C4 Ultimate Pre Workout Review – Product Overview

C4 Ultimate Pre Workout - lightening boltC4 Ultimate is an intense, athlete grade energy combination packed with 300mg of Caffeine as well as plenty of Amino Acids such as Creatine and Beta-Alanine.  This is a high energy, sugar-free version of the C4 original by Cellucor, possibly the best known pre workout brand worldwide.

Because this brand gives such great results, I’ve spent considerable time researching C4 Original Pre Workout, C4 Energy Drink and C4 Shred on this website.

Ultimate is truely an energizing, motivating and strength building pre workout.  I tend to switch between some of my favorite pre workouts to keep it interesting, but C4 Ultimate is at the top of my rotation for one of the best supplements.  Ultimate is very strong in both taste and results.  It seems to help me get an intense workout every time.

When I don’t have time to stop home to mix my powder pre workout, they even make a C4 Ultimate “On the Go”.  Personally, I have enjoyed several of the other products in the C4 line over the years, but C4 Ultimate is a step up from the others in several ways (price being one of them).

Some of the other C4 products may suit you better, therefore I will briefly describe these here to see if they fit your needs.  I will go over the benefits and any downsides of this popular pre workout.  I’m also going to go over the ingredients that set C4 Ultimate aside from other store brand pre workouts.

This review wouldn’t be complete without telling you about my personal experience with C4 Ultimate.  Pre workouts are not a “one size fits all” supplement.  All of our bodies react differently to certain ingredients, and we have different goals in mind when it comes to exercise.  Hopefully this post will give you a better idea if C4 Ultimate will work for you.

C4 Ultimate Pre Workout Review

C4 ultimate pre workout - jelly bean flavors

C 4 Ultimate comes in a variety of sugar free flavors.  Cherry Lemonade, Icy Blue Razz, Orange Mango, Strawberry Watermelon and Gummy Candy.  This time the Strawberry Watermelon sounded best to me.  Ultimate is free of any artificial flavors and dyes which makes this a natural pre workout.  Because of this, the flavors are not overpowering or overly done.

C4 is sweetened with Sucralose which I will talk more about in the ingredients.  The flavor tastes good, yet strong tasting since it is so packed with Caffeine and Amino Acids.  It seems to mix well with about 10oz of water and a couple of ice cubes (directions say 1 serving to 6oz of water).

Since this is not my first time trying C4 Ultimate, I used a little more than 1 serving.  If you are not used to taking pre workouts, Always start with less than a serving your first time.  Otherwise you are almost guaranteed discomfort, headaches or the jitters.  The only that pre workout is bad for you, is when overused.

My normal routine is to drink my pre workout right before I leave my house.  This way it is starting to kick in when I get to the gym.  By the time the warm-up is over, I’m all in.   C4 Ultimate has a large amount of Caffeine, so I can feel that kick first, then the head tingle from the Beta-Alanine.

C4 ultimate pre workout - animated character shoulder pressThe most important benefits are felt as I begin my exercise routine.   It feels as if I can push and pull more weight, also I don’t need nearly as much resting time between sets.  The strong Amino Acids are helping to recharge the muscle after each set.

This keeps me from fatiguing during my workout.  I can tell that I have more endurance.  This effect is coming mainly from the Creatine, another popular Amino.

I prefer to do a Crossfit type workout by jumping from exercise to exercise while keeping my heart rate up.  Today my C4 Ultimate stayed with me for the entire hour of intense exercise.  Then 15 minutes on the treadmill for a little bit of Cardio.  I could have gone longer without fatiguing, but I choose not to overdo it today.

Next, I head home for my post workout protein powder shake which helps to recharge my muscle tissue and speed up muscle recovery.

C4 Ultimate Ingredients

C4 ultimate pre workout - caffeine signCaffeine Anhydrous:  An incredible 300mg of fast acting energy.  Twice as much as a lot of other pre workouts.    Caffeine is the best natural energy and pre workout fat burner available.  It contains thermogenic calorie burning properties.  It motivates and brings mental alertness.  Caffeine also improves focus and increases reaction time.  Be wary if you are Caffeine intolerant.

Theacrine:  Also named TeaCrine, many pre workouts use this natural stimulant for extended energy.  There are studies that suggest our bodies don’t adapt to TeaCrine as quickly as Caffeine.  This prolongs the “Caffeine tolerance” of this ingredient.

Nitramax NO3-C:  The Ultimate line prides itself on this Nitric Oxide support.  It is an advanced compound delivering a dual pathway Nitric Oxide. Unlike L-Citrulline which synthesizes into Nitric Oxide, NitraMax supports two different forms of Nitric Oxide giving the ultimate pump.C4 ultimate pre workout - creatine molecule

2g Creatine Complex:  Creatine supports muscle energy production and is proven to increase strength.  It can be used pre or post workout to build muscle size.  Creatine is an amazing Amino, but some are intolerant to it.  If you happen to be one of these, Creatine Free Pre Workout Powders are available.

