Description: Epitalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide developed in the context of pineal peptide research associated with epithalamin preparations. In research settings, Epitalon is used to investigate cellular aging mechanisms, circadian/pineal-regulation biology, and telomerase-associated pathways. Experimental cell-based studies have reported effects on telomerase activity and telomere-related endpoints, supporting continued investigation of age-related cellular processes.
