Just wanted to leave a short review about my experience. I used to drink all kinds of different energy drinks to help get through work, to game, and generally wake up. I noticed I would get jittery and often have crashes with most energy drinks. The energy would be sharp and body focused almost like feeling too wound up. Gfuel doesn't have any of these issues what so ever. I get a Clear mental focus boost and feel awake and aware. I have tried over 20 of their flavors and havent been disappointed yet. Shipping is quick and reliable and the price cant be beat. Less than $1 per 16 oz serving when purchasing tubs! I would recommend Gfuel to anyone and have been!
