Three things every COA confirms.
Identity verified
HPLC + mass-spec confirm what’s in the vial actually matches the label.
Lot-level traceability
Every COA is paired to its production lot, so you can match documentation to the vial in your hand.
Domestic third-party labs
Independent U.S. labs handle every analysis — no in-house fudging, no overseas certificates.
