MK-677

MK-677 (ibutamoren) is an oral, non-peptide secretagogue that stimulates growth hormone release by mimicking ghrelin.

What it is

MK-677 binds to the ghrelin receptor (GHSR) and increases pulsatile release of growth hormone and IGF-1 without significantly affecting cortisol levels. The compound has been studied in clinical trials for its role in counteracting muscle wasting and supporting bone density. For research use only. Not for human use.
