5. What This Verification Does and Does Not Mean

5.1 Buyer explainer block

What this check tells you

1. The NFC Tag responded like a registered Res Labs Tag. The system checked the Tag’s cryptographic response and replay signal.
2. The Tag points to this Supplier batch record. Res Labs found the Tag in its registry and displayed the batch it is assigned to.
3. There is a recorded third-party Lab COA for the batch. The page links to the official COA on the Lab’s own domain and may show a recorded document hash, IPFS reference, or blockchain anchor to help detect later document changes.

What this check cannot tell you

1. Res Labs did not test this vial. We did not open it, sample it, or analyze what is inside.
2. “Verified” is not a purity or safety result. It does not prove identity, potency, concentration, sterility, freedom from contamination, legality, or suitability for any use.
3. A real COA is not the same as a tested vial. The Lab generally tested one or more samples presented as part of a batch—not every vial. The Supplier is responsible for connecting the right sample, batch, Tag, and vial.
4. A genuine Tag can still be misused. It can be put on the wrong vial, moved, stolen, damaged, or paired with inaccurate information.

How to use the page

Open the official COA on the Lab’s domain, check which tests were actually run, compare the batch details with the vial, and make sure the page has no warning or recall. Stop and contact the Supplier and Lab if anything does not match.
