where can i find Hydroxy Citric Acid???

I am looking for hydroxy citric acid (HCA). according to a post on this board, it can be found in "Citrimax". however, i called the nutrition store, and not only do they not carry it, but they said it is not an ingredient in Citrimax. any help or info will be greatly appreciated.

SORRY, already found the answer. i called the other supplement store and (they have it in many different forms. I guess different supplement stores carry different products, (and these two stores are literally 500 ft. from each other....
later.

I was gonna be a smart ass and say you could make it from citric acid....but oh well enough being a smart ass for the day!
