About Our Rankings
Our vendor rankings are based on comprehensive independent evaluation across five key criteria. We purchase products from each vendor, verify purity claims through testing, evaluate the ordering and delivery experience, and assess customer support responsiveness. Rankings are updated quarterly to reflect changes in vendor performance.
