Why Batch Matching Matters
Use the Lab Results page to locate available third-party reports. Match the product and batch or lot identifier before relying on a report, then review the analytes, methods, dates, and reported results within that document.
What to Review in a Report
Review which analytes were included, the reported methods and dates, product and batch or lot identifiers, and the values shown in the report. A report should not be treated as covering products or batches it does not identify.
How to Read a COA
If you have never read a kratom Certificate of Analysis before, our Kratom Journal article 'How to Read a Kratom COA' walks through every field — what to verify, what to ignore, and the common ways a sketchy vendor can produce a real-looking but meaningless document. It's worth ten minutes before you buy from any kratom brand, including us.
