About MK 677: Ghrelin is an endogenous ligand for the growth hormone (GH) secretagogue receptor (GHSR).1 Ibutamoren is an orally-active, non-peptidic agonist of GHSR (Kd = 0.4 nM) and, as a result, is a GH secretagogue.2,3 It elevates GH in dogs after oral doses as low as 0.125 mg/kg, without significantly changing plasma levels of aldosterone, luteinizing hormone, thyroxine, or prolactin.4
