Ask what was tested
Testing may address ingredient identity, stated amounts, contaminants, or banned substances. Those are different questions; a quality logo is not a clinical benefit claim.
Verify the claim
Check the certifier’s own directory for the exact product and current certification. For a certificate of analysis, check batch number, date, methods, laboratory, and which substances were measured.
Look for transparency
A useful manufacturer can explain its sourcing and testing and provide matching documentation. “Lab tested” without a laboratory, batch, or test scope gives little detail.
What testing cannot tell you
A passing result does not prove effectiveness, suitability for your medicines, or absence of every possible contaminant. No individual product is tested or endorsed by this site.
