BPC-157 comes as lyophilized powder. You add bacteriostatic water to make it injectable. The math takes 30 seconds. Getting it wrong means every dose is off. Here is exactly how to do it.
Most people running BPC-157 use a 5mg vial at 250mcg twice daily. That is the setup this guide assumes. If your dose or vial size differs, use the reconstitution calculator for your exact numbers.
| Vial size | 5mg (5,000mcg) |
| BAC water added | 2mL |
| Concentration | 2,500 mcg/mL |
| Dose | 250mcg |
| Draw units | 10 units on U-100 syringe |
| Doses per vial | 20 doses |
| Days supply (2x daily) | 10 days |

BPC-157 vial. Bacteriostatic water (BAC water — not sterile water, not normal saline). A 1mL or 3mL drawing syringe. Alcohol swabs. Clean surface. The BAC water must be bacteriostatic, not plain sterile water — benzyl alcohol is what prevents bacterial growth across multiple draws.
Wipe the stopper of the BPC-157 vial and the BAC water vial with a fresh alcohol swab each. Let them dry for 10-15 seconds. Do not blow on them or touch the center after swabbing.
Draw 2mL of bacteriostatic water into your drawing syringe. Insert the needle into the BAC water vial at an angle, pull the plunger slowly to avoid air bubbles.
Insert the needle into the BPC-157 vial. Tilt the vial so the needle tip touches the glass wall. Release the BAC water slowly down the side — not directly onto the powder. Forcing water directly onto lyophilized powder can degrade the peptide. Let gravity and capillary action do the work.
Gently swirl the vial in a circular motion until the powder fully dissolves. The solution should be clear and colorless. Do not shake — shaking can break peptide bonds. If you see particles after 2-3 minutes of swirling, continue slowly. Most BPC-157 dissolves in 30-60 seconds.
Label the vial with the date reconstituted, BAC water volume, and concentration. Store at 2-8°C (standard refrigerator temperature). Reconstituted BPC-157 in BAC water is stable for 28-30 days refrigerated. Do not freeze a reconstituted vial.
| Dose | Draw (at 2,500 mcg/mL) | Draw (at 1,250 mcg/mL with 4mL BAC water) |
|---|---|---|
| 100mcg | 4 units | 8 units |
| 250mcg | 10 units | 20 units |
| 500mcg | 20 units | 40 units |
| 1mg | 40 units | 80 units |
All values for U-100 insulin syringe (100 units = 1mL). If your draw at 2mL BAC water is below 5 units, add more BAC water to improve accuracy. Use Custom Draw mode to specify exactly how many units you want per dose.
BPC-157 is typically injected subcutaneously (into fat tissue, not muscle). Most people inject in the abdomen, rotating sites to avoid tissue buildup. For injury-specific use, some protocols call for intramuscular injection near the affected area — this is a clinical decision, not a calculator one.
Use a 28-31 gauge insulin syringe for subcutaneous injection. Pinch a small fold of skin, insert at 45°, release the skin, inject slowly.
Any vial size, any dose, any BAC water amount. Custom Draw mode included.
