What is Epitalon and what does research show?

Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed from pineal-gland extract research. It is studied in preclinical models for telomerase activity, circadian-rhythm and pineal-axis signaling, and cellular-senescence pathways.

Epitalon (also spelled Epithalon) is a short synthetic tetrapeptide — Ala-Glu-Asp-Gly — derived from research on a polypeptide extract of the bovine pineal gland called Epithalamin.

Research focus:

  • Telomerase activity — Epitalon is one of the most-studied peptides in telomere-biology research.
  • Pineal and circadian-rhythm signaling.
  • Cellular senescence markers in preclinical and in-vitro models.

Most of the published literature on Epitalon comes from Russian gerontology research. As with all research peptides, Epitalon is supplied by ADAM Molecular Research strictly for in-vitro and preclinical laboratory investigation. No human therapeutic claims are made.
