C4 Review review by AJ

This is a nice improvement on the old formula. The older version of C4 seemed to be a hit or miss for me. I have had nothing but good workouts with the G4 version. 1 scoop gives me the alertness and extra boost I need to get started on my workouts but for me 1.5-2 scoops really shines. The full dosage of beta-alanine in 2 scoops really helps to power you through your workouts. Not sure why but C4 seems to give me a lot more tingles than other products containing the same amount of BA. For me that's a good thing cause it tells me its working. Tastes and mixes just fine, the strawberry margarita flavor was nice and refreshing.

Great Product! review by Trevor H

Cellucor did a great job on this pre-workout! It gives you the right amount of boost you need to kill your workout. A big upside is also the variety of flavors! You can never get tired of the same pre-workout taste!

Great Product review by Meggs

I have struggled for years with workout supplements that taste horrible. I use the strawberry margarita flavor and it tastes better than Koolaid. Drinking it is enjoyable. As for its performance, I am able to do twice as much as I normally was able to, without tiring. I cannot take it late at night because it prevents me from sleeping.

Great but not noticing the difference review by Howie

I've been using C4 for over a year now and it's my go-to pre-workout (2 months on and 1 month off it). The current review applies to both the new and old generation: Great pump and mixes real well. Got an extra few seconds w/ both my ATP-PC system and C4. Thanks again for the hookup.

Best Pre-workout I've ever tried review by Jacob

Mixes great, tastes top tier, gives you that extra push. No stomach upset at all, no headaches. The only negative was the tingly feeling from the Niacin (I think it's the Niacin). I just dropped to 1 scoop pre-workout, and stayed on that for 30 days before moving up to 1-1/2 and then 2 scoop if I thought I needed it, And no real issues with tingling. Drink extra water, and you'll be fine. C-4 was how I was introduced to Cellucor, and it's a great gateway product to the vast offerings of Cellucor. It's truly a flagship staple that should be in everyones workout supplement stack. Give it a try, it's great for pumps, and boosting strength during the workout. I mix it with Fruit Punch Alpha Aminos sometimes, and it tastes really good. If it works for you like it works for me (and all of my friends that use it) You will be completely satisfied.

C4 Gen4 Strawberry Margarita review by Fatguymind

II got a tub of the New C4 G4 to try out thanks to Cellucor and it is quite the improvement over the last formula. The new formula isnt drastically different but the right changes were made and the addition of Teacor apparently was another good choice. The effects of the new formula is much great than the last. More endurance, mental focus and the delay of lactic acid build up. The flavoring is still awesome. So for people that liked the last formula and or stim sensitive this is definitely worth a try.

Great Upgrade from the previous formula! review by DFucinari

I was so excited when I found out that Cellucor was creating a new line, and I cannot thank the Cellucor team enough for giving me this awesome opportunity to try the new C4! The old C4 was my go to pre-workout product for a long time and this new formula is an upgrade in every way. I take one heaping scoop about 15 minutes before my workout and it lasts me my entire hour long session. Compared to the old formula, I feel like this one hits me harder and faster and lasts longer. No product gives me energy like C4. I love the smooth, consistent energy that this product gives, no crash and no jitters. The pumps are awesome. Endurance, and vascularity are also amazing. All of these factors give me insane drive to kill my sets and lately I have been having some of my best workouts yet. I have been using it for about 3 weeks now and I do not need to take any extra scoops, which is nice for the value of the product. Nearing the end of a tub of the old C4 I would usually have to increase my dosage, but not with this new formula. I have the Blue Razz flavor, and while it is slightly different than the old flavor, it still tastes great. I mix it in only about 5oz of water so the flavor is strong, but thats how I like it. I had high expectations for this product and it did not disappoint me!

