Centurion Labz has been one of the most hardcore supplement brands since it's inception in 2014. While they're early focus was on hardcore supplements like pro hormones and hard hitting pre workouts, they began to shift towards performance supplements across all categories. Centurion Labz has 3 pre workouts. God of Rage, God of War, and God of Rage Reloaded. Each one serves a different purpose, and each delivers exactly how you want it to. Stack any pre workout with the popular pump, blood rush for an insane workout experience.
