Visoluten
Eye Extract Bioregulator · Retinal Cytomax · Визолутен
Visoluten is the Cytomax eye-tissue complex. The pharmaceutical cousin is Retinalamin, used in Russian ophthalmology. The synthetic cytogen on the Cytomed line is Normoftal. This is not “eye drops of BPC-157.”

How it works
Visoluten (A-11) is a Cytomax natural polypeptide extract from the retinal and choroidal tissues of young calves, targeting human photoreceptors (rods and cones), retinal pigment epithelium (RPE), and Müller glia to restore age-silenced gene expression governing visual signal transduction, photoreceptor renewal, and RPE-mediated outer segment phagocytosis. The retina is the most metabolically active tissue in the body per gram of tissue - it has the highest oxygen consumption rate of any organ and is therefore extremely vulnerable to age-related oxidative stress and vascular compromise.
Age-related macular degeneration (AMD) - the leading cause of irreversible vision loss in adults over 50 - involves progressive dysfunction and death of RPE cells underneath the fovea, with subsequent loss of cone photoreceptors responsible for central vision. Visoluten delivers short peptide signals (<10 kDa) from bovine retinal tissue that enter RPE and photoreceptor nuclei to reactivate: PEDF (pigment epithelium-derived factor, a neuroprotective and anti-angiogenic protein produced by RPE), rhodopsin (the photopigment of rod photoreceptors), CRALBP (cellular retinaldehyde-binding protein for visual cycle maintenance), and RPE65 (the critical isomerase in the visual cycle converting all-trans retinyl ester to 11-cis retinol for photoreceptor regeneration).
Visoluten addresses retinal aging at the gene expression level - not through antioxidant supplementation (lutein, zeaxanthin) or anti-VEGF injections. It is used alongside Normoftal (Lys-Glu synthetic dipeptide targeting the same tissue via a different mechanism) in Khavinson's ocular longevity protocols.

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
Russian peptide ophthalmology is older than the US research-chem boom. Retinalamin (polypeptide extract of cattle retina) was a real hospital product for retinal dystrophy and degenerative disease in CIS practice. Visoluten is the oral Cytomax complex aimed at the same tissue class. Normoftal is the defined synthetic on the NPCRIZ cytogen list.
Western catalogs sometimes map Visoluten to Vilon because both start with V. That is a string-matching injury. Vilon is thymus KE. Visoluten is eye. If a blog table pairs Visoluten with Vilon, throw the table out.
The Khavinson frame is photoreceptor and retinal-pigment epithelium gene expression fading with age and light damage. The extract literature is stronger than the capsule-brand literature. Retinalamin papers should not be cited as if they were Visoluten RCTs, but they are the honest historical neighbor.
Henry-style English teaching will talk about vision peptides as epigenetic, not as anti-VEGF (that’s ranibizumab). Keep those mechanisms in different rooms.
Caveats
Retina 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
Visoluten: Not a research vial vs Oral capsule
- The defined-sequence vial in this aisle is the cytogen pair (Normoftal (retina cytogen)), a different SKU.
- Retinalamin is the pharmaceutical extract in this organ family (clinic-era injectable or other non-capsule form), not this Cytomax.
- Do not invent an intraocular or SubQ protocol for Visoluten capsules. Normoftal is the cytogen if you bought a defined-sequence vial. Retinalamin is the CIS ophthalmology extract (historically IM / parabulbar), a different product.
- Visoluten 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 Visoluten: swallow the capsule with water. No reconstitution step and no 5 mg cake.
- Ocular Cytomax (Cytomed A-11): swallowed capsule. Not eye drops, not intraocular recon, not AREDS2, and not Vilon (thymus KE).
- Course-based (10–30 days, a few times a year in manufacturer folklore), not a daily forever drug.
- Retina / eye 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.
