In my opinion, there is no reason for a vendor to test their batches. If you have half a brain cell, you wouldn’t trust results they post anyways. It’s so easy to skew those. I’m sure BBA has good stuff, but testing yourself is the only way to know
Testing on new production runs is insurance on production fuck ups. Internal testing is a mandatory protocol IMO. It is already deployed by others in the space now. The top suppliers all do this because they won’t to know the 1000 boxes of Tirz is made to spec
Very true if you’re talking about a vendor testing their own raws or testing for their sake. I’m just saying that as a customer, it shouldn’t mean anything to you
