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.

BPC-157 dosage chart: units for 5 mg and 10 mg vials
BPC-157 dosage charts list doses in micrograms. The amounts most often cited in community protocols sit between 200 and 500 mcg, taken once or twice a day over a block of four to six weeks. Those figures are extrapolated from animal research rather than taken from an approved label (human trial data are limited), so this page does not recommend one. The chart shows what each commonly cited amount looks like on a U-100 syringe for the three most common vial set-ups.
Read across a row to see how much the vial and water change the draw. The same 250 mcg dose is 10 units from a 5 mg vial in 2 mL, 7.5 units from a 10 mg vial in 3 mL and 5 units from a 10 mg vial in 2 mL — which is why a dosage chart only helps once you know your own concentration.
- 5 mg + 2 mL (2,500 mcg/mL): 250 mcg = 10 units · 500 mcg = 20 units
- 10 mg + 2 mL (5,000 mcg/mL): 250 mcg = 5 units · 500 mcg = 10 units
- A 5 mg vial holds twenty 250 mcg doses — about ten days at twice a day

Educational reference only — not a dose recommendation. Units assume a U-100 insulin syringe (100 units = 1 mL on U-100); “per vial” is how many of that dose the vial holds, before the small dead-space loss on each draw. Confirm against your own vial label, 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
BPC-157 10 mg vial: units per dose (2 mL BAC water)
U-100 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 |
|---|---|---|---|---|
| 10 mg | 5 mg/mL | 4 u(0.04 mL) | 5 u(0.05 mL) | 10 u(0.1 mL) |

BPC-157 dose in units and mL
"Units" and "mL" describe the same draw two ways. mL is the actual volume of liquid; units are just the U-100 syringe scale, where 100 units = 1 mL. So once you know the mL, the units are simply mL × 100 — there is no separate conversion for the peptide itself.
The catch is that the same microgram dose is a different number of units at every concentration. A 250 mcg dose is 10 units in a 5 mg / 2 mL vial (2,500 mcg/mL) but only 5 units in a 5 mg / 1 mL vial (5,000 mcg/mL). Always read units off your own reconstitution, not a generic chart.
- U-100 units = draw volume in mL × 100
- 250 mcg at 2,500 mcg/mL = 0.10 mL = 10 units
- 250 mcg at 5,000 mcg/mL = 0.05 mL = 5 units
- 500 mcg at 2,500 mcg/mL = 0.20 mL = 20 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.
BPC-157 + TB-500 blend vials
A pre-mixed BPC-157 + TB-500 vial (the "Wolverine" blend, usually 5 mg + 5 mg) is calculated from the vial's total, not the BPC-157 share. 10 mg in 2 mL is 5 mg/mL of blend, so 500 mcg of blend — 250 mcg of each peptide — is 10 units.
