The HGH Fragment is a modified form of amino acids 176-191 at the C-terminal region of the human growth hormone (HGH). Studies have shown that it works by mimicking the way natural HGH regulates fat metabolism but without the adverse effects on insulin sensitivity (blood sugar) or cell proliferation (muscle growth) that is seen with unmodified HGH. Like unmodified GH, the HGH fragment 176-191 stimulates lipolysis (breaking down of fat) and inhibits lipogenesis (the formation of fatty acids and other lipids in the body).
HGH fragment 176-191 is meant to be 12.5 times stronger than human growth hormone (HGH) for weight loss than standard human growth hormone (HGH).
Of particular note is that in studies HGH fragment 176-191 had the ability to increase IGF-1 levels which translates into the fragments ability to give anti-aging effects.
