What the Evidence Score means

It adds up points for what we could verify about VAYN: lab reports we matched to the issuing lab's own public record (the biggest part), how often it tests, what the reports cover, contact details, policies, card payments and how long the site has existed. Each card below shows exactly which checks it passed. A higher score means more you can verify yourself; it is not a safety rating, and ads or affiliate deals never change it.
