4 Gauge vs Optimum Nutrition Gold Standard Pre Workout

A battle between two big sellers today. Our 4 Gauge vs Optimum Nutrition Gold Standard Pre Workout review will surely reveal one of the best products on the market?

We have seen a fair few pre-workouts come out recently, but they all seem to be very similar. One thing they do seem to share is the fact that they can all cause side effects.

Can both products today ensure your safety?

That is just one element that we will be looking at. A good pre-workout needs to give us the following in order to impress:

  • Increased energy
  • Enhanced focus
  • Greater muscle pumps
  • Big gains!

Anything less than this and neither product will be recommended.

Let’s start by getting to know them a little.

4 Gauge vs Optimum Nutrition Gold Standard Pre Workout: Who Makes Them

Roar Ambition4 Gauge Pre Workout Supplement

The company behind 4 Gauge is this UK based company.

They do everything by the book. With FDA and GMP approved facilities and practices they ship directly from both the UK and USA.

Roar Ambition review and amend their ingredient profiles regularly. This ensures the customers are getting the best possible version at all times.

Also, their products come with generous money back guarantees. This makes your purchase risk free, as it should be!

If you are into endorsements then you will be impressed by theirs. UFC fighter Diego Sanchez puts his name to their fat burner, Instant Knockout. Also, former Mr. Universe Robby Robinson puts his name to their T booster TestoFuel.

Optimum NutritionOptimum Nutrition Gold Standard Pre Workout

Another UK based company here.

They are one of the really big names in the industry and make some of the best sellers in different niches.

They say that this product has been tested to be free of banned substances. The Gold standard version does seem to just refer them to the flavors though. Optimum Nutrition claims that these are enhanced to make sure they are better than the competition in this way.

The label does advise that it contains both natural and artificial flavors which is a shame to see. They have been part of the industry for over 30 years so you would expect a great product – that’s plenty of time to get it right!

Optimum Nutrition uses GMP certified facilities but although we found several reassurances on their about us page regarding quality, we couldn’t see any money back guarantee.

4 Gauge vs Optimum Nutrition Gold Standard Pre Workout Ingredients

This is where we can really set these two apart.

The early signs are positive for both. Neither product uses proprietary blends. This means we get to see all the dosages and in turn, can tell if the products will work or not.

Mutual Ingredients


A good start for both and a common ingredient.

It has so many uses, firstly, it can improve blood flow to the muscles. It manages this by increasing nitric oxide levels. Derived from the likes of watermelon, L-Citrulline is an amino acid that converts into Arginine in the body.

This helps with creatine synthesis. This is good as both products already give you Creatine, this makes sure there’s even more.

The 6,000 mg in 4 Gauge is a big amount that will be really effective. At 750 mg, Optimum Nutrition is giving you a lot less.

Creatine Monohydrate

The great start continues.

Examine.com tells us that it is often used by athletes to increase power output and lean mass.

It is a well proven and safe ingredient. In terms of pre-workout supplements, it is very much a mainstay ingredient. It benefits performance, and also the muscles. Creatine gives added strength and ensures they still have energy after training.

It aids recovery and makes sure you have a better chance of achieving even greater gains.

There is one study that shows that it can benefit the body at any time. This talks about how supplementing Creatine during arm flexor strength training led to greater increases in arm flexor muscle strength, upper arm muscle area, and fat-free mass than strength training alone.

The dosage in 4 Gauge is a very good and effective 1,000 mg. Optimum Nutrition has given their customers a big 3,400 mg. Both will do a great job of giving you the above.

Acetyl L-Carnitine

An ingredient that works in two ways.

It burns fat as well as increases energy levels. An ingredient that helps the consumer to train at a higher level for longer periods.

The 500 mg dosage from 4 Gauge is another big amount. The 375 mg in Optimum Nutrition will still be of use.


A popular ingredient for almost any supplement.

The energy increase is a good place to start. Caffeine helps the user to train harder, for longer.

The version in 4 Gauge is Caffeine Anhydrous. This is a powdered form that is easily absorbed by the body.

It also enhances focus and alertness, this is why it is often found in nootropic supplements as well. The 150 mg in 4 Gage is a great mount that will be well tolerated. As will the 175 mg in Optimum Nutrition.

Individual Ingredients

4 Gauge

Red Beet

An ingredient that enhances blood flow.

Red Beet is another excellent ingredient because it increases plasma nitrate levels. As a result, you will get more stamina.

On top of this, the added blood flow means your muscle pumps will be enhanced – this also equates to better gains. You will be seeing the results of your graft because you can work harder and for longer periods.

