How the math works
Reconstitution is just two steps. First, concentration: the peptide in the vial divided by the water you added: 10 mg in 2 mL is 5 mg/mL. Second, the draw: your dose divided by that concentration gives a volume, which the calculator converts to the unit marks on your syringe. On a U-100 syringe, 100 units is 1 mL, so a 0.05 mL dose is 5 units.
The "doses per vial" figure simply divides the vial's total content by your dose, rounded down to whole doses, which is handy for planning a reorder before you run out.
