BPC-157 Dosage Calculator

BPC-157 is almost always sold as a 5 mg or 10 mg lyophilised vial, and typical doses are in the 250–500 mcg range — small enough that reconstitution volume matters a lot. Enter your numbers below to get the exact units to draw.

This is a unit converter. It converts an amount you already have into volume and syringe units. It does not tell you what to take, and it is educational only — not medical advice. Confirm every amount with your clinician and your product label.

BPC-157 dosing at a glance

Phase	Dose	Frequency	Notes
Common low	200–250 mcg	Once or twice daily	Most-used range in anecdotal protocols.
Common standard	250–500 mcg	Once or twice daily	Often split morning and evening.
Localised use	250–500 mcg	Daily near the site	Subcutaneous near the injury area is common practice.
Typical cycle	—	4–8 weeks	Then a break; long-term human safety data does not exist.

What trips people up

BPC-157 has no completed human efficacy trials. All dosing conventions are extrapolated from rodent studies and user reports.
5 mg + 2 mL = 2.5 mg/mL, so 250 mcg = 10 units on a U-100 syringe — the single most common BPC-157 setup.
If your draw comes out under 5 units, add more BAC water. Measuring 3 units accurately on a U-100 syringe is unrealistic.
Blends with TB-500 change the maths entirely — calculate each peptide's mg separately, not the combined label weight.

How the maths works

Concentration (mg/mL) = vial mg ÷ bacteriostatic water mL.
Volume per dose (mL) = dose mg ÷ concentration.
Syringe units = volume × 100 on a U-100 syringe, or × 40 on a U-40 syringe.
Doses per vial = vial mg ÷ dose mg. Water volume never changes this number.

BPC-157 calculator FAQ

How much BAC water for a 5 mg BPC-157 vial?

2 mL is standard, giving 2.5 mg/mL where 250 mcg = 10 units and 500 mcg = 20 units on a U-100 syringe. Use 5 mL if you want 1 mg/mL and very readable 25-unit draws for a 250 mcg dose.

How many units is 250 mcg of BPC-157?

At the standard 5 mg + 2 mL (2.5 mg/mL), 250 mcg is 0.1 mL = 10 units on a U-100 syringe. At 5 mg + 5 mL (1 mg/mL) the same dose is 25 units.

How many doses are in a 5 mg BPC-157 vial?

At 250 mcg per dose, a 5 mg vial holds 20 doses. At 500 mcg, 10 doses. Reconstitution volume does not change this — only the dose size does.

Does BPC-157 need to be refrigerated after mixing?

Yes. Reconstituted BPC-157 should be kept at 2–8 °C and protected from light. Unreconstituted lyophilised powder is far more stable and can sit at room temperature for shorter periods.
