Cellucor C4 EXTREME ® (A FIRSTHAND EXPERIENCE)
I need energy. My workouts are good, sure, but sometimes I’m tired. Sometimes the fear of a mediocre workout keeps me on the couch. Do they make something for this? I hit the supplement store in search. One shiny chrome bottle stands out--it reads, Cellucor C4 Extreme. This pre-workout is unlike anything I’ve seen--no proprietary blends and it’s a reasonable price. I’m sold.
I’m still tired but now I’m excited to see what this supplement can do. I hustle home, change, and pop open my C4. I scoop it in and I’m shocked at how easily it mixes—I hardly had to stir! The flavor? It's unbelievable! Like a pro, I pound the rest in under 10 seconds and head to the gym. A warming sensation radiates through my body--C4 Extreme is no joke. I am ready to crush.
Today is chest day. I’m giggling as I warm up—the bar feels like a toy and I’m scared I’ll throw it through the ceiling. I’ve never felt so confident, so strong. I’ve never been so focused. Did I say I was tired today? I don’t even remember. I explode through the first set and I’m shocked as I just set a personal record with ease. I want more.
Before I know it, two hours have passed. My training partner gives me an “I’m tired” look, but I talk him into a brutal burn out set. When I’m done, I stand up and look in the mirror. I’m more vascular than a magazine ad, more pumped than I’ve ever seen. My workout partner now begs for an end to this brutal session and this time I oblige. As we head out, I suddenly hear my training partner clear his throat. “I’m trying C4 Extreme tomorrow,” he says, quietly. I grin, thinking of all I just accomplished, and decide to simply state the obvious; “I know.”

The best pre-workout I've tried yet! review by Amy R.
I was going to give up on taking a pre-workout altogether because I couldn't find one that didn't give me that sick caffeine feeling.. or a flavor that didn't make me nauseas. I feel like I've struck gold with Cellucor C4 Extreme (watermelon)! No jittery shakiness that most other pre-workouts have, and it actually tastes delicious. I can't wait to try another flavor!
My favorite pre-workout by far! review by Bryce S.
Take this before my hard gym days and it gets a great pump going, really helps power through heavy sets. Would really recommend green apple and strawberry margarita flavors.
An awesome product. review by Ruben M.
The best pre-workout I have had no joke. I felt the pump from the first scoop. There is skin tingling but you get used to it. Great focus in the gym. Tastes exactly as it says. Delicious & mixable.
Pretty good flavors, great results! review by DutchessofWonders
This is the first pre-workout I've ever tried and have converted my friends who use other products. Definitely gets the job done! I am only able to use the orange flavor, as the others are too sweet. So far I've tried Orange, fruit punch, & strawberry margarita, but I'm just about to give the watermelon a try. Can't complaint :)
C4 review by Flyyteach
Today was my first day using C4 and I am so very sick! I have been trying to get in touch with customer care all day; left voice mails, and making follow up calls. Although I have attempted to get in contact with someone, I have not had any luck. I am sure this product is great for some people, but not for me. I have been experiencing nausea and stomach aches all day. I even had to cut my workout short. I was trying to get in touch with someone to see if perhaps I was taking the supplement incorrectly, but I haven't been able to get in touch with anyone at Cellucor. The only reason I gave this product a 2 in quality is because it has made me very sick to my stomach. Everything else was fine.
PUMPED FOR C4. review by BKOZ
I heard so many good things about cellucor c4 that I knew I had to try it out for myself. I could not decide which flavor to try because they all sounded so tasty! I went for the icy blue razz, and it was such a good decision, the taste comparing to the fun dip blue powder, it makes you want to eat it right out of the container! I'm definitely going to be ordering more flavors to try, and will recommend it to everyone! :)
This product is awesome! review by Daralee
This product lives up to all the hype. I have used C4 while training for outdoor obstacle course races and also long distance cycling. I am able to stay focused and maintain energy for the duration of my workouts. Depending on the workout, I have stacked it with either the Alpha Amino or the BCAA. It works great with both those products. Many great flavors to choose from and it mixes easily with no "grit". I would highly recommend this product.
Excellent review by Mr.O
I was weighing in at 196 and now down to 159 lbs. I'm not the type that believes in supplements, but I decided to give Cellucor a chance to my new "lifestyle". I can tell you C4 Pre-work out has helped me out during my work outs. So far it has delivered explosive results! This is my first pre-work out and only! I highly recommend it!
