Epithalon

Epithalon is a synthetic four-amino-acid peptide (Ala-Glu-Asp-Gly) developed by Russian scientists based on a natural extract from the pineal gland. It's one of the most studied "anti-aging" peptides, with over 25 years of research behind it. **The big claim: Telomerase activation** Telomeres are the protective caps on your chromosomes — like the plastic tips on shoelaces. Every time your cells divide, these caps get shorter. When they get too short, cells stop dividing and become "senescent" (old). Epithalon may activate telomerase, the enzyme that rebuilds these caps. **What the research shows:** • Activates telomerase in human cells (in laboratory studies) • Increases melatonin production from the pineal gland • Shows antioxidant and neuroprotective properties • Animal studies suggest improved lifespan and healthspan • May help normalize sleep patterns and circadian rhythms **Important context:** Most research comes from Russian laboratories, and large-scale human clinical trials meeting Western standards are lacking. While the science behind telomerase activation is compelling, more research is needed to confirm benefits in humans. **How it's used:** Typically injected subcutaneously in cycles, often before bed to align with natural melatonin production. --- **Sources:** Anisimov VN, et al.

Essentially all human and mechanistic data come from the Khavinson group in Russia, with few independent replications. No large, multicenter human trials exist, and claims of telomere elongation in vivo and lifespan extension in humans remain unproven. There is no regulatory approval outside Russia.

Epithalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on a pineal peptide (epithalamin). In Russian practice it is given by subcutaneous or intramuscular injection in short courses. Pharmacokinetic data (half-life, bioavailability) are not well characterized in accessible peer-reviewed literature.
