BPC-157 dosage calculator
A reconstitution calculator preloaded with an example BPC-157 vial size. Enter your own vial mass, diluent, and dose to get concentration, draw volume, and insulin-syringe units. Arithmetic only - it does not tell you what dose to use.

Your vial
Printed on the vial. There is no standard size - enter what yours says.
This changes how much you draw - never how many doses the vial holds.
100 units per mL. 1 unit = 0.01 mL. This is what almost every insulin syringe sold is, in every barrel size.
Capacity only. A 1 mL U-100 syringe holds 100 units - the scale decides that, not the barrel.

What BPC-157 dosing actually looks like
BPC-157 has no approved product, so there is no approved dose. The protocol most often described by clinic and vendor dosing guides is 250-500 mcg by subcutaneous injection, once or twice daily, for a 4-8 week cycle with a 2-4 week break - common practice, not trial-established. The published human record is different: five small studies, about 80 people in all, used daily rectal enemas for one to two weeks or one or two injected doses of 2-20 mg, each by a route specific to that study. A rat tendon-healing study used a much smaller daily microgram-per-kilogram amount that cannot be converted into a human dose. None of those figures is a recommendation. Read the full breakdown, study by study, on theBPC-157 dosage page.
Common questions
What is a typical BPC-157 vial size?
Research-sold BPC-157 is most commonly listed in 5 mg vials, and 10 mg, 20 mg and 40 mg vials are also sold. This calculator preloads 5 mg as an example vial size only - it is not a recommendation, and it does nothing to verify what is actually in any vial you own.
What dose does the calculator start with, and why?
It starts at 250 mcg, the low end of the 250-500 mcg range most commonly described by clinic and vendor dosing guides - common practice, not trial-established, and not a recommendation. With the preset 5 mg vial and 2 mL of water (2,500 mcg per mL), 250 mcg is 0.1 mL, or 10 units on a U-100 syringe. See the BPC-157 dosage page for what published human and animal studies actually used.
What is the common BPC-157 dose?
The protocol most often described by clinic and vendor dosing guides is 250-500 mcg by subcutaneous injection, once or twice daily, injected near the injury site when possible, for a 4-8 week cycle with a 2-4 week break. That is common practice, not trial-established: no trial or regulator has set a BPC-157 dose.
Is there an FDA-approved BPC-157 dose?
No. BPC-157 has no FDA-approved product and no dose established as safe or effective by any regulator. The common protocol above comes from clinic and vendor guides, not from a regulator. The calculator performs arithmetic on numbers you enter; it does not know what dose is appropriate.
How much bacteriostatic water should I add?
That is a personal choice about how many syringe units a dose works out to, not a fixed rule - more water spreads the same dose across more units, which can make small doses easier to measure. The calculator shows the concentration and draw volume for whatever amount you enter.
Where can I read what BPC-157 studies actually used?
The BPC-157 dosage page lays out the five small published human studies, about 80 people in all (daily rectal enemas for one to two weeks, or one or two injected doses of 2-20 mg, by routes specific to each study), and a rat tendon-healing study dose, with each figure attributed to its source.
