So I told my coworker that red bull wasn't doing the trick anymore and it was getting harder for me to stay awake on our night run. This man gave me a powder and told me to mix it with some water and down it... I drank that shyt during my run, and not only did I become wide awake after struggling to keep my eyes open, but I had the strong urge to pull over and knock out some push ups. He sent me the info after we got off and turns out it was Preformx Ion from GNC.
I recommend the shyt out of this if you need motivation to work out or just want a replacement for Red Bull.
