I for one, would just like to know which is the most potent, consistent brand of manufacturer out there.... I am not inclined to follow every high brow scientific study put out by Paul, John, Ringo etc. Just site an opinion and point to supporting docs if there is any.

Just like other unregulated things out there... Too many 3rd party brands that could cut product with God knows what!

My frickin head is swimming! ! !
