I like ripped fuel for weight lifting, T-Rex for cardio. Sometimes, all I need is a can of diet coke for that needed pick-me-up. I try to stay away from stimulants as much as possible though.
Is this still manufactured. I tried Ultimate Orange once and was impressed. It drastically reduced my perception of fatigue in tandem with stimulation. I could max out and discomfort was barely perceptible. I just couldn't move the weight further.
I like 1-2 thermorexins, 12.5 mg of ephedrine sulfate, 1-2 neurogenix, and 2 Levorexin taken on an empty stomach and washed down with Sprite Zero. I take this before Brazilian Jiu-jitsu sparring and can go for 2 hours flat out with only minimal breaks between matches.
