Has anyone tried this? It's a pre workout supplement thats supposed to give you energy for your workout.
I tried half a dose yesterday and it did make me feel energized. Too energized actually so that I didn't sleep until 2am.
I am asking because I usually go to the gym after work. Some days it feels like i hardly have energy to go. It was helpful yesterday and I was thinking of continuing it. But I'd like to ask for feedback from people who have actually used it regularly. Are there any long term side effects? Also, could you build a tolerance against it?
