How to use this BPC-157 calculator

  1. Enter the vial size printed on your label — BPC-157 is commonly sold as 5 mg, 10 mg.
  2. Enter the bacteriostatic water you added, in mL.
  3. Enter your dose, in mcg.
  4. Pick your syringe — the units, fill bar and warnings all adjust to it.

Worked example

A 10 mg BPC-157 vial reconstituted with 2 mL of bacteriostatic water gives a concentration of 5 mg/mL. A 250 mcg dose is 0.05 mL — which is 5 units on a U-100 insulin syringe, and about 40 doses per vial.

The calculator above is already loaded with these numbers. Change any field to match your own vial.

Typical range (research)
Commonly referenced in literature around 200–500 mcg per day, sometimes split into two administrations (research reference only)
Half-life
~4 hours (short; commonly cited as rapidly cleared)
Route
Subcutaneous or intramuscular (research)
Common vial sizes
5 mg · 10 mg
Storage
Lyophilized powder stored refrigerated or frozen and protected from light; once reconstituted, kept refrigerated (2–8 °C) and used within several weeks

Common questions

How many units is 250 mcg of BPC-157?

On a 10 mg vial reconstituted with 2 mL (5 mg/mL), 250 mcg is 0.05 mL — 5 units on a U-100 insulin syringe. Because BPC-157 amounts are referenced in micrograms while vials are labelled in milligrams, the mcg → mg conversion (÷ 1000) is where most arithmetic mistakes happen. The calculator handles it.

Why are BPC-157 amounts so small compared with GLP-1 peptides?

It's simply a different scale. BPC-157 is referenced in micrograms (thousandths of a milligram), so a 10 mg vial contains a large number of research-referenced doses — often dozens — where a GLP-1 vial might contain only a few.

How long does reconstituted BPC-157 last?

Once reconstituted, research sources commonly cite refrigeration at 2–8°C with use within roughly 30 days; lyophilised (powder) vials keep far longer. Storage guidance for each peptide is in the library profile.

Dose figures are ranges commonly referenced in research literature — not recommendations or medical advice. Arithmetic uses the values entered; it does not determine a suitable dose or verify your inputs. Research-only labeling does not establish that a substance is safe, approved or appropriate for personal use.
