HGH Fragment 176–191 5mg – 3ml Vial
Product Overview
HGH Fragment 176–191 corresponds to the C-terminal region of human growth hormone and represents residues 176 through 191 of the full-length 191-amino-acid hGH molecule. This fragment has been structurally isolated for laboratory investigation into metabolic signalling independent of the broader systemic activity associated with intact growth hormone.
In controlled in-vitro and pre-clinical research models, HGH Frag 176–191 is utilised to investigate:
- Adipocyte receptor signalling mechanisms
- Lipolytic pathway modulation
- AMPK-associated metabolic signalling
- Fat oxidation pathway research
- Structure–activity relationships within the GH molecule
Unlike full-length hGH, this fragment does not activate the complete GH receptor cascade, making it suitable for focused mechanistic research into lipid metabolism-associated pathways.
Supplied in lyophilised form to preserve peptide stability and analytical integrity prior to reconstitution.

Handling & Storage Guidelines
Unreconstituted (Lyophilised) Storage:
Store at −20°C for long-term preservation. Short-term storage at 2–8°C is acceptable if intended for use within 1–3 months.
Reconstituted Storage:
After reconstitution, store at 2–8°C and use within 3–6 weeks. Stability may vary depending on solvent selection and handling conditions.
Avoid repeated freeze–thaw cycles. Protect from excessive agitation, heat, and direct light exposure.
