MK-677

MK-677, also known as Ibutamoren Nutrobal, is not a steroid, and it's not actually a SARM (Selective Androgen Receptor Modulator). MK-677 is what is known as a selective agonist. Agonists are chemical substances that can bind to receptors in the body and stimulate them to produce natural physiological responses. MK-677 works on the ghrelin receptor and receptors responsible for the production and secretion of growth hormone. Although often marketed in the black market as a SARM, MK-677 is not actually a SARM. This medication is being researched for the treatment of growth hormone deficiency and has the potential to increase muscle mass, metabolism, energy, fat burning, and bone strength. Remember that the use of MK-677 should always be consulted with a healthcare professional.
