Bests & Worsts Reviews from Amazon

I have been buying this brand for years. The claims on the carton and their web-site are impressive but may be nothing but marketing ploys. When i called them for a copy of their certificate of analysis (an independent lab analysis of their actual product) they refused to provide a copy. So, what's ACTUALLY in the bottle? It's a mystery. I decided, to no longer dish out my hard-earned $$$ for a mystery pill. Please, share your certificate of analysis for the customers to see. Thank you.
