Longevity

Epitalon

A synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed from research on the pineal peptide epithalamin. Promoted for longevity and telomere/telomerase effects, primarily on the basis of Russian rodent and cell studies; rigorous independent human evidence is lacking.

Limitations · Who should NOT use this

The headline telomerase and lifespan claims rest largely on studies from the originating Russian research group and have not been robustly replicated by independent labs or in controlled human trials. No rigorous human efficacy or long-term safety data. Telomerase activation, if real, carries theoretical oncological considerations that are not characterized. Gray-market sourcing with no oversight. Claims should be held at low confidence.

Regulatory notes

Not FDA-approved. Derived from Russian peptide-bioregulator research; not approved or independently validated in Western regulatory contexts. Available through research-chemical channels only. No standardized clinical dosing. On July 23–24, 2026, the FDA Pharmacy Compounding Advisory Committee (PCAC) voted to recommend adding it to the 503A bulks list. The vote is non-binding: until FDA completes rulemaking, it cannot be lawfully compounded in the US.

Verify what's actually in your Epitalon vial

Gray-market peptide vials vary widely on identity, purity, and labeled concentration. Finnrick is an independent testing platform that ships consumer-submitted samples to commercial labs and publishes every result in a free public database. Vendors cannot pay for placement or to suppress a result. We don't operate Finnrick — we link to it because post-purchase verification is the right complement to pre-purchase clinical evidence.
