i can't remember what I bought. but its one of those things you drink the day of the test. so you do want one that works. keep drinking the tea and see if you can find a "day of the test flush" that works.
the guy at my GNC was the one that recommended the one i bought. he said people come in all the time for it.
I do remember one thing about it. it was 30$ and it had a double your money back thing on it. but it worked. kinda expensive.
was yours that much or less?
