Ipamorelin is a synthetic pentapeptide and one of the most selective growth hormone secretagogues studied to date. It acts as a ghrelin mimetic, binding to the growth hormone secretagogue receptor (GHS-R) to stimulate GH release without significantly affecting cortisol, prolactin, or ACTH levels.
Ipamorelin is a synthetic pentapeptide with the sequence Aib-His-D-2Nal-D-Phe-Lys-NH2. Developed by Novo Nordisk, it is classified as a growth hormone secretagogue (GHS) and ghrelin receptor agonist. Unlike other GHS compounds such as GHRP-6 or GHRP-2, Ipamorelin is highly selective for growth hormone release and does not significantly stimulate the secretion of cortisol, prolactin, or adrenocorticotropic hormone (ACTH) at physiologically relevant concentrations. This selectivity makes it a valuable research tool for studying the GH/IGF-1 axis in isolation, without confounding effects from other pituitary hormones.

One (1) vial of Ipamorelin lyophilized powder (5mg per vial), Certificate of Analysis (COA).
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue that selectively targets the ghrelin receptor (GHS-R1a). It is used in in-vitro GHS-R1a binding assays and calcium mobilization/cAMP signaling studies with high selectivity and minimal off-target receptor activation.
