High Quality CBD Source Suggestions

I know that CBD is by no means a cure for ET, but I am looking to it to help with my stress/anxiety, which has been at an all time high for the past year or so with no sign of relief.

There are a gazillion CBD suppliers out there and I know many are selling just oil with barely a trace of CBD.

Those of you that are currently using CBD or have in the past, can you recommend a reputable source that provides a high quality, proven, and document-backed product?

Thanks!
