Ibutamoren is frequently discussed on online forums for its anabolic muscle-building properties. It is available over the counter and used by those wishing to increase their growth hormone levels. However, clinical studies of this compound are relatively few. In the text below, we will highlight what is known about ibutamoren so far.

Ibutamoren (MK-677) promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1) (R, R). It 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.

BENEFITS

Ibutamoren (MK-677) was originally formulated to keep health problems like osteoporosis, obesity and muscle wasting, but has been seen to promote an increase in lean body mass as well as a boost Increased Fat Oxidation (fat loss).
