How to reconstitute BPC-157
BPC-157 usually comes as a freeze-dried powder in a 5 mg or 10 mg vial. Before it can be measured it has to be mixed with bacteriostatic water, and the amount of water you add decides what every mark on the syringe holds.
- 5 mg vial: add 2 mL of bacteriostatic water. That makes 2.5 mg/mL, so each unit on a U-100 insulin syringe holds 25 mcg, and 500 mcg is 20 units.
- 10 mg vial: add 3 mL of bacteriostatic water. That makes 3.33 mg/mL, so each unit on a U-100 insulin syringe holds 33.3 mcg, and 500 mcg is 15 units.

Step by step
The same steps as the video, in writing.
- Check the label.
The vial says how much powder is in it: 5 mg or 10 mg.
- Draw the water.
Use bacteriostatic water: 2 mL for the 5 mg vial; 3 mL for the 10 mg vial. If it's more than 1 mL, a 3 mL syringe does it in one draw.
- Add it slowly.
Let the water run down the inside wall of the vial, then swirl gently until the powder has dissolved. Don't shake it.
- Write the strength on the vial.
For the 5 mg vial that's 2.5 mg/mL, or 25 mcg per unit, plus the date you mixed it.
- Find your amount.
Read the units from the chart, or put your own numbers in the calculator. Then check it backwards: units × mcg per unit should give the amount you wanted.

Questions
How much bacteriostatic water do you add to a 5 mg BPC-157 vial?
In the Reconstitution Insights video, Matthew adds 2 mL. That makes 2.5 mg/mL, so each unit on a U-100 insulin syringe holds 25 mcg. You can use more or less water: the amount of peptide in the vial stays the same, only what each unit holds changes. The calculator works it out for any amount.
How much bacteriostatic water do you add to a 10 mg BPC-157 vial?
In the Reconstitution Insights video, Matthew adds 3 mL. That makes 3.33 mg/mL, so each unit on a U-100 insulin syringe holds 33.3 mcg. You can use more or less water: the amount of peptide in the vial stays the same, only what each unit holds changes. The calculator works it out for any amount.
How many units do I draw for an amount of BPC-157?
Divide the amount you want (in mcg) by what one unit holds. For example, 500 mcg from the 5 mg vial mixed with 2 mL is 20 units (0.2 mL); 500 mcg from the 10 mg vial mixed with 3 mL is 15 units (0.15 mL). The chart above lists the other amounts.
What is a unit on an insulin syringe?
U-100 insulin syringes are marked in units: 100 units is 1 mL, so 1 unit is 0.01 mL whatever the size of the syringe. A 0.3 mL syringe holds 30 units and a 0.5 mL syringe holds 50.
