Testosterone-boosting compounds are by far the most popular muscle-enhancing supplements on the market. Many guys take them to try and mimic the effects of taking anabolic steroids. While they won't do that, a high-quality testosterone booster will stimulate your body's natural testosterone production to boost protein synthesis, strength, and muscle-building potential.
One of the most popular testosterone boosters over the past few years has been TestoFuel from Roar Ambition. Many users swear by TestoFuel's ability to increase their strength, hypertrophy, and energy levels while others write it off as nothing more than an expensive placebo. So, we decided to do an in-depth TestoFuel review in order to get to the truth.
Read on to discover whether TestoFuel is the real deal.
TestoFuel is considered to be a revolutionary, exhaustively researched muscle building supplement with one very focused aim...to smash down the barriers to growth by opening your testosterone floodgates...

What is TestoFuel?
TestoFuel is a testosterone-boosting supplement manufactured by a company called Roar Ambition. Unlike anabolic steroids, it does not contain synthetic testosterone. Instead, it combines 10 natural ingredients to boost testosterone levels.
TestoFuel comes in capsule form, with each container holding 120 capsules. At a daily dosage of four capsules, that is enough for a 30-day supply.
TestoFuel Review: Pass or Fail?
TestoFuel claims to be able to do the following things:
- Increase muscle growth potential
- Boost testosterone levels
- Enhance strength
- Reduce body fat
- Improve mood
- Boost self-esteem
Each of these effects is supported by research on the ingredients that make up this product (we will discuss these in the next section). The dosages on the ingredients are in line with the clinical dosages used, which is really good to see.
The makers of Roar Ambition make it clear that you will not get the claimed results just by taking their product. You also need to be training intensely and following a healthy diet that is in line with your goals. If you are doing those things, the compounds contained in TestoFuel will give you an extra 5-10% in terms of strength and muscle-building potential.
Overall Verdict: PASS
Pros

10 TestoFuel Ingredients
TestoFuel contains ten ingredients, each of which has some research backing to support its ability to boost testosterone levels or increase energy. Unlike many competing products, TestoFuel does a good job of providing transparency about their ingredient dosages, which we have listed alongside each ingredient.
1. Vitamin D3 - 4000IU
Over a thousand biological processes are controlled by vitamin D. It can be acquired by being in the sun and is found naturally in fish and eggs. In addition to being a powerful "T" booster, vitamin D supplementation is known for strengthening bones.
According to a recent study, testosterone levels were 25.2% higher in males who took 3332 IUs of vitamin D daily for a year than in those who received a placebo.1
The combination of vitamins B6, D, and K2 increases testosterone receptor activity and enhances zinc and magnesium absorption.
2. Vitamin K2 - 18mcg
Vitamin K2 has been shown to improve testosterone supply and to be excellent for cardiovascular health.
Male rats in a Japanese study were given 75 mg/kg of K2 daily for five weeks. Blood plasma testosterone levels had increased by 70% by the trial's end, according to the researchers. Even more of an increase (90%) was seen inside the testes.2
3. Magnesium - 70mg
More than 300 bodily processes are regulated by magnesium. The majority of the body's enzymes need it as their main electrolyte. It keeps fluid balance, fuels cells, and boosts the level of bioactive, or free, testosterone.
Your serum testosterone levels will drop if you have a magnesium shortage.
Magnesium is a testosterone enhancer that is underutilized but incredibly powerful. Magnesium can unbind bound testosterone to increase its bioavailability, according to a recent in-vitro study. Magnesium blocks SHBG, a chemical that binds to free testosterone, which is why this occurs. This increases the "T's" accessibility to receptors.3
4. Zinc - 10mg
The body is unable to manufacture the necessary mineral manufacture zinc. It cannot store zinc either.
Zinc plays a significant role in the reproductive system while also boosting the luteinizing hormone that triggers the body to produce testosterone . It can prevent the aromatase enzyme from working, which makes it a testosterone booster as well.
Numerous studies have demonstrated that taking zinc supplements considerably raises the levels of bioactive (free) testosterone.4
5. D-Aspartic Acid - 2000mg
The non-essential amino acid D-aspartic acid works to increase serum testosterone levels in three different ways:
- It stimulates the creation of testosterone in the testes
- It facilitates more testosterone release from the pituitary gland
- This amino acid is a crucial link in the process of turning cholesterol into testosterone5
6. Maca Root Extract - 180mg
Maca root extract was once a mystical herb valued by Inca soldiers as a means of boosting their strength and energy levels when going into battle.
Recent research suggests that can boost exercise stamina and endurance, making it a good pre-workout ingredient.
