Testosterone supplements increase muscle mass, decrease body fat, and improve physical performance, among other benefits.

That’s why they’re always part of my bodybuilding recommendations. Lately, TestoFuel has become the product I most often recommend.

I’ve spent many months researching and reading through hundreds of TestoFuel reviews, as well as testing it on myself.

Read on my full honest review on TestFuel to find out its benefits, ingredients, and how to use it.

What Is TestoFuel?

Product image for Testofuel

TestoFuel is an all-natural testosterone booster and muscle-building supplement made by Roar Ambition.

It uses scientifically proven and all-natural ingredients to increase testosterone production.

The male sex hormone is vital to your overall health and well-being, and if your levels drop too low, you can suffer some quite severe health issues in the long run.

From a sports and fitness perspective, TestoFuel aims to increase testosterone levels to help athletes perform better during physical activity, boost the creation of muscle mass, and reduce body fat.

How Does Testofuel Work and Is It Effective?

TestoFuel is effective and works by naturally improving testosterone levels, which further accelerates muscle growth and supplies the body with the missing elements it needs to make more of the hormone [1].

Based on six months of research, interaction with users online, progress monitoring with my clients who use it, and taking it myself regularly, I can say that TestoFuel is effective.

Within weeks of use, I noticed a boost in my sex drive. After over a month, my workout performance and muscle building improved. I finally saw some developments in my midsection, arms, and chest appearance.

If you have been struggling with muscle building and muscle growth despite working hard at the gym and eating well, it could be down to the low testosterone levels, which can be medically and naturally rectified.


TestoFuel Ingredients

Supplement Facts of Testofuel

We'll get to the details of the TestoFuel ingredients shortly, but I can give away at this stage that my dietician has confirmed that everything in this product is natural.

Let's move on to the list of all the ingredients.

D-Aspartic Acid

This critical amino acid plays an indirect role by triggering a part of your brain to regulate certain hormones that send a signal to your family jewels to increase natural testosterone production[2].

Several users were convinced to try out TestoFuel at first because of the studies they've seen about DAA. Indeed, many users have a massive increase in their free testosterone levels, improving their libido and overall mood.

Vitamin D3

Referred to as the "sunshine vitamin," vitamin D has many critical health benefits. But one area that is often understated is that scientific studies have shown that it helps increase total and free testosterone levels. (3)

The most recommended form of vitamin D supplementation is cholecalciferol or vitamin D3 since the body quickly absorbs it. And it's one of the common ingredients I see in the leading T-boosters available today.

Oyster Extract

It’s a well-known testosterone booster and aphrodisiac, not just an old-wives-tale. As one of the best natural sources of zinc, the oyster extract has been linked to an improved reproductive function in both men and women [4].

My dietician also mentioned that it contains vitamin D and magnesium, which can help boost testosterone production and enhance endurance during workouts.


Speaking of zinc, TestoFuel contains an added dose of it as there have been countless studies that prove its effectiveness in increasing the production of the three building blocks of free testosterone: Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), and Human Growth Hormone (HGH) [5].

Zinc, DAA, and vitamin D3 are widely-studied ingredients proven to increase testosterone levels. It explains the positive results many users got, from faster lean muscle mass growth to increased motivation to hit the gym.


In Asia, ginseng has been used as a love life enhancer for thousands of years. This natural herb also helps with overall hormonal balances that improve your overall mood and testosterone levels [6].


Yes, this herb called fenugreek originates in Greece, and studies have shown that it can block 5-alpha-reductase and aromatase, two enzymes that use testosterone to produce other hormones [7,8].

Fenugreek is a great testosterone booster and is an ingredient I see in many T-boosters. Many users saw improvements in sexual performance, energy levels, and overall mood based on online reviews.


You probably know that this is important for muscle contraction and relaxation during heavy and intense training periods[9]. The makers claim it’s added for the ability to increase testosterone levels, but I haven’t been able to confirm it.

Within the first few days of taking TestoFuel, l noticed some positive changes in terms of muscle recovery, which may have helped increase my strength during intense workout sessions.

Vitamin B6

Vitamin B6 is essential for your overall health, skin appearance, eyesight, and liver function.

But it also plays a role in balancing both male and female sex hormone binding globulin levels, making it effective against low testosterone. It enhances one's sex drive and keeps the hormonal balance in check.

Vitamin B6 is also an essential ingredient in ZMA (zinc magnesium aspartate) supplements targeted at bodybuilders, professional athletes, and fitness enthusiasts, so you’re sure that it can support your overall immune system.

