BPC-157 Reconstitution Calculator

Enter your vial size and how much bacteriostatic water you'll add. The calculator gives you insulin-syringe units, mL per dose, total doses per vial, and (optional) cost per dose. No sign-up. Mobile-friendly.

Reading note. This is an arithmetic helper for users who already understand how peptide reconstitution works. It is not medical advice and does not validate that any dose is safe for you. BPC-157 is an unapproved research peptide. See our Methodology and Disclaimer.

Inputs

Most users add 1–3 mL. Adding less means each unit on the syringe = a larger dose; adding more means more precise small doses but smaller per-injection volume in absolute terms.
Reported dose ranges in user communities are 250–500 mcg per administration. We do not endorse a specific dose. See our dosage guide.
U-100 is standard. Pick the barrel size you actually have.

Sanity-check guidance. If your "units per dose" is below 2 or above the syringe's barrel capacity, redo the math with a different bacteriostatic-water volume — it'll be hard to draw accurately at extremes.

FAQ

What is reconstitution?

Peptides like BPC-157 ship as a freeze-dried powder. To use them as an injection, the powder is rehydrated with bacteriostatic water (sterile water with 0.9% benzyl alcohol added). The calculator converts your reconstitution choices into the practical numbers you actually need at injection time.

How much bacteriostatic water should I add?

1–3 mL is the common range. Less water concentrates the solution; more dilutes it. The trade-off is dose precision (more dilute = easier to measure small doses) versus injection volume.

What's an insulin syringe "unit"?

An insulin (U-100) syringe has 100 units per mL. So 10 units = 0.1 mL, 50 units = 0.5 mL.

Is this medical advice?

No. This is a math helper. We are not your clinician. BPC-157 is not FDA-approved. Discuss any health decision with a licensed clinician.

Where do I get a vial?

If you've decided to source one after consulting a clinician, our vendor reviews evaluate vendors on COA transparency, value, and reliability.
