TestoFuel – Testosterone Booster Review

You are currently viewing TestoFuel – Testosterone Booster Review

After hitting a certain age, men tend to start losing their testosterone levels. With further aging, they keep decreasing at a rate of at least 1 percent every year. When testosterone level drops enough to begin to affect health negatively, this condition is called hypogonadism or low testosterone (low T).

Patients can either try a solution of more natural ways to boost testosterone, including sports, balancing their diet, quitting smoking and alcohol, etc. It is a fool-proof method, as a healthier lifestyle never hurts, but it has its drawbacks. First, it demands great discipline and patience, as the organism requires time to readjust. Second, if T production had already dropped enough, the health decline can make it tricky to maintain even your daily tasks, not to mention increasing your physical activity and beginning to cook wholesome meals.

The second possible method is to start replacement therapy. It implies taking synthetic testosterone via injections, pills, topical gels, or patches. It provides a direct and quick effect, but exposes the patient to various risks, as well.

This explains the popularity of dietary supplements that supposedly can help you increase testosterone levels. They promise comparatively fast effect, improvement of your health in general, and fewer to no adverse reactions. Our TestoFuel review takes it as a test subject to help customers better understand this product and make an educated decision regarding purchasing it.

What is TestoFuel

TestoFuel is a natural so-called testosterone booster manufactured in the USA and UK by Roar Ambition. The manufacturer is mostly focused on supplement production and nutritional research for athletes, gym enthusiasts, and fitness fans.

The manufacturer states that its formula was extensively researched and is based on the latest scientific data to provide impressive results not just in rising the level of free testosterone, but also improving your general mental state and performance.

Who Should Use It?

TestoFuel is mostly promoted for men who experience the symptoms of TD, such as:

  • low energy;
  • difficulties losing weight and gaining muscle mass;
  • mood swings;
  • depressed state;
  • issues related to low libido, etc.

It is also promised to be beneficial for athletes and bodybuilders as a healthier and safer alternative to steroids which are often used to make muscle-building more fast and effective.

Nevertheless, women can suffer from low T also. Because the TestoFuel work is based on naturally-originated constituents that are able to stimulate the body’s own testosterone production, it should be good for everyone regardless of their sex.

How does TestoFuel Work

TestoFuel constituents are associated with testosterone metabolism in one way or other. It also contains micronutrients (e.g. vitamins and minerals) that should be a part of a healthy nutrition plan and play a significant role in the body. In combination, they are claimed to be able to boost testosterone levels, improve mood, raise energy levels, help you work out more efficiently, and become stronger and fitter.

Does TestoFuel Really Work?

There is no evidence-based confirmation of TestoFuel benefits as the supplement has never been clinically studied. And the research about its components being able to impact free testosterone levels varies from decent to limited or non-existent. The supplement itself is not an FDA-approved medication indicated to treat low T. This means that there is no guaranteed and scientifically proven effect of the supplement, and if you are determined to give testosterone boosters a try, keep in mind that it is a matter of luck (meaning your individual reaction to the product).

Increases levels of energy

With low T, is it a typical story to feel exhausted after daily work and struggle with additional activities and household chores. Restored energy gives you more stamina to keep up with your tasks while also maintaining a healthier lifestyle (cooking wholesome meals, taking walks, ditching harmful habits, exercising). The latter contributes to your testosterone levels as well, getting you on a spiral of wellness and self-improvement.

Metabolism Improves

Although estrogen is considered a female hormone, it is present and vital in the male body as well. However, with T levels dropping, estrogen levels tend to peak, causing many health problems and contributing to gaining stubborn abdominal fat and enlarged breasts.

TestoFuel is claimed to carefully balances those two hormones back improving your metabolism. Not only it helps you lose weight, but it also promotes muscle growth. Dreamt of building in the gym that boss lean mass? With testosterone closer to normal, it sure will be easier. It is, by the way, why the manufacturer recommends TestoFuel for bodybuilding.

Good Mood

TD makes your mental health lean toward depression. When boosting its levels, you feel more optimistic, cheerful, and motivated. Stronger confidence from better sex life and a better body also helps.

TestoFuel Ingredients

There are 10 main components in TestoFuel, all of them of natural origin. Every ingredient contributes its part to the declared effect of the supplement.

Vitamin D3 (as Cholecalciferol)

Cholecalciferol is a fat-soluble vitamin that had a huge impact on metabolic processes, the immune system, and reproductive function. And about 1 billion people globally have vitamin D deficiency that can cause, among other things, fast fatigue and depression—signs that are also common to low T.

There are also clinical studies that suggest that vitamin D has the potential to increase testosterone levels.

Vitamin K2 (as Menaquinone 7)

Vitamin K1 and K2 are mostly used in testosterone boosters for their ability to improve the absorption of vitamin D. The difference between them, is that K2 was found to have beneficial effects on serum levels of DHT (dihydrotestosterone, a more bioactive compound than original T).

