How to read a COA
A certificate of analysis is the lab's record of what was actually in a sample from the batch. Start with identity: the compound named on the report should match the product you ordered. Then check purity, reported as a percentage of the sample, and the measured quantity against the labeled strength. Finally, confirm the report is hosted on the lab's own site (the links above go straight to the source), not a screenshot.
