They have a Gofundme page set up for it. I don’t know the specifics of who owns or operates it, though. It’s supposed to be independently run. They don’t take donations of gear, they order it directly from the source just like a regular customer so that the source doesn’t know they’re being tested. Several of the products have been shown to be underdosed as well as to be completely bunk. There doesn’t appear to be any rhyme or reason nor agenda at play by a certain entity, but it’s always hard to say for sure.
As far as I can tell, the lab is in Europe, and I assume the people running the site are as well. The of the gear tested is predominantly available from international suppliers that are based in Europe.
