C4 Performance Energy, Variety Pack, 200mg Caffeine, Zero Sugar, NSF (3 boxes, 24 sticks)

I love the taste of these and the ease of just opening the packet and pouring it in my water bottle. They give me the energy level I need to make it through my day and so I can stay hydrated in the Florida heat. They mix well in my water I just pour it in and shake the bottle real quick and there is no clumping. To me they are a good value for the money and I drink more than one of these a day to keep my energy up and to stay focused and it works.

Love the ease of use. A bit weaker than concentrated bottles but I do not find that to be a bad thing.

The media could not be loaded. Bought these packets because I've bought them at Walmart before and they were great. They taste better than the regular canned C4. I bought 2 boxes. Upon opening the first box I realized that all 8 packets were hard as a rock and no longer a powder. Figured that stuff happens and we'll take a loss on that box. Next day, I opened the 2nd box and the same thing had happened. I don't know if it's moisture getting in the packets during the manufacture process but it's definitely not making me feel great about buying them from Amazon again.I'm sure that not all of the packets are like this but you should know there's that risk when purchasing. But if you get a good box, they are amazing!!!

This flavor is a little chunky but taste amazing. Would be 5 stars if it wasn’t chunky. Would still recommend because still dissolves fast

This pre-workout has quickly become my go-to for every gym session. From the first scoop, I noticed a clean, sustained energy boost without the jittery feeling or crash that comes with some other formulas. It kicks in fast—about 20–30 minutes after taking it—and keeps me locked in through even the toughest workouts.The focus it gives is incredible. I feel dialed in from warm-up to cooldown, with better endurance and that extra drive to push through those last few reps. Pumps are solid too—my muscles feel fuller and more responsive, especially during high-volume sessions.Flavor is surprisingly good (I went with Blue Raspberry), and it mixes easily with no clumps or weird aftertaste. I also appreciate that it’s transparent with ingredients—no proprietary blends, so I know exactly what I’m putting in my body.If you're looking for a reliable pre-workout that delivers energy, focus, and performance without the crash, this is the one. Definitely a 5-star product in my book.

This is by far my favorite flavor of C4 and they were just getting way too expensive in the stores on the way to work, even with sale prices.So when I saw these I was wondering how the flavor would translate into a non-carbonated drink but I have been really pleasantly surprised so far.The directions recommend adding 1 packet to 12-16.9 oz bottle of water for full flavor and 200 mg of caffeine but I have been trying to stay more hydrated lately so instead I have been adding it to a full 32 oz Quart jar with a drinking lid attached and I would say that the flavor is still just as potent and tasty as your basic sports drinks.So now by drinking 2 of these per day I am staying hydrated with an extra 32oz of water and still getting my 400 mg of caffeine at half the price!!

No anti-clumping ingredients? Every single one of my packets contained a giant clump of mix at the bottom. Tried to break it up and mix it, but was still left with large floating chunks in my water bottle. What a pathetic waste. The taste was good, except for the clumps. Celsius and Fast Twitch packets I’ve bought in the past did not clump.UPDATE: Post customer support, I received a full refund. I upgraded my rating from a 1 to a 3, due to the powder still not mixing quite as well as I would have hoped, based on the blue flavor that I also got. Other brands dissolved quickly and completely, unlike this product.

Tastes just like the regular c4 in a can but way cheaper.
