I have the 10cc one, and I've heard that if you have the real one, prepare to blow UP! But, it's very hard to come across it. People have told me that this brand is infact one of the most counterfeit tests out there. I will be taking my 4th shot tomorrow morning, to make two this week. Nothing so far (except for increased appetite, but that could me mental), but it hasn't even been 3 weeks yet.
