Pre-Workout Natural Energy Supplement Caffeine-free Nootropic Focus & Muscle Building Support, Sour Apple, Genius Pre by the Genius Brand

I use this before swimming my daily 2.5km and can attest to its efficacy. No caffeine means I have a normal heart rate yet it does give me extra endurance.

Love all of the Genius PREs but this one is hands down the tastiest of them all. I am an avid pre workout user and I've been lifting for years. I actually remember when pre workout supplements really became popular. I was hardcore into Jack3d but really who wasn't at the time? As I've grown older and gained more experienced, I've learned a thing or two about pre workouts and I've grown very skeptical of a lot of brands. After Jack3d was recalled, I started reading more about the dangers that DMAA presents and I got really confused as to why was marketed as a pre-workout. You had people dying and I think it gave a terrible name to pre-workout! Then N.O. Xplode rolled around and the scoops were 10 times the size of Jack3d. Hold on now.... You're supposed to get actual workout ingredients in your pre??? It all clicked for me about 3 or 4 years ago when Pre JYM came on the market and Dr Stoppani broke down what is actually supposed to be in your pre. It was like a light bulb came on and that's when I really started to research myself. I really liked Pre JYM for awhile but it was no different in the sense that I still built up a tolerance and it made me have a nasty dependency on all of the caffeine. Most people don't like the jitters and all of that caffeine dependency
