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. Stock is maintained for the most requested products to shorten lead times, and made-to-order items are typically produced within days. We support bank transfer, major digital payments and verified trade channels, with order updates provided at every shipping stage. Protective secondary packaging is standard for international parcels.
