I've read the profile for this but I'm wondering if anyone has any personal experience that this is something good to take for pre workout for increased aggression. Does it take like an hour to kick in or does it take weeks of taking it for to kick in. I'm looking to take it just to get my aggression out and help me with my workouts but not every single day I don't want to run it in my cycle I just want to use it sparingly on days I'm feeling tired
