Synthetic GnRH decapeptide · HPG-axis secretagogue
Overview
Gonadorelin Acetate is the synthetic acetate salt form of native hypothalamic gonadotropin-releasing hormone (GnRH/LHRH), a linear decapeptide (10 amino acids) with C-terminal amidation. Different salt forms were previously FDA-approved for human use under the brand names Lutrepulse (gonadorelin acetate, pulsatile pump device, for ovulation induction and treatment of hypothalamic amenorrhea/hypogonadotropic hypogonadism; discontinued in the US) and Factrel (gonadorelin hydrochloride, used for human pituitary function diagnostics; the human formulation is discontinued, though a separate FDA-approved veterinary pro… Vialdyne releases Gonadorelin Acetate as a lyophilized peptide against a ≥98% HPLC main-peak specification, supplied with a batch-specific Certificate of Analysis covering RP-HPLC purity, mass-spec identity, appearance, and water content. Lots are released only after the COA is on file.
Applications & buyer fit
GH-axis peptides ship to two main buyer types: compounding pharmacies dispensing under physician supervision, and research labs studying somatotropic-axis pharmacology. Pharmacies typically want sterile-filled vials with the full release packet (sterility, endotoxin, CCI); labs typically want loose-format lyophilized powder with sequence verification. Blends (the CJC-1295 / Ipamorelin combination is the canonical example) are usually co-lyophilized rather than solution-mixed for potency stability.
