HGH Fragment 176-191

HGH Fragment 176-191 (AOD-9604) is a modified 17–amino acid peptide derived from the C-terminal region of human growth hormone, with an added N-terminal tyrosine for stability. It has been studied for its interaction with lipid metabolism–related signaling pathways, particularly mechanisms associated with lipolysis and lipogenesis.

Unlike full-length human growth hormone, this fragment does not activate the classical growth hormone receptor pathway and has not been shown to significantly influence IGF-1 levels in research settings. Published data are limited to preclinical and clinical investigation contexts.
