BPC-157 calculator — reconstitution & syringe units
Use this BPC-157 (BPC 157) measurement calculator when you already have a vial size, a water volume, and a target amount from an authorized source. PepExact returns concentration, draw volume, and U-100 syringe units — with the math shown. It does not choose a dose or protocol.
The fields below are generic example numbers, filled in so you can see the calculator work — they are not a recommended BPC-157 dose. Clear them and enter your own vial size, water, and dose from an authorized source.

- 1. Concentration: 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL)
- 2. Volume for one dose: 250 mcg ÷ 2,500 mcg/mL = 0.1 mL
- 3. Syringe units (U-100): 0.1 mL × 100 units/mL = 10 units
- 4. Doses in the vial: 5,000 mcg ÷ 250 mcg = 20 full doses

What this BPC-157 calculator does
The compound name does not change the arithmetic. BPC-157 reconstitution math is the same three steps as any other peptide on PepExact: concentration from vial ÷ water, draw volume from dose ÷ concentration, then U-100 units from volume × 100.
BPC-157 vials are commonly labelled in milligrams — for example 5 mg or 10 mg — while individual amounts are often discussed in micrograms. Enter whatever your vial and dose labels actually say; keep mg and mcg distinct (1 mg = 1,000 mcg).
Whatever the compound, this page only does arithmetic. It turns a vial size in milligrams, the water you add in millilitres, and a dose into the number of units on a U-100 insulin syringe — and shows every step. It does not know, store, or suggest what any dose should be.
What BPC-157 is (identity, not advice)
BPC-157 (also written BPC 157, sometimes expanded as “Body Protection Compound-157”) is a synthetic peptide sequence that appears in laboratory and animal research literature indexed on PubMed.
PepExact does not claim that BPC-157 treats, cures, or prevents any condition. This page exists so measurement arithmetic — vial, water, and a user-supplied amount — can be checked transparently.
Searches for a “BPC 157 calculator” usually mean converting labelled milligrams and a chosen water volume into U-100 syringe marks. That conversion is what this tool calculates.
Research context (primary sources only)
Published preclinical papers discuss BPC-157 in a range of experimental models. Those papers are not dosing instructions, and this site does not summarise them as medical guidance. Use the PubMed search below to read primary literature.
Regulatory status varies by country and presentation. PepExact does not determine legality or approval. See the FDA, MHRA, and TGA links on the peptide regulators guide when you need an authoritative government source.

Common questions
How do I calculate BPC 157 syringe units after reconstitution?
Concentration is vial milligrams ÷ water millilitres; volume is your dose ÷ that concentration; units are volume in mL × 100 on a U-100 insulin syringe. PepExact runs all three steps and shows the working so you can check it.
Does the name BPC-157 change the calculation?
No. PepExact uses the same engine for every compound page. Only the heading and educational context change; the formulas stay identical.
Why does BPC-157 math mix mg and mcg?
Vials are usually labelled in mg; many target amounts are written in mcg. 1 mg equals 1,000 mcg. If those units are swapped, the result is off by a thousand. PepExact keeps both units visible in the working.
How much water should I use to reconstitute BPC-157?
The water volume is your choice and only changes the concentration, not how much peptide is in the vial. More water gives larger, easier-to-read draws; less water gives smaller ones. The reconstitution calculator solves for the water volume that lands a dose on a round number of units. PepExact does not recommend a water volume.
Why do BPC-157 unit counts differ between calculators?
Usually different assumptions about water volume, syringe type, or a mix-up between mg and mcg. Because PepExact shows every step, you can see exactly which number drove the result rather than trusting it blindly.
Does PepExact tell me how much BPC-157 to take?
No. It is a measurement calculator only. It converts a vial, a water volume, and a dose you already have into syringe units, and never recommends a dose.
