Sermorelin is a growth hormone-releasing hormone (GHRH) that has been clinically proven to increase human growth hormone (HGH) levels.  Sermorelin acts on the hypothalamus to release growth hormone-releasing hormone (GHRH) that then stimulates the pituitary gland to make more HGH.  This subsequently increases insulin-like growth factor 1 (IGF-1), which in turn helps with fat breakdown, muscle growth, and the strengthening of bones.  Since Sermorelin stimulates the pituitary gland to produce its own HGH for the body, it eliminates the risks commonly associated with synthetic HGH, and makes Sermorelin a more natural and safer alternative.
