Raptorbh12's C4 Extreme Review

Overall: 9 | Effectiveness: 9 | Value: 9

I was pretty impressed when I tried this pre-workout product.
It is a brand new pre-workout product developed by Cellucor which is known for its outlandishly overpriced supplements but this certain one strays from the pack and is actually affordable!
You can purchase it for as low as $22.99 shipped....

Overall: 7 | Effectiveness: 8 | Value: 6

I normally just stick with SP250 and Jack3d as my PWOs. I’m in a more focused environment for most of the year and wanted to try some new things. C4 has recently been very popular so I gave it a shot.

Energy 8/10

So here is the main reason most of us take a PWO. We want that energy boost...

Cray's C4 Extreme Review

Overall: 8 | Effectiveness: 8 | Value: 8

I’ve always been unimpressed by Cellucor as a supplement company. In my eyes their products are far too overpriced and overhyped, and I simply have a hard time swallowing the whole “you’re paying for results” argument. That being said, I was impressed when GlausenLMT offered to send me a tub...

Consistent Pre, Great Taste SS with Horrible Dyes, and a Hefty Price

Hey guys, this review is long overdue. I would like to thank the ER, MikeCellucor, and another Cellucor rep(forget her name) for hooking me up with plenty of tubs/samples of C4.

Ingredient Profile:

Pros- I like the amount of caffeine in here. 135mg per scoop, 270mg for 2, not too much, and not...

Cellucor's C4 Extreme Pre-Workout. Thanks to Cellucor for participating in the ER Program and allowing a few of us to try their new flavors of C4.

C4 is the middle bear of my pre-workout of choice. Not too stimulant heavy and not too light, but just right. Clean and clear every time, with lasting...

Big thanks to the guys over at Cellucor, they are extremely generous when it comes to getting out products to ER members and for that I am very gracious.
I have gone through several tubs of the newer version of C4 and must say that I like it very much for its consistency and solid results.

I actually...

Overall: 8 | Effectiveness: 9 | Value: 6

I'd first like to thank Cellucor for the generous package they sent for us to test. I was originally sent the Fruit Punch & Ice Blue Raspberry flavors with the whey protein. The second round was their new flavors of C4 which included Green Apple and Strawberry Margarita.

I am probably the biggest...

Quality Ingredients, Amazing Taste, but HEAVY on dyes.

Overall: 7 | Effectiveness: 8 | Value: 6

I will keep this one very short because, lets be honest, this has enough positive reviews and has been out for quite some time so most of us here know what to expect from this.

I have mentioned before, Cellucor does an excellent job with their flashy labels and cool containers. They really get you...

I want to thank Cellucor for being a solid partner to the ER program and allowing us to run all their products. C4 is a solid...

fmrPRO's C4 Extreme Review

Overall: 8 | Effectiveness: 8 | Value: 10

C4 is a good quality pre-workout. Not my favorite, but FAR from the bottom.

First off, thanks Glausen for the free tub of this! With that considered, some of my values are a bit skewed. Not only price, but taste, and some other things, but ill divulge more later. Also, if you want to see my day to...