Great kick starter review by Nashoboa
I tried this as something to help get me the energy I needed to head to the gym after a long 12 hour day at work. I have to say that it has gone above and beyond what I had expected. It not only hits fast it last for the two hours at the gym and after. I will be restocking next month.
favorite pre workout review by Ben
I started using pre-workouts about 2 years ago, and I've tried a few others-but always come back to C4 as a personal favorite. combining Alpha Amino and C4 I was able to have all the energy I needed for my workout, stay hydrated, and recover for the next workout. I strongly recommend this product.
Best pre-workout I have ever used! review by Jarod
The flavor is amazing, and the powder mixes instantly with water. I have never crashed post workout, and have constant energy throughout. I'd recommend this to anyone!
it sucks dont feel nothing review by kevin
I first bought c4 because I heard all the great reviews and decided to buy it I first took one scoop didnt feel nothing, then I took 1.5 scoops the next day felt nithing.i was mad because it was a waste of money it was my first pre workout abd u never drink stuff with stimulants so I took two scoops and nothing happens it sucks I felt the same
This product is AWESOME!! review by DP
I have used this product for a few months now and it works GREAT. I definitely notice the difference when I do not take it before a workout. Sustained energy for lifting and cardio sessions. Just do not take it later in the evening, you might have difficulty sleeping.
Greatest Pre-Workout, Intense Focus and Pump review by Ismael C.
Honestly I've drank other pre-workouts but none of them have had the effect C4 gave me, after a week of drinking it i felt the intense pump and focus making my workout experience the best I've ever had, i strongly recommend anyone who hasn't taken a pre-workout to try C4.
IT RAW review by Swaggy P
AFTER I TOOK IT I WAS SO HYPED. I WAS BENCHING MATT SNIPEFELLOW I WAS SO HYPED. #C4

I'm 18 years old teen girl .I like going skateboarding and I'm very passionate to be team manager for girls team in basketball. Very extremely excellent quality , mixability and good tasting flavour.. It's give focus , boost my level to highest point and helps my whole body alot..
Save your money review by Jillene
I had heard so many great things about this product that I wanted to try it myself. I ordered a sample pack and it arrived last week. I was a little nervous about how intense it would be so I started with half of a scoop. Nothing was any different than if I had consumed just water. The following day I tried a full scoop. Again, nothing. The following day I tried two scoops. Again, nothing. I have less than one caffeinated soda per day, and that is not even every day. I am average in size. I cannot think of any reason why this product did not work for me. I am glad I did not invest in a full canister! Back to the drawing board.
keeps me going review by skated99
LOVE IT. no muscle fatigue at all while working out and great taste! would highly recommend
Awesome Stuff! review by ant
C4 is a great product. I have hit my resistance wall, but once I stopped taking it for a couple weeks I am affected by it again. The taste is great it works almost instantly and I look forward to taking it before my workouts because I know the pump I'm about to get in. I've tried three other pwo and this one is really the only one the works for me!
good kick! review by Krystal F.
I love c4. I'm training for a fitness competition and I workout twice a day (early morning and late evening) and c4 helps me make it through both my workouts without feeling sluggish.
OMG IT IS AMAZING!!! THE PUMP IS AWESOME! review by Dinsel
When I first tried this product I could tell that I found my number 1 gym partner. it taste amazing and worth every penny. I find myself doing crunches and push ups in my office. The PUMP has me doing more than I could ever imagine. Thank you Cellucor for making the most amazing pre-workout product EVER!!! P.S. Watermelon is delicious (=
Amazing review by harrison
The best pre-workout I have ever had.The strawberry margarita is amazing
This was perfection review by the johnson
This product makes me feel like a god!
Great, but has side affects... review by Joey
I really like the product, but holy cow it made me sweat like a pig. I don't think that I've EVER sweat so much in my life. I was drenched. Anyways, I could tell that I had more energy, but I'm not sure if it's worth being drenched in sweat. I'm going to keep taking the product, but I don't know about all the sweating. It mixed great, but the fruit punch flavor could be better.
Best Pre-workout I've ever had review by Biffyfit
Best Pre-workout I've ever had. Tastes great and gives you explosive energy. Able to leap tall buildings in a single bound! <exaggerating... Seriously though this really helps kick ,my work-outs up a couple of notches. No crash.
Best Pre Workout ever!!! review by Jennifer
Love this product, even when I am tired i take this before my workout and it will give me the best energy I ever had with no jitters I have tried others and nothing has ever compare to C4 I can workout for hours and still have energy, I stacked this one with Cellucor BCAA and I get the best workouts ever.
Amazzzziiinnggg review by Lilmama
I received this product as a sample and after the first try, I had the best workout of my life. Now I'm hooked!!
Great review by Tbone
Amazing pump. Best pre work by far this and 1.mr are amazing
Delicious, Effective and Amazing PWO review by nfmejia
Best damn tasting PWO (pre-workout supp) and labeling is fool proof telling you exactly what you're getting and how much of it in each serving. I have had GREAT pumps, the beta tingle and amazing laser focus on this IRONCLAD PWO.
