Ipamorelin peptide is comprised of five amino acids (pentapeptide) and is formally known as a ‘growth hormone secretagogue’. Ipamorelin peptide appears to act via ghrelin receptor binding, though its mechanism of action is still under investigation by researchers. It is considered a growth hormone secretagogue (GHS-R) with potential in regulating energy and weight. Ipamorelin peptide is a synthetic peptide, with specific potential similar to growth hormones (HGH). After conducting several research studies and laboratory reviews, Ipamorelin was identified as a pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) with the potential to trigger the pituitary gland and stimulate the release of growth hormones.
