I love these. I have been an avid drinker since I found them in a local store and now can only find these ones on Amazon. I have never had a flavor I didn't like. They give me a nice pick me up without the jitters or anxiety or heart racing. The caffeine comes from green tea and gives me a nice noticeable boost that lasts and gets me through my afternoon workday. I haven't had any bad side effects. The pre-workout ones can make my face itchy from the beta-alanine. Kinda pricey but I try to catch them on deals when I can.

I will preface this with saying I do not use these before I work out, because the only time I do is at my extremely active job and if I have caffeine before that, I'll be bouncing off the walls! My poor coworkers have seen me make that mistake a few times. Now!! What I do use this for is a boost during school hours. I have adhd, and until recently it was entirely unmedicated, which meant I had to supplement with anything and everything available so I could function like a regular person. I'd drink these slowly over the course of a few hours, and I found their effects to be really helpful in maintaining equilibrium. Taste- Not nearly as chock full of that artificial sweetener taste as I was expecting. The citric acid really pulls its weight here, and the lack of artificial dyes helps a lot with keeping it crisp and delicious. I was surprised at how good it was. It was still sweet, yes, but not overwhelmingly so. Which is saying a lot, since I'm a person with an easily overwhelmed pallette. Energy- Solid 10/10, even over a long period of time. My blood sugar didn't spike, and I never got up to the level of jittery that haunts me with coffee from time to time, and over a few days of having one, I noticed that my energy in general was higher than it had been before. Keep- I noticed no change in the bottles I had in my fridge for months, and the ones I drank the moment they'd been chilled out of the box. Normally with drinks like these, the sweeteners get unbearably strong after some time, but I didn't have that issue here.

The taste is decent, and the 200mg caffeine provides a noticeable energy boost, perfect for a morning pick-me-up. However, the price per can is a bit expensive unless you catch them on sale. Overall, if you can find them on sale, Cellucor C4 Smart Energy Drink is a decent option for a good caffeine boost. I still prefer Rockstar or Monster overall.

The 12oz amount is the perfect amount for us. The 16oz sometimes partially goes to waste due to being somewhat more. The taste is great as well.

This is my new favorite energy drink! Love the flavor. Not too sweet like others I’ve tried. Gives just the right amount of boost to my day without any jitters.

Doesn’t blow my stomach, amazing delicious taste and energy boost

The taste of this juice is really nice what I love about it it’s really refreshing not too sweet my mom love them in all the flavors I’m definitely buying another one

I was taking this for several weeks now to try to improve my focus for studying, and it was doing the total opposite. Whenever i drink this I can't focus or even grasp the most basic concept. It also screwed up my memory and gave me lots of severe headaches and sleep problems. It also tastes horrible compared to diet coke or other diet drinks.

Carbonated

Solid choice, great taste and keeps you awake for hours

Delicious, good energy, please bring more flavours to intl prime shipping.

Not one of these four flavors is particularly good.
