AOD-9604 vs Tesofensine

Side-by-side comparison of key properties, dosing, and research.

Fat Loss & Metabolic
AOD-9604
Fat Loss & Metabolic
Tesofensine
Summary
AOD-9604 is a modified fragment of human growth hormone (residues 177-191) with an additional tyrosine residue that significantly enhances bioavailability. Originally developed as an anti-obesity drug by Metabolic Pharmaceuticals, it stimulates lipolysis and inhibits lipogenesis without the diabetogenic effects of full GH.
Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.

Key Benefits
  • Selective fat loss without anabolic side effects
  • No effect on blood glucose or insulin resistance
  • Improved bioavailability over Fragment 176-191
  • GRAS (Generally Recognized As Safe) status in Australia
  • Potential cartilage repair and anti-inflammatory properties
  • Does not suppress natural GH production
  • Potent appetite suppression via triple monoamine reuptake inhibition
  • Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
  • Increases basal metabolic rate and energy expenditure
  • Reduces fat mass preferentially over lean mass
  • Potential cognitive benefit via dopaminergic and noradrenergic enhancement
  • Longer half-life than sibutramine allows once-daily dosing
Side Effects
  • Localized injection site reactions
  • Headache (rare)
  • Hypoglycemia risk in combination with insulin (very rare)
  • Elevated heart rate and blood pressure (sympathomimetic)
  • Dry mouth
  • Insomnia and sleep disturbances
  • Nausea
