It stimulates and improves the circulation of the blood as well. One of the ingredients in its formula is Tribulus Terrestris. And it is well-known for being a natural stimulant that increases the production of testosterone, which results in improved sex life!
TestoFuel can definitely help with:
- Boosting the libido.

Ingredients of TestoFuel
This supplement is packed with testosterone-boosting ingredients. You don’t even have to look them up to know them and what they do!
D-Aspartic Acid or DAA
This ingredient is an amino acid. It stimulates the synthesis and release of testosterone. Studies show us a 42% increase in serum testosterone after only 12 days!
Studies also show, that when people consume 10 ml of Sodium D-Aspartate every day for 12 days, there is a significant increase in testosterone levels and Luteinizing hormone. The increase is 42% and 33% respectively. The formula contains 2.3 grams of DAA, and that’s great. But we would’ve liked it very much if they also utilized D-AA-CC which is more potent than DAA.
Magnesium and Zinc
Only DAA can best Zinc. This ingredient is known to be of great help to men that have low T-levels. Furthermore, it helps with reversing the effects of Hypogonadism, which causes deficiency of testosterone.
Magnesium is not as powerful as Zinc, but it also has properties that boost the levels of testosterone, and especially boosting total and free testosterone.
- When older gentlemen who have a slight Zinc deficiency start taking TestoFuel they experience a boost in testosterone. After 6 months there is an increase in serum testosterone from 8.3 +/- 6.3 up to 16.0 +/- 4.4 nmol/L where p=0.02. Zinc has an important part to play in regulating levels of serum testosterone.
- Levels of free testosterone increase at exhaustion after and before supplementation, when they are compared to levels of testosterone when resting. Exercise also boosts testosterone when compared to sedentary people. The increase is similar when looking at total testosterone. Simply put, supplementing with Magnesium will increase total and free testosterone for both athletes and sedentary people.
Vitamin K and D
Let’s talk about Vitamin D first. This vitamin is among the most effective of all vitamins in boosting testosterone. The form Vitamin D3 is optimal for testosterone and the huge dose of 5000 IU are amazing!
A study has shown that if you take Vitamin D for 1 year, it will boost your free, total and bioactive testosterone levels.
Vitamin K2 stimulates the synthesis of testosterone and reduces the deficiency of testosterone.
The majority of men have a deficiency of Vitamin K, and it is a great addition!
- People that were taking Vitamin D had significantly higher levels of free, total and bioactive testosterone levels. People that took placebo stayed close to their baseline, and there were no significant changes in testosterone levels among them. Vitamin D can increase levels of testosterone.
- Supplementing with Vitamin K can affect the levels of Vitamin K in the testicles. It can also alleviate lower synthesis of testosterone in the testicles caused by Lipopolysaccharides. Vitamin K can also inhibit inflammation signals and keep steady testosterone levels.
Panax Ginseng
Great choice! This is a herb that gives us Ginsenoside. This is a compound proven in human and animal research to increase testosterone levels. It has extra benefits. Namely, it can boost physical performance, and it also has benefits of an adaptogen herb. Those benefits are lowering stress and boosting mental and physical energy!
Panax Ginseng increases spermatozoa count and their progressive motility. There is also an increase in total, free and plasma testosterone when using this ingredient. It can also increase FSH, LH and DHT levels.
Fenugreek
This herb has several benefits like boosting sex drive, testosterone, endurance, and muscle growth. This herb is a perfect fit with the rest of the ingredients that boost testosterone and because this product was designed primarily for athletes and bodybuilders.
It is also very beneficial for men that want to gain muscle. This claim is based on a study done in 2010. The results showed that supplementing every day with 500 mg of Fenugreek and doing 8 weeks of resistance training significantly increases lower and upper-body strength. It also lowers the fat percentage significantly more than when compared with the placebo group. The results of the people that were supplementing compared to those that were getting placebo were significantly better!
Oyster Extract
About How TestoFuel Works?
Firstly TestoFuel is a great formula that mainly boosts testosterone and contains well-known ingredients. And secondly, the formula does not contain fillers or any fluff ingredients.
The fact that there is no fluff is great. Companies usually do that just to boost their brand name, it doesn’t have any real benefits. TestoFuel doesn’t need the fake boost of reputation. The ingredients and more importantly the effectiveness of its formula is more than enough to gain a good reputation.
D-Aspartic Acid or from now on DAA is dosed at 2.3 grams. And DAA is an amazing ingredient since it can boost the production of testosterone and also reverse some of the sings of low T-levels. Other ingredients like Magnesium, Vitamins K2 and D3, and Zinc support DAA. Their synergy is also great, and together they improve the environment for further boost T-levels.
Other than boosting testosterone, the people that created TestoFuel wanted to help people to gain muscle mass. Ingredients like Panax Ginseng and Fenugreek were added for that specific purpose. But if you want to see real benefits, you have to go hard in the gym!
There are no real downsides to using TestoFuel. But we like to nitpick, and we think that there are not enough of what we call premium ingredients, except for ZMA. We think that at a premium ingredient can be a big difference maker. But that’s just us.

