A new kid on the block is always the source of some intrigue for us, which is why we have created this PreFierce review today. 

We always make time for supplements with a difference, so is this product capable of giving us the energy for those big pumps in the gym? 

To impress, it is going to have to do more than that but we have been hearing good things about this product. Since it is made by a new but seemingly reputable company we are excited to see what it has in its locker.

We’re expecting all of the following from the ingredients:

  • Increased energy
  • Laser focus
  • Fat loss benefits
  • Added endurance
  • No side effects

Let’s see if it can live up to expectations.

PreFierce Ingredients

PreFierce Pre Workout ingredients review
PreFierce Review of Ingredients

The first impressions are good. There are no proprietary blends to deal with. This means we get to see all the ingredients and dosages with nothing hidden.

Because of this, we can see if this pre-workout is safe to consume, and effective. This is vital because too many products are using them which can mean you are getting a sub-par product that doesn’t work or one with dangerously high amounts of certain ingredients.

TruFierce recommends taking this 15-30 minutes before your workout.

L-Citrulline D-Malate

One of those ingredients you hope to see in a pre-workout, it’s a good start.

Because of the research and backing for its effectiveness, it is great that they have opened with such a reliable ingredient. Anyone looking for those huge muscle pumps needs to get a good dose of this into their body before a workout.

This amino acid is a proven validator that increased blood flow and oxygen levels in your muscles. This is what syphons out lactic acid as it builds, leaving you with added functionality.

The added blood flow means you can operate at your peak for longer, and hit new highs as numerous studies have shown. 

Derived from watermelons and converted into arginine in the body, it is the sign of a good pre-workout.

With 7,000 mg included, you are getting a huge dose of an effective ingredient. 


Because Beta-Alanine can raise stamina levels, it is a popular ingredient in sports supplements as you will find you can operate at peak levels for longer with this in your system.

The dosage of 3,500 mg is a generous one and when combined with the other ingredients we’ll take a look at in our PreFierce review, it is clear to see it will be of benefit.

It is sometimes linked to a tingling sensation called paresthesia. This is mild, tends to go away pretty fast, and only happens with some people. 

The dosage is important as if it is sensibly dosed, you shouldn’t notice any difference. It has a string of backing for its effectiveness as it produces carnosine. This is what can ensure your muscles have lower acidity and reduces fatigue.

Caffeine Anhydrous

Your energy needs to come from somewhere, so, why not a quality source of caffeine?

This is pure caffeine with no junk in it so it will deliver a clean energy source. Not to mention, the benefits include laser focus so you won’t be sat at the tip of the bench scrolling for an age.

It is fast-absorbing and will get to work quickly so when you arrive at the gym, it is ready when you are. 

Your output will be noticeably different when you start consuming this premium caffeine variant, especially given the potent 250 mg dosage.

This should be well tolerated by most people although some might need to build up their tolerance. Start with half measures if you aren’t used to the caffeine and work your way up to full dosage. 


An ingredient you almost expect to see around stimulants such as Caffeine.

L-Theanine allows you to stay in control as the caffeine works it’s way around your body. For a smooth energy source, it is near-essential. Its high dosage ensures you don’t crash or feel jittery which is where a lot of other pre-workouts let themselves down.

Derived from Green Tea Leaves, it helps to boost your mood and keep you focused. According to it is synergistic with caffeine as it promotes relaxation without drowsiness. 

Because they are giving you 250 mg, it is on par with the caffeine content for a smooth energy boost where you stay in control.

Betaine Anhydrous

Another quality ingredient, our PreFierce Pre Workout review is showing all the signs of a top product.

We have added energy, but for more endurance and extreme muscle pumps, this has the backing of numerous studies to warranty its place here.

Sourced from beetroot, it promotes protein synthesis and has links to creating creatine which is why it has a similar effect. It ensures the cells are hydrated which can reduce stress on them, especially important when it comes to an intense workout. 

This version has been tailored for absorption so it will get to work fast. With a dosage of 2,500 mg included, there is no reason why it won’t.

VASO6 Green Tea Leaf Extract

This is a patented ingredient and part of what makes this pre-workout unique.

It takes the most effective part of Green Tea and gets them into your system so you get the benefit of the enhanced blood flow that it creates.

As a nitric oxide booster, it is impressive and can help to boost those pumps. The 150 mg included seems to be an effective amount.


Working as an arginase inhibitor, L-Norvaline preserves nitric oxide levels.

