The 5 mg vial (+ 3 mL bacteriostatic water) Worked out step by step at the documented 100 mcg dose (remember 100 mcg = 0.1 mg): Concentration: 5 mg 3 mL = 1.67 mg/mL Draw volume: 0.1 mg 1.67 mg/mL = 0.06 mL Units: 0.06 mL 100 = 6 units The 10 mg vial (+ 3 mL bacteriostatic water) Same diluent volume, double the powder, so the solution is twice as concentrated and the same dose occupies half the volume: Concentration: 10 mg 3 mL = 3.33 mg/mL Draw volume: 0.1 mg 3.33 mg/mL = 0.03 mL Units: 0.03 mL 100 = 3 units This is the single most important thing to internalize: the same 100 mcg dose is 6 units from a 5 mg vial but only 3 units from a 10 mg vial
