Extremists believe in all or nothing, go big or go home. For the extreme, average is not enough. There will always be a boundary to break, a limit to push, a goal to demolish, and more to achieve.

After extensive research we developed C4 50X, a pre-workout supplement that matches extreme passion, drive and commitment to succeed.


C4 50X features approximately 50% more of the active ingredients per scoop that were key to power of the original C4 Extreme. C4 50X also has two new ingredients: TeaCor for energy that hits like the first time, and XCELICOR, for long lasting energy.*

Flavor sucked didn't feel a pump but like the profile I got two samples wouldn't warrant a purchase


Perfect amount of dosage is anywhere from 1 1/2 to 2 scoops. Pretty potent stuff so try 1 scoop first. Fruit Punch tastes terrible. Which in the long run isn't that bad is you don't want to use as much. So the 30 servings goes a long ways. I suggest watermelon flavor.

Hate that it has a proprietary 'Explosion Blend' - I want to know exactly how much of everything I'm putting into my body! Taste pretty good though

I'm definitely a fan of C4 50x. Its higher servings count (45 servings rather than 30) and affordability convinced me to give it a try and I am not disappointed. The watermelon flavor tastes really really good, reminiscent of a jolly rancher. It mixes pretty well, tastes amazing, and gives me steady energy for the duration of my workouts. I would recommend it.
