Well..... It tasted good, it didn't make me shit mid workout like most other NO2 products, it did not make me feel like a crazed meth addict, I did not crash mid workout, and I seriously got the best pump I have ever had from a non-hormonal supplement. Seriously.
My first impression is I am blown away. It is not like jack3d in that in amps you out like a tweaker. Very clean energy. No RUSH like most over-caffeinated products. You can not "Placebo effect" skin tight pumps and vascularity, but I will update though just in case
