Epitalon, also known as Epithalon, is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly that originates from the pineal peptide epithalamin, studied in aging and chronobiology research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Epitalon is investigated in research on telomere maintenance, circadian rhythm regulation, pineal function and aging-related mechanisms, and is commonly applied in cell-based and preclinical studies. The freeze-dried form ensures high stability and easy reconstitution for reproducible experimental dosing. All lots pass strict quality verification and lot-specific certificates can be provided on request. Keep unopened material sealed at 2-8 degree C away from light and moisture; store at -20 degree C for longer periods and avoid repeated freezing. We accept small trial and large bulk orders and provide OEM, private-label and neutral discreet-packaging services with global delivery. Laboratory research use only.
