Does not produce tachycardia
Great, other caffeines caused a spike that in my case accelerated me excessively creating tachycardia. Very bad if you have anxiety. This one on the other hand I took it for breakfast and I had energy all day long, not only during training. I've even taken it at lunchtime and it hasn't affected my sleep or anything else.

Good value for money
The truth is that the supplement has a very competitive price with others on the market, the only thing that the prolonged effect is not very noticeable, yes you can see that it is not as sharp but nothing more, I still recommend it.
