How to Use This Peptide Calculator
1
Enter Peptide Amount
Input the total milligrams (mg) in your peptide vial. Common sizes: 2mg, 5mg, 10mg.
2
Add Water Volume
Enter how much bacteriostatic water (BAC water) you'll add. More water = easier to measure small doses.
3
Set Your Dose
Enter your desired dose in micrograms (mcg). The calculator shows exact syringe units to draw.

The Math Behind Peptide Reconstitution
Concentration formula:
Concentration (mg/mL) = Peptide (mg) ÷ Water (mL)Units to draw:
Units = [Dose (mcg) ÷ 1000] ÷ Concentration × 100Example: BPC-157 250mcg dose
- 5mg vial + 2mL BAC water = 2.5 mg/mL
- 250mcg = 0.25mg
- 0.25mg ÷ 2.5 mg/mL = 0.10mL
- 0.10mL × 100 = 10 units on insulin syringe

Explore Peptide LabUnderstanding Insulin Syringe Units
10 units = 0.10 mL
Quick Reference
- 100 units = 1 mL (full syringe)
- 50 units = 0.5 mL (half syringe)
- 10 units = 0.1 mL (1/10th syringe)
- 1 unit = 0.01 mL
Standard insulin syringes are U-100, meaning 100 units per mL. This calculator uses this standard.
