Quick Summary
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) modelled on a bovine pineal extract, studied almost entirely by one Russian research group and in cell culture. Available from 57 vendors, priced from $20.00 to $809.91.
Research: The 1.6 to 1.8-fold lower mortality usually attributed to epithalon is not a finding about epithalon. Khavinson and Morozov, Neuroendocrinol Lett 2003;24(3/4):233-240, report it for EPITHALAMIN, a bovine pineal extract, not for the synthetic tetrapeptide sold here. The 266 participants were the total across all arms including placebo, leaving roughly 75 in the relevant group, and dosing ran only in the first 2 to 3 years of a 6 to 8 year observation. The telomerase result is cell culture only (Khavinson, Bondarev and Butyugov, Bull Exp Biol Med 2003;135(6):590-592, in telomerase-negative human fetal fibroblasts), and the 2025 follow-up work (Al-Dulaimi et al, Biogerontology, September 2025) is also cell culture and reports alternative-lengthening-of-telomeres activity in breast cancer lines.
Side effects: The Alzheimer's Drug Discovery Foundation states that clinical studies on epithalon have not been conducted, so no human adverse event data exists
Research compoundStudied almost entirely by the group that developed it, and no other group has confirmed its results. Not approved for human use.
