AOD-9604
WellnessAlso known as: Advanced Obesity Drug 9604, Anti-Obesity Drug 9604, Tyr-hGH Fragment 177-191
Limited EvidenceWhat is AOD-9604?
A modified fragment of human growth hormone (amino acids 177-191) developed for fat loss. Despite promising early research, it failed to demonstrate efficacy in large clinical trials and was not approved by the FDA.
How it works
Mimics the lipolytic (fat-burning) region of growth hormone without affecting blood sugar or growth. Stimulates the breakdown of stored fat (lipolysis) and inhibits the formation of new fat (lipogenesis) by acting on beta-3 adrenergic receptors in adipose tissue.
What marketers claim
- ▸melts body fat without exercise
- ▸no side effects since it is a natural GH fragment
- ▸proven weight loss peptide
- ▸safe alternative to GLP-1 drugs
What evidence supports
- ✓early-phase trials showed some fat reduction potential
- ✓does not appear to affect IGF-1 levels or blood glucose
- ✓phase IIb clinical trial failed to show significant weight loss vs placebo
- ✓TGA (Australia) approved it as a complementary medicine ingredient

Frequently asked questions
Does AOD-9604 actually work for fat loss?
The phase IIb clinical trial failed to show significant weight loss compared to placebo. Despite early promising results, the manufacturer discontinued development. Current marketing claims for AOD-9604 significantly overstate what the evidence supports.
Is AOD-9604 safer than full growth hormone?
AOD-9604 does not appear to affect IGF-1 levels or blood glucose, which are concerns with full GH. In that narrow sense it has a more limited side effect profile. However, the fact that it also does not appear to work for its intended purpose (fat loss) makes the safety advantage largely academic.
