BPC-157 Reconstitution
How to mix BPC-157 and read the exact units to draw. Enter your vial size and bacteriostatic water below for the concentration and dose on a U-100 insulin syringe.
How to reconstitute BPC-157
- Swab the rubber stopper of the BPC-157 vial and the bacteriostatic water vial with an alcohol wipe.
- Draw your chosen volume of bacteriostatic water into a syringe (1 to 3 ml is common).
- Inject the water slowly down the inside wall of the BPC-157 vial, not directly onto the powder.
- Swirl gently until the powder fully dissolves. Do not shake. Shaking can damage the peptide.
- Refrigerate and use within about 4 to 6 weeks.
BPC-157 concentration by water volume
For a 5 mg vial, the concentration depends only on how much bacteriostatic water you add. More water lowers the concentration and makes small doses easier to measure.
| BAC water added | Concentration | Per 1 unit |
|---|---|---|
| 1 ml | 5,000 mcg/ml | 50 mcg |
| 2 ml | 2,500 mcg/ml | 25 mcg |
| 3 ml | 1,666.7 mcg/ml | 16.7 mcg |
BPC-157 units to draw
At 2,500 mcg/ml (a 5 mg vial in 2 ml of bacteriostatic water), here is the draw for common doses on a U-100 insulin syringe. Change any number in the calculator above for your own vial.
| Dose | Units to draw | Volume |
|---|---|---|
| 100 mcg | 4 units | 0.04 ml |
| 200 mcg | 8 units | 0.08 ml |
| 250 mcg | 10 units | 0.10 ml |
| 300 mcg | 12 units | 0.12 ml |
| 500 mcg | 20 units | 0.20 ml |
BPC-157 dosing
Preclinical and community protocols commonly reference 200-500 mcg/day subcutaneous, near the injury site or systemically; no established human clinical dose exists. Enter your own vial size, water volume, and target dose in the calculator above to convert any BPC-157 protocol into exact insulin-syringe units. For the full profile, see the BPC-157 compound page.
Storing reconstituted BPC-157
Once mixed, keep BPC-157 refrigerated at 2 to 8 degrees C and use it within about 4 to 6 weeks. Store unopened lyophilised powder in the freezer. Protect from light and avoid repeated freeze-thaw cycles, which degrade the peptide.
The math
- Concentration (mcg/ml) = vial size in mg × 1,000 ÷ bacteriostatic water in ml.
- Volume for your dose (ml) = dose in mcg ÷ concentration.
- Units to draw = volume in ml × 100 on a U-100 insulin syringe.

BPC-157 reconstitution FAQ
Draw bacteriostatic water into a syringe, inject it slowly down the inside wall of the BPC-157 vial, and swirl gently until the powder dissolves. Do not shake. The concentration is the vial size in mg times 1,000, divided by the millilitres of water you added.
There is no single correct amount. 1 to 3 ml per vial is common. More water makes small doses easier to measure. A 5 mg vial in 2 ml gives 2,500 mcg/ml. The calculator shows the concentration for any volume you choose.
Units to draw equals your dose in mcg divided by the concentration in mcg/ml, times 100 on a U-100 insulin syringe. At 2,500 mcg/ml, a 250 mcg dose is 10 units.
Keep reconstituted BPC-157 refrigerated at 2 to 8 degrees C and use it within about 4 to 6 weeks. Store the unopened lyophilised powder in the freezer. Protect from light and avoid repeated freeze-thaw.
