Peptide Dose Calculator
Instantly compute how many units to draw on your insulin syringe based on the peptide amount in the vial, the bacteriostatic water you added and your target dose. The result updates automatically as you change the values.
10 units to draw
Fill the syringe up to this mark.
- Volume to draw
- 0.1 ml
- Concentration
- 2500 mcg/ml
- Doses per vial
- 20 doses
How is it calculated?
The peptide dose calculation has three steps:
- Concentration = (Vial mg × 1000) ÷ Water volume (ml) → mcg/ml
- Volume to draw = Target dose (mcg) ÷ Concentration (mcg/ml) → ml
- Units to draw = Volume (ml) × 100 → units on a U-100 insulin syringe
On U-100 insulin syringes 1 ml = 100 units, so multiplying the volume by 100 gives you the exact unit mark on the syringe.
Example
5 mg peptide + 2 ml water → 2500 mcg/ml. For a 250 mcg dose: 250 ÷ 2500 = 0.1 ml = 10 units.
