Build muscle, sleep deeper, recover faster—all in a pill.
Also known as: Ibutamoren; Oratrope
Overview
MK-677 is an orally active compound that mimics ghrelin and stimulates your body to produce more growth hormone and IGF-1. Unlike injecting synthetic HGH, this triggers your natural pulsatile GH release. Users report better sleep, faster recovery, increased muscle mass, and improved body composition. It's one of the most popular compounds for anti-aging and bodybuilding.
