4 Gauge Review: Still My Favourite Pre-Workout Supplement?

Will 4-Gauge pre-workout boost energy, increase muscle pumps, reduce fatigue, and improve recovery time? Read our 4-Gauge review to find out.

Are you struggling to get the most out of your workouts? Are your gains nowhere to be seen?

It sounds like you need a pre-workout supplement to help with blood flow, muscle pumps, focus, and endurance. However, the market is saturated with pre-workouts all claiming to do the same thing.

We are untangling the options today by focusing on one promising product, 4-Gauge by Roar Ambition.

Our 4 Gauge review covers the ingredients, side-effects, benefits, results, customer experiences, pros, and cons of this highly recommended pre-workout.

Is 4-Gauge your solution for the best workouts of your life? Let’s see.

What is 4 Gauge?

4-Gauge is an over-the-counter pre-workout supplement designed to help your mind and body “switch on” during exercise.

It is intended to help with mind-muscle connection, muscle pumps (that satisfying swell you see during strength training), and mental focus.

By boosting oxygen flow to the muscles, you have more energy to do more sets, lift heavier weights, and make each rep count.

4-Gauge comes in powder form and requires water to create a drink to knock back before a workout. 

About the brand

roar ambition

Roar Ambition is a UK-based company that makes pre-workouts, nootropics, testosterone-boosters, and fat-burners such as Instant Knockout and Testofuel.

We didn’t uncover any nasty secrets or signs of scamming, so we’re giving Roar Ambition two thumbs up for now.

Ingredients

4 gauge label

4-Gauge has a reasonably modest ingredients list, with 8 key ingredients.

We were happy to see that each ingredient is listed alongside the amount, unlike a shady proprietary blend.

You know exactly what you are taking, so you can run the ingredients past your doctor to ensure safety.

L-Citrulline DL-Malate 6000mg
An amino acid that increases nitric oxide (NO). NO is responsible for dilating your blood vessels so more blood and oxygen can flow through, leading to super-pumped muscles.
Creatine monohydrate 1000mg
Boosts energy levels for more stamina and strength during exercise. Increases muscle fiber creation for bigger gains, and boosts mental energy for more streamlined focus and motivation during hard workouts.
Acetyl L-Carnitine 500mg
An amino acid that boosts mental performance, increases oxygen supply to the muscles (resulting in more energy and power), stalls fatigue (by increasing NO levels), and helps with muscle recovery and DOMS (delayed onset muscle soreness). 
Red beetroot extract 300mg
Boosts NO levels, diluting cells so more blood and oxygen can be delivered to the muscles. This boosts energy levels and improves stamina for longer, stronger workouts.
Coconut water extract 300mg
Boosts hydration and electrolyte levels for reduced fatigue and better stamina during exercise. The potassium in coconut also helps with muscle aches and soreness post-workout.
L-theanine 200mg
An amino acid that provides focus and mental energy without a high-low crash and jitters. 
Caffeine anhydrous 150mg
Boosts fat-burning, increases energy and vitality, and may even improve muscle contractions for better, bigger gains.
Rhodiola Rosea powder 100mg
Reduces stress, boosts mood, reduces fatigue, and keeps you feeling motivated and happy to work out.
Other ingredients
Dextrose, erythritol, natural flavor, xylitol, monk fruit extract, silica, Swerve.

How does 4 Gauge Work?

4- gauge supplements

4-Gauge works in two key ways:

  • L-Citrulline and Acetyl L-Carnitine increase NO supply, improving cell dilation. This allows more red blood cells and oxygen to enter the muscles for more energy and better pumps.
  • L-Theanine and caffeine are added together to create a balanced and crash-free boost. Caffeine alone gives you that “pep” of alertness, but it can lead to scattered focus and a subsequent crash. L-Theanine offers mental focus but it also helps to reduce stress and induce a sense of calm concentration. The alertness of caffeine with the composed concentration of L-theanine helps with focused, enduring workouts.
  • The mood-boosting, fatigue-busting properties of Rhodiola Rosea and various amino acids help to prevent energy slumps. What’s more, they keep you feeling motivated and positive when it comes to exercise. You don’t get the gains if you’re having to drag yourself to the gym reluctantly.

4 Gauge Benefits

  • Dissolves easily
  • Simple to take
  • Boosts mood
  • Busts fatigue
  • Provides steady and crash-free energy and focus
  • Increases NO levels for improved oxygen supply

Real User Reviews

4 gauge muscle building

Customer response to 4-Gauge is great across the board.

While some find the flavor to be lackluster, most customers found it stayed true to its claims.

Plus, we didn’t find any reports of side-effects.

Many found that 4-Gauge boosts energy levels without unpleasant jitters or crashing. For example:

 

Tried numerous pre-workouts and this one is the best in my opinion. Gets a good buzzing going straight away and lasts for the duration of the workout. Flavour isn’t all that good but I mix with flavoured creatine which negates that. Price is worth it IMO, highly recommended for serious lifters.

About 20 minutes after drinking two scoops, I feel very focused and energized due to the “smart caffeine” blend of caffeine and L-Theanine. On top of the focus, I also feel skin-splitting pumps during every workout.

4 Gauge really helped get me in the gym when I’d usually be going for a nap in between Uni. I didn’t feel any energy crashes or jitters you might experience with other pre workouts. This was great for me because I had to attend rugby training and lectures at uni after my gym sessions.

4 Gauge doesn’t give you that strange tingling sensation that other lower quality pre workouts do which is the last thing you need during a training session.

How Do I Take 4 Gauge?

Combine 2 scoops with water and drink 15-45 minutes before a workout. The wait time differs from person to person, as some may find the effects to take a little longer to kick in.

4-Gauge states that you can increase your dosage to 2 serving sizes combined (equal to 4 scoops) if you need a bigger boost. However, try the single serving first (2 scoops).

4-Gauge recommends taking 1 week off from 4-Gauge after 6-8 weeks of usage. This is to ensure that your body doesn’t simply get used to the ingredients and stop responding.

A note on flavor: most people find the 4-Gauge flavor (there is only 1) to be pleasant enough. Some reported a slightly synthetic taste, but overall, it’s not bad.

Price And Where To Buy It?

The best place to purchase 4-Gauge is directly from the website 4gauge.com, as you can reap the benefits of:

Returns Policy And Money-Back Guarantee

As far as we can tell, 4-Gauge isn’t backed by a money-back guarantee. The website states that you can return any “unopened or unwanted items”, but there is no information regarding the refund terms. If you simply don’t like the product? There’s nothing you can do.

Is 4 Gauge A Scam?

Side Effects: Is 4 Gauge Safe For Everyone?

4-Gauge is a low-risk supplement as the ingredients are considered generally safe, and are used in safe amounts.

However, no supplement is completely out of the woods when it comes to potential side effects.

Plus, 4-Gauge contains caffeine, which can be totally harmless for some, but disruptive for others. Caffeine-related side effects may include:

  • Jitters and anxiety
  • Sleeplessness and insomnia

Check with your doctor before taking 4-Gauge, especially if you:

  • Are pregnant or breastfeeding
  • Are under 18
  • Are taking regular medications
  • Are intolerant to caffeine
  • Have a history of kidney issues (4-Gauge contains creatine which can pose issues with kidneys)

When it comes to real customer reviews, side-effects are almost nowhere to be found. Most people were pleased that they didn’t get tingling or jittery sensations associated with other pre-workouts.

However, everyone is different, so be safe over sorry by checking with your doctor first and don’t exceed the recommended dosage.