You can definitely notice the improvements made. Flavor is a lot more natural and smooth. Dissolves in the water almost instantly now. New stims feel smooth and clean. Great pumps and energy in the gym. Cellucor always comes thru with quality. Looking forward to trying the rest of Gen 4

Next Gen Offers New Kick review by WashboardSlim

I was recently sent a sample package of Icy Blue Razz C4 (Gen 4) to review and today was my first time trying their new blend. All I can say is WOW. C4 was the first pre-workout I ever tried, and after some time it seemed to be a case of diminishing returns. I worked my way up to a solid two scoops at a time before I finally switched brands (as is the problem with most preworkouts). This new formula, however, does not disappoint. I decided to take it ~30 minutes before my workout and I immediately noticed two things: it mixed incredibly well and tasted MUCH better than previous iterations. In terms of effectiveness, I give it a solid 4 stars. Could it be stronger? Of course. But compared to other pre's on the market right now, C4 holds its own. Especially for the price. Long story short, I highly recommend this product.

G4 C4 Scores! review by Wittig Works

I've been using Cellucor products for the last few years with great results for me and my personal training clients. C4 pre-workout is a important part of my pre-workout ritual. This new G4 formula is so powerful I had to back down to 1 scoop from my normal 2. As always it taste great and gives me that extra push to get that one last rep. -Wittig

Best Tasting (& Working) PreWorkout review by Ronald

Mixability 9/10: I stir 1 scoop into 5-6oz of water, it stirs in easy enough but leaves some particles behind/floating Taste 10/10: I'm not sure how, but somehow they did it: they've made an incredible tasting product taste even better. Generation4 C4 Icy Blue Razz flavor taste even better than the previous formulas flavors Formula 10/10: I like this new formula because of the increase in caffeine and the addition of a new ingredient, Teacor. Despite the additional caffeine I don't feel extremely high in energy/jittery; it's just right and makes me feel good. Energy and Focus (10/10): I felt a steady rush of energy. Which, unlike the old formula, was present throughout my entire workout. I haven't felt any sort of crash during my workout or post workout. Yes I've been tired, but it wasn't an energy crash tired it was a muscle are exhausted tired, Overall: Comparing the new and old formulas I must say the new formula has noticeable differences, which I like a lot, and I have had the most excellent workouts. I had high expectations for this new formula and, as usual, Cellucor did not let me down. They definitely exceeded my expectations, as always.

Excellent product for anyone looking to improve their workouts! review by KentMarshall

When it comes to pre-workouts C4 has always been my go-to product! The new Generation 4 formula is no exception. The new formula mixes well with water with no residue left behind. I tend to drink my pre-workouts fast, once consumed though, there is no need to wait. the new formula worked for me in under 15 minutes and then I had unwavering energy and focus for the remainder of my exercise. The pump and strength gained over the course of two weeks while taking the C4 was second to none, and in fact had the results that are generally gained from taking 3-4 separate supplements. Along with excellent taste and the addition of TeaCor, a new ingredient with the Generation 4 C4, this product is the only pre-workout I ever plan to use!

next level C4 review by masher230

Let me say that C4 has always been one of my favorite Pre-wo's. through re-formulations and new flavor introductions the quality has never wavered and the new Gen 4 is no different. i got the opportunity to review the Strawberry Margarita flavor and it is delicious! i found my sweet spot at a little less than 2 scoops and like all C4's of the past it gives you everything you could ask for in a Pre...longlasting energy, great focus and superior pumps. this is another solid addition to an already superior product. great job Cellucor...awesomely effective.

My new favorite review by Star

Who thought Cellucor could improve on my favorite product? This new generation of C4 has it all. I take it in the morning when I can barely keep my eyes open. By the time I hit the gym 30 minutes later, I have crazy but balanced energy, great endurance, and increased strength. Thanks so much Cellucor for always raising the bar on supplements. I recommend this product to all my fitness fanatic friends.

