Epithalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide analogue of the natural pineal gland peptide Epitalon, renowned for its telomerase-activating and potential life-extending properties in research models. This four-amino-acid peptide has been extensively studied for its ability to modulate epigenetic regulation, stimulate telomerase activity, and influence aging-related biomarkers. Our research-grade Epithalon is synthesized with pharmaceutical purity for precise investigation of cellular aging mechanisms and longevity pathways.
