Great flavor. Took a full scoop the first time and holy moly.  Definitely recommend a half scoop to assess tolerance.  This will get you going on the days you feel sluggish*

Love this pre workout, it's strong stuff and gets you sorted for you're workout. Flavour could be stronger, but mix with less water and it's not too bad*

Green apple came in and it's fantastic I'm not sure how this is hyperemia & testosterone enhancing but it's regular Gat Nitraflex and the watermelon flavor has no flavor and smells like chemicals.*
