I’ve tried those 5 hour energy drinks and I don’t feel a thing. What is the best kind of energy drink that really works, gives more energy to exercise longer? I want something that really works. Any idea what I should get? I don’t wanna spend too much money on whatever energy drink that really works, I just wanna get whatever energy that really works for one or two weeks and by then after all that good workout I should have the energy to be able to exercise without those drinks. Just need a good start up.
