Not sure how many units to draw on your syringe? Belle's Dosage Calculator does the math for you — just select your medication, vial concentration, and prescribed dose to see the exact number of units to draw.
How to use it
Select your medication — Tirzepatide or Semaglutide
Select your vial concentration — check the label on your vial (e.g., 10 mg/mL or 20 mg/mL)
Select your prescribed dose — choose from the preset options or enter a custom dose in mg
The calculator instantly shows:
The exact number of units to draw on your syringe
A syringe diagram showing where to draw to
Helpful context like volume per dose and how many doses are in your vial
Tips
Always check your vial label before selecting a concentration — it can change between shipments
If your result lands between two unit marks, the calculator tells you exactly where to draw (e.g., "Draw halfway between the 12 and 13 unit marks")
If you see a result over 100 units, double-check your selections — this is very rare with our prescriptions and usually means the wrong concentration was selected
Important
