For PM I have always used Ainterol. They just don't ship the pre-R1 version anymore, so I am on the R1 version now. Regarding brands, this industry has no reluctance whatsoever to get down in the mud and sling lies and misleading half-truths about each other all over the place. I tried the Ainterol for no special reason other than maybe price and availability at the time. It worked well for me, so I have seen no reason to mess with that. I don't believe much of what these vendors and their poorly disguised agents post in forums and comment spaces. I do note that some time ago, Ainterol at least started putting chemical content info on their bottle labels. Not sure anyone validates that the info is right, but I suspect it is. I also suspect it is not necessarily an all-inclusive list, just like I expect the other vendors behave.
