Great pre workout! Don't use to much the first time. You need to build your tolerance to it. I took to much the first time & was all tingly and itchy.... After that I learned my lesson and I have been using it since. The flavors are wonderful as well!

C4 is probably one of the better pre-workouts I've tried. The other flavors are really good and you can get it for a reasonable price. It gives you a great muscle pump and tons of energy to get through your workout! It does make you retain water weight so not ideal if you are trying to lean out.

Use with caution. Follow the instructions carefully. This is a thermogenic product, so you will sweat quite a bit more. The creatine will also aid in building muscle. If you take it before a tough workout, you will be able to push yourself harder and see good results. Just make sure to cycle off.

This is the ONLY pre-work out I use. I've tried to many, but they all make me feel out of control with too much energy, but the Cellucor C4 Extreme, is just right! The taste is also SO DELICIOUS! I never skip this delicious treat before going to the gym!

I use this before my insanity workouts and it helps keep me going. the only thing i don't like about it is the prickly feeling i seem to get on my ears after taking it (but it happens a few minutes after taking it so it lets me know its kicked in)

I love this stuff! I always drink it an hour before my workout and it helps me focus and concentrate on my workout for that day. I usually always buy blueberry, its tastes great!

Got a free sample from gnc with 4 servings. the watermelon flavor was amazing. did not like how it made me feel at the gym though. my face and arms became very itchy and long after taking my face was burning hot. didn't experience and crash or jitters, but wouldn't purchase for the price.

I have tried a lot of preworkouts and c4 is my favorite no matter what flavor but id recommend strawberry margarita. Gives energy and tingles and makes for a much more intense workout session. Be sure to read the instructions and always cycle.
