Quick Answer
To reconstitute a BPC-157 + TB-500 blend vial, divide the total mg in the vial by the mL of bacteriostatic water to get mg per mL, then split it by the blend ratio to get each peptide’s share. For a draw, divide the amount in mg by the concentration to get mL, then multiply by 100 for units, since 1 mL is 100 units on a U-100 syringe. Example: a 10 mg blend vial (5 mg BPC-157 and 5 mg TB-500, a 1:1 ratio) in 2 mL of water is 10 / 2 = 5 mg per mL in total, or 2.5 mg per mL of each peptide. A draw of 500 mcg of the blend is 0.5 / 5 = 0.1 mL, which is 10 units and contains 250 mcg of each peptide.
BPC-157 + TB-500 10 mg Blend: Concentration at Different Water Volumes
The table shows the math for a 10 mg blend vial at a 1:1 ratio (5 mg BPC-157 and 5 mg TB-500). The draw column uses 500 mcg of the blend only as a worked example. Change the numbers in the calculator above to match your own vial, ratio and amount.
| Bac water added | Total concentration | Each peptide | Draw for 500 mcg of blend |
|---|---|---|---|
| 1 mL | 10 mg/mL | 5 mg/mL | 0.05 mL (5 units) |
| 2 mL | 5 mg/mL | 2.5 mg/mL | 0.1 mL (10 units) |
| 3 mL | 3.33 mg/mL | 1.67 mg/mL | 0.15 mL (15 units) |
More water gives a lower concentration and a larger draw for the same amount.
10 mg and 20 mg Blend Vials at 2 mL
The concentration depends on the vial size. The table keeps the water at 2 mL, the ratio at 1:1 and the draw amount at 500 mcg of the blend.
| Vial | Total concentration | Each peptide | Draw for 500 mcg of blend |
|---|---|---|---|
| 10 mg (5 mg + 5 mg) | 5 mg/mL | 2.5 mg/mL | 0.1 mL (10 units) |
| 20 mg (10 mg + 10 mg) | 10 mg/mL | 5 mg/mL | 0.05 mL (5 units) |
A larger vial in the same water is more concentrated, so the same amount is a smaller draw.
How to Reconstitute a BPC-157 + TB-500 Blend: The Math Step by Step
These steps cover the arithmetic of reconstituting a BPC-157 + TB-500 blend vial, including a 5 mg BPC-157 plus 5 mg TB-500 vial. They are not handling or dosing instructions.
- Read the total mg on the vial and the ratio of BPC-157 to TB-500. A 1:1 ratio on a 10 mg vial is 5 mg of each.
- Pick the volume of bacteriostatic water in mL.
- Divide the total mg by the water volume to get the concentration in mg per mL, then split it by the ratio to get each peptide’s mg per mL.
- Divide the amount you want to draw, in mg, by the total concentration to get the draw in mL.
- Multiply the draw in mL by 100 to get units on a U-100 syringe.
Example: 10 mg in 2 mL is 5 mg per mL, so 0.5 mg of the blend is 0.1 mL, or 10 units. The calculator also has a Separate Vials mode for BPC-157 and TB-500 in two vials.
Frequently Asked Questions
Can I download a PDF of my BPC-157 + TB-500 blend calculation?
Yes. After you click Calculate, a Download Free PDF button appears next to Copy result. It opens a one-page report with your inputs (vial weight, ratio, bac water, amount and syringe type) and the results, which you can save as a PDF. The report is arithmetic only and does not recommend an amount.
How do I reconstitute a 10 mg BPC-157 + TB-500 blend vial?
Enter the total vial weight of 10 mg, choose the blend ratio and enter the bac water you plan to add. For a 1:1 ratio, 10 mg in 2 mL is 5 mg per mL in total and 2.5 mg per mL of each peptide, and the draw in mL is your amount in mg divided by 5. Multiply by 100 for units on a U-100 syringe. This is arithmetic only, so use the figures printed on your own vial.
