5 Top Cellucor C4 Pre-Workouts (April 2024)

1 - C4 Original

Rated 5.0/5

C4 original pre-workout supplement CTA container product

Pros and Cons

Pros

  • Explosive energy blend ingredients are reportedly effective for power and endurance
  • Contains added vitamin C and B vitamins for lean muscle mass repair
  • 150mg of caffeine to boost focus and motivation
  • Good selection of flavors to choose from

Cons

  • Slightly low on the creatine side

This is probably one of the most popular and versatile pre-workouts in the Cellucor C4 supplement range.

With a formula that contains creatine that claims to make you experience more strength and better pumps, I have seen this make quite a difference to the average athlete.

Just keep in mind that if you regularly do high-intensity workouts, the amount of creatine in this C4 Original Pre-Workout may not be quite enough.

However, it has vitamin C and B vitamins to help with faster muscle recovery.

2 - C4 Sport

Rated 4.8/5

Cellucor C4 Sport supplement product

Pros and Cons

Pros

  • Contains beta-alanine that has been shown to support endurance
  • Sugar-free option to avoid messing up your diet efforts
  • The small amount of creatine may support physical performance levels
  • Good value for money

Cons

  • It’s only really suitable for less intense workout sessions

The C4 Sport Pre-Workout option is the cheapest in the range. It’s most suitable for less intense workouts like running as it doesn’t contain the more powerful ingredients like creatine and theacrine.

However, you could still get a boost from the beta-alanine, which could help in your average cardio session.

Here you can find other recommended pre-workouts tailored for runners.

If you need maximum energy and performance, this is not going to be your top choice.

3 - C4 Ripped

Price
Cellucor C4 Ripped Pre Workout supplement product

Pros and Cons

Pros

  • Formulated to support cutting and body weight loss
  • Combination of L-carnitine, green coffee bean extract, and cayenne may boost thermogenesis
  • The reported explosive energy boost from beta-alanine to allow you to complete more reps
  • Comes in a nice selection of flavor options

Cons

  • Might not have a strong enough fat-burning effect

A lot of newcomers to pre-workouts often mistake C4 Ripped as the product they need for increased muscle mass.

What it actually aims to do is provide a blend that supports fat loss to gain more muscle mass definition.

It means that this pre-workout supplement doesn’t contain creatine to give you a strength boost. Instead, beta-alanine does the job to push you to complete more reps.

The only thing I would say is that there might be more powerful fat burners out there to consider.

This product is also featured in our articleThe Best Pre-workout for Crossfit.

4 - C4 Ultimate

Rated /5

This is by far the strongest pre-workout supplement for each one of the ingredients.

It doesn’t just provide creatine nitrate and beta-alanine, but also has a large dose of L-citrulline [1].This is known to boost levels of arginine alpha-ketoglutarate (AKG), which in turn increases nitric oxide.

The end result is a reported energy boost and improved pumps.

Pros and Cons

Pros

  • The strong formula makes this more suitable for performance athletes
  • Contains 3.2 g of beta-alanine per serving to maximize endurance
  • 6 g of L-citrulline malate per serving is the strongest we’ve found
  • Highly stimulating allowing for greater focus

Cons

  • The 300 mg of caffeine may be too much for some folks

Just keep in mind that a large amount of caffeine could cause jitters and insomnia.

5 - C4 Extreme

Rated /5

Despite the name, C4 Extreme is actually not stronger than the Ultimate option.

What it actually provides is a blend that is similar to the Original, but with some extra caffeine.

The big question is whether the added caffeine is actually worth it when the Original has you pretty much covered.

Cellucor C4 Extreme Energy Pre-Workout supplement product

Pros and Cons

Pros

  • Good option due to extra stimulants compared to Original
  • 2 g of beta-alanine claims to be enough to improve stamina
  • 1 g citrulline malate could result in better pumps and blood flowF
  • Available in large tubs of 60 servings
  • No artificial flavors

Cons

  • The price difference to Original for added caffeine is a bit high

What Are The Common Ingredients?

