Most companies don't post or attain a COA for every batch, therefore they could have a legit first batch, but nothing but bunk after.
It's pretty unfair and ridiculous to think that a big name = trustworthy. Gaspari, muscle tech, BSN, etc are all junk but big names.
Every company is new at one time and PNI has been extremely generous with logs and now willing to pay for bloods of some people. If they were terrified of being exposed they probably wouldn't be so willing to expose themselves. A little skepticism is healthy, your levels are absurd.
