Updated: Jul 26

HGH Fragment 176-191 is a synthetic peptide corresponding to a specific region of human growth hormone, studied in metabolic research for that fragment's isolated profile. This overview covers what it is and how it relates to AOD-9604.
What Is HGH Fragment 176-191?
HGH Fragment 176-191 is a synthetic peptide corresponding to the C-terminal region (amino acids 176-191) of human growth hormone. It was characterised to isolate that specific fragment, separate from the full hormone and its broader range of activity.
How Does HGH Fragment 176-191 Work?
It is studied in metabolic research for its interaction with lipid-metabolism pathways, independent of the broader growth-signalling activity of the full hormone. It is closely related in research framing to AOD-9604, which is based on the same region.
HGH Fragment 176-191 and AOD-9604
The two are derived from the same C-terminal region of human growth hormone and are frequently studied and discussed together.
Forms, Purity and Handling
