ABOUT THIS LIST
Verification status on this list is determined through independent blind testing. I personally purchase products from suppliers and submit samples to Janoshik for analysis without their knowledge. Suppliers are not permitted to submit their own testing results for verification purposes, as this methodology eliminates sample selection bias and ensures tamperproof assessment.
