MK-677 (Ibutamoren)
25 mg/mL (30mL)
>99% HPLC
MK-677 (Ibutamoren) is a potent, orally active growth hormone secretagogue that mimics the signaling of ghrelin at the GHS-R1a receptor. It produces sustained increases in GH and IGF-1 levels without affecting cortisol.

How it Works
In Plain Language
Ghrelin is the 'hunger hormone' that also tells your pituitary gland to release growth hormone. MK-677 mimics ghrelin's effect on GH release (but orally, without injections). It's like pressing the natural GH release button repeatedly throughout the day, leading to higher GH and IGF-1 levels.
