Also known as Ibutamoren or Nutrobal, MK-677 is a compound that acts as a neuropeptide in the central nervous system. It mimics the action of the ghrelin, therefore allowing your body to produce more IGF-1 and GH without affecting your cortisol levels.


Its half-life is 24 hours, that is why dosage is typically taken once daily. When taken on its own, MK-677 has the potential to increase HGH levels without impacting other hormones. It is popular amongst bodybuilders during their time off-cycle as a safe and effective way to maintain muscle mass and stay lean.


MK-677 has no known adverse side effects, aside from increasing the appetite. It also impacts glucose levels. If diabetic, it's important to take the necessary precautions while on the cycle such as monitoring often and eating food accordingly.
