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 10 mg vial 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 |
|---|---|---|---|---|
| 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.
10 mg BPC-157 vial examples
A 10 mg vial in 2 mL gives 5 mg/mL (5,000 mcg/mL). A 500 mcg dose is 0.1 mL, which equals 10 units on a U-100 syringe; a 250 mcg dose is 0.05 mL, or 5 units.
Reconstituting the same vial in 1 mL gives 10 mg/mL, halving each draw — a 250 mcg dose becomes just 2-3 units, which can be harder to measure accurately.
- 10 mg / 2 mL = 5 mg/mL → 500 mcg = 0.1 mL = 10 units
- 10 mg / 2 mL = 5 mg/mL → 250 mcg = 0.05 mL = 5 units
- A 10 mg vial holds about 40 doses at 250 mcg, or 20 at 500 mcg
The 10 mg vial for longer BPC-157 cycles
BPC-157 is often run daily, so a 10 mg vial — double the common 5 mg size — covers a longer cycle from one reconstitution. At 250 mcg per day it lasts well over a month, which makes the reconstitution date and beyond-use date worth tracking.
More peptide per vial also means choosing a water volume that keeps daily draws readable: 2 mL keeps a 250 mcg dose at a measurable 5 units, where 1 mL would shrink it to 2-3 units.
- Daily dosing: a 10 mg vial spans a long cycle
- 2 mL keeps small daily draws on readable unit marks
- Track the reconstitution and beyond-use dates across the cycle
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 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.
