Ibutamoren [mk-677] is a substance that is associated with more discussions on online forums than actual clinical research. However, the research so far does support several benefits of ibutamoren, associated with its ability to increase growth hormone and IGF-1 levels.
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) (R, R).
Ibutamoren increases growth hormone levels, by mimicking the action of the hormone ghrelin (R), and binding to one of the ghrelin receptors (GHSR) in the brain (R). Activated GHSR stimulates growth hormone release from the brain.
A great thing about ibutamoren is that it increases growth hormone levels with little or no increase in other hormones, such as cortisol (R, R). Cortisol suppresses the immune system, reduces wound healing, and impairs learning and memory, and it’s usually not good to have this hormone elevated.