Not What I Expected review by Hector

I got a tub of C4 from Cellucor for free in return for an honest review so here it goes. To start off, the powder was easy to mix with water and the taste was great too. I sort of expected to get pumped or something but I didn't, even after waiting the recommended time which I used to stretch. As far as getting pumped goes I never out of all of the times I tried it felt pumped. I did notice however that I wasn't as tired as usual after a workout. Usually after a workout I don't feel like doing much but since I've been taking C4 I tend to stay up to do some homework or study or something. I am still waiting on a product that legitimately gets me pumped. C4 will do for now.

NEW C4 is GREAT review by Kels

The New C4 Generation 4 preworkout is AhhhhMAZING. I already loved and have thought Cellucor's preworkout is the best. I tried the new re-vamped C4 and I could definitely tell the difference. The added and changed out ingredients definitely gave me more longer lasting energy and it was exactly what I needed. I tried the orange dreamsicle.. I wanted to try something different and it was a great change! I LOVE the flavor orange so having it in my preworkout drink was awesome. It mixes perfectly too. My husband as well loves C4 and could tell the different in the new product. What he pointed out was that it gave him a better focus, drive and motivation! GREAT stuff and I am so glad for it! HIGHLY recommended!!!

Love the new Gen. 4! review by gmach

wow...i just found my new favorite Pre-wo! Cellucor generously provided a tub of their new Generation 4, C4 for me to evaluate and review...big thanks to them. i was given the Fruit Punch flavor and following label directions i mixed 1 scoop in about 6 oz of cold water a half hour before training.. the C4 mixed up easily and almost completely and the Fruit Punch flavoring was much like Hawaiian Punch. im fairly stim tolerant so at this dosage my expectations werent too high. but i definitely felt the product...energy and focus were enhanced and increased pumps were evident. my next session i increased the dosage to 1.5 servings and was immediately treated to an outstanding workout! at 1.5-2 servings the new C4 will knock your socks off. energy is off the charts and focus is laser-like. ive been using G4, C4 for 3 weeks now and there hasnt been the slightest tolerance buildup like that which happens when using some Pre's. i gave the new C4 a 10/10 in both flavor and overall effectiveness. i can see myself using this product far into the future and would definitely recommend it to anyone interested.

I have always enjoyed C4, great pumps, mixability, and rush. The next gen series takes that current formula and brings it to another level. It mixes clean in your shake, no grit, no foam.

Awesome new version of C4! review by VegasRocker

I received this as a sample from Cellucor and I have to say it did not disappoint. I am new to C4 but have used all the traditional pre-workouts on the market. I rated my experience in several categories. Mixability: This product mixed very easily with just a few swirls in a shaker cup. No grittiness or floaters in the cup. Taste: Cellucor shines in this dept. Strawberry Margarita was like drinking a desert. Other PWO's are nasty and have to be gulped but C4 actually made me look forward to sipping it. I know I can't drink it all day but wish I could. I checked out their other flavor choices and all I can say is WOW. Effectiveness: I felt the tingles and rush of energy within 10-15 minutes of drinking and it gave me an extra push in the gym. Bigger pump and more strength. The best part was no crash. They added TeaCor and so far, that looks like a solid way to differentiate this from other pWO'S. Ingredients: All solid proven ingredients in good dosages. They use Creatine Nitrate which I believe is easier on the stomach then monohydrate. No cheap shortcuts here. Overall, great product. I am super pumped to try other Cellucor products like Alpha Amino. Great job Cellucor!

Love the new formula! review by JLassiter83

I didn't think this product could get any better but it has! I tested the Fruit Punch flavor, which I have tried before but this version seemed less tart which was great. It mixed wonderfully in my mixer cup, no grit left at the bottom! I usually drink my preworkout on the way to the gym so it kicks in when I get there but this time it kicked in much faster. I love the new burst of energy! It kept me consistent throughout my workout and had me pumping out some impressive reps. Thank you so much, I will definitely purchase more of this new formula.

