholecystokinin-secretin axis. Addressing both upstream (liver/bile) and downstream (stomach/digestion) improves the overall GI outcome.
