DMAA was banned for a good reason. it is highly addictive and dangerous for your heart and CNS.
all these pre workouts are a joke. once you start using them you are hooked and they do not help your workouts as you think they do. they hurt your workouts. increasing heart rate is counter productive to building conditioning. I recommend you wean yourself off these pre workouts and stick with a well balanced pre workout meal instead, you can use something like Dspark which will help increase pumps without making you jittery like stims will
