Libidon
Prostate Extract Bioregulator · Prostate Cytomax · Либидон
Libidon is the Cytomax prostate complex. Prostatilen is the pharmaceutical extract. Prostamax is the synthetic tetrapeptide KEDP. Three products, one gland. Libidon is not tadalafil and not a testosterone booster.

How it works
Libidon (A-16) is a Cytomax natural polypeptide extract from the prostate gland of young male calves, targeting the human prostate to restore normal cellular function and tissue architecture through epigenetic gene regulation. The prostate is uniquely vulnerable to aging: BPH (benign prostatic hyperplasia) affects ~50% of men by age 60 and ~90% by age 85, while prostate inflammation (prostatitis) is estimated to affect 8–16% of men at any given time. Both conditions involve a common core pathology - dysregulation of prostate epithelial cell proliferation, inflammation signaling (NF-κB, COX-2), and DHT (dihydrotestosterone) receptor sensitivity.
Libidon delivers short peptide signals from bovine prostate tissue (<10 kDa) that enter prostate cell nuclei to reactivate age-suppressed genes governing: cell cycle regulation (p53, PCNA), anti-inflammatory cytokine balance (IL-10 upregulation, IL-6 downregulation), and proper epithelial differentiation. Critically, Libidon does not manipulate DHT or testosterone - it works downstream, at the level of cellular gene expression, to restore what a healthy prostate cell would naturally produce.
In Khavinson's Russian clinical trials, courses of prostate polypeptide bioregulators showed statistically significant improvement in BPH symptom scores (IPSS), reduced PSA variability, and better urinary flow rates. The protocol typically combines Libidon (A-16) with Pielotax (A-9, kidney) - since BPH-induced urinary obstruction has direct upstream effects on renal function.

Canonical 41Used 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 urology used prostate extracts (Prostatilen and relatives) for chronic prostatitis / BPH-adjacent complaints long before Reddit discovered KEDP. Libidon is the Cytomax capsule complex. Prostamax is the defined cytogen people reconstitute.
The name Libidon is marketing (libido). The tissue is prostate. If the buyer’s problem is erectile hemodynamics, they bought the wrong organ. If the problem is prostate aging, this is the aisle - still not a substitute for PSA, DRE, and actual urology.
Do not confuse prostate cytogen KEDP with thymic KE or vascular KED. One letter is a different molecule.
Caveats
Prostate 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. Rising PSA is a workup. A capsule is not finasteride.

Administration
Libidon: Not a research vial vs Oral capsule
- The defined-sequence vial in this aisle is the cytogen pair (Prostamax (KEDP)), a different SKU.
- Prostatilen is the pharmaceutical extract in this organ family (clinic-era injectable or other non-capsule form), not this Cytomax.
- Reconstitute Prostamax if you bought KEDP. Prostatilen is the extract (historically IM or rectal suppository). A Libidon cake is a mis-ID.
- Libidon 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.
- Official form for Libidon: swallow the capsule with water. No reconstitution step and no 5 mg cake.
- Prostate Cytomax. The name says libido; the tissue is prostate. Erectile hemodynamics is a different problem. Testoluten is testis.
- Course-based (10–30 days, a few times a year in manufacturer folklore), not a daily forever drug.
- Prostate 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.
Timeline

Limits of current evidence
- Cytomax SKUs are oral capsules. Do not run SubQ reconstitution math on a zero-mg vial.
- Lot-to-lot composition is a fingerprint, not one sequence.
- 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
Libidon is a Cytomax capsule complex from Prostate. 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
Urology first if there is an existing prostate condition.
