Full-length corticotropin (1-39) · HPA-axis research peptide
Overview
ACTH(1-39), also known as corticotropin, is the full-length 39-amino-acid endogenous peptide hormone produced by cleavage of proopiomelanocortin (POMC) in the anterior pituitary. It is the central effector of the hypothalamic-pituitary-adrenal (HPA) axis, binding melanocortin receptor 2 (MC2-R) to stimulate adrenal cortical synthesis and secretion of glucocorticoids such as cortisol. Vialdyne releases ACTH (1-39) 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.
