Peptide calculator
Transparent unit conversion based on your inputs. This tool does not provide medical advice or recommended amounts.
Peptide calculator
Enter your dose, vial strength, and bacteriostatic water (BAC) volume. The tool shows concentration and draw volume — educational arithmetic only.
Dose of peptide
Strength of peptide
Water (BAC) of peptide

Results
Concentration (mg/mL) = 5.000 mg strength ÷ 2.000 mL BAC
= 2.5000 mg/mL
Draw volume (mL) = 0.2500 mg dose ÷ 2.5000 mg/mL
= 0.1000 mL
≈ 100.00 µL (microlitres)
Syringe preview
U-100 style markings (100 units = 1 mL). Visual guide only — verify with your syringe label.

10 units
0.100 mL · 100.0 µL
On a U-100 syringe, each numbered unit is 0.01 mL. Align the top of the plunger rubber with the dashed blue line (liquid meniscus level).
Worked example
Strength: 5 mg · Water (BAC): 2 mL → concentration 2.5 mg/mL. Dose 0.25 mg: 0.25 ÷ 2.5 = 0.1 mL (100 µL).
