I found this product to really shine after the second week, the focus element is really there. You become switched on and ready to go. I felt much more sharper like nootropics work and make you feel. The L tyrosine dose seems to be bang on.
With my caffeine tolerance being high I didn't really notice it, so me personally I wouldn't use as a pre workout but this work stack well with extra caffeine or some of supplements needs stackable pre's/pump formula.
If your drinking energy drinks every day then is a good replacement and for the price of an energy drink ie a Monster or red bull you are getting extra good quality ingredients like the lions mane, alpha gpc and L tyrosine it's worth the money.
