Epithalon (Epitalon)

Epithalon (also known as Epitalon or Epithalone) is a synthetic tetrapeptide based on the naturally occurring peptide epithalamin, isolated from the pineal gland. The compound represents the putative active fragment responsible for epithalamin's effects on telomerase activation and has become one of the most researched peptides in the longevity field.

Research has demonstrated Epithalon activates telomerase, the enzyme responsible for maintaining telomere length at chromosome ends. Telomere shortening is a fundamental mechanism of cellular aging, and telomerase activation has been proposed as a strategy for extending cellular lifespan and delaying senescence-associated changes.

In addition to telomerase effects, Epithalon influences pineal gland function, stimulating melatonin synthesis and secretion. This has implications for circadian rhythm regulation, sleep quality, and the broad antioxidant and immunomodulatory functions of melatonin.

Animal studies, particularly in rodent models, have shown Epithalon administration extends maximum lifespan and delays the onset of age-related pathologies. The compound has demonstrated effects on tumor suppression, immune function restoration, and normalization of age-related hormonal changes. These findings have positioned Epithalon as a leading candidate for anti-aging research.
