Randomization for bioequivalence & crossover trials

Verify a schedule

Paste a verification spec code to independently reproduce its randomization schedule and confirm it was not altered. This page runs entirely in your browser — nothing is uploaded, nothing is stored. A matching SHA-256 verification code proves the schedule is authentic.

Verify a schedule

Open the randomization tool

Paste your verification spec code

Required — the long code that begins with TG1. Use “Copy spec code” in the tool, or the spec line in your export/PDF.

Verification code from your document (optional)

Optional cross-check only. The short verification code cannot reproduce a schedule on its own — what gets verified is the TG1 spec code above.
