How to use
Select Syringe
Choose your insulin syringe size — 0.3 mL (30 IU), 0.5 mL (50 IU), or 1.0 mL (100 IU).
Enter Peptide Weight
Enter the lyophilised peptide mass in milligrams (e.g. 5 mg for a 5mg vial).
Enter Water Volume
Enter the volume of bacteriostatic water you added to the vial in millilitres.
Enter Your Dose
Enter your desired research dose in mcg or mg. The calculator instantly shows units to draw.
Formula reference
Concentration
(Peptide mg × 1000) ÷ Water mL
= mcg / mL
Volume to Draw
Dose (mcg) ÷ Concentration
= mL
Insulin Units
Volume (mL) × 100
1 mL = 100 IU
