Anyone try this or heard anything about this? people over at BB.com are goin crazy over it, and saying its just as good/ or better then RPM. Ive ran RPM for awhile and felt like the effectiveness diminished over time, maybe this would be something good to try.

ZAP is an awesome product.... absolutely amazing for energy. At the end of my workouts, I am not tired at all.. amazing intensity.

With RPM I didn't notice much fatigue and evergy levels were as high as they were at the start of the workout. I was kind of hoping for a increase in energy levels throughout the workout though. So how does Zap compare?
