Mechanism of Action

Mk-677 (Ibutamoren) is a growth hormone secretagogue that mimics the action of ghrelin, the "hunger hormone." By binding to ghrelin receptors, it stimulates the release of growth hormone and IGF-1 from the pituitary gland without affecting cortisol levels. This promotes muscle growth, fat metabolism, and potentially other health benefits.
