Welcome to my TestoFuel review, where I’ll go into everything you need to know about this testosterone enhancing supplement. 

There are many different so-called testosterone boosters out there. Many men are interested in them due to the potential benefits for libido, strength, muscle, and other manly traits. 

After all, testosterone is largely what makes a man, a man. 

However, just because a product claims to work, doesn’t mean that it actually will! 

As a holistic health practitioner and health researcher, I’m always on the lookout to see what exactly is in these products and if they are safe and effective. 

In this review, I’ll go over TestoFuel’s ingredients and all aspects of this product to determine if it works, any benefits you’ll get, and whether men should actually buy it. 

Let’s begin.

About TestoFuel

TestoFuel was released by a company called Roar Ambition. Roar Ambition makes many other health supplements such as Hunter Burn, Prime Male, and Instant Knockout. 

Just like all of their brands, TestoFuel is designed to be top-notch quality, safety, and effectiveness. 

What is TestoFuel?

TestoFuel reviews

TestoFuel claims to be a revolutionary testosterone supplement that helps you pack on more muscle. 

Roar Ambition states that TestoFuel testosterone booster contains well-researched ingredients that provide your body with the critical nutrients it needs to boost testosterone and aid peak performance. 

Unlike steroids, TestoFuel is made to increase your testosterone levels in a safe, natural way so you can get all of the benefits without the risks. 

Is TestoFuel safe to take?

You may be concerned if testosterone boosters are safe to take. Messing with hormones is serious business.

But overall, TestoFuel seems safe to take for most people because it doesn’t actually contain any steroids or other hormone-based ingredients. 

Rather, TestoFuel only has vitamins, minerals, and herbal compounds that are generally recognized as safe.

Things to Consider Before Buying TestoFuel

In addition to the safety aspects mentioned above, there are a few other things to consider before buying TestoFuel. 


Most testosterone boosters aren’t very cheap, and TestoFuel is no different. The regular price costs over two dollars per serving. 

However, you do have some options to save by buying in bulk, which I’ll detail in a later section. 

Number of Pills

The serving size of TestoFuel is four capsules, so you do have to take quite a few each day. This may be a turn-off for some people. 


TestoFuel review

As mentioned, TestoFuel’s formulation is a mixture of vitamins, minerals, and herbs that allegedly naturally boost testosterone.

If you’re looking for a more hardcore supplement, such as an actual steroid or hormone-based supplement, this is not for you. 

It’s geared toward people who want a testosterone-boosting alternative to taking external hormones. 

TestoFuel Features

Here are some of the top features of TestoFuel. Check them out to see what TestoFuel may offer you. 

Natural T-Boosting Ingredients

You may be concerned when taking a testosterone booster due to the potential for unwanted side effects. 

After all, this is a very real issue, especially for steroids, selective androgen receptor modulators (SARMs), and other hormone-related products. 

These ingredients, particularly anabolic steroids, may cause issues ranging from acne and decreased testicular function to heart problems and liver damage.

But TestoFuel’s ingredients include things such as vitamin K2, boron, ginseng, and oyster extract. These may naturally enhance libido, strength, confidence, energy, and more. 

Therefore, you don’t have to worry about the side effects reported from taking exogenous hormones. 

Science-Backed Formula

No matter how bold a product’s claims are, if they aren’t well-researched, you’re unlikely to get any benefits. 

TestoFuel claims to have only the best ingredients backed by the latest research and clinical studies. 

And all of their ingredients are advertised to be at optimal dosages, which would give you the most effective results for testosterone, muscle, strength, and so on. 

We’ll see if that’s really the case when I break the ingredients down in a minute.

Muscle Growth and Strength Boosters

TestoFuel testosterone booster features

Low testosterone could be one of the reasons you’re not packing on size and strength like you used to. After all, 7% of men in their 50s have it, and this number increases with age. 

Even if you’re not clinically deficient, testosterone naturally declines as men age. This is enhanced by lifestyle factors that can lower testosterone, such as environmental toxins, poor sleep, stress, and an unhealthy diet. 

Fortunately, TestoFuel claims to use only the best, natural ingredients to boost your testosterone to new heights. 

And this, they say, is the missing link that will help you achieve higher levels of strength, muscle growth, and even better recovery. 

30-Day Money-Back Guarantee

You don’t want to spend your hard-earned money on something that ends up being a waste. How many other supplements are currently gathering dust in your cupboard?

Luckily, TestoFuel offers a 30-Day Money-Back guarantee if you’re not satisfied. 

Thirty days gives you a pretty good amount of time to try it out and see if it works for you. And if not, well, nothing lost! 

Free Shipping

Increasingly, high shipping costs are a major factor in whether or not a product is worth buying. 

