Free peptide tools for reconstitution math, dose planning, and fewer spreadsheet mistakes.
Featured Tool
Convert vial amount, dilution volume, and target dose into precise mL per injection. Supports U-100 insulin syringe units and mg-to-mL conversion.
Built Into the App
When you enable inventory tracking in the app, the built-in calculator handles reconstitution math automatically every time you log a dose.
Peptide math is simple in theory but easy to mess up in practice. A decimal place error in concentration can mean dosing 2x or 0.5x your target. These tools remove the guesswork.
No rounding errors or manual formula mistakes
See concentration and dose volume immediately
Works on phone, tablet, or desktop browser
