This is my favorite pre workout. I get intense energy to get me through my workout. Flavor is not bad and serving is a small scoop.*

At first I wasn't sure if it was for me but after using a few times it definitely kept me going during hard workouts. Wish it had a little more beta alanine.*

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.*
