BPC-157 is dosed in micrograms out of a vial labelled in milligrams, and that single mismatch is where most of the confusion on this compound comes from. A 5 mg vial holds 5,000 mcg. Reconstituted with 2 mL that is 2,500 mcg/mL, so a 250 mcg dose is 0.1 mL, or 10 units. Reading the vial as 5 mcg instead of 5 mg would be a thousand-fold error. BPC-157 was removed from FDA Category 2 in April 2026 and remains under PCAC review; it is not currently compoundable and is sold for laboratory research.

How many units is 250 mcg of BPC-157?
10 units from a 5 mg vial reconstituted with 2 mL of bacteriostatic water, which is 2500 mcg/mL and makes 250 mcg a 0.1 mL draw. From the same vial with 1 mL it is 5 units, and from a 10 mg vial with 2 mL it is 5 units. Five units is a small mark to read accurately, which is the argument for the larger water volume.

Frequency, and how long a vial lasts
Commonly reported protocols sit at 250 to 500 mcg a day, sometimes split into two injections, run in blocks of four to eight weeks. At 250 mcg once daily a 5 mg vial is 20 days and a 10 mg vial is 40; at 500 mcg a day those halve to 10 and 20 days. Split dosing does not change the vial maths, only the size of each draw. This is a description of what gets reported, not a protocol anyone has licensed.
| Dose | Frequency | U-100 units (5 mg in 2 mL) | Per day | 5 mg vial lasts | 10 mg vial lasts |
|---|---|---|---|---|---|
| 250 mcg | once daily | 10 units | 250 mcg | 20 days | 40 days |
| 250 mcg | twice daily, 250 mcg each | 10 units each | 500 mcg | 10 days | 20 days |
| 500 mcg | once daily | 20 units | 500 mcg | 10 days | 20 days |
| 500 mcg | twice daily, 500 mcg each | 20 units each | 1000 mcg | 5 days | 10 days |
| 750 mcg | once daily | 30 units | 750 mcg | 6 days | 13 days |
| 1000 mcg | once daily | 40 units | 1000 mcg | 5 days | 10 days |
mg to mcg, so the vial makes sense
1 mg is 1,000 mcg. A 5 mg vial is 5,000 mcg and a 10 mg vial is 10,000 mcg. Every reported dose on this page is a fraction of a single milligram, which is why the vial lasts weeks. The table converts each way so the label and the dose are in the same units.
| Micrograms | Milligrams | Units, 5 mg in 2 mL | Units, 10 mg in 2 mL |
|---|---|---|---|
| 100 mcg | 0.1 mg | 4 | 2 |
| 250 mcg | 0.25 mg | 10 | 5 |
| 500 mcg | 0.5 mg | 20 | 10 |
| 750 mcg | 0.75 mg | 30 | 15 |
| 1000 mcg | 1 mg | 40 | 20 |
| 2000 mcg | 2 mg | 80 | 40 |
| 5000 mcg | 5 mg | 200 | 100 |
Common questions
- How many units is 250 mcg of BPC-157?
- 10 units from a 5 mg vial reconstituted with 2 mL of bacteriostatic water, which is 2,500 mcg/mL. From the same vial with 1 mL it is 5 units, and from a 10 mg vial with 2 mL it is 5 units.
- How many mcg are in a 5 mg BPC-157 vial?
- 5,000 mcg. 1 mg is 1,000 mcg. At 250 mcg a day that vial is 20 doses; at 500 mcg a day it is 10.
- How much bacteriostatic water for a 5 mg BPC-157 vial?
- 2 mL is the usual choice and gives 2,500 mcg/mL, which puts the commonly reported 250 to 500 mcg range at 10 to 20 units. With 1 mL the same range is 5 to 10 units, where a single misread mark is a large proportional error.
- How often is BPC-157 injected?
- Reports describe once or twice daily, in blocks of four to eight weeks. Splitting the same daily amount into two injections does not change how long the vial lasts, only the size of each draw.
- What is the regulatory status of BPC-157?
- It was removed from FDA Category 2 in April 2026 and remains under review by the Pharmacy Compounding Advisory Committee. It is not currently compoundable, is not an approved medicine in any major market, and is sold for laboratory research.
