The Science Behind HGH Fragment 176-191

The discovery that the lipolytic activity of human growth hormone resides in its C-terminal region was a significant breakthrough in endocrinology research. Full-length hGH has multiple biological effects mediated through different domains of the molecule . The N-terminal region is associated with growth-promoting and insulin-like activities, while the C-terminal region (amino acids 177-191) is responsible for lipid-mobilizing effects .

HGH Fragment 176-191 was developed to isolate these lipolytic properties. Research has demonstrated that this fragment:  HGH fragment 176-191

• Stimulates lipolysis in isolated adipocytes

• Reduces fat accumulation in animal models

• Does not affect linear growth or organ size

• Does not alter insulin sensitivity

• Does not stimulate IGF-1 production

These properties make HGH Fragment 176-191 a valuable research tool for investigating adipose tissue metabolism independent of the complex effects of full-length growth hormone.
