Peptide Dose Calculator
Convert a desired dose into injection volume and U-100 insulin syringe units.
1. Calculate Injection Volume
Fill is shown on a 100-unit U-100 syringe scale.
Injection volume
0.000mL
U-100 syringe
0.0units
Formula: injection volume = desired dose / total vial amount x reconstitution volume. U-100 insulin units = mL x 100.
2. How This Calculator Works
The calculator first converts the desired dose and total vial amount into micrograms, then calculates the fraction of the vial represented by the dose. That fraction is multiplied by the reconstitution volume to estimate how many milliliters to draw.
For U-100 insulin syringes, 1 mL equals 100 units. A result of 0.05 mL is therefore 5 units, and 0.25 mL is 25 units.
3. Example
If a vial contains 5 mg of peptide and was reconstituted with 2 mL, the vial contains 2.5 mg/mL. A 250 mcg dose equals 0.25 mg, which is one tenth of the vial. One tenth of 2 mL is 0.2 mL, or 20 U-100 syringe units.
4. Important Limits
- IU conversions are peptide-specific and are not included in this web calculator.
- The result assumes the vial is evenly mixed after reconstitution.
- This calculator does not determine what dose you should take.
- Always follow instructions from your clinician, pharmacist, or prescribing documentation.
