For me, C4 just didn't get me in the "zone" like products I have taken in the past. IMHO I believe this product is a good beginer pre-workout supplement due to its lack of significant pumps as well as its reluctance to provide extreme energy increases prior to a workout (I took it at 5 am). I probably will not buy this product again and will shop around for a different pre-workout supplement. (Posted on Jan/25/2013)

This is the best pre workout I have used and I try to stick to it whenever possible. I have tried all flavours and none disappoint but Pink Lemonade is my favorite. This is the smoothest, best quality pre out there in my opinion. No crash or anything. Get this stuff if you havent already.

First off, I wanted to say, wow! This is my favorite pre workout of all time. I have taken many pre workouts and this is by far the best in my opinion. I will rate this product on things that I got from it. Pump, strength, endurance, focus, and taste.

Dosing was 2 scoops with about 8 to 10 oz of water about 15 minutes before heading to the gym.

Pump 8/10:

I always get great pumps from c4. I love seeing my veins popping out all over my arms, makes me feel like a bad a**, haha. I even get good pumps on chest and back day, which for me has never happend before with any other pw.

Strength 8/10:

I feel a lot stronger when I take C4. I seriously feel stronger as soon as I drink it, makes me just want to get in the gym and go hard,

Energy/Endurance 9/10:

I tied these two together because with the energy that I get from C4 it helps me keep going, and going in the gym. I never want to leave because I feel so energized. I usually wait about 2-3 minutes between sets, with c4 I can go with 45 seconds to a minute and I will be set to hit my next set with full power.

Focus 7.5/10:

Focus isn't too bad. I still get distracted at times while in the gym, but maybe its just me. I have had more focus on other products like craze for example so I know that the focus could be better, but its not bad. I still get great workouts.

Taste 10/10:

Cellucor really knows how to make their products taste great. I have tried many flavors of C4. Pineapple, watermelon, fruit punch, and blue razz(my favorite). You will not be disappointed with any flavor that you choose.

Overall ratting 9/10:

I love this pre workout and I will for sure always keep in my stack. I highly recommend this to anyone looking for a solid pw that works, and taste great as well. ;) (Posted on Jan/21/2013)

Taste: 8.5/10

The Blue Raspberry flavor is very delightful to drink. It is not very strong or overly sweet. I have found that using less water is the key if you like it to be abit stronger tasting otherwise it will just be a nice subtle blue raspberry flavor. I have tried some other Blue Raspberry flavors and this one unfortunately isn't the best but is still a very solid option!

Product Profile/Ingredients: 8.5/10

I really like the product profile of C-4. First off it is low calorie/carb which is great for those dieting. It also has no fillers such as Maltodextrin or other carbs. Another thing I like about the profile is that it shows how much Caffeine your getting at 135mg. This is a greatstarting base for most people and will not overstimulate you.

I would give a higher rating if the product still contained 1 3 Dimeth and didn't hide some of the ingredients in a proprietary blend. I understand why companies do it but for myself I always like to know how much I'm getting of each ingredient. The good part however is that alot of the main ingredients like the Creatine & Beta Alanine are listed which makes it easy to supplement more throughout the day to meet daily requirements.


Pumps: 8.5/10

I have been cutting for many months now and have been making some good progress of late. Usually because I am eating very little in the way of carbs my pumps have sort of been non existent at times. However I have certainly noticed an increase in this area while taking C-4. It has been most noticeable when training areas such as the Biceps/Triceps.

Energy: 8.5/10

C-4 has been delivering a consistent boost to my workouts. I have found that the perfect dose for me is 1.5 scoops. This delivers the right amount of energy without overstimulating me and leading to a crash after my workout. This product will certainly help you push through those grueling days when you don't feel like being at the gym.

Focus: 7.5/10

Since the removal of 1 3 Dimeth from previous C-4 version I have found that some of the mental focus is missing from this product. While I still do notice more mental focus it is just not in the same league anymore like it was before.


Endurance: 7.5/10

This is perhaps the weakest link of C-4. I find it does certainly give you a solid boost to begin your workout but sometimes towards the end I feel that it wears off abit.

Side-Effects: 10/10

I have not had any issues while taking this product.


Overall Rating: 8.5/10


C-4 is a very good all around pre-workout which I highly recommend. If your looking for a product to give you an edge in the gym certainly give C-4 a try and I'm sure you won't be disappointed. You will find that your workouts will be more intense and you'll certainly be feeling more pumped up and determined to crunch out that extra rep which you couldn't before! (Posted on Apr/27/2012)
