C4 50X Review

C4 50X Review and Results:


There are many different pre-workout supplements on the market, but C4 50X is a bit different as it’s marketed as the “extreme” powder for those who don’t know the meaning of the word “quit.” At New Testosterone, we strive to provide you with the best reviews possible, looking past the marketing tactics and studying the results. For our analysis of C4 50X, we looked at the ingredient list to see if there were any scientific studies to back up the company’s claims, and we searched through countless user reviews to see how it affects real people. Here is what we found.

What is C4 50X?

The company that makes this product, Cellucor, is well-known for making workout supplements designed to help your body both increase in mass and recover more quickly. In fact, this is the latest in a line of C4 supplements. What makes this one different is that it’s marketed to extreme fitness buffs who want something that can help them push harder and longer during workouts. The product uses Beta Alanine, Creatine Nitrate, Arginine AKG, Caffeine Anhydrous, and Tetramethylruci Acid (TeaCor).

You can find C4 50X through most third-party resellers like Amazon or Bodybuilding.com, or you can purchase it directly through Cellucor’s website https://cellucor.com/products/c4-50x?variant=28146084114


So far, it seems like using C4 50X does help give you some energy to perform your workouts, but we haven’t found a lot of evidence to suggest that it’s a worthwhile muscle builder. When using it, we do experience some crashes, which means that the energy is not sustainable, so proceed at your own risk. As for the flavor, many people think that it tastes great, but it depends on the version you get. We like the fruit punch and watermelon, but the icy blue razz seems to have mixed reviews.

To help you get the best idea of how our supplements work, we make sure to provide you with customer reviews. These are the people using the product on a regular basis, so don’t just take our word for it.

“If you are struggling to get the motivation to go to the gym due to lack of energy or motivation then you should invest in c4 50x! I have tried numerous different pre-workout supplements, and I would rate this one up there as one of the most effective.” John, Amazon.com

“Two scoops just isn’t enough for me, and apparently I’m not supposed to take more than two daily. And this is coming from not using everyday and more like once or maybe even twice a week. It’s was effective in the beginning but died down for me way too soon.” Brenda, Amazon.com

“Hands down, this is one of the worst products I’ve ever tried. The taste is god awful and its effectiveness…well lets say there isn’t any.” Zack, Bodybuilding.com


When looking at the ingredient list for C4 50X, some red flags give us pause. The only element that seems like it can do the most good for your body is Beta-Alanine https://examine.com/supplements/beta-alanine/ because it can help with muscle repairs. However, everything else has some dubious claims and very little research to back it up. For the most part, arginine is unproven as a supplement https://examine.com/supplements/arginine/, and the Teacor acts more like a stimulant than anything. While it’s true that this mixture can give you an energy boost, it doesn’t have a lot going for it as far as muscle-building or recovery.

Side Effects

For the most part, there are no significant side effects to taking this product, other than users reporting an energy crash after a few hours. Given the level of stimulants in this supplement, we can understand why Cellucor tells you not to take more than two scoops in a day, so be aware that you are getting a lot of caffeine and energy.

Another thing that we’ve seen regarding effects of C4 50X is that some users report sleeplessness and rapid heartbeat. Again, given the amount of stimulation you can get from this product it makes sense. To see how it will affect you, you might want to try half a scoop to see if you get jittery or energetic. If you have a high tolerance for caffeine, then you might only feel a slight buzz.


As far as muscle builders go, it seems like the only things that C4 50X have going for it are the tasty flavors and the fact that you get a boost of energy. However, you can get the same effect by drinking coffee or other sources of caffeine, so you can probably save money that way. As far as muscle boosting goes, the ingredient list is somewhat dubious and there’s not enough evidence to support the claim that you can push yourself that much harder than normal. Most likely it’s the added energy that makes users think that they are capable of working out more.
