A COA should say: what was tested, method, date, lab name, and how it ties to the batch. If it’s just a pretty PDF with no chain of custody, it’s marketing.

I’ve seen lab tested with zero actual numbers. Like… tested for what? That phrase is meaningless without details.

Also watch for mismatch: COA date from years ago, but the product claims “fresh.” Or no units, no detection limits, no signatures.
