Epithalon

Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) based on the natural peptide epithalamin, which is produced by the pineal gland. It was developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, who has spent over 35 years researching peptide bioregulators for anti-aging. Epithalon's primary mechanism of action is the activation of telomerase — the enzyme that adds telomeric repeats to the ends of chromosomes.

Telomeres are protective caps on chromosomes that shorten with each cell division, and their progressive shortening is one of the hallmarks of biological aging. When telomeres become critically short, cells enter senescence or apoptosis. By activating telomerase, Epithalon can lengthen telomeres and potentially extend the replicative lifespan of cells. In a landmark study, Epithalon treatment increased the lifespan of elderly mice by 13.3%.

The peptide also stimulates melatonin production from the pineal gland, improving circadian rhythm regulation and sleep quality. Additionally, it has demonstrated antioxidant properties and the ability to normalize anterior pituitary function, restoring more youthful hormone profiles.
