Run the Numbers
Calculate concentration per compound for a blended vial — the calculator keeps BPC-157 and TB-500 separate so each stays accurate. Free, no login required.
Open the free calculator →BPC-157 + TB-500 Blend Dosage Calculator
Enter each compound's mass, the shared bacteriostatic water volume, and a draw volume — BPC-157 and TB-500 are calculated separately. For research purposes only; reconstitution math, not a dose recommendation.
Calculating a two-peptide blend
Researchers sometimes reconstitute BPC-157 and TB-500 together in a single vial. The math is the same per-compound formula applied twice, because each peptide has its own mass in the blend but shares the same water volume.
Worked example (illustrative math only)
Say a blend vial contains 5 mg BPC-157 and 5 mg TB-500, reconstituted in 3 mL of bacteriostatic water:
- BPC-157 concentration = 5 mg ÷ 3 mL ≈ 1.67 mg/mL
- TB-500 concentration = 5 mg ÷ 3 mL ≈ 1.67 mg/mL
Because both share the same water volume, a single measured volume draws a proportional amount of each compound. The calculator handles each component separately so the concentrations stay accurate.
Why this trips people up
The most common error is treating the blend as one 10 mg quantity. It isn't — each compound is calculated on its own mass. The calculator keeps them separate.

Frequently asked questions
How do I calculate a BPC-157 and TB-500 blend?
Apply the same reconstitution formula to each compound separately. Each peptide has its own mass but they share one water volume, so each concentration equals its mass ÷ the shared water volume. The calculator above keeps them separate. For research purposes only.
Do BPC-157 and TB-500 share the same water volume?
Yes. When reconstituted together in one vial they dissolve in the same bacteriostatic water, so a single draw pulls a proportional amount of each compound based on its individual concentration.
How much of each compound is in one draw?
Multiply each compound's concentration by the draw volume. For example, 5 mg BPC-157 and 5 mg TB-500 in 3 mL water both give ≈1.67 mg/mL; a 0.5 mL draw contains ≈0.83 mg of each.
Is this medical or dosing advice?
No. BPC-157 and TB-500 are research compounds and are not FDA-approved. This page and calculator describe laboratory reconstitution math only and do not recommend any human dose.
