There are many dietary & nutritional supplements that are "USP" or "pharmaceutical grade"...it's a standard of purity - NOT a relationship with "Big Pharma". Using a substance that is USP/pure doesn't mean anyone is "100% pro pharma".
Yes, it is a level of purity. A level of purity that allows it to be used as an injectable pharmaceutical.
But once again the simple concept went right over the "liver flush" supporters heads. If you go back and carefully read the post that started this I was showing how easy it is to stretch things to make any point you want. One of the "liver flush" supporters tried to claim that the link I posted was pro-pharma. My point was that the link was no more pro-pharma than the magnesium sulfate used by "liver flush" supporters that is manufactured by pharmaceutical chemical manufacturers. But their desire to attack overwhelmed their common sense and so they had to continue with the personal attacks and debate ignoring what the original post was really about.
