Meh, but who knows what else they put into their products. Would you really trust taking any supplements designed by those 2 brain surgeons (PJ and Aaron)? 
Um....we're taking a mildly effective PH here bro. This shit isn't heroin.
Do you always live a life of fear and uncertainty? I'm a proponent of doing things cautiously and minimizing risks, but living a life of fear in the way you advocate sounds awful. By your standards we should never take anything, ever, no matter what, because we can never be sure that what we took is actually what the label says.
Also, PJ and Aaron didn't come up with this. This compound has been in existence for years and years but never mass marketed because they found other arguably better PH's to market and sell and eventually ban. This is how the PH market works. Tweak a molecule here and there and create a brand new drug that isn't a scheduled drug; then market and sell it until new federal regulations ban it.
