Overview

Mazdutide is an investigational peptide designed to activate both the GLP-1 and glucagon receptors, an approach based on the oxyntomodulin backbone. It has been evaluated in clinical trials but is not an approved medicine, and it appears here only for educational context.

How it’s thought to work

  • Reported to co-activate GLP-1 and glucagon receptors.
  • GLP-1 activity is commonly cited as supporting glucose-dependent insulin secretion and appetite reduction.
  • Glucagon-receptor activity is described in the literature as potentially increasing energy expenditure.
  • The dual approach is studied for combined effects on glucose and body weight.

Researched uses

  • Body-weight reduction in clinical trial populations
  • Glycemic control endpoints in type 2 diabetes studies
  • Explored in the literature for effects on hepatic fat

Reconstitution

If supplied as a lyophilized research vial, reconstituting 10 mg with 2 mL bacteriostatic water gives 5 mg/mL, so 1 mg would be about 20 units on a U-100 syringe. Figures are illustrative only.

Mazdutide dosage calculator

The calculator below is pre-filled with Mazdutide’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.

📋 In plain English

Add 2 mL of bacteriostatic water to your 10 mg vial. That gives you about 10 doses of 1 mg. For each dose, draw 20 units into a 100-unit insulin syringe.
