Also known as: Advanced Obesity Drug 9604, Anti-Obesity Drug 9604, Tyr-hGH Fragment 177-191

Limited Evidence

What 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

Best for

understanding as a cautionary example of peptide marketing vs evidence

Safety notes & concerns

  • failed to demonstrate efficacy in controlled clinical trials
  • not FDA approved — the manufacturer discontinued development
  • evidence does not support the strong fat-loss claims made by sellers
  • unregulated supply chain with purity concerns
  • injection carries infection risk without proper medical oversight

Pairs well with

structured diet and exercise programs remain more evidence-based for fat loss
