BPC-157 Dosage Calculator
A synthetic peptide derived from a protein found in gastric juice, studied in the context of tissue repair.

Changes concentration only — your dose stays the same.
250 mcg = 0.25 mg
1 mL barrels are sold marked two ways: 0–100 insulin units (U-100) or 0–1 mL (tuberculin / luer). Same volume — 100 units = 1 mL — so the result below gives you both readings.
1.0 mL (100-unit) · top row = insulin units, bottom row = mL · smallest mark = 2 units · check yours, gradations vary by brand

- Concentration: 5 mg ÷ 2 mL = 2.50 mg/mL (2500 mcg/mL)
- Dose volume: 250 mcg ÷ 2500 mcg/mL = 0.100 mL
- Syringe units: 0.100 mL × 100 = 10 units
How much water should I add?
The same 250 mcg dose from your 5 mg vial, at each water volume. More water spreads the dose over more units, which is easier to read accurately. Tap a row to use it.
✓ = the draw lands exactly on a mark of your 1.0 mL (100-unit) syringe — no eyeballing between gradations.
Calculated on a U-100 insulin syringe (100 units = 1 mL). This is reconstitution arithmetic for BPC-157, not a dosing recommendation. Verify against your product label and a qualified professional.

About BPC-157 dosing
BPC-157 (BPC-157) is a synthetic peptide derived from a protein found in gastric juice, studied in the context of tissue repair. It is commonly sold in 5 mg, 10 mg vials. Commonly-cited community and research protocols reference a range of 200–500 mcg, once or twice daily in many cited protocols. Commonly reconstituted with 1–3 mL of bacteriostatic water per 5 mg vial. Refrigerate after mixing.
Remember that the number of syringe units for any dose depends entirely on how much bacteriostatic water you add. The calculator above is pre-filled with a common setup for BPC-157; adjust the inputs to match your own vial and the units update instantly.

BPC-157 calculator — FAQ
How do I reconstitute BPC-157?+
Commonly reconstituted with 1–3 mL of bacteriostatic water per 5 mg vial. Refrigerate after mixing. Add your chosen amount of bacteriostatic water to the vial, swirl gently (never shake), and use the calculator above to convert your target dose into insulin-syringe units.
What is a common BPC-157 dose?+
Commonly-cited protocols reference 200–500 mcg, once or twice daily in many cited protocols. These are references for the arithmetic, not a prescription — confirm with your product label and a qualified professional.
How many units of BPC-157 should I draw?+
That depends on your vial size and how much bacteriostatic water you added. Enter both into the calculator above along with your dose and it shows the exact units on a U-100 insulin syringe.
