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. The tetrapeptide is frequently included in aging-focused protocols where pineal function, circadian output and cellular maintenance markers are evaluated over extended time courses. Its minimal sequence supports straightforward synthesis and quality control, and investigators value the reproducible handling of the lyophilized material. The product is supplied with purity documentation and flexible pack options, making it convenient for laboratories running longitudinal studies in gerontology and chronobiology. Aging-focused programs frequently run extended dosing schedules, so investigators value a peptide that reconstitutes cleanly and remains stable under standard refrigeration between injections. The tetrapeptide is often combined with other bioregulator peptides, and our team can supply matched sets with consistent documentation to simplify multi-arm designs. Each shipment includes purity data and handling guidance, and we accommodate requests for specific pack sizes, labeling or documentation formats. For laboratories planning longitudinal studies, our stable supply and responsive communication make ordering straightforward from the first inquiry to final delivery. We are a professional peptide supplier with in-house quality control, offering both small trial packs and bulk quantities at factory-direct prices. Every order is packed carefully and dispatched with tracking, and our team provides responsive after-sales support for research customers worldwide.