LOVE IT review by NIR
Thank for having it. Love it and it 110% working LOVE IT
Love it! review by Chris T
I have been using this product for over a year now and have seen very positive results. I have tried all but one flavor (green apple) and they taste amazing! The focus and energy I sustain throughout my workout is awesome, no joke either! If you are looking for a pre-workout product that works, I highly recommend C4!
First Pre workout review by Andrew M.
Fits every description of what a PWO should do. Insane energy and endless stamina. I started off with just 1 scoop even though im a big guy (6'2" 230 lbs) and still had tingles and massive pumps. Great job Cellucor! Im sold.
Excellent!! review by Tazer
I have tried many pre workouts and none of them compare to C4. C4 is the only one that has given me the pump and energy I need to get through my workouts. Overall Cellucor has the best products for anybody who works out!!
best preworkout ever review by muscle_man_123
I have been taking this pre workout for a couple of months it gives u the energy u need without making u jittery u don't loose all energy after a while u just keep feeling it all day and when your lifting weights u can feel it building your muscles.
Best pre-workout I've ever used! review by Roadkill
After doing research i decided to give this a try and i love it! Within 2 weeks i added 20lbs to my curls, and with one 30 serving container i added 2 inches to my arms! i recently bought my second container and can't wait to crack it open.
Delicious and does the trick! review by Em
I was hesitant at first since this was my first time trying a pre-workout. Cellucor C4 gave me that extra boost that I needed to intensify my workout. HIGHLY RECOMMEND!!!
C4's Power Matches the Hype review by Tony W.
The benefits of a solid pre-workout cannot be stressed enough. If you're looking for tons of energy to help you get a massive pump in your workout, look NO further. Cellucor's C4 brings all the energy and increased intensity with zero crash and zero jitters. Kick the energy drinks, save your money and pick up the real deal. I've had Orange, Blue Razz, Green Apple, and Strawberry Margarita, and they all taste amazing as I've come to expect from the minds at Cellucor. Don't miss out on the added edge C4 will give you.
Thee best ever review by Ya Boy
epic flavor, epic results. i love cellucor
Unbelieveably Powerful! review by Caleb T .
This stuff is the real deal. If you are looking for the ultimate preworkout supplement that will build you muscle and give you energy c4 extreme is the only way to go.

Great product !!!
Pump awesome review by Muscle man
This is a great product I did my weights in nothing flat fast an awesome I got fruit punch witch tastes like coolaid I will definitely be using this more.
The hype is true! review by Dro619
One of the best pre-workouts on the market! No doubt about it. After trying several of the hyped up pre-workouts on the market now, I can truly say this is one the best out there. Excellent quality that you get from any of Cellucor's products and mixability bar none with its competitors. If you want an excellent product with excellent flavor this is it! Search no more!!!
clean energy and great pumps! review by Rambo
ive tried a few other pre workout out there and this one is by the far the best tasting and most effective. it gives me clean long lasting energy and i am able to do more reps on each set. it helps me reach failure and even hold it for 20 seconds! which seemed painful nd stressful before. somehow i feel less of a burn after taking c4 and cuz of that i can do more reps and get bigger pumps by pushing each rep and giving it my all and when the next morning i wake up all sore and swollen, i know right then it gave me a great workout!!!
amazing product review by E.L Hewlett
This product has revolutionized the way that I work out and train. I tried the product around seven months ago and the amount of energy and focus that the product gave me has been unmatched by any other product. I take the cellucor creatine and BCAAs as well with this product and I really believe and trust in this brand. I would recommend this product to anyone.
Simply one of the best! review by Ptoku
While back when a friend of mine told me about C4 i honestly was skeptical. After looking into it i tried it. I love this preworkout. First it tastes super, probably best tasting preworkout ever ( i love watermelon or green apple its like sippin on a jolly rancher). second i love the tingly effect that pumps me with a huge load of energy. Third is that i dont crash while doing a workout.
The BEST ever review by TrackStar
As an Olympic runner this supplement. Gave me more than enough. Energy. And strenght.. its the best but by far the craziest
Best Pre-Workout available!! review by Superman542
Great product!! It does just what is says it will do! Cellucor products have been the best with shown results. While using all their different products through my weight loss journey and body transformation, I am glad I have chosen their products to assist me in everything!!
GETS YOU HYPED, EVEN ON YOUR DOWN DAYS!!! review by LHS - Jerison
This product is 100.99% to work great, and boost your ability to workout. I love the flavor and the after taste and also the intensity of the workout is amazing!!
