That was kind of my point. From everything I can tell you may be getting fire and then it's not anymore. I don't think any supplier can be vouched for as far as I know. And tbh, not trying to sound like a dick here, If I came across a legit supplier that was always on point I don't know if I would spill the beans. I wouldn't want to fuck up my situation at that point.
My take on it is to call out a supplier when they don't fix an issue rather than just supplying a bad batch. I would hate to have accosted a clerk at a CVS because a recently purchased bottle of lets say multivitamins are bad. If CVS laughs at me and tells me 'at least it's cheap' or something like that you will have a different tune being played for sure but if the supplier comes correct then all is well in the bathtub brew world I'd say.
It's truly more of a 'what the hell am I really putting into my body' sanity check. also, from what I have been told and read you are looking at several hundred dollars per test.
