Epithalon

Epitalon (Epithalon, AEDG) is a synthetic tetrapeptide composed of four amino acids (Ala–Glu–Asp–Gly) and is based on a peptide originally isolated from the pineal gland. It has been studied in research settings for its role in cellular regulatory pathways, including mechanisms related to telomerase activity, melatonin signaling, and gene expression processes.
