Reading the scale: the highlighted mark corresponds to the calculated volume on a standard U-100 insulin syringe — 100 units = 1 mL, and each numbered tick is one unit.
Reconstituting Semaglutide Peptide
Semaglutide is stocked in a single 10 mg vial, which removes the ambiguity the three-size GLP-1s carry: one mass, so diluent volume is the only variable and concentration follows directly. 1 mL gives 10 mg/mL, 2 mL gives 5, 5 mL gives 2. With the molecular weight on file at 4113.58, molar concentration is available alongside mass — and the roughly 700-dalton gap between semaglutide and tirzepatide means equal mass concentrations of the two are not equal molar concentrations, a distinction that only surfaces when both are computed.
