C4 vs Assault

I know how tough it can be to choose supplements with so many alternatives claiming to be better than others. You’ve probably been in a situation where you have been stuck between two seemingly great choices.

Over the years, I’ve been in similar situations, and with time, I worked out a system using in-depth research and comparison to determine the best options.

What I intend to do in this article is walk you through the very process that has worked for me while using two great products – C4 vs. Assault as a case study of sorts.

C4 vs. Assault General Overview

Cellucor and MusclePharm are fitness nutrition companies responsible for producing pre-workout supplements up for review in this comparison. The former is the producer of C4 pre-workout and has over 20 years of experience in the sports nutrition industry, while the latter was established in 2006 and has since manufactured several sports nutrition products, including Assault pre-workout. 

This overview will discuss the special features of C4 and Assault and also highlight their similarities and differences to help you make a well-informed decision. 

Overview of C4

Cellucor C4 Original is a pre-workout supplement that combines the goodness of carnoSyn beta-alanine, creatine nitrate, and caffeine anhydrous into a formula blend to improve muscular endurance, enhance energy, and pump. 

With a caffeine content of 150 mg, Cellucor C4 Original is suitable for beginners and advanced athletes looking to up their fitness game. It comes in various flavors that are great tasting and highly effective. Some consumers may feel a tingling sensation for a few minutes after using the product due to the beta-alanine present in it.

C4 also contains other ingredients that are vital for fitness and overall health. Among these ingredients are: 

  • Ascorbic acid
  • Niacin 
  • Vitamin B6
  • Vitamin B12
  • Citrulline Malate

It also contains 200 mg of caffeine for increased energy, 150mg of acetyl-l-carnitine for better blood circulation and focus, and a vitamin blend for reduced cell damage. It comes in three great-tasting flavors -watermelon, blue raspberry, and fruit punch. It contains zero calories and sugars, making it ideal for people on low-calorie diets. 

Other ingredients in the Assault formula include: 

  • Vitamin C, E, B6, and B12
  • Calcium 
  • Sodium 
  • Betaine anhydrous 
  • L-glycine
  • Taurine

Comparing C4 and Assault

C4 and Assault are pre-workouts that offer pretty much the same benefits. They can therefore be expected to share some similarities. However, they also have specific differences that set them apart. Here is a quick comparison between both products:


  • Both products are pre-workout supplements targeted at enhancing physical performance during workouts. 
  • Both come in tubs of 30 servings.
  • Both have a few common ingredients: beta-alanine, caffeine, and Vitamins B12, B6, and C.
  • Both products come in a powdered form.
  • Both products are available in different flavors.


  • Assault is slightly more expensive than C4.
  • C4 has a scoop size of 6 g, while Assault has a scoop size of 11.5 g.
  • Assault has a caffeine content of 200 mg, while C4 has a caffeine content of 150 mg.
  • C4 has a larger flavor variety than Assault.

Major Distinguishing Factor

The primary distinguishing factor between these products lies in their ingredient list. Both have a formula blend that is mainly made up of different ingredients. Although they share a few ingredients in common, such as caffeine, beta-alanine, and a vitamin blend, these shared ingredients differ in dosage. 

C4 contains 150 mg of caffeine, 1.6 mg of beta-alanine, and 250 mg, 3.4 mg, and 60 mcg of vitamin C, B6 and B12, respectively. Assault contains 200 mg of caffeine, 1.75 g of beta-alanine, and 300mg, 20mg, and 50 mcg of vitamins C, B6, and B12. 

When to Use C4

This pre-workout supplement is ideal for beginner and seasoned athletes looking to gain more energy, pumps, and endurance while they train. It contains a blend of 150 mg of caffeine, velvet bean seed extract, and theacrine, which provide an explosive energy burst. 

It also has many flavor options, making it ideal for exploring different taste profiles rather than being confined to one.

When to Use Assault

This product is ideal if you want a supplement with a high caffeine content for extra energy. Containing 200 mg of caffeine, this pre-workout will give you the strength and endurance you need for any workout session, no matter how intense. 

It is also great for people looking to reap the benefits of a vitamin blend, as it contains sufficient vitamins C, B6, B12, and E. 

Which Pre-workout Is Better?

C4 and Assault both have their unique benefits, regardless of the differences in their makeup. C4 contains a special blend of caffeine, velvet bean seed extract, and theacrine targeted at providing an energy burst. In the same vein, Assault contains caffeine, acetyl-l-carnitine, and betaine, targeted at improving focus, blood circulation, and overall performance. 

Consider your personal preference, health status, dietary requirements, and budget to make the right choice. 

Can a Beginner Consume These Pre-workouts?

Yes, C4 and Assault can both be consumed by beginners. However, due to its higher caffeine content -200 mg- Assault may be too much for beginners who have not built their caffeine tolerance. C4, however, contains a moderate caffeine content of 150 mg, making it more suitable for beginners with lower caffeine tolerance. 

Are There Side Effects to Consuming These Pre-Workouts?

Many consumers have reported feeling a temporary tingling sensation after consuming C4. However, according to Cellucor, this side effect is harmless and is only a result of the beta-alanine present in the product. Other side effects from consuming these workouts may be caused by caffeine or stimulant sensitivity, including anxiety, insomnia, and headache. 

Which of These Products Is More Affordable?

When it comes to price value, C4 is more affordable than Assault. This price difference may range between $3 – $6, depending on where you purchase them. However, when it comes to quantity, Assault is better. Although they both contain 30 servings per tub, Assault comes in a bigger tub and with a bigger serving scoop than C4. 

Final Verdict

Both products are highly effective pre-workouts, each with peculiar benefits. While C4 may be a good choice for beginners who need extra energy and endurance, Assault may be better for people looking to improve their focus and quicken recovery. Remember to consider your dietary needs, fitness goals, and tolerance levels when deciding which is best for you.