This means added strength and enhanced endurance among other benefits. It protects the arginine levels which leads to the above benefits. 

The 60 mg included is all you need to give those big pumps what they need. This is the sort of ingredient that will bring out those veins you didn’t even know existed.

Acetyl L-Carnitine

This is an amino acid that preserves the health of your muscles as you put them through hell. 

It also increases energy levels and works as a fat-burning ingredient via its metabolism-boosting effect. This will help you to maximise your time in the gym and get shredded.

According to WebMD Acetyl L-Carnitine is an important ingredient for many other benefits including muscle movement, heart function, and brain function among others.

The 500 mg included is another optimal dosage.

Coconut Water Powder

Because you are going to push yourself in the gym, your body needs to hydrate to remain fully operational.

Coconut Water Powder is well known for its hydrating properties via the electrolytes that it has in abundance. This version is fast absorbing so although you only take this supplement 15-30 minutes before hitting the gym, it will give you a head start on your hydration.

It is also full of B-vitamins such as riboflavin, niacin, folates, and many more.

With 300 mg, you are getting plenty of it.

Black Pepper Fruit Extract

This is a neat addition that you often find at the end of a long list of quality ingredients because it can enhance their benefits. 

Sometimes known as Piperine, it makes the ingredients easily absorbed as well as more effective. The 10 mg is a generous amount and a good product to end on.

Other Ingredients

Artificial Sweeteners and Color

Whilst that’s the end of the pre workout formula – which is definitely impressive and well dosed, some of the other ingredients listed raise an eyebrow here at CleanLeanMachine. As our name indicates, we love clean and lean formulas, so slightly disappointed about TruFierce’s use of Acesulfame Potassium and Sucralose – 2 artificial sweeteners, as well as FD&C Red #40 coloring.

That’s on top of natural flavoring and pineapple fruit powder – PreFierce might have earned itself the winning position on our Top 5 Pre Workout supplements list if they could have found a way to sweeten it naturally. But these ingredients are all well within the safe daily guidelines so for most gym junkies it won’t be a problem.

Anti-caking agents

There’s also the important inclusion of silicon dioxide and calcium silicate. Although we’d love to have a simple formula, these are actually a great inclusion, as we’ve seen and tested several other pre workout supplements over the years which either arrive clumped up and stuck together, or the powder gradually cakes and sticks into a big lump before you get through the whole tub – not what you want so this shouldn’t happen with PreFierce. Nice!

How To Take PreFierce Pre Workout

The company recommends taking this pre-workout 15-30 minute before you train. 

Start with a half scoop, especially if you are not used to the caffeine content and work your way up to a full scoop. Mix with 10-14 oz of water. One thing we noticed was that each scoop is pretty much double that of your standard pre-workout.

This is because of the generous doses they have included so it’s hardly surprising. 

We don’t think you’ll have any issue getting on with the taste as we found its gummy bear flavor to be one of the best tasting out there. 

PreFierce Review: Side Effects 

Because there are no proprietary blends, we get to consider the benefits and side effects so it is easy for us to say that this should be well tolerated by most people.

Caffeine Tolerance

For those who are used to taking pre workout supplements, the 250mg included here won’t be a problem. Anyone who is particularly sensitive to caffeine should work their way up, increasing the dosage slowly until they reach a full scoop. Otherwise, you may find that you suffer anxiety and agitation among other things if you don’t usually tolerate caffeine well.

The use of artificial sweeteners (Acesulfame Potassium and Sucralose) and coloring (FD&C Red #40) could cause minor side-effects such as headaches in a small minority of people, but have been deemed totally safe in these tiny quantities by the FDA, so not as much to worry about as some people like to make out and have the added benefit of being 0 calories, compared with sugar.

The inclusion of Beta-Alanine might cause a tingling sensation in some. For the most part, this is a mild distraction and because of the likes of L-Theanine, we think anyone who takes it should stay in control pretty easily. Again, shouldn’t be a problem and can actually help you feel like the pre workout is kicking in!

The ingredient formula is decent so there isn’t anything shocking but just watch out for your caffeine tolerance or if you have noticed issues with sweeteners in the past.

This is definitely a good choice if you want massive muscle pumps and a good surge in energy to get the max out of every workout.

Whilst there are no proprietary blends to worry about, the only thing we at CleanLeanMachine dislike is the fact they used artificial sweeteners and color – but they’re totally safe so this shouldn’t be a problem for most!
