Mazdutide
Also known as: Peptide-M · IBI362 · GLP-1/Gcg receptor agonist
A GLP-1 and glucagon receptor co-agonist developed by Innovent Biologics. In Phase 3 clinical trials in China with strong efficacy data. Shows comparable weight loss to tirzepatide while also reducing liver fat. Also studied for type 2 diabetes management.
What is Mazdutide? A GLP-1 and glucagon receptor co-agonist developed by Innovent Biologics. In Phase 3 clinical trials in China with strong efficacy data. Shows comparable weight loss to tirzepatide while also reducing liver fat. Also studied for type 2 diabetes management.
How does Mazdutide work? Mazdutide activates both GLP-1R and glucagon receptor with a balanced agonism ratio. GLP-1R activation drives appetite suppression and glucose control; glucagon receptor activation increases resting energy expenditure and promotes hepatic lipid oxidation. Together these pathways produce robust weight loss with additional metabolic benefits.
Benefits of Mazdutide: Robust weight loss: 12-15% body weight in Phase 3 trials; Dual GLP-1 and glucagon receptor activation; Significant reduction in liver fat (NASH application); Glucose control improvement; Once-weekly dosing; Strong Phase 3 data from Chinese clinical trials
Mazdutide dosage: Phase 3 doses used: 3-9mg/week. Titration protocol recommended. Not yet FDA approved.

Mechanism of Action
Mazdutide activates both GLP-1R and glucagon receptor with a balanced agonism ratio. GLP-1R activation drives appetite suppression and glucose control; glucagon receptor activation increases resting energy expenditure and promotes hepatic lipid oxidation. Together these pathways produce robust weight loss with additional metabolic benefits.

Storage & Reconstitution Guide
Storage Temperature
-20°C lyophilized, 4°C reconstituted
24 months (lyophilized), 28 days (reconstituted)
Reconstitution Solvent
Bacteriostatic water (BAC water)
Swirl gently — do not shake or vortex
Handling Notes
Protect lyophilized peptide from moisture and light. Once reconstituted, keep refrigerated. Discard if solution becomes cloudy or discolored. Use insulin syringe for precise dosing.
