4 Gauge vs PEScience High Volume Pre Workout

It’s Caffeine vs non Caffeine today in our 4 Gauge vs PEScience High Volume Pre Workout comparison.

That’s right, one goes down a very traditional pre-workout approach to get you that important energy increase and the other goes down a different route. But which will be the most effective for what we are after?

In order to impress, each product needs to give us the following:

  • Increased energy
  • Enhanced focus
  • Greater muscle pumps
  • Big gains!

Anything less than this and they will find it hard to win us over.

Let’s start by getting to know them a little first.

4 Gauge vs PEScience High Volume Pre Workout: Who Makes These Products?

Roar Ambition4 Gauge Pre Workout Supplement

The UK based company behind 4 Gauge have really caught the eye.

They do everything by the book which is good to see, making all their products to the approval of the FDA and GMP.

We like that Roar Ambition have a generous money back guarantee but also, that they check and amend their ingredients and dosages regularly. This means the customer is getting the best possible version at all times.

They ship directly from both the USA and the UK so getting their products to you in a timely manner is easy. Also, all their ingredients are natural.

If endorsements are something you look out for then their names really are impressive. UFC fighter Diego Sanchez puts his name to their fat burner, Instant Knockout. Then there is former Mr. Universe Robby Robinson putting his to their T booster TestoFuel.

With a load of 4 Gauge before and after profiles online, it is clear that a lot of people are seeing results.

PESciencePEScience High Volume Pre Workout

Now for the Florida based company who have been around for some time.

They have a good portion of the market meaning they can make some products such as this Caffeine free one, and see how it goes.

They dedicate a fair bit of space on their site to quality control. They discuss how their GMP facilities are legit and suggest that a lot of other companies’ aren’t.

We couldn’t find anything in regards to a money back guarantee when we looked through their site though.

Their product section has a decent range on there. They sell the likes of BCAA drinks and Joint Support formulas. They advise that this is a vegan-friendly and gluten-free product.

It does seem to sell well on Amazon, but in our experience this is not an important trait for a truly useful product. Some of the worst we have seen appear to sell well on there.

They do like a catchy tagline and they say ‘’prepare to feel the volume’’ when promoting this product. Let’s see if this is what we should expect.

4 Gauge vs PEScience High Volume Pre Workout Ingredients

Now we can really see which is going to be the better option.

The early signs are mostly good. 4 Gauge does not use any proprietary blends which mean all the dosages are revealed.

This is almost the case for PEScience High Volume Pre Workout, only 3 of their ingredients are combined in a blend and the individual dosages are not given.

Mutual Ingredients


A great ingredient from both products. This is often the first name on the team sheet and for good reason.

Citrulline is well known for its blood flow enhancing capabilities. It turns into nitric oxide in the kidneys. This widens the blood vessels which is vital for getting the big pumps and gains that we are all looking for.

A common source is actually watermelons and Citrulline turns into Arginine in the body. This is useful for Creatine synthesis. Only 4 Gauge already contains Creatine so this is probably more important for PEScience High Volume Pre Workout.

Examine.com, advise that anything between 6 – 8 g is optimal. 4 Gauge has included an optimal 6 g. PEScience High Volume Pre Workout only gives you 4 g which isn’t enough for what we need it for.

Individual Ingredients

4 Gauge

Creatine Monohydrate

A great start to their own ingredients here.

Creatine is a common ingredient when it comes to both pre and post workout. It is certainly useful for lean muscle mass. Creatine really catches the eye and has the support of numerous studies. It is an effective, and safe ingredient.

Creatine aids both physical and muscular performance and is used post workout because it is good for recovery. However, this is a process that can be started early making it good for a pre-workout to include.

In fact, it can benefit the body at any time. One study shows that supplementing Creatine during arm flexor strength training was found to lead to greater increases in arm flexor muscle strength, upper arm muscle area, and fat-free mass than strength training alone.

The 1 g in 4 Gauge is a very effective dosage.

