BPC-157 reconstitution chart: units to draw by vial size and BAC water
Find the row for the mg on your vial and the water you added. Amounts are the 200 to 500 mcg range on our BPC-157 page, plus the 250 mcg typical figure in our calculator. Units are on a U-100 insulin syringe, where 100 units is 1 mL.
| Vial | BAC water | Strength | Units to draw for | ||
|---|---|---|---|---|---|
| 200 mcg | 250 mcg | 500 mcg | |||
| 2 mg | 1 mL | 2 mg/mL | 10 | 12.5 | 25 |
| 2 mL | 1 mg/mL | 20 | 25 | 50 | |
| 3 mL | 0.67 mg/mL | 30 | 37.5 | 75 | |
| 5 mg | 1 mL | 5 mg/mL | 4 | 5 | 10 |
| 2 mL | 2.5 mg/mL | 8 | 10 | 20 | |
| 3 mL | 1.67 mg/mL | 12 | 15 | 30 | |
| 10 mg | 1 mL | 10 mg/mL | 2 | 2.5 | 5 |
| 2 mL | 5 mg/mL | 4 | 5 | 10 | |
| 3 mL | 3.33 mg/mL | 6 | 7.5 | 15 | |
* Over 100 units: more than a 1 mL syringe holds in one draw. † Under 2 units: hard to measure; more water makes the draw bigger. Arithmetic from the numbers in each row. Pepdex does not pick a dose for you.
What to know about BPC-157 before you mix it
BPC-157 is a synthetic 15-amino-acid peptide derived from a protective stomach protein, studied for tendon, ligament and gut repair.
- How it is supplied
- There is no approved BPC-157 product. It comes as freeze-dried powder and is mixed by the user. Oral capsules are sold too; they are a different product and this calculator does not apply to them.
- Common vial sizes
- 5 mg, 10 mg. Work from the mg printed on your own vial.
- Half-life
- Listed as about 4 hours after a sub-q shot, without solid human data behind it. Most of what is known comes from animal studies.
- Usual schedule on our page
- Daily.
- FDA status
- Not FDA approved for any indication.
- Evidence in one line
- 0 completed human efficacy trials. Source: FDA's 2026 review found the available human material does not support effectiveness; the animal literature is extensive.
What people track with BPC-157
- Daily shot time and the spot you injected
- The injury you are watching, rated 1 to 10 each week
- Start and stop dates, since our page describes 4 to 6 week cycles
The common BPC-157 mix-up
mcg versus mg. BPC-157 amounts are written in mcg and vials in mg. 250 mcg is 0.25 mg: from a 5 mg vial mixed with 2 mL that is 10 units, not 1.

How long a BPC-157 vial lasts
A 10 mg vial at 250 mcg a shot holds 40 shots. Taken once a day, that is about 40 days (5.7 weeks). Shots per vial for each size:
| Vial | At 200 mcg | At 250 mcg | At 500 mcg |
|---|---|---|---|
| 2 mg | 10 shots | 8 shots | 4 shots |
| 5 mg | 25 shots | 20 shots | 10 shots |
| 10 mg | 50 shots | 40 shots | 20 shots |
BPC-157 reconstitution questions
- How much BAC water (reconstitution solution) do I add to a 10 mg BPC-157 vial?
- Any amount works for the math; it only changes the strength. 10 mg in 1 mL is 10 mg/mL, in 2 mL 5 mg/mL, and in 3 mL 3.33 mg/mL. More water gives a bigger draw that is easier to read. If your product came with mixing directions, those set the volume.
- How many units is 250 mcg of BPC-157?
- It depends on how much water is in the vial. From a 10 mg vial mixed with 2 mL, 250 mcg is 5 units (0.05 mL). With 1 mL it is 2.5 units; with 3 mL, 7.5 units.
- How many 250 mcg doses are in a 10 mg BPC-157 vial?
- 40. Taken once a day, that lasts about 40 days (5.7 weeks). The water you add does not change the count, only the size of each draw.
- Is BPC-157 the same as TB-500?
- No. BPC-157 is a gastric pentadecapeptide studied largely for local tissue and the gut; TB-500 is a Thymosin Beta-4 fragment studied for broader cell migration. Different molecules, and a dose of one is not a dose of the other.
