Evidence Tier: Preclinical — Epithalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide based on epithalamin, a polypeptide extract from the pineal gland. Studied for telomerase activation and lifespan extension in animal models.
Overview
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) designed as a synthetic version of epithalamin, a polypeptide produced by the pineal gland. It was developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology in Russia.
Mechanism of Action
- Telomerase Activation: Induces telomerase activity in human somatic cells, potentially lengthening telomeres
- Pineal Gland Regulation: Stimulates melatonin production from the pineal gland
- Antioxidant Gene Expression: Upregulates endogenous antioxidant enzyme expression
Key Research Findings
- Animal studies report 12-24% lifespan enhancement in rodent models (Anisimov et al.)
- Improved visual function reported in retinitis pigmentosa patients in small Russian clinical studies
- Telomerase activation demonstrated in human fetal fibroblast cell cultures
Critical caveat: No randomized, double-blind, placebo-controlled trials have been conducted in Western institutions. All human data comes from Russian clinical studies with limited peer review in English-language journals.
Regulatory Status
FDA: Scheduled for PCAC evaluation July 23-24, 2026.
