Beginner setup
Vial sizes vary by vendor. Smaller bottles are usually 3 mL; larger bottles are often 10 mL. Match the label on the vial you actually bought, then use the calculator below if you need to adjust.
Vial strength 5 mg
Bottle format often 3 mL
BAC water 3 mL
Concentration 1.67 mg/mL
Overview
Mazdutide is a dual GLP-1 and glucagon receptor agonist. The glucagon component adds energy expenditure on top of GLP-1 appetite suppression, which is why it targets both weight loss and metabolic health.
Preparation
Reconstitute a 5 mg vial with 3 mL of bacteriostatic water (BAC) for a ~1.67 mg/mL concentration. Gently roll the vial to dissolve; do not shake.
| Vial | BAC | Concentration |
|---|---|---|
| 5 mg | 3 mL | 1.67 mg/mL |
Protocol
| Period | Dose | Units (@ 1.67 mg/mL) | Frequency |
|---|---|---|---|
| Weeks 1–4 | 2.5 mg (2,500 mcg) | 150 units (1.50 mL) | 1x/week |
| Weeks 5–8+ | 5 mg (5,000 mcg) | 300 units (3.00 mL) | 1x/week |
Cycle
Weekly injections on a consistent day. The 3 mL dilution keeps maintenance doses measurable, but 5 mg requires a 3 mL syringe. 8-week protocols use roughly 6 vials.
