Epitalon
A four-amino-acid peptide studied primarily in Russian and Eastern European research for longevity, sleep, and antioxidant effects.
In plain English
Epitalon (also called epithalon) is a tetrapeptide (Ala-Glu-Asp-Gly) developed in the 1980s by Vladimir Khavinson and colleagues in St. Petersburg, Russia. It is a synthetic analog of a polypeptide extract from the pineal gland (epithalamin). Most published work is in Russian-language journals or small Russian-led trials, with claims around telomere maintenance, melatonin secretion, sleep, and life-span extension. Outside that body of research, mainstream Western RCT evidence is essentially absent. Epitalon is not FDA-approved.
What it is
Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on a polypeptide fraction of the pineal gland.
Mechanism (summary)
Proposed mechanisms include activation of telomerase, modulation of pineal melatonin secretion, and influence on circadian and neuroendocrine signaling. The molecular basis is not well-characterized in mainstream literature.
Why people research it
- Telomere length and cellular aging
- Sleep and melatonin secretion
- Antioxidant signaling
- Age-related decline in pineal function
Human evidence
Small, mostly Russian-language clinical reports in older adults describe improvements in sleep architecture, melatonin patterns, and select clinical endpoints. Mainstream peer-reviewed RCTs in English-language journals are essentially absent.
Animal / lab evidence
Rodent studies from the Khavinson group describe extended median life span, reduced spontaneous tumor incidence, and antioxidant effects.

History
