I have both of those products. They are both decent pre-workouts. Of the two, God of Rage is my go to when I am looking to do an intense workout. In a comparison to Dust Extreme; Dust Extreme does give me more of a tunnel vision focus, which would be expected since it contains more DMAA. However, God of Rage's focus is still very good and were is shines is in the aggressiveness it causes. The best way I can describe it is that it gives me a F*** Yeah attitude when I'm hitting the weights. It's my favorite pre.
