I've been drinking G Fuel for about a month now and it really works. It's not bad for you and you have so much energy to start your day. It's a great substitution for coffee. One thing I wish they would fix is that some flavors that are tubes are only available in tubes not packs, or vice-versa. But overall I love this product and I highly recommend to anyone who is looking for a healthy option for an energy booster in the morning.
