Editorial principle
Trust, but verify.
Supplier claims are a starting point, not a conclusion. We look for independently verifiable laboratory evidence, batch traceability, transparent business practices, and a consistent track record before those claims influence a ranking.
Evidence hierarchy: Primary records and independently verifiable laboratory reports carry more weight than vendor claims. Customer reports can reveal patterns, but allegations are not treated as proven laboratory findings.
