Overview of 4 Gauge Pre-workout

Any firearm lovers in the house? Shotguns in particular? Anyone? If you are here, you will agree with me that there is nothing bigger or better than a 4 Gauge shell when it comes to shotguns. Well, there is a pre-workout formula in the market going by the name 4 Gauge, and these guys are making some pretty bold claims. In fact, it is already audacious of the manufacturers to call their product 4 gauge, (those are some darn big shoes to fill).

What everyone has been wondering (up to this review) is whether the 4 Gauge pre-workout supplement packs as much power as its namesake. Does it back up its claim to blow apart your previous workout experiences? Does it provide sufficient ammo to murder those weights? This comprehensive review provides a detailed account of everything regarding 4 Gauge. Afterward, you can decide whether to load up on some before facing those weights.

4 Gauge Manufacturer

A company known as Roar Ambition manufactures 4 gauge. These guys are no newcomers in the industry and are known for a variety of premium supplements. For instance, Roar Ambition is the company behind market-leading testosterone booster, Testo Fuel. They are also renowned for their renowned fat burner Instant Knockout, which is highly preferred by athletes in combat sports, among others.

Moreover, Roar Ambition has a reputation for manufacturing its products in FDA and GMP-approved facilities. This suffices to say that this company adheres to strict guidelines and the highest standards of quality and safety.

What are the benefits?

The following are some of the popular benefits of 4 Gauge as reported by most users and experts:

Incredible Muscle Pump

Apart from the motivation that comes from deep within, there’s a thrill that happens when your muscles are pumped, and you feel that extra gush of blood racing through your veins. Fortunately, using 4 Gauge will help you realize some skin-splitting muscle pumps that will leave you feeling and appearing bigger during training, giving your arms that thick and veiny look. With such pumps, you will be able to push through to the last two to three reps out.

Stamina Boost

If you’ve got the energy, you can put in the work. Essentially, stamina refers to staying power. It is the ability to put in the work over a prolonged duration. In the same way, 4 Gauge helps you train for longer, allowing you to be more productive during your workout. Eventually, it is the amount of work you put in when at the gym that determines the kind of gains you’ll acquire.

Improved Focus

Distractions can be your worst enemy when trying to get some work done at the gym. While a set of headphones and some hardcore motivational music may do the trick, sometimes they just don’t cut it. 4 Gauge users have reported experiencing laser-sharp focus to help them concentrate during their workout sessions. The potent formula will help you fade out the rest of the gym (and the rest of the world if you like) and give 110% dedication to pumping iron or whatever exercise you’re doing.

Strength Boost

4 Gauge pre-workout supplement will make you feel unstoppable when training. The formula is developed to help you forge a stronger connection between your brain and your body, helping you to push beyond your personal best. As a result, you will realize you can lift more, and eventually build more muscle and grow stronger.

4 Gauge Side Effects

Ok, now this is interesting. For a product claiming to offer all the benefits named above, 4 Gauge isn’t associated with any side effects. At least none that have been documented. However, a closer look at the product’s ingredient list will provide more insight into this context.


Caffeine Anhydrous (150 mg)

Caffeine helps with power, focus, and endless energy. It is for this same reason that a majority of the renowned pre-workout supplements are usually packed with caffeine, albeit at the expense of some undesirable effects.

You don’t need hundreds of grams of caffeine, and 4 Gauge contains only 150 milligrams of it. That is half what rival brands have in their product.

When you are working out, the body uses glycogen as a source of energy. When your glycogen reserves are emptied, your energy decreases. Caffeine slows down the depletion of glycogen by encouraging your body to utilize the fat reserves as fuel.

Moreover, caffeine also enhances the strength of muscle contractions, which allows you to exert more power over more extended periods.

L-Theanine (200 mg)

This is an amino acid mostly found in tea leaves. It helps to rejuvenate your r mind and help you stay focused during and after a long workout. Essentially, it gives you energy without draining you, relaxes you without making you drowsy and motivates you without causing the jagged edge. Put briefly, it focuses your energy without causing you to crash. 

