WE USE AI TO LINK VENDOR INFORMATION

What a verified test proves (and what it does not)

A verified lab result proves that one specific vial, shipped by one contributor, contained what the report says at the time of testing. It does not prove the vendor's whole batch, future batches, or ongoing supply match that result. Treat every score as evidence, not a guarantee.
