Overview
Ipamorelin is a synthetic pentapeptide — a chain of five amino acids — with the sequence Aib-His-D-2-Nal-D-Phe-Lys. It has a molecular formula of C38H49N9O5, a molecular weight of 711.86 g/mol, and a CAS number of 170851-70-4. Ipamorelin was first described in the mid-1990s and belongs to the class of compounds known as growth hormone secretagogues (GHS) — molecules that interact with the ghrelin/GHS receptor.
Structurally, Ipamorelin is notable for containing two non-standard amino acids: aminoisobutyric acid (Aib) at the N-terminus and D-2-naphthylalanine (D-2-Nal) in the third position. These modifications distinguish it from natural peptides and contribute to its stability. In its research-grade form, it appears as a white to off-white lyophilized powder that dissolves readily in water.
