Epitalon
Also known as: Epithalon, Epithalamin (related extract), AEDG, Ala-Glu-Asp-Gly
A synthetic four-amino-acid peptide proposed by Russian researchers to influence pineal function and aging, with an evidence base concentrated almost entirely in one research network.

Key Takeaways
- ›Epitalon is a synthetic tetrapeptide developed in Russia and promoted for anti-aging and telomere support.
- ›Nearly all positive findings come from a single research network, with essentially no independent replication.
- ›The proposed telomerase-activation mechanism conflicts with mainstream telomere biology.
- ›It is not FDA-approved, and long-term safety is not independently established.
- ›Longevity claims far exceed the evidence. Speak with a licensed healthcare professional.
What It Is
Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by the Russian researcher Vladimir Khavinson and colleagues at the Saint Petersburg Institute of Bioregulation and Gerontology. The peptide was designed as a synthetic counterpart to a pineal-gland extract known as epithalamin, which itself was used in Soviet-era clinical research as a proposed regulator of pineal and reproductive function.
Mechanistically, epitalon has been proposed to influence pineal melatonin production, telomerase activity, and broader gene-expression patterns relevant to aging. The Khavinson group has published a substantial body of work on a family of short peptide bioregulators, of which epitalon is one of the most discussed. The proposed framework — that short oligopeptides function as 'bioregulators' modulating tissue-specific gene expression — is a distinctive theoretical framing largely associated with this research tradition.
