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.
Frequently asked questions Is BPC-157 approved as a medicine?+
Around 2023-2025 the US FDA moved BPC-157 into a bulk-substances category that effectively restricts compounding-pharmacy use, and it is not an approved human medicine in most other markets either. This page only explains the calculator math and makes no treatment recommendation. Can I calculate a BPC-157 and TB-500 stack?+
Yes — calculate each compound on its own page so the per-draw volume stays separate, then track the two schedules side by side. PepSync's stack view compares vial setups without combining their concentration math. What if my BPC-157 vial uses a different water amount?+
Enter your actual bacteriostatic water volume. A 5 mg vial in 1 mL is 5,000 mcg/mL (a 250 mcg dose = 5 units), while the same vial in 2 mL is 2,500 mcg/mL (250 mcg = 10 units) — the dose is identical, only the units on the syringe change. How many BPC-157 doses are in a 5 mg vial?+
Divide the vial total by your per-dose amount. A 5 mg (5,000 mcg) vial dosed at 250 mcg gives 20 doses; at 500 mcg it gives 10. PepSync counts the remaining doses down as you log each injection.
