Saw another post awhile ago saying that Corion was fake. But I couldn't believe that someone would make one of the most professional fakes ever over a $20 5,000iu HCG kit. So I used the whole 5,000 kit on a preg test and the results were most definitely positive...although it isn't quite so clear in the pics. My wife took one look at it and agreed it was positive. One thing u have to remember too is that 2ml on a preg test is next to nothing. The directions call for 5 seconds in a piss stream.
