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.*

This pre-workout supplement is a game-changer! From the moment I took it, I could feel the surge of energy and focus. It kickstarts my workouts and keeps me pushing through the toughest routines. The taste is great, and there's no jittery crash afterward. If you're looking for a reliable way to take your workouts to the next level, this pre-workout is a must-have. Highly recommended!*

I initially thought the new formula was not good as the previous predecessor. But it provide me wrong when i started using this product. Better sustained pumps through out the day with extreme tunnel vision focus in the gym while workout sessions. Boron is clinically dosed at 200 mg which i raises the testosterone levels is an added benefit*
