Claim interrogation

Four passes through a peptide claim

  1. 1

    Name the peptide

    Do not stop at the category word.

  2. 2

    Find the formula

    Ask whether the finished product was tested.

  3. 3

    Read the endpoint

    Check what the study actually measured.

  4. 4

    Match the promise

    Keep confidence proportional to the evidence.
