C4 Performance Energy, Orange Slice Drink Mix, 200mg Caffeine, Zero Sugar, NSF (2 Boxes, 16 Sticks)

These are great for the cost. The taste is on point. It dissolves well in water (the clumping is not an issue) and it is just as strong as the canned version. It will require a bit of shaking, as it does not stay in a perfect powdered form while in the packs. The individual packs themselves are pretty strong and it takes some force to poke a hole in it, making it ideal to throw in a go bag with random items without fear of easily being punctured. I have gone out of my way to tell friends about this product. I am very pleased with it, and purchase repeatedly.

I love this, I get my energy and my water intake all at the same time. Taste great, they mix really well. Quality is excellent

Ive bought 3 double packs of the orange slice and every single packet the powder mix has become solid. I have to break the solid up which never happens with any other flavor. The strawberry watermelon and bombsicle have never hardened up and I would recommend those 2 flavors over the orange slice.

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 agree with others that said this product was clumpy/hard. The whole package is not powder but a clump. It takes a long time to fully dissolve it in water. Once dissolved it tasted fine. This is the Orange flavor.
