Side-by-side comparison
| Rusfertide | Semaglutide | |
|---|---|---|
| Category | Weight Management & Metabolic | Weight Management & Metabolic |
| Regulatory status (US) | FDA approved | FDA approved |
| Typical dosage | 19-108 mg | 0.25-2.4 mg |
| Frequency | once weekly, subcutaneous | weekly |
| Reported benefits | In the Phase 3 VERIFY trial, adding rusfertide to standard-of-care therapy allowed 76.9% of participants to achieve hematocrit control without phlebotomy during weeks 20-32, compared with 32.9% on placebo plus standard of care. Reported benefits are specific to polycythemia vera erythrocytosis management and have not been studied for other conditions. | Significant weight loss, improved blood sugar control, reduced cardiovascular risk, appetite suppression |
| Reported side effects | Injection-site reactions (56%) and anemia (16%) were the most common adverse events in clinical trials; labeled warnings include thrombocytosis and embryo-fetal toxicity. | Nausea, vomiting, diarrhea, constipation, potential pancreatitis risk |
Key differences

Dosing. Rusfertide is typically dosed at 19-108 mg (once weekly, subcutaneous). Semaglutide is typically dosed at 0.25-2.4 mg (weekly).
Can you stack them?
Some protocols combine peptides, but stacking Rusfertide and Semaglutide has not been validated for safety or efficacy in controlled trials. Combining compounds can change their effects and risks. Nothing here is medical advice — consult a qualified healthcare provider before starting or combining any protocol.
