How much bacteriostatic water to reconstitute BPC-157 (10 mg vial)?
For a 10 mg BPC-157 vial, the volume of bacteriostatic water you add sets the concentration: 1 ml gives 10 mg/ml; 1.5 ml gives 6.67 mg/ml; 2 ml gives 5 mg/ml; 2.5 ml gives 4 mg/ml; 3 ml gives 3.33 mg/ml. At the 2 ml reference volume the solution is 5 mg/ml (50 mcg per U-100 syringe unit). Research Use Only — these are solution concentrations, not amounts to administer.
| Bacteriostatic water | Concentration | Mass per U-100 unit |
|---|---|---|
| 1 ml | 10 mg/ml | 100 mcg |
| 1.5 ml | 6.67 mg/ml | 67 mcg |
| 2 ml | 5 mg/ml | 50 mcg |
| 2.5 ml | 4 mg/ml | 40 mcg |
| 3 ml | 3.33 mg/ml | 33 mcg |
Each “mass per U-100 unit” figure is the amount one unit on a U-100 insulin syringe (1 unit = 0.01 ml) holds at that concentration — a property of the prepared solution, not an amount to administer.

How to reconstitute BPC-157
BPC-157 is a synthetic pentadecapeptide supplied as a 10 mg lyophilized powder. To reconstitute it, draw bacteriostatic water into the syringe and release it slowly against the inside wall of the vial so the stream does not strike the powder directly; let the peptide dissolve on its own rather than shaking. This calculator takes the water volume you plan to add and returns the concentration in mg/ml, the mass held in one U100 syringe unit, and a mark-by-mark reference table. Volume is the input; mass is the output — it never solves backward from a target amount.
At the 10 mg vial strength the common reconstitution volumes map to a defined concentration band: 1 ml of bacteriostatic water gives 10 mg/ml, 2 ml gives 5 mg/ml, and 3 ml gives about 3.3 mg/ml. Every syringe mark in the table is scaled to whichever concentration your chosen volume produces.
BPC-157 reconstitution — frequently asked questions
How much bacteriostatic water should I add to a 10 mg BPC-157 vial?
That is your choice and it sets the concentration. The tool accepts any volume from 1 to 3 ml and shows the resulting mg/ml — more water lowers the concentration, less water raises it. The 10 mg vial reaches 10 mg/ml at 1 ml and about 3.3 mg/ml at 3 ml.
What concentration does a 10 mg BPC-157 vial reach?
Concentration is the vial’s 10 mg divided by the water volume in millilitres. Across the 1–3 ml range that is 10 mg/ml down to about 3.3 mg/ml. The calculator reports the exact value for your volume plus the mass at every U100 mark.
What solvent is used to reconstitute BPC-157?
Bacteriostatic water — sterile water with 0.9% benzyl alcohol as a preservative — is the standard laboratory solvent. Add it down the vial wall and let the pentadecapeptide dissolve without agitation.
How is reconstituted BPC-157 stored?
Keep the reconstituted solution refrigerated at 2–8°C and shielded from light; the lyophilized vial is held at −20°C until reconstituted. Aliquot before any freezing to avoid repeated freeze-thaw cycles.