Magnesium (as Magnesium Oxide)

For humans, magnesium is a macro mineral. It means it plays an enormous role in the body, taking part in everything from protein synthesis to brain functioning, and its deficiency can cause a vast variety of health issues starting from muscle cramps to depression. Studies show that magnesium increases total testosterone both in athletes and not physically active patients.

Zinc (as Zinc Aspartate)

Zinc is proven to be present in the Leydig cells where testosterone is being produced. Its supplementation has been proven to be effective in raising testosterone levels in zinc-deficient patients.

D-Aspartic Acid

DAA is an amino acid affecting the production of luteinizing hormone which, in turn, stimulates the Leydig cells. It seemed logical to suggest that supplementing DAA can stimulate testosterone production, but the theory has not been backed by studies. The only suggestion that has some potential is that DAA can be effective for untrained testosterone-deficient people, but it requires more research.

Panax Ginseng Extract

Panax ginseng, or Asian red ginseng, is famous among Asian-originated traditional medicine. Not only it is known as an enhancer for erectile function and sex drive, but it is also a proven stimulator which means it can make you more resilient and energetic.

There is also a study that shows that Ginsenoside, the main active component in the plant, is linked to elevated serum testosterone levels.

Fenugreek Seed Extract

Fenugreek seeds are popular in some cuisines, for example, Indian, for their tangy, bitterish taste that reminds of burnt sugar. But they were also studied and discovered to contain saponins. These organic substances can inhibit aromatization—the process of testosterone turning to estrogen. There also has been a study stating that fenugreek has an impact on serum testosterone levels in men.

Maca Root Extract

Maca, or Lepidium meyenii, is a Peruvian herb. It does not affect hormone levels, but it has been shown in research the potential to improve sexual function, mood, and energy levels—all things that we want to achieve.

Oyster Shell (Mollusc)

Oysters contain zinc, which, as we already know, is involved in testosterone production. Moreover, shell extract served as an aromatase blocker in a test study on laboratory rats, which stopped testosterone from metabolizing into estrogen and, thus, boosted its levels.


Boron is a mineral that increases the absorption of magnesium and vitamin D. What is more important, it reduces the levels of sex hormone-binding globulin. SHBG is a protein that binds testosterone molecules, making them inactive. Therefore, boron contributes to the elevation of free testosterone levels.


Testosterone is an anabolic-androgenic steroid hormone. It is mostly addressed as a male hormone, although is also present in the female body and is equally important.

Why Testosterone Is Important

For AMAB persons, the amount of testosterone in the organism has an impact on:

  • healthy development during puberty;
  • having a healthy and attractive appearance, e.g. good hair;
  • ability to gain and keep muscle mass;
  • production of the red blood cells in the bone marrow;
  • bone density;
  • levels of strength, stamina, endurance;
  • sexual function and fertility.

Benefits of Increasing Testosterone

Boosting your levels of testosterone closer to the full potential of your organism can help you become:

  • positive and confident;
  • strong and energetic;
  • fit and muscular (by improving your metabolism and the efficacy of your workouts);
  • more sexually active.

TestoFuel Possible Side Effects

Roar Ambition states that the manufacturing of TestoFuel occurs in FDA- registered and GMP-certified facilities which guarantees the quality of the product. Due to that, and the natural origin of its components, it is usually well-tolerated. However, these side effects of TestoFuel are still possible:

  1. individual sensitivity and allergic reactions, including rash;
  2. upset stomach and other gastrointestinal issues, such as nausea, vomiting, diarrhea, abdominal pain;
  3. elevated blood pressure;
  4. headache and dizziness.

Also, the supplement can have unwanted interactions with other medications you take. We recommend consulting your doctor prior to starting any new product and disrupting its use and seeking medical attention if you notice any possible adverse reactions.

How To Take TestoFuel

The best way to take TestoFuel is in the first part of the day, half an hour before you have a meal. The advised TestoFuel dosage is four pills per serving.


Attempts to boost T levels are very popular among men in their thirties and older. TestoFuel is a supplement intended to increase testosterone levels in the body. Although it was not clinically researched, it is pretty popular and has overall positive online feedback.


Is TestoFuel Safe?

It is mostly safe unless you have an individual intolerance. In any case, we recommend asking your healthcare provider if it can be beneficial for you to start taking it.

Does TestoFuel really work?

It has some positive reviews online, which allows suggesting at least some effect. However, without proper clinical research, the answer is down to the individual response of the body.

Is TestoFuel a steroid?

No, it consists mostly of micronutrients and natural extracts of herbal and marine origin.

Does TestoFuel cause hair loss?

It is unlikely, as it does not contain testosterone, but merely promotes its production by your own body. Therefore, you cannot have its levels too high which is usually associated with balding.