Sampling C4 G4 review by Kwhite

I've tried many preworkouts, in an attempt to find a favorite based on both effects and price. I can honestly say the old C4 has been my goto, because there are usually amazing deals. That being said, I was excited when Cellucor allowed me to sample their new G4 C4. In my opinion, C4 is a standard preworkout. It contains the necessities at a fair dosage. 1.6g of beta alanine, and 150 mg of caffeine. It's not going to make you feel cracked out of your mind at the standard dosage and is already effective. When I take it, I always take 1-2 scoops and anywhere in-between. I've experimented it on an empty stomach and an hour after eating, both work just fine, about 20 minutes before working out. The powder mixed almost immediately. There weren't any gritty remains. I enjoyed the previous generations pink lemonade and I can say G4 didn't disappoint. In fact, I'd even say it was better, because it's not as sweet, if I remember correctly. With the minor changes from the old C4 to the new G4 C4, I thought I was going to be experiencing the same thing just with a different design on the container. I was wrong. Although most of the ingredients are the same, I felt a prolonged duration in energy. Looking into it further, I saw that there was a new ingredient. I don't know much about TeaCor Tetramethyluric Acid, but this might be why, considering the other increases in ingredients were minor. I'm usually in the gym for an hour to an hour and thirty minutes and so is the C4 effects. I felt a heightened level of energy throughout the entire duration. The new G4 C4 is impressive.

Good Preworkout review by ET3

Watermelon flavor tastes exactly like watermelon jolly ranchers. The energy is decent. One scoop probably isn't enough for people who have decreased sensitivity to pre-workouts or stimulants. All in all this is by far the best tasting pre-workout powder I've ever tried and I'd recommend it to people looking for a boost of energy, especially if you've never tried pre-workouts before.

ANOTHER GREAT PRODUCT! review by 1LT Nick Brownlee

I just finished my first tub of the New C4 Formula and I was thoroughly impressed with the new formula. I had the Icy Blue Razz flavor and it tastes just like the blue Popsicle we all grew up eating and loving. My energy level were great throughout my workout or anytime I needed a pick me up at the office. Pumps were great and I actually looked forward to drinking it each day. Below are my ratings 1 to 10 on the areas most might find helpful. Taste: 10/10 Mix-ability: 9/10 Energy: 9/10 Cost: 10/10 (for the Price its one of the best preworkouts out there) Pumps 8/10 Overall I loved the new formula.

Awesome Pre Workout review by Joe Sin

This is review on the New formula of C4 (Generation 4). I had never had the opportunity to try C4 before and when I received the 30 servings I could not wait to give it a try. The first day I took it I found that it mixed easily with just a few shakes of the shaker. It was not clumpy and the entire product was dissolved. When I took my first sip I found the flavor to be good. (I had the fruit punch) There was no medicine after taste as is found with other pre-workouts. When I arrived at the gym I felt ready to go. The focus and energy it provided was fantastic without the kitters. The pump was incredible and C4 did not give me any intestinal issues as other pre-workouts have. I have used it everyday for the past 20 days and I still get the same results as I did on day one.

Awesomeness as expected!!! review by ChengJiu

Mixability 10/10- the new formula mixed a lot better compared to the previous C4. The power itself was a lot more refine. Taste 10/10- the blue razz was amazing. Compared to the older generation this one tasted a bit more balanced. The older blue razz seemed a bit too hard on the sweetness but it did its job. The new formula has a balance that is not too sweet or tart. Energy 10/10- I felt the energy really well. I was well motivated to start with but this gave me the extra boost I needed during the later sets and reps. Pumps 10/10- as expected of C4 I had good pumps throughout my workouts. Effectiveness 10/10- when I do take it I typically take it on an empty stomach. It hits me a lot faster compared to the older formula. This could possibly be because the power is a lot more refined and that the body absorbs it better.

I received pink lemonade as the flavor first I would like to tell you about the pump and the vascularity are great my pump and vascularity last about 4 hours after the gym.energy is spot on it's enough to plow through any grueling workout and there is no crash afterwards I actually feel really energized for about 6 hours after I take the product. The mixability was great too no leftover chunks at the bottom or any really hard dying left in the cup I would have to say this product is in my top 5 pre workouts that I've had and tried all in all this will be a staple in my workout regimen thank you again Cory for the free product from cellucor and the opportunity to review it.

