Peptide calculator
Find how much water to add and how many insulin-syringe units to draw for your target dose. Pick a peptide to auto-fill its range and estimate a starting point by body size and age.
Pick a peptide to auto-fill its dose and, where it applies, show the dose estimator — or use the calculator on its own.

A U-100 syringe reads 100 units per mL. This is a reconstitution math helper only, not a prescription or dosing advice. Verify every calculation and consult a qualified healthcare provider.
How it works
Add water
Draw bacteriostatic water into the vial with a syringe, along the glass so it does not hit the powder hard. Swirl gently — do not shake.
Read concentration
Vial strength ÷ water added = concentration per mL. A 10 mg vial with 2 mL of water is 5 mg/mL.
Draw units
A U-100 insulin syringe reads 100 units per mL. Target dose ÷ concentration × 100 gives the unit mark to draw to.
Common vial reference — mg per 10 units drawn
| Water added | 5 mg vial | 10 mg vial |
|---|---|---|
| 1 mL | 0.5 mg | 1 mg |
| 2 mL | 0.25 mg | 0.5 mg |
| 3 mL | 0.17 mg | 0.33 mg |
Educational reference only, not a prescription. Use the calculator above for your own vial and dose.
