Cellucor C4 Ultimate x WWE | 300mg Caffeine Sugar Free Energy Drink | Knockout Nectarine Guava | 16oz (Pack of 12)

I love c4 because it's good for your mind. Awesome flavors. Thank you.

It's delicious. I just wish they sold it outside of Amazon, but it's proved impossible for me to find near me.

Is really tasty. Slightly bitter aftertaste, but it seems to common to the "Frost" and "Ultimate" lines. Would recommend as the aftertaste isn't overwhelming.

Me encanta el sabor, cero azúcar y te da la potencia para entrenar. Definitivamente lo recomiendo como pre-workout

This is the worst tasting energy drink I have ever had. Not sure if it was a bad batch or mixture. The quality was terrible. I was really disappointed in this product and had to pour out half the case because of how bad it was as I did not get the value for my money.

Just recently tried a case of the new C4 Ultimate Energy WWE Knockout Nectarine Guava and it has instantly become my new favorite C4 flavor! I’ve been drinking C4 for several years and occasionally use it as a pre-workout but mostly drink them for when I’m feeling sluggish and want a reliable energy boost. This new flavor, the taste is a perfect combo of nectarine/fresh citrus goodness with what tastes almost like strawberry and pineapple together. That strawberry/pineapple is no doubt the guava flavor and I’m telling you it meshes beautifully with the nectarine taste. It’s so easy to drink this stuff that I find myself finishing a 16oz can almost too quickly. On top of the amazing flavor and taste, the fact that each can contains 300mg of clean caffeine, no sugar and no calories makes this the exact kind of guilt-free energy drink I like to stock at home. It always delivers a reliable and noticeable increase in my energy and I never get the unwanted jitters or unpleasant overloaded feeling. After a couple hours and the energy boost starts to fade, the come down feels subtle, not rushed and with no drastic crash feeling whatsoever. Honestly, I’m not sure how C4 always manages to create the perfect energy drinks. I’ve tried so many different brands and no matter what I always find myself coming back to C4. In this case, it’s because the new Knockout Nectarine Guava tastes amazing but it’s really due to the fact that their products always deliver the cleanest and most effective energy I’ve ever experienced in an energy drink. If you’re looking for a perfectly crafted energy boost beverage you should seriously consider trying out this flavor. If you appreciate the taste of fresh and perfectly ripened tangerines with a tropical twist of guava this knockout nectarine guava is guaranteed to hit the spot and leave you feeling refreshed and energized.

I don't really care for the marketing or branding of this product, as im not a 'WWE" fan, but this drink actually tastes pretty good so I'm happy to give it 5 stars. I usually drink a few different varieties of Monster Ultra (zero calorie) and this product tastes similar to the guava version of that. There isn't a noticeable fake sugar taste like so many bad energy drinks have - this one actually tastes real. I haven't had a "C4" energy drink before but if the other varieties taste as good as this one I'll have to try them out. As far as the 300mg caffeine claim is concerned, I wouldn't be surprised if the real number was a lot less than that. I certainly don't feel much more energized with this drink than with any other. Pleased with this order. If you enjoy the many varieties of Monster Ultra you should give this one a try as it is also zero-calories and the taste is just as good.

I thought I have high caffeine tolerance so I started drinking one of these around 5pm and spaced the whole can throughout the night... and couldn't sleep til like 7:30am the next day!! I didn't think it would be that bad. Previously, I drank a can during the day (different days) and slept only a bit later than normal. This one instance is probably affected by other factors, but I am NOT repeating that again. I don't wanna be awake til the next morning! Other than potency, the taste needs getting used to as it isn't one of my go-to flavors. It's not bad but not my favorite and the flavor didn't become a favorite after this set either. As for value, you get a lot of cans for the price and the effect works well for me. Definitely 5 stars for keeping me awake when I need and don't need it.
