BPC-157 reconstitution calculator.
BPC-157 arrives as a 5 mg or 10 mg lyophilized vial, and almost every published concentration table assumes the 5 mg one. If you bought 10 mg and used a 5 mg table, every number you read is off by half.

Each unit on a 100u · 1.0 mL syringe ≈ 25 mcg of this solution.

More water → lower concentration → more units for the same amount.
What changes the math for BPC-157.
- 5 mg in 2 mL is 2,500 mcg/mL, so one U-100 unit carries 25 mcg. 10 mg in the same 2 mL doubles that to 50 mcg per unit.
- Small target amounts on a concentrated solution land in the bottom few units of the syringe, where the markings are hardest to read accurately. Adding more water moves the same amount further up the barrel.
- The powder is stable at room temperature before mixing. Once it is in bacteriostatic water it goes in the refrigerator, and the benzyl alcohol in the water is what makes the multi-week window possible at all.

BPC-157: research formats
Choose the format you are researching to see route-specific notes.
Most common research format. Stable in BAC water; no special diluent required.
BPC-157 is typically sold as a 5 mg lyophilized vial. Reconstituting with 2.0 mL BAC water gives 2,500 mcg/mL, a concentrated solution suitable for the small volumes used subcutaneously. The compound is stable in BAC water at refrigerator temperature for approximately 28–30 days.
A single 5 mg vial provides 10 injections at 500 mcg or 20 injections at 250 mcg. Plan reconstitution volume based on how quickly you will use the vial within 28–30 days.
FAQ.
How many units is 250 mcg of BPC-157?
It depends entirely on your concentration, which is why the question cannot be answered from the compound name alone. On a 5 mg vial in 2 mL (2,500 mcg/mL) it is 10 units. On the same vial in 5 mL it is 25 units. Enter your own vial and water above.
Does BPC-157 need bacteriostatic water specifically?
Sterile water dissolves it just as well, but it has no preservative, so a vial mixed with sterile water is single-session. Bacteriostatic water contains benzyl alcohol, which is what allows a mixed vial to be drawn from repeatedly over weeks.
How many draws will a 5 mg vial give me?
Total amount divided by amount per draw, and it does not change with water volume. 5 mg is 5,000 mcg, so at 250 mcg per draw that is 20 draws whether you mixed it in 1 mL or 5 mL. The calculator shows this figure directly.