TestoFuel seems to understand this, offering free shipping. They offer free shipping to the US and UK if you buy one or two bottles at a time. And they offer worldwide shipping to anyone who buys three bottles at a time. 

Does TestoFuel really work?

It is likely that TestoFuel will work as a testosterone booster.

Of course, individual results will vary, and some people may experience more benefits than others. 

However, TestoFuel contains many vitamins, minerals, herbs, and amino acids that have the potential to naturally increase testosterone levels. 

This is especially true for older men and people with low testosterone, whereas people with already high T may not see as many benefits. 

And there are many positive TestoFuel reviews on their website and Amazon too, some of which I’ll share a little later.

TestoFuel Ingredients

Next up in my TestoFuel review, I’m going to go over all of the active ingredients. Keep an eye out for what these ingredients may do and if they’re actually proven to work. 

Here are the main active ingredients: 

  • Oyster Extract
  • D-Aspartic Acid
  • Fenugreek Seed Extract
  • Maca Root Extract
  • Magnesium
  • Zinc
  • Boron
  • Asian Red Panax Ginseng Extract
  • Vitamin D3
  • Vitamin K2 (MK4)

Oyster Extract (100mg)

TestoFuel ingredients

One of the more unique ingredients in TestoFuel is oyster extract. Oysters are rich in several key nutrients such as zinc, vitamin B12, and selenium.  

The high concentration of zinc, in particular, is thought to help increase testosterone levels. 

And while one study found that oyster extract supplementation improved reproductive function in mice, no specific research on oyster extract supplementation has been done on humans. 

Effective dosage: N/A

D-Aspartic Acid (2,000mg)

D-aspartic acid (DAA) is an amino acid compound. It acts in the brain to release hormones that eventually lead to enhanced testosterone production. 

Some research shows that DAA supplementation can enhance testosterone levels in infertile men and athletes, but it’s somewhat inconsistent.

Effective dosage according to Examine: 2,000 to 3,000mg

Fenugreek Seed Extract (50mg) Equivalent to 800mg Fenugreek Seed Powder

TestoFuel testosterone booster ingredients

Fenugreek is a medicinal herb known for its libido-enhancing and testosterone-boosting properties. 

Various compounds in fenugreek (such as saponins) may act as testosterone-enhancers. Fenugreek also seems to inhibit enzymes that convert testosterone into estrogen, which would mean more bioavailable testosterone. 

Overall, fenugreek supplementation seems to increase testosterone levels in men. Other research shows that fenugreek may enhance body composition, libido, and strength. 

Effective dosage based on available data: 500 to 600 mg

Maca Root Extract (180mg) Equivalent to 1,800mg Maca Root Powder

fuel testosterone booster ingredients

Maca has a long history of use as an aphrodisiac (libido-enhancer). Maca contains anti-inflammatory compounds that may decrease inflammation. This can lower inflammation in the testes, which may support sexual function.

There is some evidence that maca can boost libido and sexual function, although there aren’t many studies.

Effective dosage according to research: 1,500 to 3,000mg

Magnesium (70mg)

Magnesium is a critical mineral needed for hundreds of reactions in the body. It supports heart, brain, muscle, and metabolic health, among other things. 

Also, magnesium is necessary for optimal testosterone production, including free testosterone. Supplementing may increase testosterone while also boosting strength and muscle function, so it’s particularly helpful for athletes

Effective dosage: 250 to 450mg

Zinc (10mg)

Another key mineral included in TestoFuel is zinc, in the form of zinc monomethionine aspartate. 

Zinc plays key roles in inflammation, immune health, and of course, hormonal health and testosterone. 

A zinc deficiency is related to low testosterone levels in men, but fortunately, zinc supplementation may increase testosterone in men with low T. 

And zinc supplementation can increase testosterone levels in weightlifters

Effective dosage according to research: Either 5 to 10mg (preventative) or 25 to 45mg (for people with a deficiency)

Boron (8mg)

The last mineral here is boron, in the form of boron chelate. 

Boron has a number of roles in the body, such as immune function, inflammation control, nutrient absorption, and hormonal health. 

Some research shows that boron supplementation increases free and total testosterone while also decreasing estrogen. 

Plus, boron can help increase the effects of vitamin D and magnesium, which could help increase testosterone, too. 

Effective dosage: 6 to 10mg

Asian Red Panax Ginseng Extract (100mg)

reviews on TestoFuel

Panax ginseng is known as the “true” form of ginseng and has been used to enhance energy, stamina, libido, and fertility. 

It contains some bioactive compounds that are believed to increase fertility and testosterone, although most of the research doesn’t show any major benefits. 

Still, ginseng might increase libido in men. 

Effective dosage based on data: 3,000mg

Vitamin D3 (4,000 IU)

Vitamin D3 is the most bioavailable form of vitamin D, so it is the best form to use as a supplement. 

