Oxydrene is a great product. It works well for me providing extra endurance for more productive workouts without altering my focus or concentration. I find it especially useful for cardio in particular, preventing fatigue and helping me to push harder and do more. I have used other products with similar claims but none have worked as well as Oxydrene. Oxydrene is my favorite pre-workout product—it works and no nasty side effects for me.
