Mmm...didn't see much improvement until I stopped
on 3 May 2014
I was doing Crossfit and added this to my pre-workout. The tingling isn't unpleasant, but it did get me wondering what the biology behind the drug was - like the pulsing in your fingers if you take viagra - it's definitely doing something powerful! But is it good for you? And does it work?...I gave it 3 because for what it actually is, it is good value and the company is good. So if this stuff rocks your world, it's perfect. My review is really on performance...I didn't see any improvement in performance, even after a month...in fact when I stopped using it I felt more aware of my strength and pace than before, my feeling was I got tired quicker with less stamina when I was on it, but didn't see any improvement in my PB's...so I can't really recommend it for what it is purchased for. Given the tingling, I have stopped using it because it is clearly doing something to my body - but it isn't showing me a clear improvement. I did go a good month before stopping it's use.
