HGH Fragment 176-191 (Human Growth Hormone Fragment 176-191)
The lipolytic fragment of human growth hormone (amino acids 176-191). Retains fat-burning properties of HGH without growth-promoting or diabetogenic effects.
How it works
Mimics lipolytic action of HGH by stimulating beta-3 adrenergic receptors on adipocytes, increasing cyclic AMP and hormone-sensitive lipase activity. Does not affect IGF-1.

Research
- Lipolytic effects of GH fragment 176-191 in obese mice (2018): Produced significant fat mass reduction without affecting lean mass, glucose, or IGF-1 levels.
- Fat metabolism modulation by GH peptide fragments (2020): 176-191 fragment stimulated lipolysis at rates comparable to full hGH while showing no diabetogenic potential.