C4 watermelon review by garcia77

Cellucor always have quality in their products. The first time taking this product, I used a half scoop to try it out. It mixed with water extremely well and it tasted like watermelon of course, but also leaving a cotton candy-ish aftertaste (which I enjoy). I drank it before leaving the house and was on my way to the gym which is about 10 minutes from my house. About halfway there, I already felt the energy kicking in and was gracefully singing along loudly to one of Pink Floyd's songs. I was so anxious to lift and although I'm not the type to want tingles, they were minor and not distracting as with other PWs. Ended up hitting a bench PR and did not crash at all. Currently at just 1 scoop per workout and I'm satisfied with this product.

Cellucor does it again!!! review by DJ

I finally tried the new C4 from the G4 line, and I must say, I was not surprised at the quality at all, since Cellucor has yet to fail to amaze me! The Fruit Punch flavor was on point, as I consumed two scoops in 12oz water and ice!! The pumps, as usual, were INSANE, and the new form of caffeine used was quite a nice addition to the C4 product as energy seemed to be more clean and constant throughout my greuling two hour workouts! I used the entire bottle in a little less than a month and I get the dame mental focus EVERY time, so yes, the new form of caffeine, I would say, is LEGIT!!! As aforementioned, taste was on point, energy was amazing and consistent, and pumps were always there when I consumed the G4 C4 30 minutes prior to my lifts!

Best Preworkout review by Maria

Obsessed with the new C4! if you liked the G3 series you will absolutely LOVE the new G4 series! The new ingredient TeaCor that they use is the bomb. Not only does it hit harder and last longer, its more effective. i have personally notice the intense muscles pumps during my workouts and my energy is at its high. C4 is by far the best pre workout on the market!

New Formula Delivers on Hype review by Andrew

I was given the opportunity to try the new C4 and review the product, and I must say the new formula delivers on giving you what you need when you need it. Retaining all the micro-nutrients from the 3rd generation (Vitamins C and B's, Calcium, Creatine, etc.) in addition to 100mg more Beta Alanine per serving. Cellucor also scrapped the old energy blend for a new, more concise one. At this time, I've taken C4 for 2 weeks and I can say with confidence that I have not felt any adverse long-term or short-term effects. C4 gives a clean, noticeable increase in focus and endurance that many other "pre's" fall short on in delivering. I would highly recommend C4 for anyone looking to get serious about their workouts and maximising their workout potential. Cellucor has not disappointed me before and the new C4 reaffirms my belief in Cellucor providing nothing but the best.

I received a free sample tub of this product in the mail about a week ago and I've used it 3 times since then. I have to be carful about which preworkouts I use because I tend to be sensitive and I get jittery and unable to focus with other brands. The old C4 never gave me any side effects and I'm happy to say the new G4C4 is the same way! To test the product for the first time I used a little less than 1 scoop and mixed it with 8oz of water and ice in a regular blender bottle. There was no sediment or clumps and I felt the effects in about 15 minutes with 1/2 of a protein shake in my stomach. The difference between the old formula and the new formula is significant. I felt so much more energy throughout my entire workout and even after an hour of lifting I felt like I could do more. I have been using a full scoop now and still no side effects except an amazing pump. I have only tried the old C4 in fruit punch and blue razz so I can't compare the old strawberry margarita flavor to the new one. However the taste is a 10/10 for me. I will be purchasing this product when I'm finished with my sample tub!

I really like this product. review by Baileigh

The strawberry margarita flavor is awesome. It doesn't taste like you're drinking pre-workout. Definitely the best one I've tried.

