"Best tasting energy drink"
Had them all, still the best tasting, cleanest tasting and most natural of all the energy drinks. Difficult to find at retail so Amazon is where I have to go to get it. Amazon also the best price with efficient delivery.

"Great Energy Drink!"
While I really do like Red Bull, it's really nice to have an alternative like GURU when you're looking to switch it up a bit.
Both the energy effect and taste are at the same level as Red Bull (it doesn't taste the same, just that it's about as tasty). It does taste a lot better than Rockstar or Monster.

So, if you regularly drink Red Bull but want to switch it up, this is a good option.

"Gets yoU Ready for yoUr activities"
With a formula of all-natural ingredients and a quite flavorful taste, GURU Energy Drink has carved a nice niche in this crowded field of products. The 8.3 ounce can is great to pack in a gym bag or satchel and certainly can be used during those stressful work days. And the cost for the case is certainly a huge plus.

"Best Energy Drink Ever!"
I found out about this energy drink by googling the web for energy drinks with only natural ingredients, because all other energy drinks that I have tried like Red Bull, Sobe etc. have lots of vitamin B and caffeine which increases metabolism and makes me lose weight, which sounds like a good thing but I'm naturally thin and already have a high metabolism. Guru was the perfect answer, it's not packed with vitamin B's or synthetic caffeine and so it doesnt give you a crash. It takes about 20 minutes to kick in and when it does its a very clean and smooth energy. It tastes a little fruity with little carbonation, and it has a good after taste, very unique. I take one in the morning before class or work sometimes and it works great with no crash at all. It's perfect to take right before going to the gym. I tried taking red bull before going to the gym, and it wore off quickly and drastically, made me exhausted. Try Guru, you wont regret it.

"Finally, something that works."
I have searched everywhere and tried everything to find a product that works. I have used everything, 5-Hour Energy, Red Bull, Monster and all of those fad drinks. The problems with those products are:
-The sickening artificial ingredients like Taurine (which is a constituent of bile and has not been proven to do anything useful for an adult)
-The high calories from HFCS or oppositely the afewul taste from artificial sweeteners
-Over abundance of ingredients that cancel each other out (like caffeine's depletion of vitamin C in the body)

What makes Guru so good? Well, the first example is that I have had insomnia for 8 years while trying to write my first book and training for triathalons. I need energy and concentration more than the average joe. The other drinks either shoot you up for an hour and then you crash, do nothing, taste too bad to drink, or your body gets used to them quickly. Instead, I have found that Guru:
-Is a gradual increase of energy, mostly mental concentration and awakeness instead of getting the jitters or a Niacin flush like with other drinks
-It lasts hours with no crash
-No artificially added vitamins, sugars or caffeine
-The sugar is natural (from organic concentrates) and will not make you crash like HFCS, the caffeine is natural as well
-Tastes wonderful!

I'd recommend this to anyone.
