MK-677
Orally active ghrelin mimetic and GH secretagogue
Ibutamoren Mesylate (MK-677)
MK-677 (Ibutamoren) is an orally active, non-peptide ghrelin receptor agonist and growth hormone secretagogue. By mimicking the action of ghrelin at the GHS-R1a receptor, it stimulates pulsatile growth hormone release and elevates IGF-1 without suppressing endogenous production. Its long half-life and oral bioavailability make it a widely used reference compound in studies of the GH/IGF-1 axis, appetite signaling, sleep architecture, and body composition.