Caffeine Anhydrous

This is an ingredient that PEScience has left out and tried to turn it into an advantage.

The problem with that is that it’s just so useful. It is also incredibly versatile. This is why fat burners use it for metabolism boosting, nootropic uses it for increased alertness and focus, and pre-workouts use it.

What we are after here, is a reliable energy increase. Caffeine is the sort of ingredient you want in your system when you walk into the gym. It can really get you psyched and ready to go from the start.

The anhydrous side of it just means it is a powdered version that is easily absorbed and gets to work fast.

Of course, any stimulant is only as useful as the dosage. Too little and it won’t work, too much and you risk side effects. 4 Gauge has included a very sensible, yet effective 150 mg.

This will be well tolerated and isn’t too much all in one go like many other pre workouts.


An ingredient that can keep your mind sharp.

You will find that the better pre workouts include ingredients that can help with cognitive boosting.

Rhodiola is a Scandinavian herb and is often credited with being able to raise spirits. It is the sort of ingredient that will get you in the right mental shape which is very important when trying to get to the next level of your workout at the gym.

Examine.com tells us that Rhodiola is popular for its adaptogenic properties (reducing fatigue and exhaustion in prolonged stressful situations).

The 100 mg is a good dosage.


An ingredient that really shows how much 4 Gauge have thought their formula through.

Because most pre-workouts contain stimulants, you will find nutrients such as L-Theanine on the label. It helps to keep the user calm, even when the likes of Caffeine are working.

It is derived from Green Tea leaves and L-Theanine even ensures that Caffeine’s positive effects last even longer. Examine.com tells us that it helps promote relaxation without drowsiness, making it synergistic with Caffeine.

The Caffeine content in 4 Gauge isn’t even that high, to be honest, but is the sort of ingredient that can ensure that anyone who uses it gets a positive experience. Everyone’s Caffeine tolerance is different after all.

The 200 mg is a good amount once again.

Acetyl L-Carnitine

Another very good ingredient.

This is because it can increase energy levels but also enhance fat burning. If you want to get more out of each session and get shredded, this is an ingredient you should be looking for.

WebMD supports this by saying that Acetyl L-Carnitine helps the body to produce energy. They also advise that it is important for heart and brain function, muscle movement, and many other body processes.

The 500 mg is another very good amount and one that will really benefit the body.

Red Beet

More blood flow is never a bad thing.

Actually, it is one of the main things we want so the fact that Red Beet will have your plasma nitrate levels on the rise will ensure your workout is even better. Also, it can increase stamina levels and what’s even better still is that it is a safe and natural ingredient.

The added blood flow is useful for the big muscle pumps and the big gains will be easier to achieve as well.

The 300 mg is another good dosage.

Coconut Water Powder

If a pre-workout is going to work, it needs to help you to up the intensity.

The issue with this is it can leave your body depleted of what it needs. This can lead to injury as well. The good thing about this ingredient is that it contains a load of electrolytes that are key to ensuring your body gets what it needs.

Staying hydrated is vital and this is just the ingredient for that when your body is upping the output.

The 300 mg is definitely a good dosage, making it a useful inclusion.

PEScience High Volume Pre Workout

Vitamin C

Not an ingredient you often see in pre-workouts.

It has some uses but isn’t exactly necessary. We get a lot of it from fruits and vegetables of course so it isn’t hard to get it into your body.

We do see the sense of it though. WebMD says it is often used to improve physical performance as well as countering the side effects of cortisone. This could mean it is good for building muscle and even testosterone levels.

Not a lot of pre-workouts include it for a reason though and it is taking up vital space in this product.

At 250 mg, it’s not the most potent amount anyway.


This could be a good ingredient to include.

Don’t mistake it for a stimulant though. A lot of people do because it is found in a lot of energy drinks. Its benefits are found on the other side of this though. Because it can help the user to stay calm and in control when there are stimulants in your system, it is a good ingredient.

As this product is stimulant free, this isn’t exactly the most important trait here.

