Check it yourself
You do not have to trust this page, or the vendor. Bioviridian Inc. publishes its own lookup, so the report can be pulled from the laboratory directly.
Every certificate prints a Web Verification Code at the top right — COA followed by four digits. Enter it on the laboratory’s COA search page, or open https://bioviridians.com/coas/<CODE>.pdf directly; a code the laboratory did not issue returns 404. The certificates print the lookup domain as “biovidians.com”, a misprint that does not resolve — the laboratory is bioviridians.com.
Open the Bioviridian Inc. lookup and compare what it returns against the figures above. If the two disagree, the laboratory is right and we want to hear about it.
A certificate describes the sample it names and nothing else. It is not a statement about any other lot, and it is not an endorsement of the vendor or of any use of the material.
