Is ibutamoren the same as MK-677?

Yes. Ibutamoren is the nonproprietary name for MK-677, the same oral ghrelin-receptor agonist this site's profile lists as Ibutamoren and MK-0677. It is a small molecule, molecular weight 624.8 daltons, not a peptide. It is not FDA approved. The two-year older-adult trial and the stopped hip-fracture trial are the human record on that page. The names are aliases of one molecule, not two drugs. Full record at /compounds/mk-677.
