BPC-157 dosage: what the research used
This page collects the doses reported in published BPC-157 research and works through the reconstitution maths for common vial sizes. It does not recommend any dose.
Doses used in published research
Almost all published doses are from rodents, typically:
- 10 µg/kg and 10 ng/kg body weight, given by intraperitoneal injection once daily, or
- similar per-kilogram amounts dissolved in drinking water (around 0.16 µg/mL).
There is no established human dose. Figures widely quoted online (for example 250–500 µg/day) come from community practice, not from trials.
BPC-157 reconstitution table
Syringe units (U-100: 100 units = 1 mL) needed for a given amount, by vial size and water volume:
| Vial | Water | Concentration | 100 µg | 250 µg | 500 µg |
|---|---|---|---|---|---|
| 5 mg | 1 mL | 5 mg/mL | 2 units | 5 units | 10 units |
| 5 mg | 2 mL | 2.5 mg/mL | 4 units | 10 units | 20 units |
| 5 mg | 3 mL | 1.667 mg/mL | 6 units | 15 units | 30 units |
| 10 mg | 1 mL | 10 mg/mL | 1 units | 2.5 units | 5 units |
| 10 mg | 2 mL | 5 mg/mL | 2 units | 5 units | 10 units |
| 10 mg | 3 mL | 3.333 mg/mL | 3 units | 7.5 units | 15 units |

Arithmetic aid for laboratory reconstitution. It does not recommend any amount for any use.
Handling and storage
Reconstitute with bacteriostatic water, adding it slowly down the vial wall and swirling rather than shaking — see the reconstitution guide. Once mixed, refrigerate at 2–8 °C; unmixed lyophilised powder keeps longest frozen (storage guide). Converting between units, mL and mg is covered in syringe units explained.
BPC-157 dosing FAQs
How much bacteriostatic water for a 5 mg BPC-157 vial?
There is no fixed amount — the volume sets the concentration. Adding 2 mL to a 5 mg vial gives 2.5 mg/mL; 1 mL gives 5 mg/mL, 2 mL gives 2.5 mg/mL, 3 mL gives 1.667 mg/mL.
How many units is 100 µg of BPC-157?
At 2.5 mg/mL (5 mg in 2 mL), 100 µg is 0.04 mL, or 4 units on a U-100 syringe. A different water volume changes this — use the calculator above.
Is there an approved BPC-157 dose?
no established human dose.
