Our 4 Gauge vs EVLution Nutrition ENGN Pre Workout comparison gives us a chance to look at a couple of highly rated products.

Which of them is going to give us what we need though? We have reviewed some of the industry’s biggest brands, but even these can be overrated.

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 it really won’t bode well.

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

4 Gauge vs EVLution Nutrition ENGN Pre Workout: Who Makes These Products?

Roar Ambition4 Gauge Pre Workout Supplement

Here we have the UK based company behind 4 Gauge.

With a load of 4 Gauge before and after profiles being posted online, it is clearly a favourite among a lot of people.

There is a generous money back guarantee and they ship directly from both the UK and USA.

In terms of endorsements, theirs are pretty impressive. UFC fighter Diego Sanchez put his name to this product. Then there is former MR. Universe Robby Robinson who endorses their T booster TestoFuel.

Evlution NutritionEVLNutrition ENGN Pre Workout

This is the Florida based company behind our second product, and they are one of the industry’s big guns.

Despite this, their website is a bit generic with the usual mission statement content as they try and put their ethos across.

With such a big company does come a wide range of products. This includes the likes of BCAA energy supplements as well as fat burners. There is also a lot of merch available.

There is also a 6-week training program on their site. They also have brand ambassadors, these include James Boggia, he seems to be a CrossFit trainer and enthusiast although it doesn’t say what he is particularly known for.

They also have free 2-day shipping with orders over $49.

Their product are mostly available online, there are a few outlets that shift their products. Despite looking around their site for a while, we couldn’t find a money back guarantee.

4 Gauge vs EVLution Nutrition ENGN Pre Workout Ingredients

This is where we can really see which of these is going to be a useful product.

The early signs aren’t great for EVLution Nutrition ENGN Pre Workout though. They put a lot of their ingredients into a proprietary blend. This means we don’t get to see all the dosages and it is difficult to see if each ingredient will be effective or not.

Still, there is a lot to go on.

Mutual Ingredients

Creatine Monohydrate

A very good start from both products, this is one of the most important ingredients for a pre workout.

It also has benefits post workout. The main use is that it can really help with lean muscle mass.  Creatine gets the support of numerous studies, it is a reliable, safe and effective ingredient.

It aids both physical and muscular performance. In terms of post workout, it is its ability to aid recovery that makes it so good. It’s never too early to get the recovery process going.

Actually, Creatine is good at helping the body at any time. One study shows how 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 really useful dosage. The 2 g in EVLUtion Nutrition ENGN Pre Workout is even better.

Caffeine Anhydrous

An important ingredient in so many supplements, but only if it is dosed sensibly.

Caffeine is actually incredibly versatile which makes it so good. This is why fat burners use it – it has metabolism boosting capabilities and nootropics can benefit from the fact that it increases focus and alertness.

Sure, it is the energy boost that makes it so good for a pre-workout. You need a reliable energy increase so that when you walk through the gym door, you are ready to go.

The anhydrous side just means that it is a powdered version and is easily absorbed, as well as fast acting.

Be careful though, a stimulant is only as good as the dosage. The sensible, safe and effective 150 mg in 4 Gauge will give you enough of a boost, without risking side effects.

The fact that it is in the proprietary blend in EVLution Nutrition ENGN Pre Workout is a real worry.It can be dosed too high meaning you are at risk of jitters, headaches, insomnia and more.


Another very good ingredient.

Because a lot of pre-workouts contain stimulants, you need nutrients that counter their negative effects. L-Theanine is just the sort of ingredient for making sure you stay calm, even when there is Caffeine in your system.

Even still, you need the Caffeine to do its job, thankfully, it brings out the best in it. Derived from Green Tea leaves, Examine.com tells us that it helps promote relaxation without drowsiness, making it synergistic with Caffeine.

The Caffeine content in 4 Gauge is actually very sensible and should still be well tolerated anyway. However, this ingredient ensures that you are having a positive experience even if your tolerance to Caffeine isn’t very high.

The 200 mg a another optimal dosage from 4 Gauge. The problem is that it is in the proprietary blend of EVLution Nutrition ENGN Pre Workout. This means we don’t know if it will work or not.

Individual Ingredients

4 Gauge


A very good start to their own ingredients.

L-Citrulline is so good because it enhances blood flow. It turns into nitric oxide in the kidneys which widens the blood vessels. Vital for the big pumps and gains – this is why we are here after all!

It is mostly found in watermelons, and converts into Arginine in the body. This is known for being useful for Creatine synthesis,  but 4 Gauge already give you a good amount of that as well.

Examine.com, advise that anything between 6 – 8 g is optimal. 4 Gauge has included an optimal 6 g making this a really positive start for them.


Anything that can keep your mind sharp is going to be useful here.

The best pre workout supplements give you these sort of ingredient. Rhodiola is a Scandinavian herb and is often credited with being able to raise spirits. Since it is important to be in the right mental shape if you want to get to the next level of your workout at the gym, it’s a good inclusion.

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

The 100 mg is a good dosage.

Acetyl L-Carnitine

Another useful one.

L-Carnitine can increase energy levels as well as boost your body’s fat burning. Any ingredient that can help you to get a bit more out of every session, as well as get you shredded, is one you should be grateful for.

