Bronchogen COAs
A COA shows the batch it names, not the lot shipped today. Vendors post certificates for specific batches; none of them shows which lot a vendor ships now, and a missing COA is shown as missing.

By product and vendor
Each row is one vendor's offer for one exact product. It shows the report behind the testing state: for a lab-verified product the newest report the lab confirmed, otherwise the newest report on file. A lab link appears only where the lab confirmed the report. Every archived report is stored with its SHA-256 hash.
