Retatrutide vs Mazdutide
An educational, source-based comparison of Retatrutide and Mazdutide — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic peptide that simultaneously agonizes GLP-1, GIP, and glucagon receptors. The glucagon component is hypothesized to add energy expenditure on top of the appetite suppression and insulinotropic effects of GLP-1/GIP.
- Obesity and weight loss (Phase 3)
- Type 2 diabetes
- NAFLD/MASH
- • Investigational; not FDA-approved (Phase 3 ongoing).
- • GI side effects common, similar to other incretin therapies.
- • Requires physician oversight.
A dual agonist of GLP-1 and glucagon receptors, similar to survodutide. The glucagon component increases energy expenditure while GLP-1 suppresses appetite and improves glycemic control.
- Chronic weight management
- Type 2 diabetes
- MASH / NAFLD
- • Investigational; not FDA-approved.
- • Glucagon agonism may affect heart rate and blood pressure.

Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Retatrutide | Triple-hormone-receptor agonist retatrutide for obesity | New England Journal of Medicine | 2023 | Phase 2 trial showed up to ~24% body weight reduction at 48 weeks. |
| Mazdutide | Mazdutide for obesity: Phase 2 results | The Lancet Diabetes & Endocrinology | 2024 | Achieved ~15% mean weight loss at 48 weeks with manageable side effects. |
