Shop withheld — during active brand-owner enforcement we do not attribute test results to individual shops. Lab, date, lot and results are shown in full. Measured amount in amber when it is under 90% or over 130% of the label. Records without a lot number link as View →. Community marks a certificate a member sent in, not the shop.
Listed so every record stays one click away. These pages stay out of search until they reach 5 tests.
