Ibutamoren (also known as ibutamoren mesylate or MK-677), promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1.
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.
GHSR is found in brain regions that control appetite, pleasure, mood, biological rhythms, memory, and cognition (R). Therefore, we can expect that ibutamoren may also affect these functions. However, so far, clinical studies describe only the effects ibutamoren has on appetite – and as expected, like ghrelin, ibutamoren increases it.
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.
