C4 Pre Workout Reviews from Personal Users

“To begin with, this product seemed somewhat decent, although from my personal experience it wasn’t effective for me whatsoever. Upon first supplementing with C4 I felt the first kick of energy that you usually get with pre-workouts, but that only lasted around 20-30 minutes, after which it made me crash hard towards the second half of my workout. I would have the urge to uncontrollably yawn and would lose around half my focus. This even happened with half a scoop and one and a half scoop servings so I asked my gym partner if he’d tried it before, he said he had and it had the same effect on him too. This may work well for some, but unfortunately for me, it’s a complete dud. It only has more than 1 star because of the taste” -Personal User, Overall Rating 3 out of 10

“Have been taking this for many years now. I still look around for other pre workouts and to try new brands but this one is probably the most reliable. Great initial burst of energy that last throughout most of my workouts. Overall, great product that does not feel like your drinking a bunch of fillers. Flavor is great, I did not care for the berry bomb though. The watermelon taste like the jolly rancher watermelon.” – Personal User, Overall Rating 9 out of 10

“This review is for C4 in general. Not any specific type. I have tried all C4 types (original, 50x, neuro, ripped), except mass and ultimate (just purchased, have yet to try). Cellucor is an outstanding brand. C4 is their best product. I have been taking it for 5 years now, and still love it. I have not had to cycle off of it, and still gain the effects from it. Focus, energy, pumps. What you see is what you get. I have noticed no side effects, and will continue to be loyal to Cellucor. Outstanding product, no matter what type you pick. Recommend any day of the week. There are no bad flavors, but some of my favorites were orange Dreamsicle and pink lemonade.” -Personal User, Overall Rating 10 out of 10 

I have purchased the 4th generation and 3rd generation products and this is my favorite pre-workout I have ever purchased. I have purchased many other pre-workout products over the years (because there are many other products with a better price point) but I always come back to C4 because I feel it is the most effective for me. The caffeine source in the product and other ingredients are well put together to deliver an amazing product.” – Personal User, Overall Rating 9 out of 10

I have found many people that have used C4 for themselves and the results are almost the same, they love it. I love C4 and so do others.

Everyone is slightly different and may find that some products simply do not work for them. If you are interested in C4 I recommend you trying it and leaving a review of your own in the comment section below.

C4 Pre Workout Review From Supplement Reviews.com

I’m new to the site, but far from new to supplementation. C4 was the first pre-workout I was introduced to, so what better way to go about my 1st review? I’m a recreational lifter since that’s all a college schedule will allow.. I run an online ebay store (SwoleSuppsNutrition) which somewhat explains my passion for the supplement industry… Most of all I look to clear up the garbage products and misinformation floating around; directing those willing to listen, to what works.

—-Ingredient Profile—-
C4 Extreme is a beginners dream, simply put.. Arginine AKG & Creatine Nitrate are both a major factor in just about any pump supplement, so why not throw it in a pre right?.. The caffeine and beta alanine are the main compounds involved with an increase in endurance (expect some tingles), but the amino acid L-Tyrosine is all about focus. C4 utilizes a profile where focus isn’t it’s main benefit (but it will indirectly increase focus); nonetheless if you’re new to supplementation, this ingredient profile is more than sufficient.
Ingredient profile 7/10

The taste of C4 has always exceeded my standards; blue razz is simply delicious, but watermelon is basically a jolly rancher… Mix-ability should always be good if not great.. As for dosage, everything is up to par for what they disclose on the label, but you should gauge yourself at first (1/2 scoop, 1, 1 & 1/2, 2; whatever works for you specifically). Overall a stern 9/10

The pump is definitely on par, even now (3years later), I still go back to the pre that got me hooked. Yes, you can stack this with another pump supplement, but you’ve already gotten your “nitrates” so steer clear of those.. As for endurance, C4 is more of a weight oriented endurance; don’t get me wrong cardio still takes on another level of intensity, but you won’t feel the potential of a sustained workout until you hit the weights. FOCUS to me is the most important part of a pre-workout because lets face it, if you can’t focus, each set and each rep seems to drag on… You should enjoy improving yourself rather than anxious to quit. Since focus could be improved (although they made the “C4 4th Gen Neuro” for this purpose) C4 Extreme 3rd Gen gets a 8/10.

C4 3rd Gen is quite cheap per serving as of now (Nov, 2017) and Cellucor is really pushing C4 4th gen, you should get a great deal while nearing 2017; C4 gets a 10/10.

—-Side Effects—-
Because of the fact that everyone’s body is different, few will experience the same effects (good or bad). No unwanted side effects for me, however, it does help to clear the colon at unexpected times… 9/10.

