What Is Ipamorelin?
Ipamorelin is a synthetic pentapeptide growth hormone secretagogue with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH2, where Aib represents alpha-aminoisobutyric acid and D-2-Nal represents D-2-naphthylalanine. Developed by Novo Nordisk in the late 1990s, Ipamorelin emerged from systematic structure-activity relationship studies aimed at creating a growth hormone releasing peptide (GHRP) with maximum selectivity for growth hormone release and minimal effects on other pituitary hormones. The result is one of the most selective GH secretagogues identified,...
Evidence Summary
Ipamorelin is a research compound with promising biological signals but limited human validation. Most claims exceed current clinical evidence.
