I grabbed a bottle of this stuff at edge nutrition. I have taken the recommended dose for a few days now. It seems like it has some great effects in the gym in terms of endurance and focus but the side effects seem extreme in my case. Jitters for hours afterwards regardless of water and food intake, anxiety, I believe it may be causing recent headaches, excessive urination from diuretic ingredients etc...Usually, I have NO sensitivity to most pre-workouts (have tried most)..frankly they don't ever seem to effect me in any way so rarely use them. Think I am going to discontinue use, no real ROI here.
