The results of my research into C4 Fat Burner were somewhat surprising. We decided to create one of our in-depth reviews, examining the side effects, ingredients, clinical studies and overall customer service. We also looked at hundreds of customer responses and user comments posted all over the web. Lastly, we summarized and compacted everything we found to give you the bottom line.

EDITOR'S TIP: Substitute C4 Fat Burner with a proven fat burner such as Leptigen for better results.

What You Need To Know

Firstly, C4 Fat Burner is manufactured by Powerlab Nutrition, and it’s claimed to be the “most advanced fat burner ever.” Moreover, this supplement is said to contain the “strongest combination of fat-burning ingredients, ever.” The ingredients used in C4 Fat Burner include the following: Caffeine (200mg), Coleus Forskohlii (200mg), L-Tyrosine (100mg), Evodiamine (50mg), Niacin (25mg), Synephrine (25mg), Guggul Lipid Extract (20mg), Yohimbe Bark Extract (10mg), Vinpocetine (10mg) and Absorbtech (10 milligrams of Bioperine and Vanadyl Sulfate). You simply take one capsule before breakfast and one capsule in the early afternoon (or 30 minutes before workout). After three days, you can double the dosage. C4 Fat Burner is intended to boost metabolism and heighten energy levels.

We are not sure when C4 Fat Burner was initially released, but it is available through some online dealers for around $30 per bottle (no longer on the official website). Furthermore, this supplement is fine for women and men alike, and it does contain some natural ingredients, but read on…

Dangerous Ingredients – Is it Safe?

According to our Research Editor, “C4 Fat Burner contains a combination of Synephrine and Caffeine, which is unsafe, according to WebMD. When these two ingredients are combined, it can lead to high blood pressure, fainting, heart attack and/or stroke.”

One customer said, “Causes nausea, anxiety, headache, tremors, you name it. Bad stuff.”

“Made me very jittery and my heart would pound like crazy,” complained another user.

Discouraging User Reviews!

We noticed some off-putting customer reviews posted on the web for C4 Fat Burner. One person commented, “Does not help with weight loss. Definitely gives me a buzz, but no weight loss!”

“This fat burner causes some serious side effects! Not cool! My doctor told me to stop taking it,” stated another individual.

Our intense research has proven that if there is some individual part of a weight loss pill or diet program that is especially problematic or concerning (dangerous ingredients, discouraging user reviews, low Amazon rating) the real chances of weight loss for the long term are not good. This means if C4 Fat Burner results in a lot of negative user reviews, this could be a serious issue.

The Science – Solid?

At DietSpotlight, we prefer to see some solid clinical research that supports the diet product and its weight loss claims. Sadly we did not find any real clinical studies or science that supports C4 Fat Burner. While this formula does contain caffeine to boost energy levels, there is no evidence that shows this supplement is a powerful fat burner, as claimed.

The Bottom Line: Does C4 Fat Burner Work?

So, should you buy C4 Fat Burner? First of all, we do appreciate that C4 Fat Burner contains some natural ingredients and it is easy to purchase online. However, we have some doubts about this diet pill because it’s really not backed by any clinical studies. Moreover, we’re concerned about the dangerous ingredient combination used in C4 Fat Burner, as well as the discouraging customer comments posted online.

If you’d like to get rid of some serious pounds, then we encourage you to choose a product that contains only safe ingredients, is backed by solid science and is supported by plenty of positive customer reviews and comments.

Among the best products we’ve seen in 2016 is one called Leptigen. Its formula is a potent blend of four key ingredients, which have been shown in documented clinical research to help elevate metabolism and increase fat loss. We can’t find any comments about unpleasant side effects and the user feedback posted on the web reveals people are seeing solid results.

The makers of Leptigen are so satisfied with their product they’re offering a Special Trial Offer, which is a good sign.

What You Should Know

C-4 Fat Burner from Powerlab Nutrition claims that it is the "most advanced fat burner ever developed." The manufacturer claims this supplement contains the strongest combination and dosage of fat burning ingredients ever.  C-4 Fat Burner promises to dramatically increase the user's energy for supercharged workouts, as well as raising the body temperature for increased metabolism even after workouts.

Ingredients

Synephrine, Yohimbe Bark Extract, Caffeine, Guggul Lipid Extract, Bioperine, L-Tyrosine, Coleus Forskohlii, Vinpocetine, Evodiamine, Niacin, Magnesium Stearate and Gelatin.

Product Features

Powerlab Nutrition, the company behind C-4 Fat Burner, is a well-known name in the sports nutrition industry. The C-4 Fat Burner capsules seem to be geared towards serious athletes trying to eliminate nearly all body fat.  Based on this claim, this supplement is likely not the right choice for anyone looking to shed a few pounds or jumpstart a weight loss program. Having virtually no body fat is not only an unrealistic goal but one that is not particularly safe. In fact, safety does not seem to be the highest priority with the C-4 Fat Burner. One of its ingredients is synephrine, a product which is very similar to ephedra and has been singled out for some of the same reasons as that now banned product. There are also warnings against using synephrine with caffeine, something that Powerlab overlooked with this product. If these two facts are not enough to discourage the potential user, it should be pointed out that components like yohimbe bark can cause nausea, headaches and dizziness and evodiamine is a diuretic.  C-4 Fat Burner is available at a number of vitamin and bodybuilding supplement sites online. The list price is $59.99 for 120 capsules, but some sites sell for as low as $34.99, so it is best to look around if you are still determined to try this product.

Advantages

  • C-4 Fat Burner works on the principles of thermogenics.

Disadvantages

  • C-4 Fat Burner includes a number of unsafe or untested ingredients.
  • Customer reviews for C-4 Fat Burner vary. Most reviewers say it works but give a list of side effects such as becoming too wired or too jittery.
  • There are no guarantees available for C-4 Fat Burner on any of the sites were it is available.

Conclusion

Powerlab's claim that C-4 can eliminate all body fat are unrealistic and not medically wise. Some of the ingredients found in C-4 raise a number of safety concerns.  There are many products on the market that aim to help the consumer lose weight. The wise and informed consumer should make every effort to find one that will first do no harm. Look especially for products that contain a fat burner and an appetite suppressant with their metabolism booster. Avoid those that have things like diuretics which give the false impression of results. It is also smart to rely on research and customer reviews to verify the claims of the manufacturer. There are products out there that work, use care to find the one that works safely for you.

    Honestly, you feel your body get warm and the caffeine is powerful. Definitely need to keep hydrated with this. I had lost 20 pounds in about 8 weeks while using this product, but those results are most likely due to my diet change rather than this product. It is pricey, but you definitely feel this thing working on your body. I would recommend this to someone who wants to try something different. With this in mind, I still feel like fat burner isn’t something needed to lose weight. Take pre-workout instead before a workout and then have the proper diet and there ya go.
