So How does TestoFuel Work?

How can TestoFuel transform your physique and how it can improve your overall workout program? The official website has stated that this brand will give you more energy, fast muscle growth and promotes fast recovery.

This supplement gives the said benefits by providing a natural and safe, yet a very potent ingredients.

As mentioned above, TestoFuel does not contain actual testosterone, but works by helping your body to release its own testosterone.

With up-to-date formula, the proprietary blend of this brand is clearly laid out for you to see (pictured above) and provides the optimum servings so that you get the full potential of each key ingredient.

D-Aspartic Acid

Known as D-AA, D-Aspartic Acid is the key ingredient of TestoFuel. It is an amino acid regulator of testosterone synthesis and acts on a stimulatory receptor.

Dieters and bodybuilders alike use D-AA to help improve their body’s testosterone production, while some use it to aid male fertility.

Various studies have suggested that D-AA supplementation showed an increase in free testosterone in humans by about 40%, and helps enhance luteinizing hormone by 45%.

So D-Aspartic acid is the best amino acid to take if you want to boost your testosterone levels, reduce estrogen levels and increase muscle growth.


Vitamin D

This is a surprise ingredient in TestoFuel as vitamin D is not often used as a testosterone boosting agent. But can it truly help aid hormone production?

Vitamin D is an essential nutrient that we normally produce from sunlight exposure.

Various studies suggest that vitamin D deficient men had much lower free testosterone levels and higher levels of oestradiol and leutenizing hormone. These factors poor reproductive health.

According to National Institute of Health, vitamin D do support hormone production as receptors are found for this vitamin in the hypothalamus and pituitary glands.

These glands produces hormones responsible for both metabolic and sexual health. So now you know that vitamin D can help increase your free testosterone levels.

If you live in the UK where you can get little sunlight exposure, then you are probably deficient in vitamin D. TestoFuel can definitely help.

Oyster Extract and Zinc

Oyster extract plays an important role in testosterone production because of it’s a good source of zinc, an essential mineral involved in regulating many enzymes.

It is a fact that zinc deficient people have low testosterone levels which leads to various health conditions such as low sperm count, impotence, estrogen level increase that causes gynecomastia, and many others.

So it is important to get enough zinc to prevent hormone imbalance and have a enough testosterone levels. And one way to meet this need is by taking oyster extract.

TestoFuel has “Siberian” ginseng (not Asian or Panax) which is also known as eleuthero.

While some men use ginseng to help increase their testosterone levels, this herb doesn’t directly affect your hormone production but only supports it. How?

Ginseng has tons of health benefits that can affect your both your manhood and workout performance.

First off, ginseng is proven to help improve athletic performance (endurance, recovery, breathing, etc.). It also help you recover fast from any strenuous workouts.

Ginseng also help improve mental performance, prevents the onset of heart disease, depression, osteoarthritis, tuberculosis and many others.



Scientifically known as trigonella foenum-graecum, fenugreek is a popular herb among herbalist especially in Arabic and Indian regions.

Like other herbs, fenugreek is health beneficial as it is widely used as aphrodisiac (libido enhancer) and testosterone booster. It is also used to alleviate blood sugar metabolism issues such as diabetes.

Fenugreek also promotes weight loss, appetite reduction, lowers triglycerides, estrogen levels, blood cholesterol levels and many others.

Other ingredients such as magnesium, vitamin B6 and vitamin K2 are all known beneficial for promoting testosterone production.

No other instructions found online.
