I used to use Superpump, Jack3d, and other pre-workout energy products. Those are good too, but they are nothing compared to Nitro-NCG. I have never used anything like it. Drink it about 30-45 minutes before you hit the gym and I promise you, you can literally lift for hours. You'll finally have to stop your workout because you have other things you need to do in your day. There's no crash like some products and it doesn't give you the jitters. Really good product. Would not recommend more than two scoops though. The first time I used it, I worked out longer and harder than I ever had been able to before and I literally puked in the locker room. If you need energy and want to hit the gym hard and heavy, this stuff is power packed!

Nitro NCG is by far the most bang for your buck. This stuff delivers exactly what it promises. I've tried Jack3D, Superpump, etc and those provide some energy but they pale in comparison to Nitro NCG. If you mix two scoops in a bottle of water and drink it about 45 minutes to an hour before you start your workout, you will literally have to make yourself leave the gym because you have other things do get done. You can literally workout for hours on end with this stuff and it doesn't give you the jitters or the crash that other products give you. I love this stuff
