Epitalon

Overview

Epitalon (also spelled Epithalon) is a synthetic tetrapeptide — just four amino acids, Ala-Glu-Asp-Gly. It was developed as a defined synthetic version of epithalamin, a peptide preparation from the pineal gland studied extensively by Russian gerontology researchers as part of a broader program on “peptide bioregulators.”

It is one of the more speculative entries in the longevity category: widely discussed, but supported mainly by a relatively narrow research literature.

Mechanism of action

The proposed mechanisms, drawn largely from cell-culture and animal work, include:

• Telomerase activation — some studies report increased telomerase activity and telomere lengthening in cultured cells, which is the basis of its anti-ageing reputation.
• Pineal and circadian regulation — effects on melatonin rhythm and the body’s internal clock, reflecting its pineal origin.
• Antioxidant and gene-expression effects in various models.

These mechanisms are not well established in humans, and the telomerase claim in particular should be read cautiously.

Common research uses

• Ageing and telomere-biology research
• Circadian rhythm and pineal-function studies
• General “peptide bioregulator” investigations in the gerontology literature
