Ipamorelin

Description

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 weight of 711.86 g/mol and the formula C38H49N9O5 (CAS 170851-70-4). First described in the mid-1990s, it is classified as a growth hormone secretagogue (GHS), a category of compounds designed to interact with the ghrelin/GHS receptor. Its structure includes two non-standard amino acids — aminoisobutyric acid (Aib) and D-2-naphthylalanine (D-2-Nal) — which set it apart from naturally occurring peptides. Ipamorelin appears as a white to off-white lyophilized powder that dissolves readily in water and requires refrigerated storage. This product is strictly for research purposes only.
