C4 50X

MADE FOR THE ELITE

The most extreme competitors believe in all or nothing, go big or go home. For extreme competitors, 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 the competitor's extreme passion, drive and commitment to succeed.

C4 50X™: 50% MORE EXPLOSIVE

For years you’ve relied on C4 Extreme® to help you raise the bar and push limits. C4 50X™ is the next step for you, the most extreme competitor. Its formula 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: the patent- pending TeaCor™, an integral part of C4®, and patented XCELICOR™, the latest innovation in energy--the X-factor ingredient in C4 50X™.*

A 360° VIEW OF C4 50X:

  • 50% more explosive formula
  • Features TeaCor™
  • XCELICOR™ for energy
  • Available in the classic C4 flavors
  • Made for the extreme

BURSTING WITH FLAVOR

C4 50X™ is available in our classic Fruit Punch, Watermelon and Icy Blue Razz flavors. Even though you’ll slam it back, you’ll want to savor every sip.

This product tasted good, didn't notice much difference between this product (50X) & regular C4. It gave me a little boost before workouts. Overall, I'm happy with this product. Of course I got it for free though.*
