4 Gauge is a 4 in 1 pre workout supplement that can help you push harder in the gym. It is one of the safest and yet strongest formulas on the market

What is 4 Gauge

4 Gauge pre workout supplement comes in a red container that looks like an oversized shotgun cartridge.

That alone makes it a product that grabs the attention.

Pre-workout supplements are taken shortly before a workout or other exercise activity.

Some athletes also use pre-workout formulations before doing sports such as football or rugby.

In a nutshell, supplements of this nature aim to prime the body for peak performance.


Buy 4 Gauge supplement

4 Gauge is available to buy in the US, UK, Canada, Australia and mainland Europe. Orders are placed via the official website only.

If you are a gym-goer hoping to increase your muscle strength and bulk, a good pre-workout can help.

By enabling you train with more intensity, this type of supplement allows you to work your muscles harder.

In so doing, they help you to breakdown extra muscle tissue. This, of course, enhances the need for muscle repair (growth).

Will 4 Gauge really help you start your workout with a bang and keep you firing on all four cylinders until it’s done?

The good news is, feedback and customer reviews from 4 Gauge users suggest it can.

On the face of it, this looks like a very good supplement to buy.

But who makes it, how safe are the ingredients, and is there anything else potential users may need to know?

In this 4 Gauge review, I’m going to take a look at all the information available, check the facts, and answer all the important questions potential users may have.

Who Makes 4 Gauge?

4 Gauge is a Roar Ambition product. It’s a British company that works out of a head office in Leeds.

The first thing to know about Roar Ambition is, it’s a real company that’s registered in England and Wales. The registration number is 08953534.

You can check this with Companies House if you wish, but there is no need. I’ve already done so.

Everything about Roar Ambition is legit. It was incorporated in March 2014, and all important details are up to date.

The fact that it’s so easy to find out information about Roar Ambition is good.

Pre Workout Supplement

There are far too many supplements on the market that are being sold with some very big promises, but minus any information about who makes them or where they come from.

When such supplements fail to work or make someone ill, it can be extremely hard to do anything about it.

Reputable companies don’t behave in this way.

The other thing to know about Roar Ambition is, it’s not a one-hit wonder. The company produces several other products including an incredibly popular fat burner called Instant Knockout that has its roots in the fighting sports.

It’s helped a lot of people to get the shredded, defined physique they craved.

Instant Knockout was actually the company’s flagship product, but the fact that it’s proved to be so successful will not make me don the rose-tinted sunglasses. Nor will the company’s good reputation.

Every supplement I review has to stand or fall on its own merits. However, at this point of the game, everything continues to look good.

4 Gauge Benefits

As is often the case with supplements in general, Roar Ambition has got a little creative with some of the claims it’s making:

  • Load up your guns
  • Enjoy explosive training sessions
  • Blow your previous workout apart

All this is a good fit for the appearance of the product. There’s nothing wrong with this approach.

It’s basically just a way of saying 4 Gauge will help you to train with extra intensity.

The more down to earth claims are:

  • Provides incredible energy
  • Increases stamina
  • Improves mental focus
  • Helps you enjoy amazing workouts
  • Supports massive strength gains and superior muscle growth
  • Allows you to train with enhanced strength and endurance
  • Get heads turning with your new physique

Get heads turning with your new physique? Yep! That last one sounds like more hype.

The thing is, if the product really does help you to train harder, presuming your diet is good, you should get a better physique.

Training hard and eating right will do that to you and, unless you favor ultra baggy clothing, heads may very well turn.

4 Gauge Dosage and Usage Guidelines

4 Gauge isn’t a pill-type supplement. Like a lot of other pre-workout formulations, it’s a powder. You have to mix it with water and drink it.

The drink is easy to make. It’s just a case of combining two scoops of the formulation with 300-350 ml of water. If you want you can substitute the water with a fruit juice of your choice.

The best time to take 4 Gauge is 20-30 minutes before training. Doing so will allow you to have the optimum amount of active ingredients in your blood when you are working your muscles.

In situations where a more extreme energy boost is required, it’s permissible to double the dose of powder. However, if you are a new user it’s best to see how you go with the normal dose first.

