Ipamorelin is a short peptide sequence capable of binding to the ghrelin/growth hormone secretagogue receptor. It is one of the most selective growth hormone (GH) secretagogues known and has been shown in laboratory studies to have no effect on ACTH, prolactin, follicle-stimulating hormone, luteinizing hormone, thyroid-stimulating hormone, or cortisol release [1]. Given its high level of specificity, ipamorelin has been of interest in research both as a therapeutic in and of itself as well as a model peptide for understanding how selectivity in GH receptor binding is achieved. Its presence plays a key role in the overall growth and repair of musculoskeletal tissue.
