What is Testofuel?

what is testofuel

Many men, despite working out long and hard, do not see the muscle gains that they are looking for.

This is likely because they have low testosterone levels, a crucial component in building muscle.

Testofuel is a muscle-building supplement1 that increases testosterone levels in the body2.

It is designed for bodybuilders and athletes looking to increase muscle mass quickly and safely.

It can also be used by older men who are looking to boost their testosterone levels.

Testofuel contains carefully selected ingredients that deliver the nutrients that the body needs to jump-start testosterone production.

These ingredients constitute essential amino acids, vitamins, and herbs whose efficacy is backed by clinical studies.

Other than boosting muscle growth, this supplement will give you increased energy and stamina, libido and reduce unwanted body fat.

Testofuel is manufactured by Roar Ambition, a UK company that makes numerous other dietary supplements.

It is produced in GMT and FDA certified facilities and meets strict European Union requirements.

Testofuel ships all over the world, and is distributed from Roar Ambition’s stores in the UK and USA.

This Testofuel review discusses more about this muscle building supplement, including its ingredients, how it works and what benefits you will get from it.

We will also advise you on where to buy it and the cost, and also present some reviews from people who are already using this product.

What are the ingredients in Testofuel?

testofuel ingredients

This t-booster is formulated from natural ingredients that have been tried and tested.

The manufacturer has disclosed all ingredients and their quantities to ensure that you understand just what you are consuming.

These ingredients include:

D-Aspartic Acid

This amino-acid plays a vital role in the production of the luteinizing hormone, which in turn, signals for the production of testosterone. In one study, when a group of men took D-aspartic acid supplements, their testosterone levels rose by 30-60%3.

Vitamin D

Vitamin D is produced when the body comes into contact with the sun. Studies have found that this vitamin kick starts the production of testosterone, elevates muscle mass, and improves bone health. It also increases endurance and reduces muscle soreness4.

Oyster Extract

Oysters are not only an aphrodisiac but an essential source of zinc. Zinc helps to improve reproductive function and health, and most importantly, slows down the conversion of testosterone to estrogen.

Asian Red Panax Ginseng

This Asian herb keeps the immune system in check. Ginseng is also used as an aphrodisiac, and studies show that even short term use of this herb increases testosterone levels. It also boosts the levels of nitric acid in the blood which improves insulin sensitivity contributing to fat loss5.


This mineral is useful in hundreds of bodily functions. It boosts endurance during physical exercise, and also aids in muscle recovery. Studies show that it plays a role in the production of testosterone in the body6.

Other ingredients used in this t-booster include:

  • Fenugreek.
  • Vitamin B6.
  • Vitamin K2.
  • Zinc7.

How does Testofuel work?

testofuel pills

Testofuel does not contain testosterone, but its ingredients work together to help the body increase its testosterone production.

Studies have proven that testosterone is crucial for protein synthesis, which generates muscle mass and kills fat.

High testosterone level also blocks the production of cortisol, the stress hormone which has been seen to break down muscle.

The ingredients in Testofuel also increase the production of red blood cells in the body, increasing the flow of oxygen.

When the body has sufficient oxygen, you will feel energized and will have endurance to work out harder for longer.

Raising testosterone levels also means that your body will be able to repair tears in the muscle fibers caused during workouts.

This regeneration is what makes muscles more prominent and it cannot happen appropriately without sufficient testosterone.

The result is an increase in muscle and a well-built physique.

Testofuel reviews & complaints

Testofuel is available for purchase from the official website, where it has numerous positive reviews.

Since it is not sold elsewhere, we could not find many independent reviews for comparison.

Here are some of the reviews from the official website:

Jake says:

“I just finished my fourth-month taking Testofuel. The first month I didn’t notice much in the way of size or strength but a very nice change in overall mood and an elevated sex drive. By the end of the second month, I added roughly 6lbs of lean mass and was breaking through my plateaus right and left. The elevated mood and sex drive continued as well.

Jose reports:

“My mood was bad, energy levels were low and I had trouble wanting to get myself in the gym. For me, Testofuel took a while to get started; there wasn’t much going on in the first month. But then in my second month, I noticed that I had more energy and I couldn’t wait to get to the gym.”

Ian adds:

“For the first 2 weeks I was like I don’t feel anything. The third week I started seeing how tight and vascular I started to look. I started feeling amazing in the gym and my mind and muscle connection were off the chain. The price is definitely worth the results. I won’t ever switch to another product.”

Cyrus, from Denmark, reports:

“When I first started taking TestoFuel I was sceptical, but within the first week, I felt the system working. I was much more active and motivated to hit the gym. Along with a good diet and regular training, TestoFuel made me gain 5kg in only 2 months! I have dropped 3.5 inches off my waist while I got stronger and felt more alive than any other time before when I was dieting.
