I tried total war pre workout from Redcon1 the other day and loved the feel! Long lasting energy and great overall feel. I was worried because it has Ampiberry, which I have not liked in other supps, but this one is just right. It will not blow your doors off if you are a hardcore stim lover, but great overall. I tried Tiger's Blood flavor and while I made it to the directions, I had to add more water for it to taste decent. REALLY strong flavor, I suggest more water. Anyone else try this yet? If so, how did you like it?
