Mazdutide Dosage

GLP-1 / glucagon dual agonist

Mazdutide has no FDA label, so every dose figure here traces back to its published trials rather than a prescribing guideline. Its Phase 2 obesity trial tested once-weekly subcutaneous doses of 3 mg, 4.5 mg, and 6 mg over 24 weeks, and the Phase 3 GLORY-1 trial used 4 mg and 6 mg over 48 weeks with staged escalation.[1][2][3]

Dosing

Published trials used once-weekly subcutaneous doses with staged escalation. An illustrative low-to-mid schedule from the Phase 2 and GLORY-1 protocols:

Weeks 1–43 mg
Weeks 5–84 mg
Weeks 9+6 mg (maintenance)
Illustrative schedule from published trial protocols; mazdutide is investigational, so there is no approved prescribing dose.Higher-dose arm (GLORY-2)

A separate Phase 3 trial studied a 9 mg maintenance dose reached with a two-step titration:

TitrationStep up over ~8 weeks
Maintenance9 mg weekly
The 9 mg arm produced the largest reported weight loss but also the most gastrointestinal effects. Numbers describe what was studied, not a recommendation.

A separate Phase 3 trial, GLORY-2, studied a higher 9 mg maintenance dose reached with a two-step titration, which produced the largest reported weight loss but also more gastrointestinal effects. The titration approach below mirrors the stepwise design of these studies: start low and increase gradually so the gut can adjust.

Because mazdutide is investigational outside China, treat these numbers as a description of what was studied, not a recommendation. The data also come largely from Chinese trial populations, which may limit how well they generalize.

FAQ

What mazdutide doses were used in trials?The Phase 2 obesity trial used once-weekly subcutaneous 3 mg, 4.5 mg, and 6 mg; GLORY-1 used 4 mg and 6 mg; and GLORY-2 studied a 9 mg maintenance dose. There is no approved dose for independent use because mazdutide is investigational outside China.
Why titrate up slowly?Gastrointestinal side effects in the trials were dose-related, so stepping the dose up gradually is how studies aimed to keep nausea, diarrhea, and vomiting tolerable.