In general, low vitamin D levels are associated with lower testosterone levels in men. Vitamin D is also important for bone and muscle health and immune function. 

While some studies show that vitamin D supplementation can increase testosterone levels, most research has found little to no direct benefit. 

But it may help if you are deficient in vitamin D. 

Effective dosage (to correct a deficiency): 1,000 to 2,000 IU. Potentially higher in some cases.

Vitamin K2 (18mcg)

The last ingredient in TestoFuel is vitamin K2, in the form of menaquinone-4 (MK4). 

Vitamin K2 is necessary for bone and heart health. Taking it with vitamin D3 (listed above) may be beneficial since they often act in synergy with each other. 

However, in terms of testosterone, there really isn’t any research showing any benefits besides a few rat studies like this one.

Effective dosage (for general purposes): At least 1,500mcg

TestoFuel Pros and Cons

To review what we’ve learned, I’m going to go over some of the key pros and cons of this testosterone booster. 

Take a look at the list below to see some of the main benefits and drawbacks of TestoFuel. 


  • Well-researched ingredients
  • Effective doses of maca, DAA, and fenugreek
  • Vitamins and minerals for T support
  • Worldwide shipping
  • May increase strength and muscle
  • Ingredients for energy and libido


  • A few ingredients underdosed (e.g. ginseng, magnesium)
  • Pretty expensive
  • Some ingredients don’t have direct benefits (e.g. vitamin k2)

How to Use TestoFuel

For maximum effects, TestoFuel recommends that you take TestoFuel testosterone booster every day for at least two months. 

You can take it any time of the day, but it typically helps to take it at the same time every day to get into a habit. 

Recommended Dosage

TestoFuel testosterone booster dosage

The recommended dosage is four capsules per day. You can take it with or without food. However, it may be better to take it with food to reduce the chance of gastrointestinal symptoms. 

Real Customer TestoFuel Reviews

Let’s see what actual customers are saying. 

In general, most of the reviews are positive. They have a four out of five rating on Amazon and a lot of positive reviews on the main website, including some pretty impressive TestoFuel before and after transformations. 

However, those should be taken with a grain of salt since they were chosen specifically for the official website.

TestoFuel Real Reviews:

“Do not expect to take this and see results in a few weeks. This product works best when combined with healthy diets, moderate activity, and quality sleep. If you are looking for the miracle pill, it doesn’t exist, but this product does assist in increasing testosterone levels over time if they are lower.” -Christian S. 

I am a 42 year old who goes swimming and the gym on a daily basis. I have been taking out these capsules for a week now and I can certainly feel the difference. I can feel a lot more strength in me leading to a better performance both at the gym and swimming pool.” -Javier S.

“The shipping was fast and the packaging was nice. When I first started taking TestoFuel I didn’t notice a big difference until around week three, but then it seemed to really kick in and I was getting bigger and stronger every week following.” -Brenon B

“I started to feel the supplement working within two weeks of using it. I felt more energetic, physically and mentally stronger while doing my training.  I can lift more than I ever imagined myself doing, and my body’s finally looking good. On top of all that, the confidence boost I get from TestoFuel is wonderful.” – Cyrus S. 

“I’ve been using these for close to a month now and I can honestly say I haven’t really noticed much difference. It’s difficult with things like this because they’re not exactly night or day pills – they’re not steroids. The effect that they have is likely to be very subtle so it’s difficult to notice any changes. That doesn’t mean they don’t do anything, it’s just hard to notice.” -Daz 

TestoFuel vs. Testogen

Many people are also interested in the differences between TestoFuel and Testogen, another very common testosterone booster. 

TestoFuel and Testogen have many similar ingredients, such as fenugreek, DAA, magnesium, Asian ginseng, vitamin D3, zinc, and boron. 

However, some differences are that TestoFuel has maca and oyster extract, whereas Testogen has nettle leaf and vitamin B6. 

Also, regarding dosages for some key ingredients, Testogen is higher in DAA, magnesium, and ginseng, but TestoFuel is higher in vitamin D and fenugreek. 

Both have the same amount of zinc and boron. 

Lastly, Testogen is a little cheaper, but only by a few dollars, so this really isn’t a defining factor either. 

Overall, there isn’t enough of a difference between TestoFuel and Testogen to say that one is significantly better than the other. 

Alternatives to TestoFuel

Given that most TestoFuel reviews are positive and it seems like a solid supplement, you may wonder why I’m going to go over alternatives. 

The truth is that one particular supplement likely doesn’t work well for everybody. This is pointed out by some of the negative TestoFuel reviews. 

Below I’m suggesting a few different testosterone boosters that may work better for you based on their different ingredients, potential effects, or other aspects. 

Nugenix Total-T

Nugenix Total-T is one of the most popular testosterone boosters out there. It is designed to boost confidence, energy, and overall wellness for men. 


