I really enjoyed N.O. Xplode it boosted my energy quite well but the more i used it i felt the more that i became immune to it. It gave me a really good pump and i felt my muscles bulge when i used it. it seemed to stack well with other products. This was my favorite pre workout supplement. I have tried every flavor and they all tasted good blue raspberry being my favorite by far. This kept me alert from the instant i took it i often spent my rides to the gym finding my self driving faster then normal wanting to get there and tackle the weights. overall this product was very good and i recommend it.
