Thymalin Alternatives

Epithalon (also spelled Epitalon) is a synthetic four-amino-acid peptide, Ala-Glu-Asp-Gly (AEDG), modeled on a natural pineal gland extract. It came out of decades of Russian gerontology research led by Vladimir Khavinson and is marketed as an anti-aging compound that supposedly switches telomerase back on. It has no approval from the FDA, EMA, or other Western regulators, and the human evidence is thin.

Pinealon is a synthetic tripeptide, Glu-Asp-Arg (the EDR peptide), from the Russian peptide-bioregulator family designed to mimic short signaling peptides found in brain tissue. It is studied as a neuroprotective and antioxidant compound, with researchers proposing it protects neurons from oxidative stress and supports cognition. Be clear-eyed about the evidence: it is essentially all cell-culture and animal work from a small set of related labs, with no human clinical trials and no regulatory approval.

Vilon is a synthetic dipeptide, Lys-Glu (lysine-glutamic acid), one of the short peptide bioregulators developed by Vladimir Khavinson's group at the St. Petersburg Institute of Bioregulation and Gerontology in Russia. It is marketed in the anti-aging and immune-support space as a thymus-related bioregulator, but the real evidence base is almost entirely Russian animal studies. There are no registered Western randomized human clinical trials, so any human claims should be read with heavy skepticism.

Cartalax is a synthetic tripeptide (Ala-Glu-Asp, or AED) from the Khavinson family of short peptide bioregulators, studied as a cartilage and connective-tissue regulator. It is a research compound, not an approved drug, and no registered human clinical trials exist.

Livagen is a synthetic tetrapeptide (Lys-Glu-Asp-Ala, or KEDA) from the family of short "peptide bioregulators" developed by Vladimir Khavinson's group in St. Petersburg, marketed in connection with liver and immune function. The proposed appeal is epigenetic: it has been reported to loosen tightly packed chromatin in aged cells, supposedly switching age-silenced genes back on. Evidence is limited to small laboratory and cell studies, mostly from one research group, with no clinical trials, so claims should be read with heavy skepticism.

Ovagen is a synthetic ultra-short peptide, marketed as the tripeptide Glu-Asp-Leu (EDL), and grouped with the Khavinson-style "peptide bioregulators" promoted for liver and gastrointestinal support. Like its cousins in that family, it is claimed to act at the gene-expression level in a tissue-specific way. The honest picture: there is very little verifiable scientific data on Ovagen specifically, no clinical trials, and most of what is written about it comes from vendors rather than peer-reviewed research.

Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro, AEDP) from Vladimir Khavinson's Russian peptide bioregulator program, designed as the defined-sequence stand-in for Cortexin, an older cattle brain cortex extract used in Russian neurology. It is studied mostly for nerve repair, brain function and aging, and it is not approved by the FDA or EMA. Real evidence is limited to animal experiments and Russian-institute work, with no Western randomized human trials.

Vesugen is a synthetic tripeptide (Lys-Glu-Asp, or KED) from the Khavinson family of short peptide bioregulators, studied for vascular and neuroprotective effects. It is a research compound, not an approved drug, with no registered human clinical trials.
