there are government run labs in countries like NL that will test drugs anonymously mailed to them for free and post the results. The problem is getting samples to them in an anonymous way that prevents vendors from manipulating the system. Perhaps a fund could be established , and random people selected to make purchases from vendors in a random fashion, and in return for them sending samples in for testing, they get to keep the rest of the (small) order. Then when the lab results are back they can post them here for everybody. It would also be nice if people here reagent test their orders and post the results here, but more sensitive testing is required for the best safety.
