BPC-157 Dosage Calculator
Enter the amount in your BPC-157 vial, the volume it is in, and the dose you want expressed in syringe units. This page computes the arithmetic of those values — concentration, the volume to draw, insulin-syringe units, and doses per vial. It is not a dosing recommendation.

- Regulatory status
- There is no FDA-approved product containing this compound in any form, and it is not an approved medicine in the United States. Material sold for laboratory or research use is not labeled or regulated for human use, and no approved labeling defines a vial strength, a diluent, or a concentration for it.
What BPC-157 is
BPC-157 is a synthetic pentadecapeptide — a chain of 15 amino acids, sequence GEPPPGKPADDAGLV, corresponding to a partial sequence of a protein fragment identified in human gastric juice.
There is no FDA-approved BPC-157 product, so no approved labeling defines a vial strength, a diluent, or a concentration for it, and what a given vial contains is only what is printed on that vial.
Supplied as a lyophilized (freeze-dried) powder, it has to be dissolved in a diluent before any volume can be drawn, and the resulting concentration depends only on the mass in the vial and the volume added.
This page's calculator computes that concentration, the volume to draw, and the equivalent insulin-syringe units from the numbers you enter.

Each link re-runs the calculator above with that strength's numbers already entered.
Rows marked FDA-approved are strengths stated in approved labeling. Rows marked commonly supplied are vial sizes that compounded and research presentations are commonly supplied in; no approved labeling defines those, and what a given vial contains is only what is printed on that vial.
BPC-157 calculator questions
How many units is a 250 mcg dose of BPC-157?
With the example values on this page — 5 mg in 2 mL of bacteriostatic water — the vial works out to 2.5 mg/mL, so a 250 mcg dose is 0.1 mL, which reads as 10 units on a U-100 insulin syringe. Change any field in the calculator above and the computed units change with it.
What does a 5 mg vial of BPC-157 come out to with different amounts of bacteriostatic water?
Concentration is the mass in the vial divided by the volume it is in, so changing only the volume changes every downstream number: 1 mL computes to 5 mg/mL, making a 250 mcg dose 0.05 mL (5 units); 2 mL computes to 2.5 mg/mL, making a 250 mcg dose 0.1 mL (10 units); 4 mL computes to 1.25 mg/mL, making a 250 mcg dose 0.2 mL (20 units). Each figure is arithmetic on the two values stated, not a statement that any of those volumes is the one to use.
How many 250 mcg doses are in a 5 mg vial of BPC-157?
Dividing 5 mg by 250 mcg computes to 20 full doses. Only whole doses are counted — any remainder smaller than a full dose is left out of that figure. Different vial contents or a different dose produce a different count; enter yours in the calculator above.
What concentration is 5 mg of BPC-157 in 2 mL?
5 mg in 2 mL computes to 2.5 mg/mL. From that concentration, the volume holding a 250 mcg dose is 0.1 mL, or 10 units on a U-100 syringe. This page reports that division; it does not evaluate the numbers you put into it.
How much bacteriostatic water do I add to a vial of BPC-157?
That volume is an input to this calculator, not an output of it — this page does not pick a volume for you and nothing here says which one to use. What it can tell you is what each choice computes to: 5 mg with 1 mL works out to 5 mg/mL, and the same 5 mg with 4 mL works out to 1.25 mg/mL. The mass in the vial never changes; only the concentration and the volume you would draw do.
