Keep in mind that essentially everyone is allowed to participate as a vendor.
The lab test report requirement represents the absolute minimum to post in the Underground. Nothing more. Nothing less.
It does NOT represent an attempt, in any way whatsoever, to satisfy a requirement for approval, endorsement, validation, vetting, accountability, or trustworthiness of brand's product/services.
A few random lab test reports here and there are not enough. Community members should demand more. (Quantitative/qualitative/microbial testing of every batch of every product offered is a start...)
I hope this goes without saying. But in case it doesn't, it's now been explicitly stated above.
