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.
