What Is Ibutamoren???
MK-677 promotes the secretion of the growth hormone (GH) and increases insulin-like growth factor 1 (IGF-1) levels by mimicking the action of the hormone ghrelin and binding to one of the ghrelin receptors (GHSR) in the brain. Activated GHSR (growth hormone secretagogue receptor), stimulates growth hormone release from the brain. GHSR are found in brain regions that control appetite, pleasure, mood, biological rhythms, memory, and cognition. Therefore, we can expect that ibutamoren may also affect these functions.
A great thing about ibutamoren is that it increases growth hormone levels with little or no increase in other hormones such as prolactin, glucose, triiodothyronine (T3), thyroxine (T4), thyrotropin, cortisol or insulin. For example, 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 Of Ibutamoren
MK-677 is orally active and can be taken once a day, and these are all the benefits compared to other growth hormone stimulators.
