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.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.