3.2g Carnosyn Beta-Alanine:  This is the Amino Acid that gives you that harmless head tingle so you it’s working.  This Amino is known to fight fatigue and increase muscular endurance.

L-Citrulline, Citrulline Malate, Citrulline Nitrate:  These are also Amino Acids that synthesize to increase Nitric Oxide levels.  This increases muscle pump and helps fight fatigue by bringing Oxygen and nutrients to the muscles.

C4 Original Pre Workout

C4 ultimate pre workout - shaker with C4 pre workoutC4 original Pre Workout is Cellucor’s first and best-selling pre workout.  For many of us, C4 Original was our first love in a pre workout supplement.  Many other products have come and gone, but this one still remains to be a great formula for both beginners and intermediate.  C4 Original does not contain any natural flavors and is sugar free.

It contains 150mg of Caffeine, which is about average for some of the other top workouts.  This quantity makes it not as “over the top” for some.  C4 Original also contains TeaCrine, a natural Caffeine made from the tea leaves.  The best part is that is still has the high amounts of the critical Amino Acids for that pump and to enhance performance.

C4 Original pre workout has all of the Amino Acids that you need to get vascularization and an intense workout, without getting over Caffeinated.  The Original does not contain the same amount of the ingredients as C4 Ultimate, but still includes the key Aminos such as Creatine, Nitric Oxide and Beta-Alanine.

C4 Original will still do the trick even though it is the least expensive in the C4 line.  For more information on the Original, here my post on the C4 Original Ingredients.

C4 Ultimate and C4 Original “On the Go”

C4 ultimate pre workout - C4 on the goC4 Ultimate “On the Go” is an excellent way to get your pre workout in a can if you don’t have time to mix your powder.  The carbonation in this is a very refreshing difference and makes it even easier to go down.  This little package comes with the same 300mg of Caffeine and Amino Acids as the C4 Ultimate powder.

There is also a C4 Energy Drink for the Original available if you don’t need quite as high of an energy rush, but still want to have an intense workout.  I’ve been known to drink a can of this for an afternoon pick me up.

Both of these C4 Energy Drinks are made without any artificial flavors and are sugar free.  These C4 drinks are an excellent choice, but they do come with one drawback.  You will not be able to adjust the quantity of ingredients for the strength or flavor that you are looking for.  I prefer this sometimes, since I usually take more than 1 serving at a time to get that extra pump.

The price of convenience is not bad either, for less than $3.00 per can if you purchase it by the case.  Convenience is key, but if you are attached to your powders, simply keep your pre workout along with your shaker in your car to mix at the gym.

C4 Ultimate Shred Pre Workout

c4 ultimate pre workout - animated man flexingAlthough regular Ultimate will help you lose fat through calorie burning, C4 Ultimate Shred takes this to a new level.  Shred contains effective thermogenic ingredients that specialize in burning fat.

It is appropriately named “Shred” since it not only has many of the same ingredients as the regular Ultimate, but it is made to heat up your body by increasing your metabolism.  This burns fat at a much higher rate.C4 Ultimate Shred Review

C4 Ultimate Shred is also made without artificial flavors and it is sugar free, but will run about $10 more per container to get these incredible thermogenic effects.  The thermogenic ingredients include ginger extracts, cayenne pepper and other natural fat burners.

This is the healthiest and the only long term way to lose weight while you get in shape.  You can reach your weight goals while getting toned at the same time!

The Ultimate Conclusion

C4 ultimate pre workout - picture of C4 ultimateC4 Ultimate Pre Workout is a top rated pre workout supplement, packed with more Caffeine and Amino Acids than any other in its class.  As I mentioned, I’m a fan of Ultimate and pretty familiar with it, and am still impressed with its performance.

The energy, motivation, and focus along with the increased stamina from C4 Ultimate will help to accomplish exercise goals with more ease.

C4 Ultimate gives a great muscle pump and will motivate you to go at it harder and longer.  This feeling will give you more confidence in your abilities and a better workout than without it.  The Ultimate ingredients that I listed are aimed at providing strength, energy, and performance.

300mg of Caffeine can be a bit much for some, so there is always C4 Original pre workout at 150mg per serving.  The Original is still packed with a similar amount of the necessary Aminos.

I recommended some of the other C4 “On the Go” products that have similar ingredients.  All of these products are aimed at athletes with different goals in mind.  They even make C4 Gummies!  I encourage you to give C4 Ultimate pre workout a try, and if you don’t enjoy it for any reason, pre workouts and other nutritional supplements come with a 30 money back, satisfaction guarantee.