Great update to C4 review by AcHockey11

Prior to the release of C4 Generation 4, I was not a fan of C4. I was lucky enough to receive a sample size of the new formula, and i figured I would just try it to see how it compared to the old formula not expecting a big difference. Boy was I wrong, this new formula though has totally changed my opinion of C4. I took one scoop 10 minutes before hitting the gym. Part way through my first set I began to feel a clean and clear boost in energy with no jitters whatsoever. This energy level lasted throughout my workout and well into my evening, and eventually letting me down without a caffeine crash. The pump wasn't too bad either! Great job Cellucor!!!

Great product it works review by Neci

I started using C4 when i got back from Germany. I was in the military while deployed i was taking Nitrix and No explode. I switched products after returning back to the states. I had a friend who told me to give it try. I stack my C4 with cellucor BCAA, no jitters, I take it 30 min before my work out and i use BCAA during my workout I sip on it through my rest break. During my entire work out I have energy , focus and strength. I would recommend this product to anyone that trains and that is a true gym head.You feel heart pumping, your mentally focused. I do my 30 min of cardio then I lift weights for about 45 min. I go home and do abs workouts. This last all day even after your workouts.

Great tasting and long lasting energy! review by Kate

Just received the new G4 formula for the orange dreamsicle C4 and I am in love! Great pre-workout that gets you amped up before a workout without crashing afterwards. Plus the orange dreamsicle flavor makes the pre-workout easy and enjoyable. I use one scoop in about 8oz of water about 30 minutes before a workout. The powder mixes great and doesn't clump. It gave me crazy energy to push through a nice leg day. Definitely recommend!

Love the new formula! Great energy! review by JCollumFitness

I absolutely love the new formula! It tastes even better (I didn't know that was possible), I have more energy and focus, and all around feel the effects even more. I almost immediately feel the beta alanine kicking in once I drink it. Thanks for yet again another awesome product!

Amazing!! review by Nina

I loved the original C4 but the new Generation 4 C4 takes things to a whole new level. This product not only gives me the energy for intense workouts, but I also feel like I am more focused during my training. There is no crash with this product, just pure energy that lasts the entire duration of my training. The flavors are delicious, I can't pick a favorite!

This product rocks! review by brennapickett

Taste-10/10 Spot on! I could drink this all day to be honest. I have tried "LeCheek Hottie's pink lemonade" and this flavor stomps on that flavor. Couldn't have made it better. Effectiveness-10/10 I have had great workouts everyday from this product. Just the right amount of caffeine to help wake me up at 5am but not enough to over stim me. Mixability-10/10 No problems at all here. I don't have to swirl my cup before each drink. Mixes easily with a spoon. Overall-10/10 I wouldn't change anything about this product. Flavor is great, works great, and mixes great. Solid product !

Mixes well and gives good energy review by Al

I've been taking C4 icy blue razz for a couple weeks now and have been having great workouts. It tastes good, mixes well, is easy to stomach and within ten to twenty minutes of taking it I'm ready to go with plenty of energy.

LOVE!!!! <3 review by Sara

I've tried a variety of preworkouts and this one is AWESOME! The favor is great (Blue Raz or Fruit Punch!), mixes well, lasts the whole workout, but doesn't make me feel weird the rest of the day and best part.. if I take it at night for an afterwork, workout I can still sleep later! Great product! Wish I had an unlimited stock at all times!