Vitamin K2

You probably won’t hear much fanfare about vitamin K2 due to its subtle effects. However, it plays a role in overall testosterone release, essential for TestoFuel's impact on muscle mass growth.

It may also lower triglyceride levels with vitamin D, resulting in better and more efficient muscle building and growth[10].

7 Benefits From Consuming Testofuel

OK, we’ve clarified the natural ingredients, so it’s now time to look at what all this extra testosterone will do for you from an athletic point of view.

These are the main benefits claimed by the makers, and I used online reviews and interviews with people at my gym to see if I could confirm them. (4)

1. No Testosterone, No Muscle Growth

Many athletes focus solely on muscle-building supplements to increase growth hormone production. But when it comes to muscle building and muscle mass, the two work side by side.

I often ask clients who struggle to trigger any significant muscle growth to have their free testosterone levels checked. If they haven't been lying about their diet, then 9 times out of 10, this is one of the reasons they are struggling with low testosterone levels.

Many of my clients who tried TestoFuel for the first time saw visible muscle gains on their chest and arms within just a few weeks of using the product.

2. Feel More Energized

Testofuel Product Image

Muscle building is a direct effect of healthy testosterone levels. But it also results from the extra energy.

Increased strength and endurance are certainly known effects of testosterone; otherwise, some athletes wouldn’t be resorting to illegal drugs that aim to achieve the same.

After months of reading reviews and comments online, many users comment on the energy and power boost within a few minutes after taking TestoFuel.

3. Speed Up Recovery Times

While amino acids are vital, your body needs some extra signals to maximize muscle repair, and a healthy dose of testosterone on a high-intensity day will go a long way.

Most of my clients complain about DOMS lasting for days after an intense session. And this is one of the areas TestoFuel helps a lot. After a few weeks of using TestoFuel, they noticed that their recovery times were cut short because they have more testosterone levels, allowing them to train every day.

4. Improved Mood And Motivation

People often think that a high testosterone level makes men aggressive. And while in very large doses, that can be the case, a proper balance has been noted in studies to affect brain function positively.

Muscle gains and body fat loss will happen much more efficiently when you're more energetic and motivated during workouts.

5. Increased Libido

If you do decide to try out TestoFuel, you can look forward to some increased libido, like how many users had a more exciting and enjoyable sex life.

Sexual excitement is caused in part by a rise in testosterone, though other factors contribute. Testosterone levels rise and fall throughout the day. Some men notice they are more excitable when testosterone is high, which is usually in the mornings.

- Alan Carter, Clinical Pharmacist

6. Increased Metabolism

When T-levels drop, your body’s ability to regulate your metabolism decreases. Taking TestoFuel will help increase your testosterone levels and boost your metabolism, keeping fat at bay and improving your body composition.

Any Side Effects?

No, TestoFuel doesn’t have side effects as long as you don’t have any allergies or intolerances to the ingredients listed above.

One of the most important ones to remember is the oyster extract. If you have a problem with shellfish, this is probably one product to avoid any allergic reactions or side effects.

However, after going through hundreds of TestoFuel reviews, I could only find isolated references to some stomach upset. Usually, those were down to people taking the total daily dose in one go without food. (5)

So, overall, there are minimal TestoFuel side effects that you would encounter. It's possible because TestoFuel is a natural testosterone booster.

And I was right to believe that because my clients and I haven’t experienced any nasty side effects during months of using the product.

How to Take TestoFuel?

testofuel 2

Take 4 capsules of TestoFuel per day to gain more testosterone levels, spread out over your meals and snacks, as the manufacturer recommends. (7)

The capsules are easy to swallow, but I suggest not taking them without food, especially when you’re just starting.

It’s more likely that you will encounter stomach upset if you take them after fasting.

Customer Reviews

I found a mix of comments on Testofuel in online forums, but here are a few I found that were consistent with its claimed benefits.

Since he started taking it a month ago, he felt a significant improvement in his mental focus. The product also didn’t upset his stomach or cause other side effects. - Mike S. from California

Within four days of taking Testofuel, this customer felt more energetic and awake. His sleep also seemed to be less disrupted. - Matt H. from Minnesota 

He has felt more energetic, focused, and motivated since taking Testofuel. His stamina in the bedroom also improved. - Dax P. from Illinoi

How Long Does It Take For TestoFuel To Work?

