I don't see any reason why or why not. I never got anything out of Ripped fuel myself, now Beta Lean and some of the other fat burners, they work well on me, but I come down on them quick and feel like shit. BUt if it gives you energy, and you like it, hell go for it. I think with your stack you will be fine, the ripped fuel I don't think will do anything, but stickly for energy, hell yeah, if it works. Be sure it isn't the "gear" that is giving you the energy. When I do test, I can't sleep at night and wake up with 1 hour of sleep and feel the same as when I went to bed, all full of energy.
