I have built a tolerance when it comes to preworkouts. So i took some time off Noxipro worked well, No jitters no trouble sleeping, good burst of energy before i train. Ive taken it on empty stomachs, amd weith some food, good either way started with a scoop, and about 6 oz of water. the less water the more effective i feel. I sometimes mix with applejuice or some type of juice if its the afternoon after work and i need that kick

Noxipro is such a sick product I couldn't imagine my workouts without it.  
 
The bottle is so unassuming.. What's hiding within the bottle will give you some of the best workouts ever had.
