The supplements market is full of shysters and charlatans. If they had the actual data to prove it, they would have published it.
Another piece of data we have is all the anecdotal stuff about it simply working for people, personally I think it is pretty hard to placebo not getting diarrhea.
I do agree with you about the supplement industry being full of scumbags. Let me know what you would like from us to help win you over, besides the double blind which is in progress, but imagine if it was not an option, what else?
