## FAQ

### How do I calculate peptide concentration after adding bacteriostatic water to a vial?

Divide the total mass of dry compound by the volume of liquid added; the result is concentration per mL. A calculator can automate this and also output draw volume, U-100 units, and estimated number of draws per vial.

### What does U-100 mean on a lab syringe and how does it affect reconstitution math?

U-100 syringes have 100 graduation marks per mL, so 1 unit equals 0.01 mL. Converting a target volume into U-100 units lets a researcher read the syringe scale directly rather than calculating fractional milliliters manually.

### How do you calculate the math for a peptide blend in one vial or cartridge?

Add the individual reconstituted volumes of each compound into a single container, then track each component's concentration separately. A blend planner tool handles the combined volume and per-component concentration accounting automatically.
