Ipamorelin is a synthetic pentapeptide, Aib-His-D-2-Nal-D-Phe-Lys-NH2, and a selective agonist at the growth hormone secretagogue receptor (GHSR). That selectivity is its research interest: preclinical work compares its receptor profile with earlier GHRP compounds such as GHRP-6 and uses it as a reference compound in ghrelin receptor binding assays.
Core Research Peptides supplies it as 10mg of lyophilized powder in a sealed vial under SKU CRP-IPA-10, at 99% purity, alongside the 5mg size. It reconstitutes in bacteriostatic water and stores at -20°C for long term work, 2 to 8°C once reconstituted.