If you are using 4 Gauge long-term, Roar Ambition suggest taking a 7-day break after each 6-8 weeks of use.

Ingredient Profile

One of the good things about Roar Ambition is it’s very open about what the product contains and how much is involved.

A lot of other supplement manufacturers hide their ingredients in proprietary blends. In many cases, it’s an excuse not to divulge the weights and measures.

Proprietary blends make it very difficult to evaluate product potential. Some companies using such blends may use good ingredients, but the amounts are minuscule.

That’s why some supplements that appear to contain good ingredients don’t work.

Because Roar Ambition discloses a full and accurate ingredients profile, it’s easy for me to see, the potency is good.

Each 2-scoop (14g) serving of 4 Gauge provides:

  • L-Citrulline Dl-Malate (6000mg)
  • Creatine Monohydrate (1000mg)
  • Acetyl L-Carnitine (500mg)
  • Red Beetroot Extract (300mg)
  • Coconut Water Powder (300mg)
  • Caffeine Anhydrous (150mg)
  • L-Theanine (200mg)
  • Rhodiola Rosea (Root) Powder (100mg)

It’s nice to see Roar Ambition hasn’t tried to throw in everything but the kitchen sink. 

This has made it possible for the company to provide a combination of eight good ingredients in effective amounts.

A Look at the Formulation in Detail (What the Ingredients Do)

L-Citrulline Dl-Malate & Red Beetroot Extract

I’m grouping these two ingredients together because they share a similar, very important ability—the are nitric oxide (NO) boosters.

L-Citrulline Dl-Malate is an amino acid that is often associated with watermelons. This is due to the fact that it was first isolated from the fruit. Beetroot is a popular root vegetable that should need no introduction.

Believe it or not, beetroot boasts an exceptionally high nutritional value. It’s low in fat, high in vitamins and minerals, and is also packed full of antioxidants.

However, despite its many virtues, it’s the NO boosting ability of beetroot that’s important here.

By boosting NO levels, L-Citrulline Dl-Malate and beetroot form a winning team that improves the circulation via the process of vasodilation.

This slight dilation of the blood vessels reduces blood pressure and helps the heart to pump extra oxygen and nutrients to the muscles. The brain and major organs benefit from this improvement in circulation too.

Strenuous exercise causes lactic acid to build up in the muscles. Among other things, lactic acid causes the burning sensation and fatigue that forces you to stop and take a rest.

By helping to provide the muscles with extra nutrients and oxygen, these two natural vasodilators delay lactic acid build up, helping you to work your muscles hard and do so longer.

Creatine Monohydrate

Creatine is a popular muscle-building ingredient. There are other versions, but the monohydrate form appears to be the superior form.

Scientists discovered the value of the ingredient back in the 1970s. However, due to the popularity of steroids, nobody really bothered fully exploiting the value of creatine until the 1990s.

Although creatine is good for delivering extra muscle bulk, it also fights fatigue and improves physical performance.

Caffeine & L-Theanine

Caffeine is a stimulant that’s naturally-occurring in coffee, guarana berries, and many other plant sources.  L-Theanine is an amino acid you can obtain from green and black tea. I’m looking at them together because they have a symbiotic nature.

In fact, due to the benefits they can provide when paired, caffeine and L-Theanine are often used together in supplements. This combination is sometimes called Smart Caffeine.

Although caffeine is generally praised for its ability to increase energy and boost mental focus, it also has many other virtues. For instance, caffeine is a proven metabolism booster. That’s why it’s such a popular diet pill ingredient.

When used alone, L-Theanine produces a state of mind that is sometimes called an “alert calm”. Basically, it calms the mind without causing sedation.

When caffeine and L-Theanine are combined things become especially interesting.  Research suggests L-Theanine may change the pharmacological profile of caffeine.

Together, this “smart” combination has been shown to speed reaction times and reduce fatigue without causing headaches.


Acetyl L-Carnitine

Acetyl L-Carnitine is an energy-boosting amino acid. Research suggests it can delay the onset of both mental and physical fatigue.


This is an ability that makes it an excellent companion to the other ingredients in the 4 Gauge pre-workout formulation. And let’s not forget, Acetyl L-Carnitine assists protein synthesis too.

