I thought Stimul8 compared very well in terms of energy. It goes head to head with DMAA (1,3 dimethyamylamine) based pre workouts like original Jack3d. I had awesome energy for a great price! That said, I did crash before my workout was over. It was partially my fault as I worked for a while after taking, but definitely doesn't last as long as some other pre workouts. Also, if you want a good pump this is not the pre workout for you. It contains little to no nitric oxide boosters and is the definition of an "ultra concentrated" pre workout. However if you want great, non-dmaa or non-dmha energy at a great value, Stimul8 is the pre workout for you!
I received a sample of this stuff and definitely the strongest stimulant that I've tried since the old ephedra days. I had the best workout ever, but keep me up. Hands down the strongest PWO.
Only preworkout I actually feel. Made good strength gains. Good energy.
I unfortunately ordered this preworkout and it was a complete waste. Didn't give me the usual buzzing energy and tingle of most preworkouts it just made me sick. Cold sweats, feeling tired and gave me a headache. I ended up taking a week off from working out and threw this garbage away. DO NOT BUY
Received a few samples online. I'm pretty stim tolerant and have used preworkouts such as Jack3d, 1mr, Craze, etc. for the last year. This preworkout made me feel uncomforable, even at the recommended dose. I felt very agitated and anxious which I have never experienced with any other preworkout so far. Could feel my heart pounding in my chest (increased contractility) and my pulses were bounding. Lots of perspiration despite feeling cold (cold sweats). I experienced no noticeable increases in strength or endurance. I even yawned a few times during the workout which is very unusual for me. Second sample gave me a major headache, which plagued me off and on for the last month. These headaches increased upon exertion and negatively impacted my workouts. This scared me as I rarely experience headaches to begin with. Thanks to Stimul8, I'm taking a break from the stims for a while. Glad I got to sample this formula before comitting to a whole container.