It is thought to be able to increase blood flow so now you get a sense of why it has been included. It is also an antioxidant but the lack of human trials are what stops it from being a vital ingredient.

There are animal trials that show promise but what you really want is proven ingredients. A good source of Taurine is meat so the fact that this is vegan-friendly makes it a useful source.

The proprietary blend is a problem though. Without the dosage, we cannot see if this will be useful or not.


Not the most common ingredient, but it just might be beneficial.

One study shows how it has been found to aid water retention which can be useful during a workout.

Also, as detailed in the same article, a placebo-controlled study showed that a glycerol supplement was found to have an increasing effect on aerobic and anaerobic performance.

There appear to be some conflicting studies when it comes to this ingredient. Some find it to be useful, but other studies have shown this is not the case.

The version included is a branded type called Hydromax. It is thought to be better for hydration as well as performance and is absorbed quickly by the body.

It does have links to increasing weight. This is thought to be because of the water retention. Because we don’t have the dosage, we cannot see if it is going to help. Often included as a safe alternative to stimulants but we aren’t sure if it will work here.

Ferula Asafoetida Extract

Maybe there is something in this product that gives the user gas.

According to Examine.com, this ingredient as a supplement is catered towards lung and gastrointestinal health and is used as a carminative agent.

The continue and say it may also have benefits for cognition which would be good if it could increase focus.

It is also known as Stinking Gum, Devil’s Dung and Stinkasant – we’re not making these up by the way!

In traditional medicine, it has been used to get rid of wind from the stomach but it is often consumed to reduce flatulence. It is not a common inclusion we can tell you that, also what is it in this product that makes it a necessary inclusion?

There is insufficient evidence to back up it up as a fatigue fighter as some suggest it could be. Still, without the dosage, it is hard to say if it will do anything anyway.

Arginine Nitrate

This is an amino acid that is also worthy of a place in testosterone boosters.

It is able to increase blood flow making it another effective ingredient. IT can also benefit sexual health so it has more than one use. The problem though is that the body cannot absorb it so easily.

WebMD tells us that it is necessary for the body to make proteins. By increasing blood flow it does give us what we are after. However, WebMD also says that there is inconsistent evidence about the effects of L-Arginine on exercise performance.

It does appear to be able to the amount of time we can exercise time taking infrequently will not give you the results you want.

The 2,000 mg falls short of the examples from studies that WebMD provided but it could still be useful.

Agmatine Sulfate

Just how effective this ingredient can be is up for debate but it is something you see more often in pre-workouts.

It can increase blood flow which is always a welcome trait.

An ingredient we are starting to see more often in pre-workouts, but how effective is it? Thought to be able to increase blood flow again, it might also be able to help with muscle recovery.

Agmatine is even linked to reducing anxiety but this isn’t as important in this product because of the lack of stimulants. Once again though, the issue with it is the lack of evidence behind it.

Formed from the previous ingredient it is thought to be able to help prevent Alzheimer’s.

There are some animal studies conducted that make it worth following up with human trials, but it seems as though not many have as of yet.

The dosage of 1,000 mg appears to be within the safe range, it is unlikely that it will be effective though.

4 Gauge vs PEScience High Volume Pre Workout Side Effects

The good news is that there isn’t anything in either product that should concern the user.

All the dosages are sensible and in 4 Gauge, very effective meaning they should both be well tolerated.

Even the proprietary blend in PEScience High Volume Pre Workout seems to be fine.

Whilst both products are safe, that is where the comparisons end really.

4 Gauge took their ingredients to the next level, they include some great nutrients and have dosed everything really well.

The same cannot be said for PEScience. They have scrimped when it came to their main ingredient and couldn’t follow it up after. Their other decent ingredients are in a proprietary blend which makes it difficult to see if they would be useful or not.

4 Gauge is just a great mix of ingredients, safety and made by a reputable company. This is a combination that is hard to beat. The likes of PEScience High Volume Pre Workout come nowhere near to beating it.
