Ibutamoren (MK-677)

Ibutamoren (MK-677) is an orally active growth hormone secretagogue that works as a ghrelin receptor agonist, binding to the same receptors targeted by the hunger hormone ghrelin. This receptor activation stimulates the pituitary gland to increase pulsatile growth hormone release, along with a corresponding rise in IGF-1. Because it is orally bioavailable and long-acting, ibutamoren is designed to provide sustained ghrelin receptor stimulation throughout the day, distinguishing it from short-acting injectable secretagogues. EdgeRx offers ibutamoren through a clinician-supervised protocol, prescribed by licensed physicians for eligible patients interested in supporting sleep quality, recovery, and body composition pathways.
