Cellucor has one of the most friendly and helpful customer service departments that I have dealt with in a long time. This means a lot to me as a customer and has helped them earn my repeat business. The great customer service combined with great supplements that give me the results I'm looking for is a win win for me! Thank you Cellucor and keep up the good work!

I love the Strawberry Milkshake protein! I also liked the added bonus of getting a 4 serving pack of Vanilla at no extra cost!

I tried C4 right before I was going to run a Spartan race. Unfortunately, we got caught in an extremely long line and I was bursting at the seams with energy. The label warns you might feel some "tingling" and that is completely true. Kind of freaked me out before I read that. Ultimately, for someone like me who loves to have a lot of energy, it's great.

I have really enjoyed the product, but when I received my C4 ripped it had moisture in it and all the powder was in one big chunk. I would like to order this stuff again when I run out but I do not want this to happen every time. Other than that I enjoy the product and it works well.
