A COA from your peptide vendor means the vial is actually clean

Peptide X is going back and forth over two seizures in Canada. Posts say one batch from a research-chem vendor tested positive for bacteria, and a second seizure hit a wellness clinic selling RUO peptides. Half the replies are "this is why I only buy from vendors with a COA." But a COA is usually one test on one batch, often paid for by the vendor, and purity testing doesn't check for endotoxins or bacteria at all. Does a COA actually mean your vial is clean, or is it just marketing?

purity % and sterility are two totally different tests. most COAs people post are HPLC only
so what are we supposed to do, send every vial to a lab ourselves?
which vendor got seized? without a name this is just fear posting
cap that most vendors even test. half those COAs are the same pdf with the date changed
