We are continuously testing more products. Scores update with each new result.
Read our scoring methodology →Trust scores are computed from indexed Certificates of Analysis — vendor-published, and lab-confirmed where a lab copy verifies them — using a fixed, versioned methodology (v13). They are not based on independent blind-purchase testing, and no vendor can pay for placement or a higher score. How we score · How we make money
PMB address (-0.03), Non-fixed VoIP phone (-0.04), Full identity on file (0.03), Lab-confirmed (0.02)