  • Well-researched ingredients
  • Supports workout performance
  • Solid dose of Fenugreek and boron
  • Free from fillers


  • Expensive
  • Some ingredients are underdosed (e.g. zinc, Eurycoma longifolia)

Try Nugenix Total-T here.

Prime Male

Prime Male is advertised as a testosterone and vitality enhancer. It is also made by the parent company Roar Ambition. 


  • Many clinically-researched ingredients
  • High dose of zinc and vitamin D
  • Ginseng, ashwagandha, and other key herbs
  • May boost physical and mental performance 


  • Very expensive
  • Have to take it four times per day
  • Some ingredients aren’t dosed very high (e.g. ginseng, magnesium)

Health Benefits of TestoFuel

A handful of health benefits may occur, such as:

  • Boosted Testosterone Levels
  • Enhanced Libido
  • Muscle Growth and Strength Increases
  • More Energy and Drive
  • Body Fat Reduction

Boosted Testosterone Levels

TestoFuel may boost testosterone levels due to a few different ways. It has a handful of ingredients that may help to directly increase free testosterone, decrease estrogen and cortisol, and support overall hormonal health. 

Likely the most effective ingredients for this are fenugreek, zinc, and boron, but there are others. 

Enhanced Libido

TestoFuel testosterone booster benefits

You may get an increase in libido and sex drive from TestoFuel. This is mainly based on the potential increase in testosterone, especially free testosterone. 

It is known that low testosterone is related to poor libido, so TestoFuel may help to restore sexual function, especially in men with low T. 

Muscle Growth and Strength Increases

Testosterone is also one of the major hormones involved in muscle growth, in part due to its effect on protein synthesis

So, TestoFuel may help you increase your muscle mass and improve strength by giving your body the testosterone boost it needs. 

This is especially true for people with lower testosterone levels, whereas men with already adequate levels may not see much of an increase here.

More Energy and Drive

TestoFuel real reviews

TestoFuel may also increase your energy and drive. This may be due to the Asian ginseng in particular, but the other ingredients may increase energy too indirectly by enhancing testosterone levels. 

Body Fat Reduction

In theory, TestoFuel might help you lose body fat and improve your body composition. 

Testosterone is a key hormone involved in body composition, so increased testosterone may mean lower body fat. 

Potential Side Effects of TestoFuel

The ingredients in TestoFuel are generally recognized as safe, but there are a few potential side effects. 

Fenugreek, maca, and some of the other ingredients in TestoFuel may cause diarrhea, nausea, and other digestive symptoms. 

These side effects were noted by some customers in their TestoFuel reviews.

More possible TestoFuel side effects include headache and dizziness, although these are rare. 

TestoFuel Price

Each bottle of TestoFuel contains 30 servings (120 capsules). 

The regular price, or what they call the Testosterone Starter Bottle, is $65 ($2.17/serving). You get free delivery in the US and UK.

You can also buy their Testosterone Support Pack, which is a two-month supply for $130 ($2.17/serving). 

The price is the same per serving, but you also get Boss Lean Mass for free, which is a nutrition and training program for body transformation. Delivery is free in the US and UK.

Lastly, you can buy the Ultimate Muscle Gainer’s Package, which includes three months of TestoFuel plus one month free for a total price of $195 ($1.63/serving). This option also includes the free Boss Lean Mass program. Free worldwide delivery is available.

Overall, this is a pretty expensive product, but it is nice that there are a couple of ways to save big. Most testosterone boosters typically cost over $1.50 anyway, so it isn’t much more expensive than others. 

TestoFuel Shipping & Returns

You get free shipping in the US and UK if you purchase one or two bottles at a time and free worldwide shipping if you order the three-month supply. 

Orders in the US and UK are generally delivered within one to 10 days, depending on the shipping option you choose and other factors. 

Orders in the rest of the world are generally delivered within two to 15 days, depending on shipping option and location, among other things.

They have a 30-day Return Policy for orders in the US and Canada, and a 14-day Return Policy for orders in the UK and the rest of the world. 

The product must be unused, unopened, and in its original form and packaging to be returned.

Final Recommendations

You’ve reached the end of my TestoFuel review. 

How frustrating is it to not be at your best, physically or mentally? 

Decreased libido, loss of muscle and strength, fatigue, and so on…these don’t have to be necessary parts of aging. 

There truly are ways to get back your mojo, muscle, and drive, or even enhance these in younger guys. 

Altogether, TestoFuel appears to be one of the better testosterone supplements out there. 

With several well-researched ingredients designed to boost testosterone levels, TestoFuel is a potentially great option for older men, athletes, and other people looking to get all the benefits from enhanced testosterone. 

So, if you’re interested in trying out TestoFuel click here. If you try it, leave me a comment telling me what you think.
