Epitalon is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on the pineal gland peptide epithalamin, investigated for its reported influence on telomere maintenance, circadian rhythm and age-related processes in experimental biology. Its short sequence and defined structure make it convenient for cell-based aging research. The peptide is supplied as a white lyophilized powder at >=99% HPLC purity in a sealed vial. Complete quality documentation and flexible order sizes are provided for research teams. All items are dispatched in plain, discreet packaging to protect buyer privacy, and high-value orders may be split into multiple parcels for customs safety. Delivery times to most destinations range from a few days to two weeks depending on the region and courier selected.
