you are absolutely right thanato, i knew this the difference is we are buying the actual single most effective ingred. dr katz is a rip off because his is mostly water and very tiny amount of this oxygen, so better off buying the stuff and see dr.katz works for me but i have to use it several times a day like every hour. which is rediculous because i would go through a bottle a week at 10 dollars a pop. neway i know it wont work for everyone but it does work for me, dont get me wrong its not a cure but i've tried everything this forum has to offer from cleansing to grape seed to sun-chlorella it all was BS and i'm sorry that this stabalized oxygen is BS for others but theres gotta be someone else this works for......
