Disclaimer: I received a sample as part of my JackedPack to review for free. As always, all opinions are my own.
I got this in a previous JackPack but just got around to trying it. It doesn't have much of a taste, and I can't think of anything to compare it to. It doesn't really mix very well either leaving a in the bottom of my glass.
While this didn't give me any extra energy, it did spike my body temp pretty good. Usually I don't work up a sweat until later in my run or workout, and this time I felt hot and started sweat right out of the gate. I will say I didn't fatigue during my workout, and there was no crash later. Over all this was an eh.
