HGH Fragment 176‑191 is a synthetic peptide derived from the C‑terminal region of human growth hormone (hGH). It includes amino acids 176 through 191 of the hGH sequence and is designed to retain fat‑metabolizing (lipolytic) activity without the broader effects of full growth hormone. In research settings, this peptide is studied for its influence on fat breakdown, energy regulation, and metabolic pathways.
Sequence & Identity:

Typical Research Uses:
-
Studying lipolysis (fat metabolism) pathways in cellular models
-
Investigating metabolic effects separate from full HGH action
-
Exploring peptide regulation of energy balance and adipose tissue response
-
Testing peptide interaction with hormone receptors or metabolic enzymes
Important Notes:
-
For laboratory research use only — HGH Fragment 176‑191 is not FDA‑approved for clinical use, human consumption, or therapeutic applications.
-
Always follow appropriate lab safety protocols, including sterile technique and PPE when handling peptides.
