Maximum Performance Labs | MK677

Looking to enhance your recovery and increase your body's natural growth hormone production. MK677 is a new drug in the bodybuilding world. Its benefits have not been officially confirmed yet, but most people who take it, swear by it. Even though it’s mainly associated with bodybuilders, people with disabilities and hormone deficiencies benefit from it as well.

Many people often mistake Ibutamoren for a SARM, which it is not. It is not a typical growth stimulator either.

Ibutamoren (MK677) is a potent, long-acting, orally-active, selective, and non-peptide agonist of the ghrelin receptor and a growth hormone secretagogue, mimicking the growth hormone-stimulating action of the endogenous hormone ghrelin.
Growth hormone is needed for the body to perform optimally. It plays a crucial role in the development of muscles and tissue.
