On my social media feed, 4 Gauge started appearing quite a while ago, but it’s only after my dietician mentioned it to me that I paid any attention.

The list of ingredients did look interesting, especially the unique combination.

So, I decided to try this pre-workout supplement and see if it lived up to the hype of increasing physical performance and providing more intense muscle pumps.

Online feedback looked good, and upon testing the product myself for several weeks, I was pleasantly surprised with my results.

But, let’s start this 4 Gauge review with the basics.

What Is 4 Gauge?

4 Gauge Pre Workout Supplement

4 Gauge is a pre-workout supplement that uses a unique formula of natural ingredients to help you enhance your athletic performance at the gym.

According to Roar Ambition, the company that makes it, you will be able to push yourself harder, look significantly bigger, and have the mental focus to stay motivated towards your fitness goals.

The company has produced the powder by taking advice from dietitians, nutrition experts, and top performance athletes and bodybuilders.

From my conversations with other bodybuilders and some nutrition experts, I believe that 4 Gauge pre-workout has managed to combine natural ingredients that work exceptionally well together.

I'll dive deeper into the natural ingredients shortly, but let's first look at the benefits of this pre workout supplement.

Suitable For Men & Women

4 Gauge Benefits - What to Expect

Many people I spoke to at my gym agreed that there is a significant enhancement in the pumps you can expect while using 4 Gauge pre workout supplements.

I noticed a good increase in energy levels, which improved my pumps and endurance.

Users often highlight that they can put in more effort than usual because endurance and energy levels will increase, consistent with what I experienced.

Many people also commented on the lack of jitters, common with other products that heavily rely on caffeine for its mental focus-boosting effect.

Through a clever combination of caffeine and L-Theanine, a mental improvement is achieved with a lower dose of caffeine.

I can be a little sensitive to caffeine, but as most users experienced, it provided an extra boost in focus and motivation during each session and even a few hours later.

The main benefits can be summarized as follows:

  • Increases muscle pumps for more effective workouts.
  • It helps improve mental performance for more focus and motivation.
  • Increases blood flow to deliver more oxygen, energy, and focus.
  • Increases stamina so you can train longer and harder.

Any Side Effects? Should You Be Worried?

4 Gauge pre-workout supplements have very few side effects, so you shouldn't be worried.

From some online chats, I did find a few people who had some food intolerances to some of the ingredients, e.g., coconut.

So before you hit the buy button, make sure you don’t have any known allergies to them to avoid similar side effects.

My personal experience with most pre-workout supplements points at artificial sweeteners and very high doses of caffeine as the causes of not-so-great effects.

But both of these are not present in this product, which is a real positive.

The only negative I was able to find in these pre workouts is that it’s only available in one flavor. It tastes sweet and slightly sour with an overall fruity flavor, which is quite pleasant to drink.

Cons:

  • Only available in one fruit punch flavor

What Are The Ingredients?

4gauge supp facts

4 Gauge pre workouts contain a combination of eight key ingredients that are proven to be effective. Here's everything you need to know about its formula.

1. Caffeine

4 Gauge pre-workout supplements take a slightly different approach and creates a "smart caffeine."

It contains 150 mg of caffeine anhydrous, which is about as much as caffeine from a 12-ounce cup of coffee.

But because this is combined with L-Theanine in the same product, you also get a mental calming effect that steadies your mind.

As one of the main ingredients of 4 Gauge, I did feel a significant boost in my energy, power, and focus during my training sessions.

2. L-Theanine

This is one of the clever ingredients on this list as it works so well together with caffeine.

It’s a combination that has become very popular in nootropics (brain boosters) for this very reason.

It works by boosting a neurotransmitter called GABA (gamma-aminobutyric acid if you fancy trying to pronounce it).

Essentially, it introduces more calmness to your brain activity, helping you to stay focused. (1)

On its own, L-theanine may improve a person's attention and reaction times. In combination with caffeine, it may lead to improvements in their number skills and alertness. Caffeine is a stimulant, so it can help people stay alert and focused.

3. Creatine Monohydrate

Creatine-Monohydrate

A study conducted in 2012.

Found a direct correlation between an athlete’s strength and stamina when regularly taking this pre-workout supplement before a workout session (2).

I have used it in isolation during bulking phases, and I record better results during training.

After getting the timing right, I gained around 1 to 2 lbs of lean muscle mass within just a month.

4. L-Citrulline DL Malate

Citrulline malate is an amino acid precursor to nitric oxide, and with 4 Gauge pre-workout supplements, you get 1 gram extracted from watermelons.

With your skeletal muscles pumping hard, they will need as much oxygen and nutrients as they can get.

And with widened blood vessels, blood can flow more easily to where it is needed most.

Nitric oxide acts as a vasodilator, which means that it relaxes the inner muscles of blood vessels (3). I did notice less fatigue and shorter recovery time after a tough workout during my first few days of using 4 Gauge.

5. Red Beet Root Extract

Beetroot has been known to have potent performance-enhancing effects, with a study from 2012 showing that the running performance over a 5 km distance improved in the last third (4).

This shows that it boosts endurance to help you perform better for longer.

With 4 Gauge pre-workout, you get 300 mg of red beet extract

6. Rhodiola Rosea

Rhodiola Rosea is a natural product that has been used as a traditional medicine in Scandinavia and Russia for a very long time.

