Top 3 vendor evidence profiles for Liraglutide
Eligible vendors have at least 2 deduplicated tests and 2 classifiable identity observations. Rank uses the 95% lower confidence bound on clean identity results; mean positive purity and test count break ties. Missing measurements are not passes. Exact-zero/not-detected and explicit wrong-compound markers count once per adverse certificate. This describes tested batches, not every product or shipment, and is not an endorsement.