Gen Four C4- Fruit Punch review by Danielle

I just finished my first 30 serving container of Fruit ?Punch Generation Four C4. I’ll start out by saying I noticed a significant difference between the Gen 3 Chrome Series! The new ingredient TeaCor makes a noticeable difference in how long the energy lasts. TeaCor works like caffeine, but without the negative side effects. It is meant to come on faster and last longer! I have been a C4 user for over two years now and I have yet to find a better preworkout out there! I usually take my C4 on my drive to the gym in the afternoon (about a 25 minute drive) and start to feel the effects by the time I pull into the parking lot. The bet alanine gives you a slight tingly feeling, but definitely no jitters or heart racing effect. That is very important to me because I highly dislike feeling jittery during my workouts. My husband and I both tested the Gen 4 C4 together for the first time. Once our workout was over we had the same reaction. The energy was so long lasting! We both agreed that during our workout we felt a constant, longer lasting energy. No crashing afterwards or towards the end of our workout. The taste was delicious as well! I had the fruit punch flavor and its tastes just like Kool-Aid! So yummy! It also mixes very well with no clumps. Some people are concerned with bloating due to the creatine. I have never experienced any issues with feeling bloated or full. Overall, I am beyond impressed with the new Gen 4 C4! I just ordered Orange Dreamicle and cant wait to try it! I also want to thank the Cellucor team for providing me with this product to review!

I hate watermelon review by Itskluv

I tried the original version of c4 in watermelon flavor and I liked it. It was refreshing and a little tangy but I found myself having to chug this one. The only reason I kept using it was because the pump was AMAZING and the energy was clean. I'm a full time nursing student along with a full time job so I need something to wake me up in the morning and this definitely did the trick. I would definitely recommend this new version of c4 just pick a different flavor lol

Good for strength gains but lacks cosmetically review by tennisbgc

This is my review of cellucor c4 Thank you cellucor for providing me with a sample to test. Taste/mixability: 10/10 The flavor I was given was strawberry margarita. Love the taste very nautural taste not too strong or too weak. I normally dose it at 1 1/2 scoops. This stuff mixes very easy to the point were one shake is all it needs. Energy/Focus: 9/10 Energy with this stuff can best be discribed as natural steady as if you got a good nights rest. What I like most about the energy is the consistancy, ive taken a bunch of preworkouts before with mixed results from workout to workout but c4 does it for me every time. it takes about 15 min to feel the effects with very little to no jitteryness. The focus with this stuff is great I feel myself consitrating not only how much I'm lifting but how i'm lifting the weight almost a slowmo effect. Strength/Endurance: 8/10 My strength has definitly improved since taking this. Vascularity/Pump: 5/10 To be honest I was a little disappointed here. At 1 1/2 scoops I simply get very little pump and vein poping. I got a better pump vascularity from 1 level scoop of the old c4 possibly I respond better to fat burning ingredients same with super hd. Side Effects: 7/10 It seems that when I take 1 1/2 scoops My throat gets a little dry and reddness in my face. At one scoop I dont get this but it really doesnt do it for me. Thought: I love the energy I get from this I'm definity lifting more weight than I was with the old c4 but miss the pump definition I got from the old c4 maybe c4 ripped will the answer.

Can't be topped! review by KTunny

I have used many different brands/types of preworkouts over the years, and I cannot and will not steer away from C4. I recently got the opportunity to try Cellucor's newest version of C4, the 4th Generation, and I believe I have fallen in love all over again. I tried the Orange Dreamsicle flavor, which I had never had before, so I was pretty pumped to try it. So, I always take C4 on my drive to the gym which is about a 15-20 minute drive. I always use 1 scoop C4 and mix with about 8oz of water in a water bottle using a funnel. That's right, a water bottle. It mixes completely in seconds without a shaker cup. No grits and the true-to flavor means I am one happy girl. Any other preworkout I had tried before C4, I was having to choke down because of the flavor, grits, or both. Orange Dreamsicle C4 is delicious. The second I walk into the gym I can feel the pump C4 gives me and I don't want to do anything but workout. On the first day I tried the new formula of C4, I was getting reps in that I wasn't able to get in before, I was lifting heavier, and lasting longer. I finished the workout I had written down for myself, and was trying to find MORE exercises to do because I still had the energy. This must have been from the new ingredient in this C4, TeaCor, that gives you faster on-set and longer lasting energy. The focus I get when I take C4 is a big deal to me as well. Usually, I dilly dally on my phone in between sets when I don't take my C4, but I don't have time for that when I do take it. It's awesome and gets better and better every time. I am, without a doubt, a Cellucor fan for life!
