Mazdutide Reconstitution Calculator & Dosage Chart

Also known as: IBI362, LY3305677

Quick answer: mix a 10 mg vial of Mazdutide with 2 ml of bacteriostatic water. That gives 5.00 mg/ml, so a typical 4 mg dose is 80 units on a U-100 insulin syringe — about 2 doses per vial. Reported protocols range 3 mg9 mg, 1x weekly, titrated up.

Mazdutide is a GLP-1/glucagon dual agonist developed by Innovent and Eli Lilly, approved in China (2025) for weight management after GLORY-1 showed ~15% weight loss at 6 mg over 48 weeks. Outside China it remains investigational. Full overview: what is Mazdutide? →

FAQ

How much bacteriostatic water do you add to Mazdutide?+

Most protocols mix a 10 mg vial of Mazdutide with 2 ml of bacteriostatic water. This gives 5.00 mg/ml, so a typical 4 mg dose is 80 units on a U-100 insulin syringe. More or less water is fine — it only changes the volume you draw, not the dose.

What is a typical Mazdutide dose?+

Commonly reported Mazdutide protocols use 3 mg to 9 mg, 1x weekly, titrated up, administered via subcutaneous injection. These are reference figures from published protocols, not medical advice — individual use should be guided by a healthcare provider.

How many doses are in a 10 mg vial of Mazdutide?+

At 4 mg per dose, a 10 mg vial contains about 2 doses, regardless of how much water you add.

How should Mazdutide be stored?+

Reconstituted: refrigerate; typically used within 4–8 weeks.
