Anyone here use pre-workout supplements so they are energized fully for an optimal workout? Since I started working, I've been getting less sleep and it's affecting my workouts. My workout frequency isn't exactly that high so I need to make all my workout sessions count. Caffeine has little to no affect on me now, considering that I'm drinking coffee everyday at work on top of the fact that I'm naturally pretty tolerant to it to begin with.
I've heard of stuff like N.O. Fury (I think Raptor uses it), and C4 or whatever...
Any recommendations on a specific supplement?
- Also it'd be nice if you add in information such as if it includes caffeine, if you experience a crash later, how long it lasts in your body, does tolerant build up, etc...
I am pretty clueless and completely inexperienced with pre-workout supplements.
