HGH Fragment 176-191
Also known as AOD-9604 relative, GH frag
A small fragment of human growth hormone isolated for its fat-metabolism effects, studied for lipolysis without the broader actions of full growth hormone.
What it is
HGH Fragment 176-191 is exactly what its name suggests: amino acids 176–191 from the tail end of the human growth-hormone molecule. Researchers isolated this region because it appears to carry growth hormone's fat-burning properties.
How it's thought to work
The fragment is believed to stimulate lipolysis (the breakdown of stored fat) and inhibit lipogenesis (fat formation) — while largely avoiding the effects of full growth hormone on blood sugar and tissue growth. In other words, it targets the fat-metabolism part of the molecule specifically.
Potential health benefits
Investigated for:
- Targeted fat loss, particularly stubborn deposits.
- Body recomposition without strong growth-hormone-wide effects.
What the research says
Animal and early human work suggests a fat-metabolism effect, and the fragment is attractive in research precisely because it's more selective than whole growth hormone. Strong, large-scale human outcome data is limited.
Considerations
A research compound, not an approved medicine. Consult a qualified professional before considering use.
