Simply not true.I used generic that is equally as good as pharmaceutical.if I didn't get my pharm.grade for free i would buy the generic pharm.is not worth it.i dare anyone to show me the difference with pics. of themselves and if its not a visable difference your a fool for spending the extra on pharmaceutical grade.
It is true for me and many others, for me, I've used all the Chinese stuff, never again. If I can't get pharm grade then I won't bother. Yes there is a visible difference, if there wasn't I wouldn't spend the extra money. Do I need to prove it to you or anyone else with pics? No.
