Epitalon

Epitalon (also spelled Epithalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from epithalamin, a peptide complex isolated from the pineal gland. It was developed by Russian researcher Vladimir Khavinson and is one of the most-studied 'bioregulator' peptides.

Epitalon is the longevity-research peptide everyone brings up when telomeres come up. Russian studies have followed it for decades for circadian rhythm, melatonin output, and cellular aging endpoints.

Research suggests Epitalon activates telomerase in somatic cells, supporting telomere elongation and replicative capacity. It also appears to normalize pineal melatonin secretion and may influence circadian gene expression. The exact receptor mechanism remains an open research question.

A staple of longevity, biohacker, and Khavinson-bioregulator communities. Common protocol discussion: short 10–20 day cycles, often 1–2x per year. Debate centers on the gap between strong Russian literature and limited Western replication.

“The telomere peptide.”

Often stacked with other Khavinson bioregulators (Thymalin, Pinealon) in longevity research. Sometimes paired with NAD+ precursors and senolytics.

Epitalon is a synthetic pineal-derived tetrapeptide studied for telomerase activation, melatonin normalization, and longevity research.
