This **** should be pulled off the shelves. I took this crap, And it is crap... And I seriously thought I felt like I was doing to die! I didn't even take a full scoop and yet I got to the gym and was freaking the hell out. My heart was racing a million miles an hour, I was shaking and according to a trainer I was turning white, I got really cold. I don't know what they put in this crap but I'm surprised its still on the shelves. I thought it was just me so I let two of my friends try it and sure enough they had a similar experience. It does help you focus though... Focus on not trying to die. I had to sit down for 30 minutes before I felt somewhat normal again. Has anyone else tried this crap?
