Personally i'm really going to miss DMAA once it goes for good. I'm in the gym at 6.30am and i need a pre-workout supp to get the most from these early morning sessions. I have always used Jack3d and find it to be brilliant, and at under £20 for over 6 weeks worth, its about as good value as pre-workout supps go.
As an experiment, i used a free sample of a new pre workout supp which DOESNT have DMAA in it and it was rubbish, i actually went back to bed!
What Jack3d does for me is not only wake me up but it motivates me. I dont know how, but it does. I've used it on a non-workout day before and stuff i was able to cross of my to-do list was insane!
I'm going to be doing my best to stock up before it disappears entirely.
