i'm 17 years old and i've started to workout out a lot more than i used to. When i'm done working out i take the gnc brand protein 100% whey. i want to start taking something before i workout. i've heard of NO shotgun, black powder, and super pump 250. I was going to go with black powder but came arcoss super pump 250 and don't know which one i should buy. Which one of these are good for me to take or is there any other products i should take?
What is a good pre-workout supplement?
