AOD-9604

AOD-9604 (Advanced Obesity Drug) is a modified fragment of human growth hormone (HGH), specifically amino acids 176-191. It was originally developed as an anti-obesity drug by Monash University in Australia.

AOD-9604 retains the fat-reducing activity of HGH without its growth-promoting or diabetogenic effects. It stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat formation) without affecting blood sugar levels or causing cellular proliferation.

AOD-9604 received GRAS (Generally Recognized As Safe) status from the FDA as a food supplement ingredient. However, it is not FDA-approved as a drug. It is available through compounding pharmacies for off-label use in weight management protocols.

Potential Benefits

  • Fat loss without affecting muscle mass
  • Stimulation of lipolysis (fat breakdown)
  • Inhibition of lipogenesis (fat formation)
  • No effect on blood sugar or insulin
  • No growth-promoting effects
  • Cartilage repair support

Clinical trials showed modest fat loss effects; it is often used as part of comprehensive weight management protocols.

Mechanism of Action

AOD-9604 mimics the lipolytic fragment of growth hormone:

  • ↑ Lipolysis through beta-3 adrenergic receptor pathway
  • ↓ Lipogenesis (new fat cell formation)
  • No interaction with GH receptor (no IGF-1 increase)
  • No effect on glucose metabolism
  • Stimulation of cartilage and bone repair
  • Calorie-independent fat metabolism

Its selectivity for fat metabolism without broader GH effects makes it a targeted approach to fat loss.

Most Common Side Effects

  • Injection site irritation
  • Headache
  • Mild nausea
  • Fatigue
  • Dizziness

Contraindications

  • Active malignancy
  • Pregnancy or breastfeeding
  • Known hypersensitivity
  • Severe hepatic or renal impairment