Moreover, when caffeine and L-Theanine are combined, they work incredibly well. The nootropic community knows this combo as smart boosters.

Creatine Monohydrate (1000 mg)

You’ve probably come across Creatine in some of your fitness endeavors, haven’t you? Chances are you know the product as a muscle builder, which enhances performance and power. However, 4 Gauge uses Creatine in its formula for different purposes.

Here, it is used to enhance hydration, enhance cognition and reduce fatigue.

L-Citrulline Dl-Malate (6000 mg)

Citrulline Malate is an amino acid that is extracted from watermelons and is probably one of the most effective vasodilators in the industry. Simply put, the Citrulline Malate in Gauge 4 delivers kick-ass muscle pumps that not only make you look better but also feel better. 

Upon absorption, the kidney converts Citrulline Malate into L-Arginine, which enhances your body’s nitric oxide levels, which dilates the blood vessels, allowing more blood to rush through.

4 Gauge contains 6000 milligrams of Citrulline Malate (studies have shown that amount to be the optimum for the best results). Moreover, 6000 mg of Citrulline Malate before exercise can lead to an increase in the growth hormone of up to 66.8%.

Red Beet (Beta Vulgaris) (300 mg)

The beetroot in 4 Gauge helps to boost the levels of nitric oxide and also one’s performance. Research findings indicate that drinking beetroot juice can increase the amount of plasma nitrate in the body, thus contributing to an increase in the nitric oxide levels in your body.

As mentioned above, an increase in Nitric Oxide levels increases your pumps and gives your muscles more nutrients due to the increased blood flow.

Moreover, beetroot can increase your plasma nitrate by 52% which can boost your anaerobic performance by 4.2% (equivalent to running a mile in 6 minutes today and after beetroot, you do it in 5.4 minutes).

Rhodiola Rosea (100 mg)

This is a herb that is used both by the Chinese and Scandinavians in traditional medicine to enhance cognition and overall mood. Moreover, the herb also combats fatigue and depression.

Some days you wake up on the wrong foot and lack the motivation to hit the gym. However, Rhodiola Rosea will enhance your mood, and promote that positive attitude necessary for you to work out and better yourself

Acetyl-L-Carnitine (500 mg)

Acetyl-L-Carnitine has a broad scope of benefits; it is no doubt it was included in 4 Gauge. First, it helps to combat fatigue. Secondly, it helps you feel invigorated, both physically and mentally. Thirdly, it reduces muscle damage, which is great after an intense workout. 

With a dose of 500 mg of Acetyl-L-Carnitine in 4 Gauge, you are getting the perfect amount for maximum results.

Coconut Water Powder (300 mg)

Coconut water has a plethora of health benefits, but let’s focus on how it will boost your performance in the gym. This constituent is rife with electrolytes, which helps you stay hydrated during an intense workout session. When you think about it, drinking coconut water is like sipping on a sports drink.

Secondly, coconut water helps to regulate blood pressure (lower) and also prevent headaches and hypertension.

4 Gauge Price

Do not be hoaxed. The authentic 4 Gauge pre-workout formula is only available for sale on their website. The price for a single shell of 4 Gauge is approximately US $45. Don’t worry. You can still purchase in your local currency (€, £ and AUD$). However, you may come across various offers and promotions that will give you a more BANG for your dollar.

4 Gauge Dosage

Similar to a majority of pre-workout supplements, 4 Gauge is available in powder form. The recommended way to mix it is two scoops mixed with approximately 10 to 12 Oz of water.

You are advised to take it approximately 20 minutes before you start working out.


So, what’s your take on Roar Ambition’s 4 Gauge shell? Do you think it packs the power you are looking for? What’d you make of the ingredient list and their respective dosages? Anyway, while the price of 4 Gauge may appear to be on the higher side, it may be justified; consider the extraordinary energy matrix, enhanced performance, incredible pumps. Moreover, it does not feature any proprietary blends and features a not-so-bad taste (taste is subjective). Overall, it’s all up to you, but if the price doesn’t intimidate you, then there’s nothing else holding you back. Load up your guns and take that shot with a 4 Gauge shell.