Coconut Water

You don’t see coconut water in many pre-workout supplements. Not yet, anyway. However, it’s inclusion here makes a lot of sense.

Coconut water helps top up the body’s levels of the important minerals that can be lost via sweat. These minerals act as neurotransmitters. If you lose too many, your training will suffer.

Coconut water is a little like Mother Nature’s equivalent to a sports drink. In fact, some people actually drink coconut water in preference to such drinks.

Rhodiola Rosea

An adaptogen herb that has the potential to do many good things for your body. It can benefit your temperament too by warding off stress.

Roar Ambition’s decision to use it here is a good one because the herb has the ability to improve exercise capability and endurance.

Does 4 Gauge Cause Side Effects

No side effects have been reported. All the things people are saying about 4 Gauge are incredibly good.

However, as with any food supplement, common sense is advised. The formulation is not going to be suitable for women who are pregnant or ones who are nursing a child.

People who have existing health problems need to be extra cautious too and check with their doctor first. Again, this is just common sense.

Other Things to Know

4 Gauge is produced to high-quality standards in cGMP-approved facilities and the formulation does not contain any sweeteners of artificial ingredients.

On a more negative note, the only flavor choice is Fruit Burst.

Unfortunately, this is unlikely to change. Roar Ambition states it’s only offering one flavor because it likes to keep things simple and Fruit Burst tastes great.

That, of course, is always going to be a matter of opinion. So, if any customers don’t like the flavor and stop using 4 Gauge for that reason, the company will have done a good job of shooting itself in the foot.

Does 4 Gauge Work – Verdict?

4 Gauge is a good product that should do everything Roar Ambition tells you it will. It contains an advanced blend of natural ingredients capable of enhancing performance and delaying fatigue. In so doing, it will surely help you to train with added intensity.

Set it up head to head with most alternative products and 4 Gauge doesn’t just beat them, it blows them away. If you need a good pre-workout supplement you won’t find a better way to “load up your guns”.

The lack of flavor choices is disappointing, but mixing the powder with different fruit juices could be a good way to add a little variety and modify the taste.

Where to Buy 4 Gauge

It would be great if you could just pop to a local store and stock up on powder but, in this case, that’s not how it works. You can only buy 4 Gauge online and there’s only one place to go. Roar Ambition handles all sales and distribution itself.

In keeping with the overall marketing theme, a tub of 4 Gauge is referred to as a shell. Each one contains 20 servings and costs just $45 a pop.

There are also generally bulk-buy deals available. The nature of the offers can change from time to time so the best way to get up-to-date information is to visit the official 4 Gauge website.

How long do the smart caffeine benefits last?

This can vary. It depends on the individual. However, between two and four hours is a good benchmark figure.

Is 4 Gauge available on autoship?

No. Each purchase is a one-off purchase. Autoship agreements are fraught with problems and tend to inspire mistrust. For this reason, Roar Ambition has made the wise decision of not selling any of its products in this way.

Can I buy 4 Gauge on Amazon or eBay?

Roar Ambition does not sell 4 Gauge or any of its other products via Amazon, eBay, or any other online marketplace or store. If 4 Gauge appears to be for sale on such sites it’s likely to be fake and should be avoided. Fake products may look the same, but they don’t have the same formulation of ingredients (no matter what the tub says) and are incapable of providing the same results.

I want to get ripped, does 4 Gauge help with fat burning?

The formulation contains caffeine. Research shows caffeine boosts metabolism and fat burning. However, any fat burning benefits will be secondary in nature. Fat burning is not what this product is for. If you want something to use during cutting cycles or help you to lean up, there are better options available. 4 Gauge is for people with a desire to train harder.

Do I still need to take 4 Gauge if I’m not training that day?

No. It’s a product that gets you fired up and ready to go. If you have nowhere to go there is no need to bring out the big guns. What would be the point?

Can women use 4 Gauge too?

Yes. It’s for anyone who wants to improve their training capabilities. Sex does not come into it.

Is the product only for bodybuilders?

No. It’s for anyone who wants to enhance their energy, focus, and training capabilities. Although many bodybuilders use the product, it’s equally good for any number of sporting activities such as circuit training, martial arts, and running track.
