Chitomur

Bladder Extract Bioregulator · Bladder Cytomax · Хитомур

Chitomur is the Cytomax bladder complex. Vesilut (Vesilute) is the synthetic bladder cytogen on the official NPCRIZ list - the SKU Western catalogs most often skip. Pielotax is kidney, not bladder.

How it works

Chitomur (A-12) is a Cytomax natural polypeptide extract from the urinary bladder wall of young calves. Urinary dysfunction - including overactive bladder, stress incontinence, nocturia, and urgency - affects an estimated 30–40% of adults over age 60. The underlying cause is often not hormonal but structural: progressive atrophy of the detrusor muscle's smooth muscle cells and deterioration of the urothelial (bladder wall epithelial) lining.

Chitomur delivers a targeted library of short peptide signals (<10 kDa) that penetrate bladder wall cell nuclei via the Khavinson epigenetic mechanism, reactivating genes responsible for smooth muscle tone regulation, collagen synthesis in the submucosal layer, and anti-inflammatory cytokine balance. Unlike anticholinergic medications (oxybutynin, solifenacin) that simply suppress bladder contractions pharmacologically, Chitomur works to restore normal tissue architecture and neuromuscular tone at the cellular level.

In Khavinson's protocols, Chitomur is paired with Pielotax (A-9, kidney) for comprehensive urological system support - since bladder dysfunction and renal filtration decline are frequently co-occurring in aging populations. Regular maintenance courses can meaningfully reduce urgency episodes and nocturia frequency.

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

Bladder aging is detrusor, urothelium, and the miserable overlap with prostate in men. Khavinson split kidney (Pielotax) from bladder (Chitomur) on purpose. The cytogen pair is Vesilut, which we now list as its own leaf so the 41 is not missing a manufacturer SKU.

This is not oxybutynin, not mirabegron, not a sling surgery.

Caveats

Bladder 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.

Chitomur: 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 Chitomur. 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 (Vesilut / Vesilute (bladder cytogen)), a different SKU. There is no pharmaceutical-extract SKU that is this capsule in a syringe.
Advantages
  • The defined-sequence vial in this aisle is the cytogen pair (Vesilut / Vesilute (bladder cytogen)), a different SKU.
  • There is no pharmaceutical-extract SKU that is this capsule in a syringe.
  • Reconstitute Vesilut (vesilute) if you bought the bladder cytogen. A Chitomur cake is a mis-ID. This is not oxybutynin or mirabegron.
Considerations
  • Chitomur 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 Chitomur: swallow the capsule with water. No reconstitution step and no 5 mg cake.
  • Bladder-wall Cytomax (Cytomed A-12). Pielotax is kidney. Vesilut is the cytogen Western catalogs most often skip. Samprost is a Prostatilen/prostate brand, not a second bladder extract.
  • Course-based (10–30 days, a few times a year in manufacturer folklore), not a daily forever drug.
Considerations
  • Bladder 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 Chitomur as oral capsules with water, about 30 minutes before meals. Bladder Cytomax complex, not Vesilut powder and not Pielotax (kidney). Pair: Vesilut / Vesilute. Not a labeled antimuscarinic. See a urologist for overactive bladder.

Timeline

Days 1–14

  • This site will not treat the named organ disease from a peptide page.
  • English-language V2 / analog bottles are a later commercial layer, not a Khavinson RCT.

Verdict

Chitomur is a Cytomax capsule complex from Urinary bladder. It is not the paired cytogen, not a 5 mg research cake, and not a US supplement monograph. The organ story is in the dossier on this page.

Interactions & Contraindications

Standard Cytomax capsule identity, not urology.

Frequently Asked Questions

Oral capsule or injection?▼
Chitomur 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 (Vesilut / Vesilute), not this complex. Do not run BAC math on a capsule SKU. Pielotax is kidney. Samprost is a Prostatilen/prostate brand, not a second bladder extract.
Chitomur vs Vesilut vs Pielotax?▼
Chitomur = bladder Cytomax. Vesilut = bladder cytogen. Pielotax = kidney Cytomax.
Overactive bladder drug?▼
Not a labeled antimuscarinic. See a urologist for OAB.
Why was Vesilut missing?▼
Western research-chem menus skip it. It is on the Cytomed cytogen poster. We added the leaf so the 41 is complete.
Reconstitution?▼
Not Chitomur. Vesilut if sold as cytogen powder.
Can Chitomur replace OAB medications?▼
Chitomur works at the tissue gene-expression level rather than blocking cholinergic receptors pharmacologically. It is not a substitute for prescription medications but is frequently used as a restorative adjunct or for long-term maintenance after symptom control is achieved. Always consult your physician.
Should I combine Chitomur with Pielotax?▼
Yes - the Khavinson urological system bundle pairs Chitomur (bladder) with Pielotax (kidneys) and Vladonix (immune). Since age-related urinary dysfunction often involves both filtration (renal) and storage (bladder), addressing both simultaneously is recommended.
