Thanks, Matt C.
I´m not a big fan of stimulants. I might have a cup of coffee in the morning to get me going and to help me go to the restroom but 9 times out of 10 that´s decaf.
If I feel the need, especially at the end of a prep, I use 1/2 serving of Animal´s FURY. That´s 175mg of caffeine. Honestly, I drink it more for the flavor at that point. The green apple is awesome.
If your nutrition, sleep, hydration and salt intake (!) are on point you should have all the energy you need.
I´m too proud of myself to rely on a stimulant product to get shit done.
