BPC-157 reconstitution calculator
Reconstitution calculator for BPC-157, prefilled for 5 mg and 10 mg vials. Work out the concentration, the dose volume in millilitres, and the reading on a U-100 insulin syringe.
Start from a compound
Fills the vial size and a starting water volume. Only compounds with a citable range fill a dose.
The second is the question asked once the syringe is already filled, or when checking a vial someone else reconstituted.
1 mg = 1,000 mcg. Published figures are usually micrograms; vial labels are milligrams.

BPC-157 — Animal data only — no human dosing study
Extrapolated from animal studies. No human dosing study exists for this compound, so this range is an inference, not a finding. The prefilled dose is the low end of that range, commonly split across the day in the cited protocols.
Vial size and water volume are a starting point for the arithmetic, not a recommendation.
Adding more water makes the same dose a larger, easier-to-read mark on the syringe. It does not change how many doses the vial holds.
Vial sizes and starting volume
BPC-157 is commonly supplied in 5 mg and 10 mg vials. The calculator opens on a 5 mg vial with 2 mL of bacteriostatic water — a starting point for the arithmetic, not a recommendation. Change either and everything recalculates.
That combination gives 2.5 mg/mL, so one insulin unit holds 25 mcg and a 200 mcg dose is 8 units.
Half-life, and why it matters here
Under 30 minutes after IM or IV administration in rodent and dog models. No human pharmacokinetic study has been published. A shorter half-life is why some protocols split a daily amount across more than one administration, which means more and smaller draws from the same vial — and a smaller draw is where a thinner dilution becomes harder to read accurately.

The half-life and clearance calculator works this through for a given dose.
What dose to enter
A range of 200–500 mcg per dose can be cited for BPC-157, commonly split across the day in the cited protocols. The dose field opens at the low end of it.

- Pharmacokinetics, distribution, metabolism, and excretion of body-protective compound 157 in rats and dogs — Peer-reviewed pharmacokinetics study. Establishes the short half-life the split-dose schedules are derived from — in rats and dogs, not humans.
- Safety of Intravenous Infusion of BPC157 in Humans: A Pilot Study — Human pilot study. The only human safety data located. It is intravenous and a pilot, so it does not establish a subcutaneous dose.
