AOD-9604 is a synthetic peptide derived from the 177–191 amino acid sequence of human growth hormone (hGH), designed to stimulate lipolysis (fat breakdown) and inhibit lipogenesis (fat formation) without elevating IGF-1 or affecting glucose metabolism.  

​

AOD-9604 stands for "Anti-Obesity Drug-9604." Researchers isolated and modified the specific portion of hGH responsible for fat metabolism, hoping to create a targeted peptide that promotes weight loss without triggering the full spectrum of effects associated with growth hormone therapy.  

​

How It Works

Research suggests that AOD-9604 may activate beta-3 adrenergic receptors in fat cells, leading to enhanced fat oxidation — allowing individuals to experience fat reduction without the muscle growth or insulin resistance risks often associated with full-spectrum growth hormone therapies.  

 

Key Benefits

Fat Burning & Body Composition

The primary benefit documented in research is the enhancement of fat metabolism and reduction in body weight gain. In animal studies, AOD-9604 treatment reduced body weight gain by over 50% compared to controls over a 19-day period, with increased lipolytic activity in adipose tissue. The peptide's ability to activate lipolysis while inhibiting lipogenesis creates optimal conditions for fat loss while preserving lean tissue.  

 

Targeted Stubborn Fat

AOD-9604 appears especially effective at mobilizing fat from areas resistant to traditional diet and exercise interventions.  

 

Metabolic Support

Some research reports improved lipid balance (triglyceride reduction) in preclinical studies, with possible improvements in basal metabolic rate also noted — suggesting broader metabolic effects beyond fat burning.  (Honest Peptide)

 

Joint & Cartilage Health

AOD-9604 demonstrated chondroprotective effects in models of cartilage degradation, and may reduce proteoglycan loss and support collagen maintenance.