C4 is an fantastic go to for those who are just starting, you may develop a tolerance soon after and need to get a more stim focused pre, but this is a great option no matter how you look at it! In conclusion, C4 3g gets a resounding 8/10!” -Member of Supplement Reviews.com, Overall Rating 8 out of 10 

C4 Pre Workout Review From Diet Spotlight.com

“The results of my research into Cellucor C4 were somewhat interesting. We did an extensive review, examining the side effects, ingredients, clinical support and overall customer service of this company. Furthermore, we took the time to sort through hundreds of comments from user posted online. Lastly, we summarized and condensed all of the facts and feedback to give you with the information you need.

What is Cellucor C4?

First off, Cellucor C4 is pre-workout supplement. The ingredients are beta alanine, creatine nitrate (NO3-T), arginine akg,Explosive Energy Blend: n-acetyl-l-tyrosine, caffeine 150mg, velvet bean (mucuna pruriens) seed extract (l-dopa), TeaCor tetramethyluric acid. You’ll add one scoop to water and drink. After accessing your tolerance level, you can use an additional scoop prior to training. Supposedly, you’ll experience unbelievable muscle pumps, explosive energy and intense focus.

Cellucor C4 was first released in December of 2014 by Cellucor; a brand started in 2002. The official website, online retailers and local stores sell the supplement. We like that it uses a few natural ingredients and the longevity of the business, but read on…

Cellucor C4 Side Effects – “Mild or Worse?”

Our first concern relates to Cellucor C4 ingredients causing side effects. “If you take this before a workout, you will probably get an energy boost,” said our Research Editor. “But, using a product that contains 125mg of caffeine per serving multiple times per day could cause adverse reactions.”

One customer said, “I felt really jittery and sick after taking Cellucor C4.”

“Asked myself if Cellucor C4 caffeine content was actually 125mg, because it made me sick,” said another user.

While some users talked about side effects, we located Cellucor C4 reviews where customers didn’t experience any reactions.

“Good clean energy. Definitely on my must buy list, “reported a customer.

Bad Taste – “From Fruity Flavors?”

According to Cellucor C4 pre workout reviews, it has a less than desirable taste. One customer said, “For one, the taste wasn’t good at all and I didn’t notice a change in my performance at the gym.”

Another user stated, “It tasted a bit artificial. Not for me.”

Based on some reviews of Cellucor C4 ingredients, users enjoyed the refreshing flavors.

“Love the Icy Blue Razz. It’s my go to flavor,” said a customer.

“It’s hard to choose because they’re all good,” reported another.

Our research shows that when there’s a particular part of a supplement that’s problematic, such as not being flavorful, long-term success is minimal. If Cellucor C4 is in fact hard to swallow, this could certainly become an issue.

The Science – “Proven Effective?”

Even though Cellucor C4 is touted as “explosive energy for legendary workouts” on the official website, we were unable to find clinical studies to support these claims. It’s unfortunate, considering there’s solid science supporting the metabolism boosting effects of caffeine. For us at DietSpotlight, it’s imperative that we find documented research connecting a products ingredients and effectiveness.

The Bottom Line – Does Cellucor C4 Work?

So, will Cellucor C4 pre-workout provide explosive energy? Well, we like that it contains a few natural ingredients and that the company is a trusted name in the industry. But, we have concerns about this one because there’s no research supporting the claims. We’re also a bit skeptical due to user reviews talking about side effects and poor taste.

If you’re ready to boost energy levels and transform your life, we suggest going with a supplement containing ingredients backed by science and no reports of harmful side effects. –Summer Banks at Diet Spotlight.com, Overall Rating 5 out of 10

What Is The Conclusion?

So bottom line, everyone has an opinion. I want you to come up with your own. There are many people including myself that swear by C4 and they’re are others who think it is garbage. I would love for you to read my full C4 review and if you get a chance to try it, come back to my site and leave a review of your own.

  1. I received a sample of Cellucor C4 from bodybuilding’s website with an order that I placed, and I tried it out. I liked the taste, but I didn’t feel any different so to speak? Like, I wasn’t overly energized, or any more tired upon completion of my exercise.

    Maybe I need to try it on a continuous basis? You think that I might experience a different feeling in that regard?

    • Hey Christian! Some people just don’t get the full extent of C4 for some reason. I have a theory that I think has to do with people that have a disorder like ADHD or ADD. Ingredients like caffeine do not have the same effects on people with those conditions and can almost put them to sleep. I think people that find C4 does not help them could have one of those disorders and not know it.

      I would suggest trying it a few times with different serving sizes to really find out if it helps you.

      Thanks for the question,
