Cetrorelix is a synthetic decapeptide GnRH antagonist that blocks the GnRH receptor, studied in reproductive and endocrine research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Cetrorelix is investigated in research on gonadotropin suppression and reproductive endocrinology, and is commonly applied in cell-based and preclinical studies. The lyophilized format ensures stable reconstitution and consistent experimental dosing. Each batch is manufactured under controlled quality systems and batch-specific certificates of analysis are obtainable on request. Store the sealed vial at 2-8 degree C away from direct light and humidity; for extended storage keep at -20 degree C and minimize freeze-thaw cycles. Small sample orders and bulk quantities are both welcomed, and we provide OEM, private-label and secure neutral-packaging services for global delivery. Laboratory research use only.
