Epitalon, Khavinson short-peptide bioregulators, FOXO4-DRI, and longevity cofactors (NAD+, glutathione) studied for aging and tissue-specific regeneration.
Most of this category comes from a single research program: the work of Vladimir Khavinson and the Saint Petersburg Institute of Bioregulation and Gerontology on ultra-short peptide bioregulators, which the group's papers call cytogens. The organizing claim is that a di-, tri- or tetrapeptide can bind DNA directly and selectively modulate gene expression in one target tissue, with each peptide assigned to a specific organ.
Vendors sell them under Latin trade names, which is why the catalog reads as a list of invented words. The tissue assignment behind each name is the useful part:
Several were synthesized to match peptides the group reported in animal tissue extracts, Epitalon from a pineal preparation among them.
This is the question that matters most when comparing prices across the family, and the honest answer is that it varies by compound. Several have a settled sequence: Vilon is the dipeptide Lys-Glu, Vesugen is Lys-Glu-Asp and Cortagen is Ala-Glu-Asp-Pro, and the pages for Epitalon and Pinealon give theirs.
Others do not. Vendor pages attribute more than one sequence to Cartalax, one of them Bronchogen's, and the Cartalax page sets out which one its developers published. Crystagen and Ovagen appear in the literature almost only in their developers' own reviews, which list them as Glu-Asp-Pro and Glu-Asp-Leu and assign Ovagen to the liver and kidney despite a name that suggests the ovary. PeptideScouter carries no CAS number for Cartalax, Crystagen or Ovagen. Where a compound's identity is not settled, a per-milligram price is comparing labels rather than molecules.
Most published work on the family comes from Khavinson's institute and its collaborators, much of it in Russian-language journals. The human data consists of small studies, several of them run with the tissue extracts the peptides were modeled on rather than with the synthetic peptides themselves.
Two compounds here come from unrelated research lines.
FOXO4-DRI is a synthetic senolytic peptide, built to trigger cell death selectively in senescent cells.
Humanin is a peptide encoded in mitochondrial DNA, in the same mitochondrial-derived class as MOTS-c, which is catalogued under Mitochondrial.
NAD+ is a non-peptide coenzyme, and Glutathione is a tripeptide but functions as an antioxidant rather than a signaling bioregulator. Both are catalogued here because they share the longevity-supplement commercial context, and both are worth understanding separately from the rest of the category for a mundane reason: they are sold in much larger milligram quantities than the short peptides, at a small fraction of the per-milligram price, so they dominate this category's price statistics.
Nothing in this category holds an FDA approval for an anti-aging indication. Among the Khavinson peptides in this category, only Epitalon has appeared on FDA's compounding lists or gone before its Pharmacy Compounding Advisory Committee, and its page covers that record. A committee vote is advisory, and the Section 503A bulks list changes only through notice-and-comment rulemaking. In October 2026 HHS issued a policy under which it does not intend to take enforcement action against pharmacies compounding Epitalon under set conditions until a final rule settles its listing, and our post on the HHS policy covers its terms.
They are ultra-short peptide bioregulators, two to four amino acids long, developed by Vladimir Khavinson and the Saint Petersburg Institute of Bioregulation and Gerontology. The group's papers call them cytogens. Each is assigned to a target tissue, which is what the Latin trade names encode. Vilon and Crystagen are the immune and thymic entries. Epitalon, Pinealon and Cortagen are pineal and central nervous system. Vesugen and Cardiogen are vascular and cardiac. Chonluten and Bronchogen are respiratory. Livagen, Pancragen and Ovagen are digestive and metabolic. Testagen and Prostamax are reproductive. Cartalax is the cartilage entry.
Not for all of them, which matters if you are comparing prices per milligram. Vilon, Epitalon, Pinealon, Vesugen and Cortagen each have one settled sequence. Others do not. Cartalax is the tripeptide Ala-Glu-Asp in its developers' patent and reviews, and the tetrapeptide Ala-Glu-Asp-Leu sometimes attributed to it is Bronchogen. Crystagen and Ovagen appear in the literature almost only in their developers' own reviews, which list them as Glu-Asp-Pro and Glu-Asp-Leu. PeptideScouter carries no CAS number for Cartalax, Crystagen or Ovagen.
Neither is a peptide bioregulator in the sense the rest of this category uses. NAD+ is a coenzyme built from nicotinamide and adenine nucleotides. Glutathione is technically a tripeptide, but it functions as a cellular antioxidant and redox buffer rather than as a signaling molecule targeting a tissue. Both are catalogued here because research-peptide vendors sell them from the same catalogs. One practical consequence is that they distort the category's price statistics: both are sold in far larger milligram quantities than the short peptides, at a small fraction of the per-milligram price, so they anchor the low end of any per-milligram comparison across this category.
No. In July 2026 the FDA Pharmacy Compounding Advisory Committee voted to recommend adding Epitalon to the Section 503A bulk drug substances list. The vote is advisory and does not make Epitalon an approved drug or authorize compounding on its own, because the FDA changes the bulks list through notice-and-comment rulemaking and is not bound by the committee's recommendation.
47 vendors tracked by PeptideScouter sell Longevity & Bioregulators peptides, across 364 listings covering 19 compounds.
