This pre is insane!!! It really pushes me over the edge when it comes to tire flips, tire sledges, and well leg day in general. Overall this is great stuff and black cherry tastes just like koolaid to me. Delicious. I highly recommend and even a few of my friends have switched over to the GAT side.

One of the best pre workouts hands down. If your new to pre i do not recommend, but if your experienced and you know what its all about this will still be a bit of a surprise. First time i tried this mid workout i felt the testosterone booster kick in and man! I was on another level, like a alpha mode kicked in.

After reading the reviews on GAT products I decided to give their line a go. I bought the pineapple flavor and it has to be one of the best tasting pre-workout drinks I have ever used. Their seemed to be a little delay in the pre kicking in but when it did my focus and intensity was off the charts. At an hour in on biceps and triceps I could have gone another hour. Pumps were good and had a great work out. Looking forward to seeing what this does over time. Also stacking with Jet Mass. Too early to tell but will write review on it after some use.
