We’re going to be paying particularly close attention to the ingredients formula, the customer reviews and the dosages as we look to see whether this product lives up to the hype or not.

So, with the introductions out of the way, let’s start taking a closer look at Cellucor C4 Sport to see where it stands.

Cellucor C4 Sport Pre Workout – The Basics

As we have already mentioned, Cellucor C4 Sport is a pre workout supplement that’s available on Amazon in the US as well as through some other retailers.

Cellucor C4 Sport is also available in other countries such as the UK, where it has a slightly different ingredients formula to the US version, but there are also lots of similarities between the two versions.

In the UK, the Cellucor C4 Sport pre workout is also available to buy in some shops such as Holland and Barrett.

Cellucor are one of the biggest names in the supplements industry, and they have a pretty good reputation.

You can buy Cellucor C4 Sport on Amazon, where it costs around $20 for a 30 serving tub.

It’s currently available in a number of different flavors, including:

• Blue Raspberry
• Fruit Punch
• Watermelon

The marketing material on the official Cellucor website says that C4 Sport has been specifically designed to help support your goals to get you through the “toughest moments” of your fitness journey.

The description continues by saying that C4 Sport has been specifically designed to be taken before periods of exercise.

The directions simply say that you should take one scoop of the powder mixed with water around 20 to 30 minutes before starting your training or exercise session.

So, this all sounds pretty good to us so far, but we’ve learnt not to pay too much attention to what manufacturers say about their own products.

Instead, it’s better to focus on the important things such as the ingredients formula and the customer reviews.

With that in mind, let’s move on to the next important part of the Cellucor C4 Pre Workout review.

The Ingredients

Let’s begin this part by taking a close look at the actual ingredients label of the Cellucor C4 Pre Workout, as shown on the tub.

Note that these ingredients are for the US version of this product. If you’re buying it in another country, there may be some slight differences.

It’s worth noting that Cellucor uses something called a ‘proprietary blend’ for certain parts of the C4 Sport formula. This means that some of the ingredients’ doses are not disclosed, and instead only the total amount of the ‘blend’ is shown. The UK version of Cellucor C4 Sport does not use a proprietary blend.

Editor's note: The health claims about the ingredients mentioned in this article are listed as authorised on the EU Register at the time of publishing.

Let’s now focus on some of the main ingredients in the Cellucor C4 Sport formula.

• Vitamins B6 and B12 – These are two important vitamins that we need to get from our diet. Vitamins B6 and B12 contribute to normal energy and the reduction of tiredness and fatigue.

• Calcium – This is an essential mineral that’s present in some foods. It’s a decent inclusion in the Cellucor C4 Sport ingredients formula, because Calcium contributes to normal energy release and normal muscle function.

• Creatine Monohydrate – Probably one of the most common pre workout ingredients. Creatine is a good inclusion in the formula, for reasons you’re probably already familiar with.

• Beta-Alanine – This is another pretty common pre workout ingredient. You’ll find it in most of the top pre workout supplements on the market these days, so it wasn’t a surprise to find it in the C4 Sport formula.

• Caffeine Anhydrous (135mg per one-scoop serving) – You probably need no introduction to Caffeine as an ingredient. It’s one of the most popular stimulants on the planet. Each serving of C4 Sport contains 135mg of Caffeine. To put that amount into perspective, you’d usually expect to find around 100mg of Caffeine in a regular cup of coffee.

• Taurine – This is a common ingredient in many commercially-available energy drinks, so you can probably see why it’s been included in the ingredients formula here.

The Cellucor C4 Sport pre workout formula has some pretty good things in it, even if it is a little bit disappointing that it uses a proprietary blend for some of the ingredients (in the US version).

Remember that it’s important to check the label of any product you purchase, as the ingredients and their doses can change from time to time.

The Taste

We tried out the Fruit Punch flavor of Cellucor C4 Sport.

When we first opened the tub, we found that the powder had hardened in certain places, but we were able to break most of it apart again using a spoon.

We were very impressed by the way Cellucor C4 Sport mixed into water. It essentially dissolved immediately to form a pink colored liquid, and did not require much mixing.

In terms of the taste, the fruity flavor was very sweet and pleasant to consume.

It did have a little bit of a ‘synthetic’ aftertaste, but we’ve found that to also be the case with most of the pre workouts we’ve sampled.

Cellucor C4 Sport Pre Workout Reviews

We took a look on Amazon to see what real customers were saying about Cellucor C4 Sport.

One of the positive reviews came from somebody who left a five-star rating and said that C4 Sport was the best-tasting supplement they had ever tried.

One of the more negative reviews came from somebody who left a two-star rating and said that they felt the supplement was only “OK”.

What About Side Effects?

You should always carefully check the ingredients label before thinking about taking any new supplement to make sure that you’re not allergic to anything in the formula.

The main thing to be wary of when it comes to pre workout side effects is the overuse of stimulants such as Caffeine.

The 135mg dose of Caffeine in Cellucor C4 Sport is a little bit more than what you’d expect to find in a regular cup of coffee.

The UK version’s label says that you should not consume Caffeine from other sources while taking this product and that you should discontinue use two weeks prior to any surgery.

There’s a warning on the UK-version of this supplement saying that it’s only intended to be consumed by healthy adults aged 18 or over.

The UK label also says that you should not use this supplement before first consulting your doctor, especially if you’re taking any prescription medication or over-the-counter medication, or if you suspect you have or have been treated for, diagnosed with or have a family history of, any medical condition.

Cellucor C4 Sport should not be used by children, or pregnant or breastfeeding women.

We always strongly recommend that you speak to your doctor before thinking about taking any new supplement for the first time, or making any major lifestyle changes.

Anything Else To Consider?

Just remember that a supplement cannot solve all of your workout problems for you.

It’s always best to make sure that you’re sticking to a good diet and training regularly before thinking about taking any new supplement for the first time.

A good pre workout can help to support you as you look to hit your goals, but it will still have to be your good self lifting the weights, and staying disciplined in both the gym and the kitchen.

That said, a good pre workout supplement can be an excellent addition to your regimen if you’re already making sensible choices.

Review Conclusion – Final Thoughts

That brings us to the end of our Cellucor C4 Sport review.

Overall, we think that this is a decent pre workout supplement that has a lot of good things in it.

The US version of this product is let down a little bit by the fact that it uses a proprietary blend for some of the ingredients.

All in all though, Cellucor C4 Sport is a pretty good pre workout option in our opinion.
