Semaglutide dose calculator
Calculate a semaglutide weekly dose draw in U-100 syringe units and milliliters from a research-vial concentration.
What this calculator returns
- The U-100 insulin syringe unit count for the chosen weekly semaglutide dose.
- The equivalent draw volume in milliliters.
- Default presets that mirror the FDA-approved Wegovy and Ozempic label dose steps (0.25, 0.5, 1, 1.7, 2, 2.4 mg weekly).
Formula and example
Semaglutide vial draw math uses the same GLP-1 conversion formula: dose in mg divided by concentration in mg/ml equals ml.
The U-100 unit count is the ml draw multiplied by 100.
Worked example: A 1 mg weekly dose from a 5 mg/ml semaglutide vial equals 0.2 ml, or 20 U-100 units.
Warnings and boundaries
- Ozempic, Wegovy, and oral Rybelsus are FDA-approved branded products with their own instructions.
- Compounded semaglutide is not FDA-approved.
- The calculator returns math for the concentration entered, not a sourcing or dosing endorsement.
