BPC-157 Reconstitution & Dosage Calculator

BPC-157 vials vary by supplier and label amount. Enter the exact amount printed on your vial — not an example — along with the bacteriostatic water you added and the dose you already have, to get a concentration and syringe draw. This tool doubles as a BPC-157 dosage calculator — reconstitution and dosage are just two steps of the same math.

BPC-157 vials are commonly sold in 5 mg and 10 mg sizes. Enter your vial's actual labeled amount, not one of these examples.

How this calculator works

Concentration = peptide amount ÷ bacteriostatic water volume.
Injection volume = your dose ÷ that concentration.
Syringe units = injection volume × 100, since a U-100 syringe holds 100 units per mL.

How much bacteriostatic water for BPC-157?

Your BPC-157 vial doesn't have a required water volume — whatever you pour in becomes the denominator that sets concentration. A smaller pour concentrates the same BPC-157 mass, shrinking the draw for any dose; a larger pour dilutes it, growing the draw. Add your BPC-157 vial's mg and chosen water volume above to see which you get.

BPC-157 units calculator

A U-100 syringe barrel is printed with unit lines, 100 to a milliliter, and that's the scale your BPC-157 draw needs to match. This calculator turns the injection volume from your BPC-157 concentration and dose into that same unit count, so you're reading a BPC-157 draw off printed lines rather than judging a fraction of a milliliter by eye.

BPC-157 TB-500 blend dosage calculator

A BPC-157/TB-500 blend vial holds two peptides in one solution, but each still needs its own concentration and dose — there's no single combined number. Read each compound's labeled amount separately (for example, 5 mg BPC-157 and 5 mg TB-500 in the same vial); both dissolve into the same water volume when you reconstitute. Run this calculator once per compound, entering that compound's labeled amount with the total water volume you added, to get its individual concentration and syringe draw.

Frequently asked questions

Is this a BPC-157 dosage calculator?

Yes. Reconstitution and dosage are two steps of the same calculation: this tool first works out your BPC-157 vial's concentration from its amount and water volume, then — once you enter a dose — converts that dose into an injection volume and syringe unit count.

How do I calculate BPC-157 dosage after reconstitution?

Once your BPC-157 vial is reconstituted, its concentration is fixed at the peptide amount divided by the water volume you added. Divide your dose by that concentration to get the injection volume, then multiply by 100 to read it in units on a U-100 syringe.

What size are BPC-157 vials?

BPC-157 vials are commonly sold in 5 mg and 10 mg sizes, but always use the exact amount printed on your own vial's label rather than one of these examples — label amounts vary by supplier.

Does this work for a 10 mg BPC-157 vial?

Yes — enter 10 mg as the peptide amount (or 10,000 mcg, using the unit toggle) along with the exact water volume you added. 5 mg and 10 mg are just the two most common label sizes; the calculator works identically for either, or for any other amount printed on your vial.

Is there a BPC-157 peptide dosing chart?

See the mg/mcg and mL/units conversion chart below. It converts between units only — it does not list a recommended BPC-157 dose, which should come from your own prescription or protocol.

Does BPC-157 dosage use mg or mcg?

Both units appear on different suppliers' labels and protocols. 1 mg = 1,000 mcg. The calculator above has an mg/mcg toggle for both the vial amount and the dose field — match whichever unit is printed on your paperwork.

Is this BPC-157 calculator medical advice?

No. It applies one formula — mass divided by volume, then dose divided by concentration — to the numbers you enter. It does not suggest a dose, a vial size, or a solution volume. See the medical disclaimer for full detail.
