I have tried so many PWo drinks over the years...NO Xplode, Jack3d, Dark Matter, Animal Rage, Razor 8, Ezekiel, Mesomorph, ASGT, 1MRP, you name it I have tried at least a sample of it...nothing has come close to what N2KTS does for me...and yes I add N2 Amp too for the most kick ass workouts, and no crash!!! Nice smooth energy through the morning!
