This product increases my endurance and its tingling effect gives me a little buzz that makes me push more weights. I recommend to give it a try, since not everyone likes its tingling effect.

New to all this, just started using it few weeks back and i can say 100% it helps A LOT with my work outs (i take it 30 min before with Creatine) Only question, how many calories does it have ??

3weeks in lov this stuff deff givs u focus .....get it.lookin forward to the results I know r comin

I've used this product for around 4 months on and off due to down season in my sport, while I used this I noticed a difference in my performance and I liked the tingle it gives, it reassured me that something is working somewhere, however, I have more recently started using it properly at the gym, with great effects as a pre work out long side BCAA 4:1:1, CEE and Taurine, a great combination and I can feel my mental game increase when I feel the tingle now, knowing it's working inside my system. I would always recommend MyProtein's products.

Great for endurance sports, but i do not like the tingling effects. But it works
