I had 3 of the same exact vials about 4 months ago, everyone said it was fake so I wasn't going to use it, but I went ahead with it... Was using 200mg EOD. I was using it with 600mg Deca, and it PARTIALLY prevented Deca dick, sometimes I was fine, and 3 or 4 times, I was just about to stick it to my girl, and my damn dick went floppy again.... Damn ridiculous. Had to be very underdosed.....
