How Does MK-667 (Ibutamoren) Work?
Because its component chemicals mimic the ghrelin, a hormone occurring naturally in the body, it functions as a neuropeptide in the central nervous system and the blood-brain barrier. It also activates the Ghrelin receptor which then stimulates the pituitary glands and the hypothalamus releasing somatropin and IGF. High IGF for its part helps enhance the growth of muscle mass.
Using MK-667 can make a person extremely hungry. It metabolizes fat in the body which aids in recovery from obesity and type 2 diabetes as well as helping produce and redistribute energy in the body. It also helps increase HGH production and will not interfere with other hormones when used alone. Ibutamoren does not suppress the natural growth hormones and testosterone in the body.
