Ibutamoren mesylate (formerly also known as MK-677, MK-0667, and L-163,191) is a novel, non-peptide, potent, long-acting, orally-active, and selective agonist of the ghrelin receptor and a growth hormone secretagogue (GHSR), mimicking the growth hormone (GH)-stimulating action of the endogenous hormone ghrelin.
