BPC-157 Dosing Calculator & Reconstitution Guide
A synthetic peptide researched for tissue repair and gut health.
To calculate a BPC-157 dose, divide the vial micrograms by the bacteriostatic water added to find concentration, then divide your target dose by it. Example: a 5 mg (5000 mcg) vial in 2 mL water is 2500 mcg/mL, so a 250 mcg dose is 0.1 mL — 10 units on a U-100 insulin syringe.

What is BPC-157?
BPC-157 is a pentadecapeptide derived from a protein found in gastric juice. It is studied for its potential effects on tendon, ligament, and gut tissue repair. Research doses are commonly expressed in micrograms per day. Also known as Body Protection Compound, BPC.
How many units is each BPC-157 dose?
| Dose | Volume to draw | Units (U-100) |
|---|---|---|
| 250 mcg | 0.1 mL | 10 units |
| 500 mcg | 0.2 mL | 20 units |
Based on a 5 mg vial reconstituted with 2 mL of bacteriostatic water (2.5 mg/mL) and a U-100 insulin syringe. The dose amounts shown are commonly reported by the community and in anecdotal research, not recommendations or medical advice; only the reconstitution math (volume and units) is calculated for you.
How to calculate a BPC-157 dose
- 1
Choose your vial and water
Select your BPC-157 vial size (for example 5 mg) and the volume of bacteriostatic water you will add (for example 2 mL).
- 2
Find the concentration
Divide vial milligrams by water volume. 5 mg in 2 mL gives 2.5 mg/mL.
- 3
Calculate the draw
Divide your target dose by the concentration to get the volume in mL, then multiply by 100 to get units on a U-100 insulin syringe.
- 4
Verify on the syringe
Use the Keel calculator to see the exact draw rendered on a to-scale syringe, with a warning if the dose exceeds the syringe capacity.
BPC-157 dosing FAQ
How many units is 250 mcg of BPC-157?
With a 5 mg vial reconstituted in 2 mL of bacteriostatic water (2500 mcg/mL), 250 mcg equals 0.1 mL, which is 10 units on a U-100 insulin syringe.
How much bacteriostatic water for a 5 mg BPC-157 vial?
2 mL is a common choice, giving 2500 mcg/mL so that a 250 mcg dose is a clean 10 units. Using more water makes the draw larger and easier to read.
What BPC-157 doses do people report?
Anecdotal community reports and research write-ups commonly cite 250-500 mcg per day, sometimes split into two injections, often paired with TB-500 in recovery stacks. These are figures people report rather than a recommendation from Keel.
Which syringe is best for BPC-157?
Because BPC-157 doses are small, a 0.3 mL (30-unit) U-100 insulin syringe gives the most precise measurement. At 2500 mcg/mL a 250 mcg dose is only 10 units, which is easy to read on the smallest syringe.
How should I store BPC-157 after reconstitution?
Reconstituted BPC-157 is generally kept refrigerated and protected from light, while the unmixed lyophilized powder is stored cooler still. Follow the storage guidance from your supplier or a licensed healthcare professional.
