Semaglutide vs Mazdutide
An educational, source-based comparison of Semaglutide and Mazdutide — how each peptide works, what it's researched for, and what to know before going deeper.
A long-acting GLP-1 receptor agonist that enhances glucose-dependent insulin secretion, suppresses glucagon, slows gastric emptying, and reduces appetite via central GLP-1 receptors.
- Type 2 diabetes (Ozempic, Rybelsus)
- Obesity / chronic weight management (Wegovy)
- Cardiovascular risk reduction (SELECT trial)
- • FDA-approved with established safety profile but real side effects (GI, pancreatitis risk, gallbladder events).
- • Requires physician oversight and prescription.
- • Compounded versions vary in quality.
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 |
|---|---|---|---|---|
| Semaglutide | Semaglutide for weight loss in adults with overweight or obesity (STEP 1) | New England Journal of Medicine | 2021 | Mean ~15% weight loss at 68 weeks versus placebo. |
| Semaglutide | Cardiovascular outcomes with semaglutide (SELECT) | New England Journal of Medicine | 2023 | Reduced MACE in adults with CVD and overweight/obesity. |
| Mazdutide | Mazdutide for obesity: Phase 2 results | The Lancet Diabetes & Endocrinology | 2024 | Achieved ~15% mean weight loss at 48 weeks with manageable side effects. |
