It's ok, my first time trying this preworkout so i'm still trying to get a feel for it. As for the flavor it's ok too, i might have to try other flavors to continue to see if this is an effective pre workout for me. I do like the GAT product line especially the EAA, the Pump powders and more.*

People sleep on this pre-workout and I don't know why. I think it's one of the best on the market for energy focus and getting a good pump. Just like most of their products., my biggest knock on it is that the flavor profile It could be much better*

The best for pre-workout. Rest 2 weeks to 1 month after 3 months so as not to accustom the body. The green apple has an excellent flavor.*

GAT has been around for a long time. Even though they don't break down the amount of ingredients, it still is an excellent pre workout with enough energy and focus.*

I prefer the Burn over the OG Nitraflex. Both products get you going for the most demanding workout. Tolerance does build up over time and you do have to cycle it for best results.*
