I was a major user of energy drinks. I'd drink anywhere from 5 to 8 energy drinks a week. When I came across G-Fuel (thanks to Dr Disrespect), I figured it was worth a shot. I've been using G-Fuel now for about a month or so, now. Definitely not over exaggerating when I say it has changed my life. The obvious health benefits of not having one of the mainstream energy drinks ruining my kidneys was one contributing factor to making the switch but the overall effectiveness of G-Fuel (and great taste) is what keeps me coming back. I've tried both the hydration and energy formula. Both are equally amazing and I'd recommend anyone to become a G-Fuel member! I've already pointed several friends this way and I'll continue to do that to prevent anyone else from wasting their money in the sugar dump the mainstream guys put out there.
