About Ipamorelin
- Molecular weight
- 711.9 g/mol
- CAS number
- 170851-70-4
Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH₂) that acts as a selective agonist of the growth hormone secretagogue receptor (GHS-R1a, the ghrelin receptor). In preclinical cell and animal studies it stimulated pituitary growth-hormone release with reported selectivity relative to other pituitary hormones. It is used as a reference tool compound in laboratory research on GHS-R signalling.
