Recommended supplier

I have a few question about COAs. How do you know if the COA is real and not just a copy of some other companies? Also how do I join a testing group? How do know if the COA is from the same batch you purchased?? Any advise would be greatly appreciated.

There is no way to know unless you test it yourself, which is highly recommended. The best you can do is go with a vendor where several sources have reported their own COAs that meet the COA requirements.and have had good results.
