I have used NO EXPLODE, NANA VAPOR, BLACK POWDER, NO SHOTGUN you name me ive tried it. I just recently bought this cytonox and im one week into it and it is pretty good pre workout supplement. Within one week I feel alot stronger and alot l feel more energy than i did with the other pre workout supplements. I love the feeling being pumped with this supplement. Also im using it with cytocell, tren extreme and mass extreme.
