You've found a supplier with a shiny PDF on their site, but does that COA actually cover the exact product in your hand? In the EU, regulations around CBD products are still a patchwork, and some suppliers will happily point to a single COA for their entire line. That's not how it works.

Ask: "Can you send me the COA for this specific batch?" If they stall or say "it's the same for all," that's a warning sign. Real testing happens per batch because materials and manufacturing conditions can change. A COA is only meaningful when it matches the batch number printed on your device's packaging.
