How it works
Concentration = peptide (mcg) ÷ water (mL). On a U-100 syringe each unit is 0.01 mL, so units to draw = dose ÷ concentration × 100.
For informational use with a prescription from your provider; never adjust a dose without talking to your care team. Double-check the vial label and syringe size before every injection.
