C4 Extreme is powdered energy. Harnessing unparalleled NO3 technology and exclusive ingredients including creatine nitrate, L-dopa, and xanthinol nicotinate, C4 Extreme is more advanced than any pre-workout supplement in its class, possessing the power to ignite your mind, muscles, and workout regimen, workout after workout after workout.

What is NO3? NO3 is nitrate, an advanced compound that delivers unbelievable muscle pumps and amplifies the effectiveness of every ingredient in C4 Extreme. Cellucor is utilizing a new compound in which NO3 has been fused to creatine to create creatine nitrate; according to a UCLA study, creatine nitrate is 1000x more water soluble than either creatine monohydrate or other creatine derivatives. Unmatched water solubility ensures better absorption and absolutely none of the traditional side effects of creatine supplementation.

You will have more energy than you ever imagined possible from a supplement. You will get that extra rep and complete that last set, detonating any previous strength, endurance, and physique personal bests.

Cellucor C4 is a well flavored and very basic pre-workout product on the market. Its a top seller because its a simple formula that works Period! A good dose of creatine nitrate for a pump, Beta-alanine for your workout performance and a low stim pre-workout that can be used to not build up a large tolerance. Steady streaming energy and a great product to stack with a non-stim for extra pump such as Hemavol or MAN body octane. I highly suggest this pre-workout to anyone who wants to get into the pre-workout game. This is a nice product that has tons of flavors!

Dizziness
Skin tingling

Ive been using C4 on and off regularly. Its been my favourite pre workout for a while now. It has all the ingredients needed for a great workout. It give me the focus, the energy the kick, the power for doing 1 more rep. I highly recommended anyone looking in the market for a pre workout drink to try C4, and fruit punch flavour. It mixes really well and tastes phenomenal.

The only problem I faced is my body gets used to it. Meaning after a few weeks of continuous use, even if i take 2-3 scoops before my workout it doesn't give me the kick I felt in the initial stages, so i have to remind my self to circle off the product from time to time.

Hi, I'm reviewing Cellucor C4 (the newer one, not the older with the 1,3.)I've had a lot of the big name preworkouts (C4, Craze, Jack3d(og), 250super pump, Assault, 1RM, etc.) Out of all the preworkouts, I liked c4 about 2nd best to Jack3d original (with the 1,3 dimethyl.) C4 provided a good burst of energy and a small bump in mental focus, though it wasn't anything compared to Craze which has insane amounts of focus... like nothing else.

I first took 1 scoop of C4, it did pretty good with just one scoop. I had a good amount of energy, some more stamina, and there didn't seem to be any unwanted side effects. Next time, I took two scoops and got pretty much the same levels of everything I had with one scoop, which was a bit disappointing.

I stayed on one scoop because I didn't get any more effect from upping the dosage, even after being on it for awhile.

Good product, would try again.

When I began lifting weights there were many days when I just didn't have the energy to perform at my top level while in the gym. I decided to start looking into a preworkout. After going over many different kinds I decided C4 by Cellucor was my best option. I Could feel the boost in my energy levels immediately! Pump, mental focus, and energy are all great with this product! The taste is amazing as well. I have tried several different preworkouts since starting with C4 but I always end up coming back to it. There are a few downsides however..........Tolerance builds up fast. This is one product that needs cycled regularly. Also there is a "crash" after the effects wear off. Over all though Cellucor makes a great product. 8/10 total rating from me

This is a wonderful product. C4 comes in 30 and 60 servings, not 45. and the max reccomended dosage is 2 scoops, not three. And also early version contanted 1,3d. i hasent contained this ingredient in a while. This is good stuff. I have used c4 and will continue to use it. thanks

Great Product, I have the 60 day supply, but I take 2 scoops which takes it down to 30 days, NO COMPLAINTS. Great workout, increased bench from 135 to 225 in 3 weeks. NICE. Highly recommend.

This Was an Amazing Pre-workout. It really gave me a ton of energy with out the jitters. 30 servings for only 24.99!? You cant beat that for a good supplement. I had noticably better pumps too.

Only negative is i took it about 6:30pm and it kept me up till close to 2am. I started trying to get my workouts in earlier in the day and it was much better, and could sleep fine.

Over All. Awesome Product by Cellucor at an amazing price.

Surprise, surprise, another "concentrated" pre-workout product. Of course, despite being highly potent and explosive, C4 Extreme claims to give you 45 servings but really only gives you 15 because you need to use 3 scoops to actually get a substantial effect. This is basically a Jack3d clone, with caffeine, 1,3 D, creatine, arginine, beta alanine, etc. This also has mucuna pruriens and tyrosine, but how much those will do for you remains to be seen. Either way, the best part about this is the taste, which is fruit punch; better than M5 but still pretty average. Kind of clumpy on the mixing, but not too bad. Energy was subpar unless the maximum dose was used, and even then I found myself tiring out toward the tail end of my workout. No big crash, but no big boost in strength. Also, it's annoying that Cellucor goes after other brands for using prop blends in the C4 Extreme ads, but then doesn't disclose amounts of many ingredients, such as 1,3D.

Physical energy		It gives me just enough energy to get through my workout without making me feel jittery or keeping me up at night.
Taste		As far as flavors go: I had samples of the blue razz and fruit punch.
Taste		The blue razz tasted like medicine to me and looks/smells like lysol.
Taste		The fruit punch tasted like Kool-Aid which is fun.
Taste		I tend to dilute it more than the instructions recommend otherwise it can taste too strong.
