I respect William L for taking the time post these, even though he hasn't tested them himself - But he has to be careful not to suggest some brands/labs are 100% GTG and promote others as "FAIL" seeing as ALL the above samples come from just 3 sources.
All the BD compounds come from just one source for example and he doesn't even know if it's legit or not. I've never used BD myslef, but don't think it's fair to suggest any lab is total sh!te under the guise of lab results based on one set of precarious tests on gear which may or may not be legit in the first place.
The way W.L requested UGL samples on his open board for his up and coming UG Book is wide open to abuse too:

Unless he obtains many samples of the same compound from various batches from UGLabs 100% covertly, I don't see how the results will remain conclusive.
The way he is going about it, the system is very much wide open to abuse from the average Joe, to the top dogs behind the UGL's who may send in dozens of their own perfect "special" batches to ensure the compound 100% passes, or may even tamper with the competitions products to ensure they 100% fail. I'll take a look at the new UG Book when it comes out, I won't be basing the findings on which UGL I choose to use or not use though...
