Here is a list of lab reports, organized by vendor and batch. The link to the original page is provided, along with related links. I have saved as much as possible in case the original links 404. As I get more reports, I will fill out this page further.
If you have any reports, please send them to /u/KamajiTheBoiler on reddit. If you are considering getting your stuff lab tested, please do and share the results. You are helping everybody.

The bottom line is that can mostly trust these lab reports, but the only way to be certain is to send in a test for every batch you buy and know for yourself what you bought. We have no idea if Energy Control is lying to us, we're forced to trust them for the time being.
