BPC-157 is a synthetic peptide based on a fragment of a protein found in human gastric juice. Almost all of the research on it has been done in animals, and it has never been approved by the FDA for any use.
Its regulatory status has moved a lot. The FDA had listed BPC-157 among bulk substances that may present significant safety risks in compounding, citing immunogenicity and peptide-related impurities. In April 2026 it was taken off that list after the nomination was withdrawn (FDA). In July 2026, the FDA's Pharmacy Compounding Advisory Committee voted 8 to 6, with one abstention, to recommend adding it to the list of substances pharmacies can compound with, even though FDA staff had recommended against it (AJMC). That vote is only a recommendation. The FDA still has to accept it and finish formal rulemaking before compounding pharmacies can legally use BPC-157.
It's also on the WADA prohibited list, banned at all times for tested athletes.
Much of what's sold online is labelled "for research use only." We don't recommend buying peptides that way. This page doesn't suggest a dose. It only converts an amount you've been given into syringe units, so the number you draw matches the number you intended.
Step 1: Enter your vial size in mg. Use the amount printed on the vial. 1 mg is 1,000 mcg, and the calculator handles that conversion for you. If your vial isn't one of the presets, type it in.
Step 2: Enter the bacteriostatic water you added. More water means a weaker solution and more units for the same amount.
Step 3: Choose your syringe. BPC-157 amounts are measured in micrograms (mcg), so they usually come out as a small number of units. A 0.3 mL (30 unit) syringe is the easiest to read at that size.
Step 4: Enter the amount in mcg. The presets are shortcuts, not recommendations.
With the defaults shown, a 5 mg vial mixed with 2 mL is 2.5 mg/mL (2,500 mcg/mL), so each unit holds 25 mcg and 250 mcg is 10 units. Mix a 10 mg vial with the same 2 mL and 250 mcg drops to 5 units.
BPC-157 is often sold in the same vial as TB-500. Tick Blend next to the vial amount and enter each peptide with its mg, for example BPC-157 5 mg and TB-500 5 mg. Then use Dose Based On to choose whether your amount refers to the BPC-157, the TB-500, or the whole blend. The result shows how much of each peptide is in the volume you draw.
100 units on a U-100 syringe is always 1 mL. How many micrograms that holds depends on your concentration. This table shows common syringe readings at three concentrations.
2 mg/mL is a 2 mg vial in 1 mL, 2.5 mg/mL is a 5 mg vial in 2 mL, and 5 mg/mL is a 10 mg vial in 2 mL. The formula behind the table is: units = amount in mcg ÷ concentration in mcg/mL × 100.
For more on reading the markings, see our peptide syringe units guide. The general peptide calculator covers any other peptide, and PeptideKit can log each dose and remind you when it's time.
Find the concentration by dividing the vial's mcg (mg × 1,000) by the mL of water added. Then divide the amount you need in mcg by that concentration and multiply by 100 for U-100 syringe units. The calculator above does this in one step.
It depends on how the vial was mixed. At 2.5 mg/mL (5 mg in 2 mL), 250 mcg is 10 units. At 5 mg/mL (10 mg in 2 mL), it's 5 units. The number is only a conversion example, not a suggested dose.
10 units is 0.1 mL. At 2.5 mg/mL that's 250 mcg, and at 5 mg/mL it's 500 mcg. Check the concentration of your own vial first.
We can't tell you that, and neither can a calculator. BPC-157 isn't an approved drug, so there's no FDA-reviewed dosing. If you're considering it, speak with a licensed clinician first.
Not yet. An FDA advisory committee recommended adding it to the 503A bulk substances list in July 2026, but that's a non-binding vote. The FDA still has to decide and go through notice-and-comment rulemaking before pharmacies can legally compound it.

Frequently Asked Questions
How do I calculate BPC-157 units?
Find the concentration by dividing the vial's mcg (mg × 1,000) by the mL of water added. Then divide the amount you need in mcg by that concentration and multiply by 100 for U-100 syringe units. The calculator above does this in one step.
How many units is 250 mcg of BPC-157?
It depends on how the vial was mixed. At 2.5 mg/mL (5 mg in 2 mL), 250 mcg is 10 units. At 5 mg/mL (10 mg in 2 mL), it's 5 units. The number is only a conversion example, not a suggested dose.
How many mcg are in 10 units of BPC-157?
10 units is 0.1 mL. At 2.5 mg/mL that's 250 mcg, and at 5 mg/mL it's 500 mcg. Check the concentration of your own vial first.
What is the right BPC-157 dosage?
We can't tell you that, and neither can a calculator. BPC-157 isn't an approved drug, so there's no FDA-reviewed dosing. If you're considering it, speak with a licensed clinician first.
Is BPC-157 legal to compound now?
Not yet. An FDA advisory committee recommended adding it to the 503A bulk substances list in July 2026, but that's a non-binding vote. The FDA still has to decide and go through notice-and-comment rulemaking before pharmacies can legally compound it.