Does TestoFuel Really Work?
This supplement was made for bodybuilders and athletes that want to boost their T-levels and gain muscle mass. But it can also be used by older gentlemen that want to improve their sex life.
All the ingredients in TestoFuel formula were carefully chosen to boost strength, improve sleep and allow quick muscle recovery. There are no side-effects. What makes TestoFuel special is not just the ingredients but the dosages. They were tested to get the perfect combination that provides the best results.
But the question remains, does it really work?
The ingredients of this supplement guarantee that this product will work for many, but there are no guarantees that it will work in 100% of cases. The ingredients proved to be more effective with improving sexual desire and function than gaining muscle mass or boosting T-levels.
Many of its ingredients are similar to multi-vitamins as they are often found in our everyday meals. Also, there are many negative online reviews of TestoFuel. Some people complained it took too long to see real muscle gain or boost in T-levels. But before we continue, we just want to stress the importance of exercising. TestoFuel can heal you greatly, but if all you do sit around on your but, there is no help. If you want real results, you have to put in real work! The manufacturer claims that if you exercise regularly and eat well, you will see the first results in 3 weeks.
Experiences with Using TestoFuel
It is an amazing feeling when you see the results of your hard work coming to fruition. All those hours at the gym, dieting and now you can see what you set out to achieve in the mirror. But that is so much easier said than done.
Now, people have different goals and reasons why they are working out. But everyone that was working on gaining muscle mass knows how important testosterone is, and how much of a difference maker it is.

About the Side-Effects of TestoFuel
Roar Ambition LTD is the manufacturer of TestoFuel. They are a reputable English company and that is always a plus. They also claim that their formula uses natural and 100% safe ingredients. But some of their ingredients are known to cause side-effects and especially if they are used for a longer time.
There are still no reported cases, but whenever you use a testosterone booster you should be careful. TestoFuel could potentially cause serious problems for people that have allergies. Keep in mind that nothing is truly 100% safe, and you could have an allergy that you are unaware of.
Ingredients like Oyster and Vitamin D can cause a high concentration of Calcium if used for a long time. DAA can cause bloating, gas and diarrhea in some cases. There is a possibility of stomach pain, vomiting, fatigue, sleepiness, headache, itching, and losing appetite. It is important to note that any of these side-effects can occur only after longer use.
People that have allergies should avoid TestoFuel. If you take too much it might cause some side-effects that are quite rare like a headache, fatigue, hypotension, nausea, and lack of sleep.
About the Price of TestoFuel
The price is monthly-based and one month of supplies is around $69. Every bottle has 120 pills and taking 4 pills a day equals one month. Now, taking TestoFuel for just one month is not enough to see the full extent of its benefits.
If you are aiming for big results, you should take TestoFuel for at least 2 months, but most likely 3 months. So if your goal is bigger, it is smarter to get enough for 3 months right away since that way you will avoid handling and shipping fees.
