Selective growth-hormone secretagogue studied in GH-release research.
MK-677 is an oral, non-peptide ghrelin-receptor agonist and growth-hormone secretagogue. Research examines sustained changes in GH and IGF-1, along with appetite, sleep, and body-composition measures.
MK-677 is orally bioavailable and is studied for sustained GH and IGF-1 changes. Research also tracks appetite, drowsiness, glucose markers, and other longer-term effects.
