AOD-9604 vs Tirzepatide: Fat Loss Research Compounds Compared (2026)

AOD-9604 vs Tirzepatide: Two Approaches to Fat Loss Research

AOD-9604 and Tirzepatide are both popular in weight management research, but they work through entirely different mechanisms. This comparison helps researchers understand which compound aligns with their specific study goals.

What Is AOD-9604?

AOD-9604 is a modified fragment of the growth hormone molecule (amino acids 177-191) designed to mimic the lipolytic (fat-burning) effects of growth hormone without affecting blood sugar or growth. It is studied for its potential to promote fat metabolism and is administered via subcutaneous injection.

What Is Tirzepatide?

Tirzepatide is a synthetic peptide that acts as a dual agonist at the GLP-1 and GIP receptors. This dual action enhances insulin sensitivity, slows gastric emptying, and reduces appetite, leading to significant weight loss in clinical studies. It is administered via once-weekly subcutaneous injection.

Key Differences

Factor AOD-9604 Tirzepatide
Mechanism GH fragment, lipolysis GLP-1 + GIP dual agonist
Primary effect Fat metabolism Appetite suppression + weight loss
Dosing 300-1000 mcg daily 2.5-15 mg weekly
Appetite effect Minimal Significant

Research Applications

AOD-9604 is often studied for targeted fat oxidation and metabolic research. Tirzepatide is extensively studied for obesity, insulin sensitivity, and glycemic control. For a deeper dive into GLP-1 class compounds, see our complete Semaglutide research guide and Tirzepatide research guide.

Which One for Your Research?

  • Choose AOD-9604 for studies focused on lipolysis and localized fat metabolism
  • Choose Tirzepatide for appetite, weight loss, and metabolic syndrome research
