Units shown for a U-100 insulin syringe (1 mL = 100 units). No rounding · the full math is above.

How the math works

Three steps, no hand-waving.

Reconstitution is simple arithmetic. The only thing that matters is that it is exact, and that you can see every step.

1 · Concentration

Vial mg ÷ BAC water mL = mg/mL. A 5 mg vial in 2 mL of water is 2.5000 mg/mL.

2 · Draw volume

Target dose ÷ concentration = mL to draw. 250 mcg ÷ 2.5000 mg/mL = 0.1000 mL.

3 · Syringe units

Draw mL × 100 = units on a U-100 insulin syringe. 0.1000 mL = 10 units.

Background

What BPC-157 reconstitution is

BPC-157 is a research peptide supplied as a lyophilized powder that must be reconstituted with bacteriostatic water before a dose can be drawn. Concentration is simply the mg in the vial divided by the mL of water you add. Because typical doses are in the low microgram-to-milligram range, small rounding errors matter. This calculator shows every decimal so the draw is exact.

In the Regimio app
  • Reconstitution built into the dose logger, not a separate tool
  • 28-day BAC water expiry countdown per vial
  • Doses remaining and refill warnings, all derived
  • Local-first · no account, data stays on your device

FAQ

BPC-157 reconstitution questions, answered.

How do you calculate a BPC-157 dose?

Divide the mg of BPC-157 in the vial by the mL of bacteriostatic water you add to get the concentration in mg/mL. Then divide your target dose (converted to mg) by that concentration for the draw volume in mL. Multiply by 100 for units on a U-100 insulin syringe.

How much BAC water for a 5mg BPC-157 vial?

There is no single right answer. 2 mL gives 2.5 mg/mL; 1 mL gives 5 mg/mL and a smaller draw. Enter the amount you plan to add and the calculator shows your exact draw volume and units for any target dose.

How many units is 250 mcg of BPC-157?

It depends on the concentration. At 2.5 mg/mL (a 5 mg vial in 2 mL), 250 mcg is 0.1000 mL, or 10 units on a U-100 syringe. Change any input above to see your own numbers.

How do I convert BPC-157 mcg to mg?

1 mg equals 1000 mcg, so a 250 mcg dose is 0.25 mg. Enter your dose in whichever unit your protocol uses and the calculator converts before solving, so both return the same draw.

Is BPC-157 FDA approved?

No. BPC-157 is a research peptide and is not approved by the FDA for any use. The FDA flagged it as unsuitable for compounding in 2023, then pulled it back for re-review ahead of a July 2026 advisory committee meeting. This tool is arithmetic only, not a recommendation to use it. See our 'are peptides legal' explainer for the regulatory picture.

Is BPC-157 banned in sports?

Yes. The World Anti-Doping Agency Prohibited List bans BPC-157 at all times, in and out of competition, for tested athletes. Anti-doping rules apply strict liability: what is in your sample is your responsibility regardless of how a product was labeled.

How should reconstituted BPC-157 be stored?

Follow the storage guidance for your specific product. Reconstituted peptide vials are generally refrigerated and used within a limited window. Regimio tracks a per-vial expiry countdown so you are not guessing how many days are left.

Is this medical advice?

No. This is a calculator that performs arithmetic on the values you enter. It does not recommend a dose, schedule, or source. Confirm anything you do with a qualified provider.
