Semaglutide calculator.
Work out the reconstitution for a Semaglutide vial. Enter the mg in the vial and the bacteriostatic water you add, and it returns the concentration in mg/mL and the volume in U-100 syringe units. Pre-filled with a common 5 mg vial — change it to match yours. Arithmetic only: it never suggests how much to use.

REFERENCESemaglutide is a metabolic peptide with an approximate half-life of ~7 days. The arithmetic above is the same for every compound — only the concentration changes with how you reconstitute. For mechanism, the evidence base, common research dose ranges and vendor pricing, see the full Semaglutide guide, and the main peptide calculator for worked examples and the full method.
Common questions.
FAQHow do you work out Semaglutide syringe units?
Reconstitute the vial, then divide the amount you want to draw by the concentration — mg of Semaglutide in the vial divided by mL of bacteriostatic water — to get the volume in mL, and multiply by 100 for U-100 syringe units. The calculator above does it once you enter your vial and water.
How many units is 1 mg of Semaglutide?
It depends on how you reconstitute it, not on the compound. A 5 mg Semaglutide vial mixed with 2 mL of bacteriostatic water is 2.5 mg/mL, so 1 mg is 40 units on a U-100 syringe. Use more water and the same 1 mg is more units.
What size vial does Semaglutide come in?
Research Semaglutide is commonly sold around 5 mg per vial, but sizes vary by vendor. The calculator works for any size — enter the mg printed on your label and the water you added.
