Ipamorelin is a pentapeptide which means it is made up of a chain of 5 amino acids. It’s formally known as a growth hormone secretagogue – a compound that is not a growth hormone itself but promotes and triggers the production of growth hormone in the human pituitary gland. In the case of Ipamorelin, it also acts as a ghrelin/growth hormone secretagogue receptor agonist.  In less science-heavy terms, the action of Ipamorelin mimics the action of the natural hormone ghrelin in the body.  Through that process, it triggers the release of human growth hormone from the pituitary gland.  Normally, hormones may trigger the release of multiple other chemicals or hormones which causes side effects, but Ipamorelin is more specific in its action and triggers only growth hormone release.
