The HGH Fragment is a peptide that is based on amino acids 176-191 at the C-terminal region of the human growth hormone (HGH). Studies have shown that this peptide helps burn fat by mimicking the way natural HGH regulates fat metabolism. Unlike unmodified HGH, the HGH Fragment 176-191 does not have adverse effects on insulin sensitivity (blood sugar) or cell proliferation (muscle growth). In studies, it has been shown to reduce body fat, particularly in the abdominal area. The second most potent fat loss peptide is CJC-1295 (modified GRF 1-29) since it causes the overall GH level to rise in the body.
