MK-677, also known as Ibutamoren, is a powerful growth hormone secretagogue that stimulates the release of growth hormone (GH) and IGF-1 without the need for injections. Unlike SARMs, MK-677 does not bind to androgen receptors but instead mimics ghrelin — the “hunger hormone” — to activate the brain’s GH release pathway.

Used to support lean muscle growth, fat loss, recovery, and even improved sleep and skin quality, MK-677 is a versatile compound with widespread appeal. Its ability to elevate natural GH levels makes it a preferred option for those looking to enhance recovery, slow aging, or break through training plateaus — all while maintaining a natural testosterone balance.
