Description
MK-677 (ibutamoren) is a non-peptide, orally active agonist of the ghrelin receptor — a small molecule doing a peptide’s job, which is its principal research significance.
Long-duration studies use it to model sustained GH and IGF-1 elevation, with published human research on body composition, sleep architecture and bone turnover from its clinical-development era.
