AOD-9604 Deep Dive

AOD-9604 is a modified fragment of human growth hormone (hGH) that stimulates lipolysis (fat breakdown) without the anabolic effects of full GH. Animal studies show fat reduction, but human clinical trials have not demonstrated significant weight loss. It failed to meet primary endpoints in Phase III trials for obesity.

Semaglutide Deep Dive

Semaglutide has the most robust clinical evidence base of any weight loss peptide, with 10–15% average body weight reduction in large-scale randomized controlled trials.

How to Choose

Choose AOD-9604 if…

  • You are specifically researching GH fragment mechanisms
  • You want a non-prescription option (with the understanding that evidence is very limited)

Choose Semaglutide if…

  • Weight loss is your primary goal and you want proven results
  • You are willing to use a prescription medication
  • Clinical evidence is important to you

Consider Both If…

The evidence strongly favors Semaglutide for weight loss. AOD-9604 is not recommended as a primary weight loss intervention based on current evidence.
