Slave to the needle
A cheap great pre work out is 400mgs of caffeine in tablet form and around 300mgs of DMAE. You can buy both in pill version. And it works damn near as good as a pre work out. Those pre work out drinks are nice but when you think about it. They are a rip off. You can just buy the bulk ingredients for cheaper.
Go on supplementwarehouse mad. They have a bunch of whole jars of "knock off" pre workouts for like 8 bucks. I have got a c4 knock off with same ingredients for 7.99.
