they caught several sub-99 tests though, which seems to conflict with the “alls well this is just in case” story
I'm not getting into an argument with you, but in my experience, they have one of the highest levels of transparency. What I ordered had a very high purity and I am going to send for endotoxin screening and sterility soon but they have posted sterility reports from other users that have passed. I'm talking proper USP 71 sterility and not Janoshik sterility.
They had a test result for something come out below 99% on one vial (out of three tested) and sent out replacements for free for everyone that ordered it and people could keep the original vials.
While I'm sure you can find individuals who had a bad experience with them, we have to look at things holistically and this company seems to be very transparent with a high % of repeat customers.
