Gonadorelin is the synthetic decapeptide form of gonadotropin-releasing hormone (GnRH), the hypothalamic neurohormone that controls pituitary LH and FSH secretion. As the native releasing factor it serves as a reference standard in reproductive endocrinology and pituitary-function testing. The peptide is supplied as a white lyophilized powder at >=99% HPLC purity in a sealed vial. Batch records and flexible supply arrangements are provided for research institutions. For customers outside China, we prepare all export documents, including commercial invoice, packing list and certificate of origin as needed. Our logistics partners cover North America, Europe, Latin America and Asia with tracked services, and we update buyers on the shipment progress until delivery is confirmed.
