Epithalon is a synthetic tetrapeptide derived from epithalamin research and composed of the amino acid sequence Ala-Glu-Asp-Gly. It has been studied extensively in longevity and cellular aging research for its relationship to telomerase activity, circadian regulation, oxidative stress response, and age-associated gene-expression pathways across experimental models. Its unusually short four-amino-acid structure places it among the smallest peptide bioregulators explored within longevity-focused signaling research. Lyophilized powder, 3mL vial. Sold at 10mg per vial. For research use only.
