MK-677 Peptide, also known as Ibutamoren, promotes the secretion of growth hormone and increases insulin-like growth factor 1 (IGF-1). It increases growth hormone levels by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors in the brain. MK-677 may be used to increase lean muscle mass, reduce muscle wasting, improve bone density, increase appetite, boost exercise endurance, enhance brain and cardiac health, and improve sleep quality. It may also be used for its anti-aging properties and to promote longevity.
