The extreme among us 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 made for your extreme passion, drive and commitment to your workouts.


For years you’ve relied on C4 to help you raise the bar and push limits. C4 50X is the next step for those who want to level up. Its formula features approximately 50% more of the active ingredients per scoop that were key to the power of the original C4 Extreme®. C4 50X also has two new ingredients: TeaCor  for hard hitting energy; and XCELICOR™ to help the energy  last longer.*

Contains CarnoSyn ® Beta Alanine

CarnoSyn® Beta Alanine is an amino acid, which converts to a compound in your body called carnosine. It is the only patented and clinically studied form of beta-alanine that has been shown to support muscular endurance.


C4 50X  is available in our classic Fruit Punch, Watermelon and Icy Blue Razz flavors.


How should I take the C4 50X?

Take one serving, mixed with 4-6 oz of water, 20 - 30 minutes prior to training.

How many servings of 50x can I take in a day?

Given the fact that the C4 50x features 50% more active ingredients per scoop, many people have had success with one 1 serving per workout. Once you have assessed your tolerance with one serving, you may take an additional serving prior to training.

I am currently taking a PDE-5 medication for ED, why is there a warning on the label not to take this?

Because of the nitrates ability to relax the walls of the blood vessels to promote increased blood flow, nitrates are frequently included in men’s sexual health products. Taking nitrate ingredients and PDE-5 inhibitors at a similar time could cause an unsafe drop in blood pressure. Because some dietary ingredients also act as PDE inhibitors, please consult a licensed qualified health care professional before taking this product with any dietary supplement, product, or medication.

How much caffeine is in on serving of the C4 50x?

The C4 50x contains 200mg of caffeine per serving.

What is there 50% more of in the 50x?

The ingredients: Beta Alanine, Creatine Nitrate, Arginine Nitrate, and the Explosive Energy Blend are all formulated with 50% in the 50x over the flagship C4.

So you’re saying the C4 50x is just a scoop and half of the flagship C4?

No. In addition to having 50% more stimulatory ingredients, the C4 50x is formulated with the ingredient XCELICOR. XCELICOR is an innovative patent protected caffeine ingredient which combines caffeine and pterostilbene to slow the absorption and significantly extend the half-life of caffeine by up to 25%.

Why does my skin have an itchy/tingling feeling after taking the C4 50x?

The C4 family of products are formulated with the amino acid Beta Alanine, which supports muscular endurance, and often has a tingling/itching effect experienced by users about 10-20 minutes after consuming the product.

Can I stack other Cellucor products with C4 50x?

You certainly can, however you want to make sure to not take in an excess of nitrate ingredients, nor stack stimulant based products such as preworkout and weightloss products. One stimulant based product to be used at a time (C4 Family of products, SuperHD, D4 Thermal Shock) Product with higher concentration of nitrate based ingredients such as the C4 family, NO3, and CN3 are recommended to not be used together.