Additionally, studies on maca have shown that it can raise happiness and mood. Increasing your level of relaxation will significantly enhance your sleep, which can have a significant favorable impact on testosterone levels. Other research has established the effectiveness of maca as a natural libido enhancer.6
7. Asian Red Panax Ginseng Extract - 100mg
The body's capacity to deal with physical, environmental, and emotional stress is significantly increased by the potent adaptogen ginseng. Its capacity to stimulate slow metabolisms and increase energy levels makes it an efficient weight-loss treatment.
Ginseng is a strong prolactin inhibitor, according to several investigations done on rats. In one study, American ginseng treatment resulted in a startling 50% drop in serum prolactin levels in the treated rats.7
Ginseng has also been shown to significantly increase nitric oxide production in the body (NO). This directly results in an improvement in the capacity to achieve and sustain an erection.
According to studies, Siberian ginseng can also raise the levels of two other essential hormones that are necessary for the release of testosterone:
- Adrenocorticotropic Hormone (ACTH)
- Adrenaline
8. Oyster Extract - 100mg
Oyster extract is well known as an aphrodisiac. It is rich in important fatty acids, vitamins, minerals, and amino acids. Numerous studies have demonstrated that oyster extract can help in the production of testosterone. The zinc level in oyster extract is an important characteristic. You'll receive 10 times more zinc, another known testosterone booster, than you would from a beef steak.8
9. Fenugreek Seed Extract - 50mg
Natural testosterone booster fenugreek (Trigonells foenum-graecum) contains two active ingredients that boost testosterone; Protodioscin and fenusides.
The herb fenugreek is also recognized as a libido stimulant and a testosterone booster.9
10. Boron - 8mg
The natural element boron is essential to human life. Many different kinds of green vegetables contain it. Recent scientific research indicates that boron plays a significant part in assisting your body in producing testosterone.
In a 2015 study, it was discovered that supplementing with 8mg of boron daily helped to raise free testosterone levels by almost 25%.10
Benefits of TestoFuel:
The following health benefits of Testofuel are all directly related to the product's ability to boost testosterone production. Testosterone supplements presuppose that you are training hard in the gym and following a sensible diet.
1. Increase Strength
When you increase your body's ability to produce testosterone, you have more strength potential. Studies have found that increased testosterone levels boost strength independent of muscle mass increase.
2. Increase Muscle Mass
The hormone testosterone is known as an androgen. As such it is involved in body maturation and sexual development, including the growth of sex organs, body hair, voice deepening, and other things. Anabolic effects of testosterone include the development of muscular mass, enhanced bone density, and other bodily growth.
The testosterone-boosting effects of TestoFuel mean that you will increase your ability to add muscle tissue to your body when you combine this supplement with intense training and weight-gain diet.
3. Reduce Body Fat
The main ability of TestoFuel to reduce fat comes as a byproduct of muscle mass increase. When you add muscle to your frame, your metabolism increases. That is because muscle tissue requires more energy to sustain itself.
4. Increase Libido and Sperm Count
Sexual excitement and activity causes a natural increase in testosterone levels. Male sexual activity is typically higher in men with higher testosterone levels.
Studies confirm the benefits of testosterone therapy for sexual performance and male reproductive function. Additionally, it demonstrates that testosterone must reach a certain level before there is no longer an increase in reaction.
Increasing your testosterone levels can improve your sperm count. However, excessive amounts of testosterone will have the opposite effect. To achieve testosterone levels high enough to decrease sperm count, though, you would have to use anabolic steroids or testosterone injections.
5. Increase Energy Levels
The creation of red blood cells, or erythropoiesis, is a process that heavily depends on testosterone. Our level of energy is severely impacted by low red blood cell production. Increasing testosterone level by supplementing with TestoFuel may increase erythropoiesis and restore your red blood cells to their normal levels. This will significantly boost your energy level.
6. Increase Bone Health
Bone mineral density is significantly influenced by testosterone. Men's bone density declines as they age and their testosterone levels fall. This increases the chance of osteoporosis and brittle bones. Athletic performance can be improved by having strong bones that support your muscles and internal organs.
Increases in the density of the spine and the hips have been shown in clinical studies on the impact of testosterone on bone density. However, it's not known if testosterone can lower the chance of fracture.
TestoFuel Side Effects
TestoFuel does not carry any major side effects. All of the ingredients in TestoFuel are completely natural. Although there are negative consequences of taking too much testosterone, the increases you will experience from a natural product like TestoFuel will not get to those levels.
Unlike steroids and prohormones, TestoFuel will not inhibit your body's natural production of testosterone. as a result, you do not need to cycle your use of this supplement. Nor do you need to undergo post-cycle therapy.
Some people may experience such minor side effects as bloating, gas, diarrhea, or constipation when they first take TestoFuel. This usually goes away after a couple of weeks.
