Basically, you got a series of pre workouts, usually supplements with caffeine and a variety of other things, possibly beta alinine or a variety of things. Research and find out what works for you. I do not use super pump. Its got too much caffeine, I am sensitive so, I found craze works better, and the mental awareness boosters are insane. Novem as well.
Xtend is a bcaa product by scivation but, a intro workout so, you can take with your workout. A pre workout obviously just before but, what works for me and you maybe different Try new things but, research the supplement and be in good health plus talk to your doctor before supplementing. Its not safe to self medicate.
