Ipamorelin

Also known as: NNC 26-0161

Ipamorelin is a synthetic pentapeptide growth-hormone secretagogue that selectively binds the ghrelin/GHS-R1a receptor.

Research context

Ipamorelin is a synthetic pentapeptide growth-hormone secretagogue that selectively binds the ghrelin/GHS-R1a receptor. Preclinical work characterizes it as inducing GH release without significant effect on cortisol or prolactin, a selectivity feature that has made it a common tool compound in GHS-R pharmacology research.

Storage & stability

Store lyophilized at -20°C.

Purity & testing standards

Each batch of Ipamorelin is analyzed by an independent third-party laboratory. Standard release testing includes reverse-phase HPLC at 220 nm (purity target HPLC ≥99%), electrospray mass spectrometry (identity confirmation), and endotoxin screening. Batch numbers on each vial resolve to a downloadable COA on this site.
