It works!
I have tried other big name brands supplements in the past. They don't work. This product especially cellucor C4 definitely works! I gained tremendous strength and endurance.

I got C4 per-workout along with samples of C4 ripped pre-workout and 2 different flavor of whey protein (cor-fetti cake batter and red violet) The red violet is ok, the cor-fetti cake batter doesn't mix very well. C4 ripped pre-workout flavor was so bad i felt i drink a vodka shot with sour flavor and it burns my throat for a while. The effect is better than other pre-workouts i have taken.

Ordered the molten chocolate whey and decided to try c4 in berry blast. Love both products and appreciated the free samples ( red velvet and corfetti whey), which were also delicious.

Would order from here again. It was nice to get free samples of protein especially when you don't know if you will like it or not.
