Work out exactly how many units to draw on your syringe for a target dose.
Units are marked on an insulin syringe. They are not your dose — they tell you how far to draw the plunger.
How this works. When you reconstitute a peptide, you mix the lyophilized powder with bacteriostatic water. The amount of water you add sets the concentration. Divide your target dose by that concentration to get the volume to inject, then convert to units on the syringe.
Concentration = peptide (mcg) ÷ water (ml)
Volume per dose (ml) = dose (mcg) ÷ concentration (mcg/ml)
Units = volume (ml) × units-per-ml of your syringe
Doses per vial = total peptide (mcg) ÷ dose (mcg)
