BPC-157 reconstitution calculator
Enter your BPC-157 vial size and the bacteriostatic water you are adding. The calculator shows the resulting concentration and marks the exact units on a U-100 or U-40 syringe.
BPC-157 is usually dosed in micrograms from a 5 mg or 10 mg vial, which makes small measurement errors matter. Enter your numbers to see the draw marked on the syringe.
Verify every dose with your prescriber or pharmacist.

How to reconstitute BPC-157
Reconstitution is arithmetic, not chemistry. The milligrams in the vial divided by the millilitres of bacteriostatic water gives the concentration in mg/mL. Your dose divided by that concentration gives the injection volume, and that volume multiplied by your syringe's units-per-mL gives the units to draw. More water means a lower concentration and more units for the same dose, which is easier to measure accurately.
BPC-157 calculator FAQ
- How much bacteriostatic water should I add to a BPC-157 vial?
- There is no single correct amount. More water makes small doses easier to measure; less water keeps the injection volume down. The right choice depends on your prescription and product, so decide it with your prescriber or pharmacist — this calculator only shows the maths for the numbers you enter.
- Does adding more water change the dose?
- No. The amount of BPC-157 in the vial is fixed. Extra water spreads the same milligrams across more volume, so you draw more units for the same dose.
