Example Mazdutide Titration Schedule
| Phase | Weeks | Dose | Frequency |
|---|---|---|---|
| Start | Weeks 1–4 | 2 mg | 1× weekly |
| Titration 1 | Weeks 5–8 | 4 mg | 1× weekly |
| Target dose | Weeks 9+ | 6 mg | 1× weekly |
Approved in China (NMPA, June 2025) for chronic weight management at 4 or 6 mg once weekly. The 2.5–10 mg volume tables described research-vial dilutions, not the approved schedule.

Best Practices & Common Mistakes
Best Practices
- Use sterile technique.
- Protect from light and heat.
- Store refrigerated when appropriate.
- Use clean syringe-unit math before measuring.
Common Mistakes
- Confusing milligrams with milliliters.
- Choosing an option with awkward decimal units.
- Using too little liquid for very small measurements.
- Shaking the vial aggressively.
Mazdutide Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.

Frequently Asked Questions
It's dosed once weekly with slow escalation — research and the approved Chinese schedules step up roughly 2 → 3 → 4.5 → 6 mg (and higher doses like 9 mg are in late-stage trials), raising the dose every 4 weeks to limit nausea. These figures are shown for reference, not as a recommendation; dosing decisions belong with a licensed clinician.
It's a dual GCG/GLP-1 receptor agonist — it acts on the glucagon receptor as well as GLP-1, which is meant to raise energy expenditure on top of appetite suppression. It's notable as the first drug of its class approved (in China, in 2025, by Innovent and Lilly); outside China it remains investigational and not approved. For the calculator, the mechanism doesn't change the mg-to-units math.
They target different receptor combinations: tirzepatide is GLP-1/GIP, retatrutide is GLP-1/GIP/glucagon (triple), and mazdutide is GLP-1/glucagon — no GIP. The glucagon arm is the shared theme with retatrutide. They're separate molecules with their own concentrations, so the calculator handles each individually; pick the matching calculator and enter that compound's vial and dose.
It can. Mazdutide is sold as both an acetate and a TFA salt, and the calculator treats the entered mass as pure active peptide. If part of the vial's weight is the salt, entering the total mg can slightly overstate the active amount. Check the Certificate of Analysis (CoA) for the free-base (net peptide) figure and enter that for the most accurate units.
Its long half-life — engineered through a fatty-diacid chain that binds plasma albumin and slows clearance — supports once-weekly injection rather than daily. Because it's long-acting, levels build over the first several weeks before reaching a steady state, so a single-dose calculation describes your first injection while later weekly troughs sit higher.
Practical takeaway: If your goal involves weight management, metabolic health, recovery, physical performance, cognitive function, appearance, or general well-being, discuss it with a licensed healthcare professional. They can help you evaluate approved, evidence-based options rather than relying on an unapproved or investigational compound. This calculator is intended only for transparent research-reference calculations and does not determine an appropriate amount, recommend use, or replace professional medical guidance.
