Quick math example
A 5 mg vial mixed with 2 mL gives 2,500 mcg/mL. A 250 mcg dose is 0.1 mL, or 10 units on a U-100 syringe.
Reconstitution reference
U100 units to draw for each common BPC-157 dose, by vial size, reconstituted with 2 mL of bacteriostatic water. Change the water volume in the calculator above to recompute for your own setup.
| Vial | Concentration | 200 mcg | 250 mcg | 500 mcg |
|---|---|---|---|---|
| 5 mg | 2.5 mg/mL | 8 u(0.08 mL) | 10 u(0.1 mL) | 20 u(0.2 mL) |
| 10 mg | 5 mg/mL | 4 u(0.04 mL) | 5 u(0.05 mL) | 10 u(0.1 mL) |
Educational reference only — not a dose recommendation. Units assume a U100 insulin syringe (100 units = 1 mL on U-100). Always confirm against your own vial, diluent, and clinician or pharmacy instructions.
How the BPC-157 calculation works
BPC-157 is commonly labeled in milligrams per vial while target amounts are often discussed in micrograms. The calculator keeps those unit conversions explicit.
Once concentration is known, every dose is just target mcg divided by mcg per mL.
- 5 mg vial = 5,000 mcg total
- 2 mL water = 2,500 mcg per mL
- 250 mcg target = 0.1 mL draw
BPC-157 5 mg vial with 2 mL example
A 5 mg BPC-157 vial contains 5,000 mcg. Mixed with 2 mL, that gives 2,500 mcg/mL.
A 250 mcg target dose is 0.1 mL at this concentration. On a U-100 syringe, 0.1 mL equals 10 units.
- 5 mg = 5,000 mcg
- 5,000 mcg / 2 mL = 2,500 mcg/mL
- 250 mcg / 2,500 mcg per mL = 0.1 mL = 10 U-100 units
BPC-157 10 mg vial with 2 mL example
A 10 mg BPC-157 vial contains 10,000 mcg. Mixed with 2 mL, that gives 5,000 mcg/mL.
A 500 mcg target dose is 0.1 mL at this concentration, which equals 10 units on a U-100 syringe.
- 10 mg = 10,000 mcg
- 10,000 mcg / 2 mL = 5,000 mcg/mL
- 500 mcg / 5,000 mcg per mL = 0.1 mL = 10 U-100 units
Protocol tracking matters for short cycles
Recovery-focused protocols can involve daily or near-daily schedules. Saving the calculated draw amount, reconstitution date, and doses remaining can reduce repeated manual math.
