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. For many groups in aging research, this tetrapeptide enters the workflow because it gives a defined, short sequence tied to pineal and telomere-related readouts, which makes it easy to dose in long studies. Researchers tend to reach for it when they want a low-complexity peptide whose effects can be attributed cleanly, and the short chain keeps synthesis and analysis reproducible. The value often comes down to simplicity: a tetrapeptide is far easier to handle and document than a long multi-domain protein. We supply it with HPLC-verified purity, and the same lot can be reserved for the entire cohort so age-related endpoints stay comparable. Supply of this tetrapeptide is handled with long studies in mind, and each order carries the HPLC purity report and handling notes. We can reserve one lot for the entire cohort and arrange delivery within recommended conditions. Trial and bulk sizes are offered, with the lot data included. 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.