C4 is the ONLY pre-workout supplement I will ever use! review by Michael
I have used C4 for a few years now and I have to say -- I absolutely love it. Other products that I have used gave me the jitters and had a hard crash once they wore off. C4 gives me a great boost without the crash. Fruit Punch was my long-time favorite flavor until I discovered Watermelon flavored C4 -- it's delicious! If you're looking for the absolute best pre-workout on the market -- there is no substitute for C4.
Above and beyond expectations review by Tramples
I was skeptical to try something that claimed to be the best. I tried the fruit punch that I bought at my local costco. One scoop and it hit me. I increased all my workouts by at least ten pounds per exercise. The pineapple tastes like candy. One scoop pineapple and one scoop fruit punch and you get a great jolly rancheresque flavor. The mixing is easy! It dissolved as it hits the water. Thanks Cellucor!
You looking for razor sharp focus? You've GOT it here. review by Luis
Taking C4 Extreme is the best decision I've made, more specifically the new Mystery Flavor. They NAILED the "tropical" flavor and the product itself gives me the greatest boost and focus that I need at the gym. The recent unveiling of Cellucor products has me incredibly excited for what the future holds! KEEP THE GREAT PRODUCTS COMING!
love it the best pre workout formula ever review by fitness
Tried for the first time today, I was able to lift 15lbs heavier and my cardio training was through the roof.
Best Product I've Tried review by Q
Just like everyone elses reviews this product is amazing you give you focus and more umph in your lifting. Taste are a little sweet for me but remind me of jolly ranchers or the dip stick powder. First time using it made me really itchy but ah it works and I can work past an annoying itch. My favorite pre workout right here
Really Good! review by Alayna
It was definitely good. I'm a big fan of C4 pre-workouts. Of course I've only been using Blue Raspberry, Fruit Punch, and now Watermelon. I would like to try the Pineapple one. I've heard some good things about it!!
Best Pre-workout on the market review by Rachel
I have tried each flavor of C4 - each flavor is ON POINT! This pre-workout is the perfect combination of beta alanine, caffeine, & creatine. Highly recommend!
Focused and Motivated! review by Stephen B
Just started my 3rd week of a body transformation contest and I felt like I needed an extra boost. I decided to give C4 a shot and after the second day of using it I found myself doing more than my planned workout. I feel more focused and motivated than ever! Icy Blue Razz is a great flavor. I'm looking forward to trying the many other favors.
Smooth and the taste was great review by Brent
I didn't notice any grainy texture, the flavor was spot on and I couldn't be more excited to utilize this. Previous brands and flavors I was more resistant to using pre-workout.
THE BEST! review by Bret C.
C-4 was the first pre-workout I ever tried. Since then I have tried many others and NONE have even touched C-4 in all 3 categories. It taste the best, it mixes great and you get an amazing pump that pushes you through your workout. The Beta-Alinine gives that tingling feeling and you know its time to put some work in. I highly recommend this product!!
Best Pre-Workout Supplement ! review by Dante B.
One of the biggest problems with pre-workout supplements is the taste, but not with Cellucor's c4. This product gives great Focus, Pump, and the Energy needed to perform in the gym. Best pre-workout supplement! Don't waste your money on other supplements, buy from the best supplement company, Cellucor !
not bad review by cdot
you can feel the tingle in your skin a few minutes after drinking. other than that I really like the energy it gives me. Blue Razz is my favorite. Fruit punch has a weird smell and taste..
WOW! review by Rodger
I've never tried anything that compares. Years ago I tried something that was maxed out on Yohimbe that made me crazy. C4 Extreme is much less intense, yet much more than that product ever was. If you're looking for cutting edge tech for muscle growth, this is it.
C4 pre-workout review by Lray
This product amazes me! I am glad I tried this product. I have tried other pre-workout supplement in the past but nothing works..not even just a little result. I notice a huge difference in my workout from gaining strength and able to keep my strength gain even after I stop using it..And also helps me last longer through my workout in improve endurance and stamina. I would normally get burned out and fatigue after 1 1/2 hours of lifting heavy weights. But when I'm on C4, I feel like I can keep working out for hours and don't feel burned out or tired..My incline barbel bench press went from 185 lbs. to 245 lbs.!! I've been stuck on 185 lbs for couple years. I started to think that maybe it is the most weight I could incline press.. C4 help me break through that mold or plateau. It also helps me focus and concentrate on the weight.
The best ever!!!!!!!!!!!#1 review by Beast
I've tried many pwo, but this one really work it gives that additional push that help you to achieve that explosive workout that you want and till the end of your program........ Take this if you wanna train like a beast!,,.....
