MK-677 is a hormone secretion compound that stimulates the pituitary gland to increase the production of human growth hormone. Ibutamoren is long-acting, orally-active, selective, and non-peptide agonist of the ghrelin receptor and a growth hormone secretagogue, imitating the growth hormone (GH)-stimulating action of the endogenous hormone ghrelin.
Ibutamoren has been shown to sustain activation of the GH–IGF-1 axis and to increase lean body mass with no change in total fat mass or visceral fat. It is a potential treatment for reduced levels of these hormones, such as in children or elderly adults with growth hormone deficiency, and human studies have shown it to increase both muscle mass and bone mineral density, making it a promising potential therapy for the treatment of frailty in the elderly
MK-677, also known as Ibutamoren or Nutrobal, is commonly referred to as a SARM, a selective androgen receptor modulator, but it is actually a Human Growth Hormone secretagogue, meaning that it stimulates the pituitary gland to secrete HGH. MK-677 has been shown to increase fat-free mass; enhance sleep quality; improve healing of muscle, bone and ligaments; lower LDL cholesterol; improve hair and skin appearance; and improve overall sense of well-being.MK-677 does not cause pituitary sensitization, nor does it suppress the body’s production of Growth Hormone. Because Ibutamoren doesn’t stimulate testosterone, there are no chances of aromatization, or danger to liver, kidney, or prostate.
