Certificate Reference
For continuity with the current catalog, this page links to laboratory documentation for a component or a closely related product. The linked certificate is a reference only and is not represented as the batch-specific COA for HGH Fragment 176-191.
Overview
HGH Fragment 176-191 is the natural 16-residue C-terminal fragment of human growth hormone. It is studied because this region overlaps the lipolytic domain of HGH, making it useful for separating lipid-metabolism signaling from the broader growth and IGF-1 effects of the intact 191-amino-acid hormone.

Research Focus
WHAT THIS FORMULA FEATURES
The main research interest is adipocyte and lipid-metabolism signaling. A closely related modified analog, AOD-9604, adds an N-terminal tyrosine and has published preclinical data showing increased lipolysis and fat oxidation. The natural 176-191 fragment is chemically distinct, so AOD findings should be treated as supportive pathway context rather than direct proof.
EXPECTED RESEARCH READOUTS
Researchers typically evaluate glycerol release, lipolytic activity, fatty-acid oxidation, adipocyte signaling, glucose/insulin-related markers, and comparisons with intact HGH or AOD-9604. Exact-fragment evidence is more limited than the evidence for the modified AOD analog.
Research endpoints described above reflect published or model-based scientific observations and are not guaranteed outcomes. This product is strictly for research purposes only. Not approved for human or animal use.