It reportedly works by limiting your body’s resistance to physical stress and a lack of motivation.

In another study, students experienced significantly reduced mental fatigue, improved sleep patterns, and increased motivation to study after taking Rhodiola supplements for 20 days. Their exam scores were also 8% higher than those in the placebo group.

7. Acetyl-L-Carnitine

The main benefit of this difficult to pronounce amino acid is as a fat burner. (5)

Acetyl-L-Carnitine is an amino acid that transports fatty acids to cells that turn fat into energy.

The added benefit is that you get an energy boost simultaneously, which helps during tough workout sessions.

The more Acetyl-L-carnitine you have in your system, the easier it is for your body to burn off some fat, allowing you to build more muscle gains.

8. Coconut Water Powder

This is a good source of electrolytes and something I always preach to clients for pre-workouts rather than just post-workouts.

4 Gauge pre-workout provides 300 mg of dehydrated coconut water powder per serving, which will help you stay hydrated during training (6).

When Should You Take 4 Gauge?

man drinking 4 gauge

You should take 4 Gauge pre-workout about 30 minutes before you head to the gym.

If you have some extreme workout sessions planned, you might want to take it closer to starting. The makers suggest this, and my own experience seems to confirm it.

For extreme bodybuilding or very long training times, you do have the option to double dose. However, I suggest staggering your consumption rather than taking four scoops immediately.

One small recommendation I would add is that it’s always a good idea to have an off-cycle as well.

The creators recommend one week off every 6 to 8 weeks, which sounds very sensible to me.

Suitable For Men & Women

How Much Does 4 Gauge Cost?

Each bottle of 4 Gauge costs around $45, and it contains 20 servings. But if you want to save more money, go for the 3-shell package or the "Ultimate Ammo Crate" package.

It comes with free shipping, and aside from 3 shells, you get one free for a total price of $135.

This deal is available on their official website.

It's a pretty competitive price compared to some other pre-workout supplements available.

But with the results I got and my clients and users online, the price is highly reasonable for a vegan-friendly pre-workout.

4 Gauge Reviews - Real User Reports

I reached out to some Facebook groups to see what they had to say.
Here are some 4 Gauge pre-workout reviews I got from users.

4 Gauge user for 6 months, and it has become my go-to exercise supplement. It contains everything my body needs, and I can see a significant difference in performance when I forget to take it.
- Jason Sanchez, Florida

I’ve just finished my first batch and ordered the second, and even my personal trainer has told me how much I've improved. I can do more in each training session. The pumps have improved and I’ve been able to add extra sets in every training.
- Dustin Hurt, Ontario

Love that 4 Gauge has been delivering directly to the UK! It’s been on a constant resupply order at my gym. Pretty much everyone I know in the gym has switched to it because it avoids having to stack other pre-workouts.
- Tony Jones, Manchester, England

Overall, this product gets a perfect score for me, whatever rating you want to give it! Will definitely buy again. (4)

Pre-Workout Alternatives

Transparent Labs BULK

Transparent Labs BULK is a vegan-friendly pre-workout specifically formulated to support bulking.

It contains citrulline malate, beta-alanine, and BCAAs, providing the energy, strength, and endurance needed to support muscle growth.

Unlike 4 Gauge with just one flavor, it has seven flavors to choose from to satisfy your taste buds.

However, it’s a little bit more expensive than 4 Gauge.

Cellucor C4 Original

Cellucor C4 Original is one of the most versatile products in the C4 Pre-Workout range.

Aside from beta-alanine and arginine, it uses creatine and caffeine to provide advanced energy, endurance, focus, and pumps, similar to 4 Gauge.

A month’s supply is significantly cheaper than 4 Gauge, and it comes with a good selection of flavors.

FAQs

How long does 4 Gauge last for?

4 Gauge will last for about 2 to 3 hours in total. This does depend on your physical size and how hard you train, but that’s a good average to work with.

Does 4 Gauge need to be cycled?

No, 4 Gauge does not need to be cycled. But ideally, you can take a week off the pre-workout supplement after taking it straight for 6-8 weeks. This gives your body time to rest while still maximizing muscle gains.

Should You Buy 4 Gauge?

Drawing from my own experience and all the customer feedback and information presented in this 4Gauge review, this pre-workout really does work.

There are so many poor products out there when it comes to pre-workout supplementation.

I generally encourage people to ignore those heavily advertised products, but 4 Gauge pre-workout has been a pleasant surprise.

Based on all the research I’ve done, personal testing, and talking to my clients, this is a reliable pre-workout supplement that will bring you to an optimal performance level due to ingredients like Acetyl-L-Carnitine.

If you’ve been struggling with your muscle-building progress, then this will quite likely be your #1 solution.

Make sure you order yours today and then post a review on this site or our Facebook group.

Is This Pre-Workout Worth Buying?

  1. I’ve been using 4 gauge as my pre workout ever since I started going to the gym and I have not changed it since then. This review gave my favorite supplement justice! Good job!

  2. Is this product safe? I’m asking because I’ve taken supplements before that made my heart raced. I felt sick during my workouts. I never want to experience it again. Thanks for answering!

    1. I can totally relate, Kevin. We experience this side effect because supplements contain a certain amount of caffeine. No worries, though. 4 Gauge only has the right amount of caffeine– just enough to power through your workout. Hope this helps!

  3. Thanks for this review! I’m going to give this a try.