Supplement facts of Cellucor C4

Each product in the Cellucor C4 range shares common ingredients such as amino acid, caffeine, beta-alanine, creatine, L-carnitine, and L-citrulline. Let’s take a look at their benefits below:

1 - Caffeine

Caffeine comes with the commonly known benefit of providing mental energy and motivation. According to a study found on the National Center for Biotechnology Information website, it may also help you succeed in your fitness journey by triggering thermogenic effects [2]. This may cause additional fat oxidation to get you to a leaner appearance.

2 - Beta-Alanine

You probably won’t find any serious bodybuilders who don’t take beta-alanine. One study found on the BioMed Central website has shown that beta-alanine may improve weight training performance energy when taken in concentrated supplement form [3].

3 - Creatine

Creatine is an ingredient that has been shown to impact muscle mass power and pump [4]. Based on all the review comments that we saw, this is one area where all the Cellucor C4 supplement options have a supportive formula.

Creatine nitrate is one of the newer supplement forms showing up in pre-workouts. Manufacturers claim that by binding the creatine molecule to a nitrate molecule, people will receive equal benefits from a smaller dose of creatine nitrate compared to creatine monohydrate.

- Nick Coker, Sports Nutritionist

4 - L-carnitine

The interesting thing about this ingredient is that studies have shown that it plays a key role in transporting energy stored in fat to muscles [5].

5 - L-citrulline

The benefit of this substance is that it may boost arginine AKG levels in your body, which in turn may impact nitric oxide levels. This may improve blood flow to bring more oxygen and energy to your muscles [6].

Benefits Of Using C4 Supplements

Our team here at Total Shape got together after 6 weeks of testing with clients, and we found some important benefits to highlight with the Cellucor C4 range.

First of all, we had some athletes on a daily training program who said that they had no issues taking it every day.

This may not be important for most folks, but it’s reassuring that daily use didn’t trigger negative effects.

Secondly, the powder dissolves quite easily, and you just need a mixer to create a tasty experience. That’s not the case with a lot of other pre-workouts, so it’s a plus from our perspective.

No other pre-workout supplements brand on the market has such a diverse ingredient range to cover different types of athletes. No matter what your fitness level is, you should find the right supplement for your needs.

How Long Does C4 Supplement Take To Work?

C4 supplements take about 20-30 minutes to work. This may depend on your digestive system, but we found that users report times between 20 and 40 minutes based on review comments.

I would suggest that you drink it before you leave home, aiming for that half-hour mark before you actually hit the gym for your warm-up routine. It may take a couple of days to fine-tune the timing, and I would suggest making 5-minute adjustments to get the perfect timing.

Can You Stack The C4 Supplements?

Yes, you can stack C4 supplements, as the company has modified the formula of each version to allow for easier stacking. Cellucor also has other well-known supplements on their website that may help you achieve your goals faster.

It would certainly be a good idea to stack your pre-workout with a recovery shake.

One thing I would say though, is that if you’re planning a cutting phase, then rather than stacking the C4 Ripped, you may want to consider some of the other fat burners available that I have recommended before.

Other reviews on popular pre-workouts on the market:

Testimonials

"Excellent pre-workout for muscle growth and weight reduction. Including creatine moderates the taste, ensuring it's not too overpowering. I've purchased this multiple times and will continue to do so! I've lost approximately a total loss of 15 pounds so far! Cheers!" - Faith, from Kansas

"Reasonably priced. The pre-workout's potency seems to have diminished over time." - Dogparkdutch, from Florida

Cellucor C4 Pre-Workout does not increase testosterone. Only one version called C4 Ultimate Power contains ingredients that may boost testosterone levels.

Beyond enhancing gym performance, Cellucor C4 can impact daily energy levels and mood, providing a boost that extends throughout the day. However, it's important to note that it might also affect sleep patterns if taken late in the day due to its caffeine content.

Our Verdict on Cellucor C4 Pre-Workout

Based on our team’s test results, I think that in most cases, you will be best off with the C4 Original Pre-Workout.

Yes, it’s not the strongest one available, but unless you’re constantly doing high-intensity training or you’re a professional athlete, the blend will be strong enough for optimum results, like noticeably increased blood flow and power output.
