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

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.

I've never tried the canned C4 before, and I've been looking for some energy drinks that aren't canned, due to tariffs.I have always had a habit of using one water flavoring packet to 32 oz (about a liter) of water. This The C4 is pretty good with this ratio. It's less syrupy...or super sweet the way they all tend to be when mixed with 17 oz (a bit over half a liter.)I, personally, don't really have reaction to caffeine, at least it doesn't keep me up at night (I'm sure it still affects my blood pressure.) One thing I've noticed, since I tend to sip throughout the day rather than down the drink all at once, is I do have to shake/mix it up before I take a sip if it's been a while (I don't think the caffeine fully dissolves in the water.)All three flavors are delicious.Personally, these are a great substitute for buying canned energy drinks...for the foreseeable future.

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!!!

Pretty Good

I could get this price for 24 cans at Costco. But the convenience of ordering here, I opted for these packets.For someone who prefers the cans, as most drink mixes like this make my kidneys/bladder more active, I am pleased with these. They taste great even mixing with 16-24oz water. Very convenient, as you can take a handful of them anywhere and just add them to water.While the C4 tri-stim are too strong for me, these are comparable to the regular C4 energy drinks. If you are used to tri-stim, these won't be as strong and may be disappointing.

Perfect for a quick boost. Mainly bought to bring on vacation before working out in the am. No tsa issues with the packets

To be honest, this just makes me sleepy an hour later. It doesn't provide the same clean energy that lasts without the crash that the tubs and cans do. I'm not sure why. There must be something else in this that is causing that. Something that doesn't exist in the tubs and cans. Unfortunate, because this isn't a bad deal. It did not arrive clumped the way others have complained about. Maybe they just got a bad batch, who knows.

Haha if ya can't stop drinking energy drinks and sick of the cost these are great replacements
