BPC-157 Dosage Calculator

BPC-157 is supplied in 5 mg and 10 mg lyophilised vials. Because typical research draws are in the low hundreds of micrograms, most protocols reconstitute with 2-3 mL so the draw volume is large enough to measure accurately.

The formula

Concentration (mg/mL) = vial strength (mg) ÷ bacteriostatic water (mL). Draw volume (mL) = dose (mg) ÷ concentration (mg/mL). On a U-100 insulin syringe, units = draw volume (mL) × 100. For BPC-157: a 5 mg vial in 2 mL of water is 2.5 mg/mL, so a 250 mcg dose is 0.1 mL — 10 units.

How to reconstitute a BPC-157 vial

  1. 1. Bring the vial to room temperature. Let a refrigerated or frozen vial equilibrate before opening so condensation doesn't form on the powder.
  2. 2. Swab both stoppers. Wipe the BPC-157 vial and the bacteriostatic water vial with alcohol and let them dry.
  3. 3. Draw your diluent. Pull the volume you entered above into the syringe.
  4. 4. Run it down the glass wall. Angle the needle so water flows down the side of the vial rather than jetting onto the peptide cake — shear and foaming degrade peptides.
  5. 5. Swirl, never shake. Roll the vial gently until fully clear. Do not vortex or shake.
  6. 6. Label and refrigerate. Mark the date and concentration, then store at 2-8 °C away from light.

BPC-157 calculator FAQs

How many units is 250 mcg of BPC-157 from a 5 mg vial?

5 mg with 2 mL of bacteriostatic water is 2.5 mg/mL. A 250 mcg draw is 0.1 mL — 10 units on a U-100 insulin syringe, and the vial contains 20 draws.

How long does reconstituted BPC-157 last?

Once mixed with bacteriostatic water, BPC-157 is stored at 2-8 °C, protected from light, and is generally handled within about 3-4 weeks. Unreconstituted vials are far more stable and are usually kept frozen.

How do you calculate a BPC-157 dose in syringe units?

Divide the vial strength by the bacteriostatic water you added to get the concentration: concentration (mg/mL) = vial mg ÷ water mL. Then draw volume (mL) = dose (mg) ÷ concentration. On a U-100 insulin syringe, 1.0 mL is 100 units, so units = draw volume × 100.

Does adding more water change how much BPC-157 is in the vial?

No. The vial holds a fixed mass of lyophilised powder. More bacteriostatic water only dilutes it — each syringe unit carries less compound and the draw volume for the same dose gets larger, which can make small doses easier to measure accurately.

How is reconstituted BPC-157 stored?

After reconstitution with bacteriostatic water, research peptides are kept refrigerated at 2-8 °C, protected from light, and away from freeze-thaw cycles. Unreconstituted lyophilised vials are far more stable and are typically stored frozen.
