Research Tool
Semaglutide is supplied lyophilized at milligram vial masses, so working concentrations are expressed in mg/mL and the volumes involved are small. Enter the Semaglutide mass in the vial and the diluent volume to get the stock-solution concentration.

Concentration (mg/mL) = peptide mass (mg) ÷ diluent volume (mL). For in-vitro laboratory research use only.
A 10 mg vial in 2 mL gives 5 mg/mL; a 30 mg vial in the same 2 mL gives 15 mg/mL. Halving the volume doubles the concentration — the mass in the vial does not change, only how it is distributed.