According to the company, it takes 6 to 8 weeks for TestoFuel to work and get the best results.

However, I did find online reviews that mentioned they started noticing their TestoFuel bodybuilding results by the time they got to the end of the first bottle, which is about a month.

In my experience, it took more than a month to see some changes in how my abs, arms, and chest look.

Your diet and activity levels influence testosterone production, so I always ask my clients to keep a detailed journal. (10)

Where to Buy TestoFuel?

hand view of a person using card and pc

Buy TestoFuel on the official website. It's not available in stores, so if you see it on a shelf somewhere, I would be suspicious of whether it's real.

It's occasionally available on some reseller pages, but I would caution there as well.

How Much Does TestoFuel Cost?

TestoFuel costs $59 for a 1-month supply bottle of 120 capsules.

If you buy two bottles, they’ll throw in an extra bottle for $118, and if you buy 3 bottles, you’ll get two different bottles, all for only $177.

It’s competitively priced among other leading T-boosters in the market. And it gets even better.

Their latest offering is called the Ultimate 360 bundle, where you get 12 boxes of Testofuel for only $495.60.

Shipping and Returns

Testofuel can be shipped to most countries except the ones on this list.

Unlike other companies, they do not offer a monthly subscription for their products, so you won't be charged anything unless you order on their website.

Five months in, I decided to buy the free-shipping Ultimate 360 bundle.  I was surprised by the notification that it would arrive the following day.

The manufacturers also claim that if you place your order before 2 PM EST or 1 PM GMT, it will be sent out the same day, depending on your location.

You can also return any unwanted items but make sure it's unopened to receive a refund.

Testosterone Booster Alternatives


Testogen contains similar ingredients to TestoFuel like D-aspartic acid, zinc, magnesium, and vitamin D to boost your testosterone levels. Still, it has added boron, piperine, and nettle leaf extract to provide the energy, focus, and motivation you need to get the most out of your workouts.

It costs almost the same as TestoFuel, but it’s 100% vegan-friendly, so that’s a plus for our vegan friends looking to fight low testosterone levels.

Aphro D

With only 4 herbal ingredients, Aphro D is one of the best performing all-natural testosterone supplements created by Dr. Farhan.

It significantly boosts testosterone production, enhances physical performance, and increases libido using only Tongkat Ali, Pearl Powder, Schisandra Berry, and He Shou Wu.

The main downsides with Aphro D are using a proprietary blend and the lack of different vitamins and minerals that can support the immune system.


Is Testofuel Safe to Take?

Yes, TestoFuel is safe to take as long as you don’t have any allergies to the ingredients. The only instances where I saw some adverse reactions were down to taking the total dose in one go, so make sure you stick with the recommended intake.

What Is Average Testosterone Level by Age?

The average testosterone level by age is 640 ng/dL for the 25 to 45 age range, 560 ng/dL for the 45 to 65 age range, and will gradually decrease to below 400 ng/dL for men over 80. These averages are influenced by diet and exercise, and other medical conditions.

Are Testosterone Boosters Illegal?

No, products that boost testosterone levels are not Illegal, as long as they contain natural ingredients and no medically controlled substances. Most people think of the steroids that professional athletes commonly use, but natural testosterone boosters are entirely legal.

Is Testofuel Approved by the FDA?

TestoFuel is not approved by the FDA, as the agency doesn’t approve testosterone supplements and other similar products. However, it's as good as FDA-approved because it’s made in FDA and cGMP-certified facilities in the US, includes clinically-backed doses, uses only extracts and natural ingredients, and fully discloses its ingredient profile.

Is TestoFuel Vegan?

No, TestoFuel isn’t vegan. The product contains oyster extract and uses gelatin in its capsules, which are non-vegan.

Is Testofuel Safe for Women?

Yes, Testofuel is safe for women. Although the supplement is primarily designed to boost testosterone levels for men, women can also benefit from it. With optimized T-levels, women can enjoy the following: better workouts, more lean muscle, increased fat burning, weight loss, improved energy, regulated menstrual cycles, and increased sex drive.

Should You Buy TestoFuel?

You should buy TestoFuel. It boosted my libido, improved my exercise performance, and helped develop lean muscle mass in my midsection, arms, and chest. Many of my clients who used it reported experiencing similar results.

And since Testofuel is an all-natural testosterone boosting supplement, we haven’t had any unpleasant effects.

Take advantage of the reasonable offers and money-back guarantee to see for yourself.
