Leuprolide, also known as Leuprorelin, is a synthetic nonapeptide GnRH agonist with a D-leucine substitution, studied in reproductive and endocrine research. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials. Leuprolide is investigated in research on gonadotropin regulation and reproductive endocrinology, and is commonly applied in cell-based and preclinical studies. The lyophilized form provides good stability and reproducible experimental dosing. Strict quality control is applied to every production batch, and we can supply batch-specific COA documents upon request. Unopened material should be stored sealed at 2-8 degree C in a dry, dark place; for longer storage -20 degree C is advised while avoiding repeated freezing and thawing. We support trial orders and large-volume supply, with OEM and custom private-label options and discreet worldwide shipping available. For research purposes only, not for human or veterinary use.
