I've been on a 10 days or so now. I'm doing judo, solely. The bottom line is that I can outmyself pre-Cre02, and most others in the dojo (fitness, not technique). Everyone else is sucking air, and I'm ready to go. Recovery from bouts is VERY fast. Strength is up, which helps in grappling immensely.
I get no energy from it, mental or otherwise. It's purely increased oxygen uptake or more efficient oxygen use, and more ATP. But it's VERY impressive. It's better in that respect than Body Octane. For pure performance, it surpasses VO2 and , though those two have benefits outside those of CRE02 and are very valuable in their own right.
I have noticed that I've been less fatigued daily. Sundays I run my coffee booth at the local farmers market, and I'm running from 6AM-4PM. Normally I'm trashed by 4PM, the action is non-stop; I'm selling product, which is a lot of explaining, talking, all the while brewing cups, making change, etc. The last two Sundays, I've been able to do stuff after; I took my daughter to the park, and ran alongside for a couple miles while she learned to get herself started on her bike. I felt good. Adaptogenics at work?
is different. I get a nootropic buzz, joint relief, vascularity, libido, and increased performance overall. It's a whole lot of good in one bottle, and I don't think anything else provides as much as effectively. I didn't lift weights with either, so no comment on that. But for pure ragged-edge, push the limits, intense cardio that is a mix of aerobic AND anaerobic exercise, Cre02 is the ****.
Cycling Blue Gene and Cre02 would likely be a wise idea for high intensity endeavors.
