4 Gauge Review – The Pre-Workout Powerhouse


For many of us pushing hard at the gym, pre-workout supplements are a well-known corner of the supplement industry. These supplements help to boost energy levels, and give our muscles more power to push harder with each lift.

Yet with so many pre-workout supplements out there, it can be hard to focus in on the ones that actually work. Not only do many pre-workout supplements come with a long list of side-effects, many of them can be dangerous if taken incorrectly.

There is one supplement on the market, however, that is far more researched and spoken about than the common rabble of pre-workout options. That supplement is 4 Gauge, developed and sold by Roar Ambition.

We wanted to look a little deeper at this supplement, and see what all the fuss was about. So we ordered a month’s supply and begun our testing. We wanted to learn what benefits it offers, what’s inside it, what side-effects were known to be attached to it, and if it really delivered the results we’ve been hearing about.

4 Gauge – The Core Benefits

The core benefits of 4 Gauge are not that uncommon from many pre-workout supplements. The company that created 4 Gauge, Roar Ambition, states that 4 Gauge is a premium formula designed to give you the best results possible.

So let’s take a closer look at those benefits. 4 Gauge offers to:

• Increase your strength, allowing you to train harder than ever before.
• Provide a boost to your focus and mental clarity.
• Offer a low-calorie solution to a pre-workout supplement.
• Provide you with unrivaled energy levels compared to its competitors.
• Allows your body to achieve skin splitting to help your muscles pump, and look larger as a result.

A pretty straight forward approach, however having looked at many of the other pre-workout supplements on the market, it’s good to see 4 Gauge doesn’t pretend to offer you the world.

Instead the team behind 4 Gauge make some pretty basic claims, which shows us that they are confident in the supplements ability to boost your pre-workout state. Since the supplement has been on the market since 2015, there must be some truth to their success.

4 Gauge – The Ingredients

To get a better grip on how 4 Gauge provides its promised benefits, its best we step back a moment and look closer at what exactly is inside the supplement. Since 4 Gauge is marketed as a premium product, we expected to see premium ingredients.

In this regard, we absolutely did. Many of the ingredients inside 4 Gauge are incredibly high strength stimulants, or rare all-natural compounds not often seen in many other pre-workout supplements on the market.

The exact breakdown of the 4 Gauge formula is as follows:

• Coconut Water Powder – 300mg
• Acetyl-L-Carnitine – 500mg
• RhodiolaRosea – 100mg
• Red Beet – 300mg
• L-Citrulline DL-Malate – 6000mg
• Creatine Monohydrate – 1000mg
• L-Theanine – 200mg
• Caffeine Anhydrous – 150mg

To get a better idea of how many of these active ingredients play a role in the 4 Gauge formula, and how they assist you in providing you with those promised benefits, let’s take a closer look at them.

Caffeine Anhydrous

Caffeine anhydrous is a dehydrated form of pure caffeine, and is one of the most potent compounds found within 4 Gauge. One table spoon of caffeine anhydrous is equal to 28 cups of coffee.

Added to this, the compound will also slow glycogen use in the body. This results in providing you with longer bouts of energy. Understandably you can expect to feel stronger, have more endurance, and more power behind your workout as a result.

Usually it is not wise to ingest caffeine in this form. If you were to take just one table spoon of this in powder form, you could risk heart damage, or at least be awake for an unhealthy amount of time.

Yet you’ll notice that this is one of the lowest concentrations in the 4 Gauge formula for this very reason, only having 150mg in the entire supplement. So whilst it is dangerous to ingest with at high concentrations, it is quite safe in the levels found in 4 Gauge.

Creatine Monohydrate

Creatine monohydrate is a modified form of creatine, which is a naturally produced molecule in the body. The molecule stores high-energy phosphate groups in the body, in the form of phosphocreatine. This process allows the body to release energy in high-stress situation, such as intensive workout sessions.

Adding creatine monohydrate into the body will provide you with more fuel to burn when you reach these high-stress situations, which is likely the key behind the supplements increased strength whilst working out.

L-Citrulline DL-Malate

Despite its tongue twister of a name, L-Citrulline DL-Malate is one of the most common ingredients found in pre-workout supplements. The compound is a malic acid (Malate) mixed with citrulline. It is found in many fruits as a natural organic compound.

The reason for its wide spread use is pretty easy to understand. Research has shown that this compound provides your muscles with more endurance and strength, as well as higher aerobic performance.

Furthermore, it provides the body with an enhanced ability to absorb nutrients, and is twice as effective as naturally raising your nitric oxide levels to gain the same effect.

The benefits don’t stop there, with research also pointing to the compound providing the body with increase pain suppression, and increased energy levels. It’s basically the miracle ingredient.

Red Beet

Red beet is a vegetable, and it may seem odd to see it on this list. However, red beets have been shown to have high levels of many vital vitamins and minerals that are a huge benefit to those working out.

These vitamins and minerals include: B vitamin, copper, magnesium, potassium, iron, and manganese. All of which provide you with a long list of benefits, both for working out, and your general health.

Red beets alone provide you with increased stamina, enhanced cognative ability, and help to detoxify your liver.


RhodiolaRosea is extracted from the Rhodiola plant, and is an interesting one on this list. Research isn’t conclusive yet, but it is believed that the extract provides you with a range of desirable benefits.

These include:

• Improved athletic performance
• Improved sexual function
• Reduced recovery time
• Improves heart health
• Lowers cholesterol levels

It should be noted that these results have not been studied long enough in humans to say for sure that these effects are real. However, many studies do point to a strong correlation between people who take it, and these effects taking place.


Acetyl-L-Carnitine is a naturally produced protein in the body that helps to utilize ingested calories in the body and turning them into energy. By ingesting more of this protein, you will be equipping your body with a higher reserve, allowing you to produce more energy naturally.

Coconut Water Powder

Coconut water powder is a dehydrated form of coconut water, and it may seem like a strange addition to the 4 Gauge formula. However, much like red beets, coconut water provides the body with a range of vital vitamins to help keep you healthy.

These include: Vitamin C, several important nutrients, and is a potent source of dietary fiber. This last one is important, as an uptick in your dietary fiber will assist in hunger suppression.

4 Gauge – Known Side-Effects?

When taking the supplement ourselves, or reading the endless list of testimonials online, you’ll find a common trend. Almost nobody, ourselves included, experience side-effects from using 4 Gauge over an extended period of time.

This comes with an important but attached with it. As all pre-workout supplements, especially ones packed with as many powerful ingredients as 4 Gauge, come with a risk of caffeine overdose.

For this reason, it is not recommended to take 4 Gauge if you are under the age of 18, pregnant or breastfeeding, or suffering a serious medical condition. If you have problems with your heart, then it is strongly recommended you do not take 4 Gauge.

If any of this concerns you, then make sure to consult your doctor before taking 4 Gauge. The symptoms of a stimulant overdose will be:

• An upset stomach
• Jitters
• Headaches
• Mood swings

If you experience any of these, see your doctor.

4 Gauge – Dosage

4 Gauge is a powder supplement. It is recommended that you mix two tablespoons of the supplement into water and drink it, roughly 15-30 minutes before your workout.

An incredibly important thing to mention is: Don’t take more of 4 Gauge hoping for better results. The formula is already potent enough, and you will undoubtedly suffer a stimulant overdose as a result of over doing it.
