How It Works
This calculator determines how far to pull your insulin syringe based on the concentration of your reconstituted peptide. Your peptide amount (mg) divided by the water volume (mL) gives you the concentration, and your desired dose is converted to the matching syringe units.
Insulin syringes are marked in “units” where 100 units equals 1 mL. A 0.3 mL syringe goes up to 30 units, a 0.5 mL syringe goes to 50 units, and a 1.0 mL syringe goes to 100 units.
For best results, always use bacteriostatic water for reconstitution, store reconstituted peptides in the refrigerator, and follow sterile technique when drawing doses.
Quick Unit Reference
Volume
1 mL and 1 cc are the same measurement. They can be used interchangeably.
Syringe Units
100 units on an insulin syringe is equal to 1 mL (1 cc). 50 units = 0.5 mL, 10 units = 0.1 mL.
Weight
1 mg (milligram) = 1,000 mcg (micrograms). Most peptide doses are measured in mcg.