The 300 mg from 4 Gauge is another brilliant dosage.

Coconut Water Powder

With the added output comes the need for hydration and Coconut water is one of the best ingredients for ensuring your body gets what it needs. Full of electrolytes, the 300 mg is another very good dosage.

Because a pre-workout usually means you can up the intensity and work rate, you need to stay hydrated even more than usual.


A clever inclusion, most pre-workouts include ingredients like this when they share space with stimulants.

It helps the user to stay in control whilst not affecting the benefits of using Caffeine. It keeps you calm. L-Theanine is found in Green Tea leaves and it even makes sure that Caffeine’s positive effects last longer.

The 200 mg in 4 Gauge is a good amount. Since their Caffeine content is quite sensible, this is all you need.

Rhodiola Rosea

This Scandinavian herb is known to keep spirits up. Also, it has been found to keep your mind sharp. By giving you focus, it is a great idea from 4 Gauge.

The gym is full of distractions, especially the ones on your phone. Anything that can counter this is a good idea.

At 100 mg, it is a useful amount.

Optimum Nutrition Gold Standard Pre Workout

Vitamin D

A great ingredient for certain supplements, we’re just not sure about pre workouts really.

It can increase T levels and even help to burn fat, but that’s not what we are looking for.


Basically, this is Vitamin B1 and it’s not exactly the most useful ingredient.

Examine.com describes it as having limited benefits when taken by a healthy subject and that deficiencies are not common.

B1 is only good to get more of for people who have high blood glucose. Some say that it is able to help regulate appetite but deficiencies only really occur in those who have a poor diet or who abuse alcohol.

At 2 mg you aren’t getting that much anyway.


A more common ingredient, this is Vitamin B3.

It uses carbs for energy, burning them off in the process. This is good for energy levels as well as getting shredded.

However, when the body takes in excess amounts, Niacin passes through your urine and Examine.com does advise that for B3 to be effective you need around a gram of it.

17 mg falls far below that.

Vitamin B6

A useful ingredient in that it can help the body to create energy.

Again, it turns glucose into fuel so increased energy is one of its credentials.

The 2 mg included isn’t very much though so consider this to be a bit of a top up.

Folic Acid

A decent ingredient although there are better options.

It is a common find in pregnancy supplements for those trying to conceive but in a pre-workout, it can help to produce nitric oxide. This is good as it can promote muscle mass.

Sometimes known as Vitamin B9.

Vitamin B12

More of the same once again.

B12 works in the same way as B6 – it aids energy metabolism.

Since we can’t create it naturally, supplementing it can be useful. This is especially the case for vegans and vegetarians as prominent sources are meat, fish, and dairy.

Pantothenic Acid

Here we have vitamin B5 which is water soluble but not the best of inclusions.

Examine.com advises that it is rare to be deficient and supplementing it does not appear to give you much of a boost.

This makes the dosage of 10 mg another waste.

Astragalus Extract

Examine.com discusses Astragalus and says that in terms of muscle protein synthesis and T, it is an unexplored ingredient.

Without the relevant studies to back it, it’s difficult to vouch for it. Most studies seem to be injected into the subject and oral consumption needs more evidence to back it.

It is thought to have benefits for your immune system but this isn’t what we are after anyway.


Sure, this is a common ingredient in pre-workouts, but we don’t like to see it.

Beta-Alanine has been shown to cause paresthesia. It is a tingling sensation of the skin but it does pass within a couple of hours (see WebMD).

It is another ingredient where there aren’t a lot of studies to back it up. Beta-Alanine has some links to fighting fatigue and increasing the body’s production of Carnosine. If this is true then it would result in longer peak levels of performance for your muscles.

The 1.5 g included is high enough to cause paresthesia.

N-Acetyl L-Tyrosine

A sensible inclusion as this product contains stimulants, as most pre-workouts do.

L-Tyrosine counterbalances the effects of stimulants. This means you can stay calm but reap the benefits. Also, it has been found to promote focus and reduce stress.

At 250 mg, it is a decent amount.

Grapefruit Bioflavonoids Complex

An ingredient that has been found to support blood circulation.

Citrus bioflavonoids are also linked to antioxidant protection. It is used by some for weight loss but these attributes aren’t exactly what we are after.

4 Gauge vs Optimum Nutrition Gold Standard Pre Workout Side Effects

The easy place to start is with 4 Gauge.

They include a whole host of effective pre-workout ingredients that are natural, proven and dosed sensibly but effectively.

Potentially, Optimum Nutrition Gold Standard Pre Workout side effects include paresthesia. This tingling sensation in the skin does pass but is a bit of an annoyance.
