This tool makes no safe/unsafe, genuine/fake, or supplier-quality judgment.

What the checklist is based on
Analytical methods must be assessed for their intended measurement. Identity, purity and assay are distinct analytical purposes. The checklist applies basic completeness and arithmetic checks; it is not a validated analytical procedure.
