Hexarelin is a hexapeptide secretagogue carrying a D-amino-acid residue that improves resistance to enzymatic breakdown, prolonging GH-release activity in experimental settings. Beyond the GH axis, its interaction with CD36 opens additional research directions in cardiovascular biology. This product is a white lyophilized powder in a sealed vial with purity confirmed by HPLC, and bulk or trial quantities are both accommodated. The peptide is synthesized under controlled conditions and lyophilized to a stable powder form that is easy to transport and store. Our quality-management approach covers raw materials, production and final release testing, providing researchers with consistent material for reproducible experiments.
