Ibutamoren (also known as ibutamoren mesylate or MK-677), promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1).Ibutamoren increases levels, by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors in the brain. Activated ghrelin receptors stimulate growth hormone release from the brain.
Benefits of increased GH and IGF-1 include:
- Increased bone turnover and eventually bone density
- Improved sleep quality and REM (rapid eye movement) sleep duration.
- Reduced Muscle Wasting
- Increased muscle mass
- Reduced fat mass
- Possible healing of tendons, joints, and ligaments