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

The 500 mg is another great dosage.

Red Beet

A big trait for any pre workout is added blood flow.

Red Beet will get your plasma nitrate levels on the rise which will make your workout is even better. It is a well proven ingredient for increasing stamina levels and being a safe and natural ingredient.

Basically, those big muscle pumps and the gains will be easier to achieve.

The 300 mg is all you need.

Coconut Water Powder

Any pre-workout worth using will have you working up more of a sweat than usual.

When you do this though, your body feels depleted which can lead to it being more prone to injury.

Coconut Water Powder is great because it contains a load of electrolytes that are so important for making sure your body gets everything it needs.

Staying hydrated is crucial and this is the type of ingredient that can help for that when your body is upping the intensity.

The 300 mg is another good amount.

EVLution Nutrition ENGN Pre Workout


Simple referred to as Vitamin B3, this isn’t a flagship ingredient by any stretch.

As with many of the B-vitamins, it can help the body to break down carbs and then use them for energy. This will help to get you shredded and give you that extra output in the gym.

The problem with it is that when the body takes on excess amounts, it passes through your urine. Examine.com says that in order for it to be effective you need around a gram of it.

It’s not in the blend but we only get 35 mg.

Vitamin B6

More of the same really.

This is useful but it works in a similar way to the previous ingredient. By turning glucose into fuel it can help the user to get more out of their time in the gym. Again, it isn’t going to be the flagship ingredient in any great products though.

The 2 mg is also a bit low when compared to a lot of the competition as well.

Vitamin B12

A bit more of the same.

It can be good though simply because our bodies cannot create it naturally. If you are vegan or vegetarian then you will benefit from supplementing it because fish, meat, and dairy.

B12 is sometimes linked with mental functioning, although WebMD files this trait under their possibly ineffective for section.

At 25 mcg, it might be enough to do some good.

Folic Acid

A bit of a better ingredient because of the fact that it can help to produce nitric oxide. This is what you need when it comes to promoting muscle mass. A popular ingredient for those trying to conceive and is otherwise known as Vitamin B9.

WebMD says it is required for the proper development of the human body.

The 800 mcg is a good amount for it to have an effect.


Not the best of ingredients for a pre workout.

It can boost memory and increase attention span but this isn’t exactly what we’re here for!

This is why Choline Bitartrate is an ingredient you would usually find in nootropics.

Examine.com says that it is mostly used for either its cognitive boosting properties or as a liver health agent.

Not an ingredient to get excited about though and the dosage of 200 mg is a standard one.


An ingredient that is included to help you to stay you calm in stressful situations.

Basically, because the Caffeine content, this is a necessary ingredient. It can help you to focus even when there is a lot of Caffeine in their system.

The proprietary blend though makes it difficult to see just how much it is needed and if it will actually work.

Agmatine Sulfate

An ingredient you don’t see too often but it does get some backing.

Agmatine is thought to be able to increase blood flow and even aid muscle recovery. This makes it a useful addition. It is also thought to be able to reduce anxiety which is another good strength given the stimulants in this product.

Otherwise known as curcumin, it is a metabolite of L-Arginine. (Examine.com) It shows promise for alleviating neuropathic pain and shows some potential in benefitting cognitive health.

We don’t have the dosage again though so it is hard to say if it will work.

Mucuna Pruriens

It could be useful but mainly for testosterone.

Mucuna Pruriens can raise T levels to a normal level, but not beyond. It is an ingredient that stimulates the luteinizing hormone which communicates with the testes to create and release more testosterone.

This is good and everything, but not what we are after.


Another strange inclusion.

Definitely not the sort of ingredient you see very often in pre-workouts. Known for being a mild stimulant it has similar effects to Caffeine but there are some that dispute this. Most studies that get behind it say it can increase focus, energy as even mood.

Thought to be useful as it can widen the airways, it can help you to get more air into your system which will help with upping the intensity.

Although, one study did show that it didn’t have any beneficial effects when it came to cognition and mood when compared to a placebo and Caffeine.

Because it is a stimulant, we could really do with the dosage, but we don’t get this information once again.

Huperzine A

A good ingredient for enhancing your cognitive capabilities as well as helping you to focus.

Useful for the gym although with no dosage it is hard to say whether it will work or not anyway.


The final ingredient is this trademarked version of Black Pepper Extract.

A popular ingredient in many supplements because it has been found to bring out the best in  other ingredients. This usually improves an already good product.

The problem here is, there aren’t enough of the proven pre-workout ingredients to make it as good as it could be.

The proprietary blend stops us from knowing if it will be dosed well enough to have any impact.

4 Gauge vs EVLution Nutrition ENGN Pre Workout Side Effects

The good news is that 4 Gauge doesn’t contain anything that you should be concerned about.

Their ingredients are all sensible inclusions and the dosages are effective and within safe range.

The main concern with EVLution Nutrition ENGN Pre Workout is the Caffeine content.

The proprietary blend is the culprit and too much Caffeine can result in jitters, insomnia, nausea, headaches and a lot more.

On top of this there is Beta-Alanine. This has been found to cause paresthesia. This passes within a couple of hours but the tingling sensation can be quite distracting.
