What do you think is the best pre workout that you have tried that doesn't make you too jittery but gets you HYPED up. Recently I had a few samples of bang pre workout and loved it. But I'm wondering if it was just the large amounts of caffeine in bang that hyped me up. Is it really worth buying such an expensive drink? Or would it be more beneficial to just buy some aminos, L-carnitine, beta-alanine, etc. and take a caffeine pill with it.
Has anyone every tried to blend their own pre workout or tried caffeine pills?
Also, the reason I didn't mention L-arginine for the "do-it-yourself" pre workout blend, is because I have read a lot of research saying L-arginine doesn't really vasodilator your vessels anymore than just exercising would!
