Full Testofuel Review

TestoFuel is a testosterone boosting supplement that contains only natural ingredients and has a reputation that’s second to none.

There’s an incredibly good buzz about this product and the before and after pictures some TestoFuel users have posted online show it’s a product that delivers results!

The supplement is mainly for people who are having difficulties gaining extra muscle and want to set their training on fire.

However, as with any other testosterone booster, it has the potential to help men who are struggling with libido issues and those who find their sexual performance is no longer up to scratch.

TestoFuel is the result of intensive research. It also contains some of the best natural testosterone boosting ingredients you can find.

This probably explains why so many people love the product so much.

Although it’s not marketed as a legal steroid or a steroid alternative, TestoFuel’s supplement can still be used in that way.

Its nutrient-powered formulation is safer than steroids and will provide a similar level of power.

Testofuel can increase your levels of testosterone naturally. This is thought to be the missing link that is needed build muscle.

You lift the weights, you drink your protein powder – but where are your muscle gains? Testofuel gets you the results

What are the Benefits of Using TerstoFuel?

According to the Roar Ambition’s unusually informative marketing material,  TestoFuel provides a significant boost in testosterone that results in five key benefits:

  • Provides “real” muscle growth
  • Reduces body fat
  • Increases strength
  • Improves the mood
  • Boosts self-esteem

As you will likely be aware, the first four benefits are normal testosterone benefits.

As for the fifth claim, anyone who has less body fat and more muscle is going to enjoy a greater feeling of self-esteem.

Steroid users will be quick to point out steroids can do all these things too.

There is no arguing with that. However, the big difference is, TestoFuel is designed to do them without crippling normal testosterone production or damaging the health.

Additionally, TestoFuel is a safe and natural product that can be used for the long-term.

There is no need for cycling. Nor is there any need for a post-cycle therapy (PCT). Furthermore, unlike steroids, TestoFuel won’t get anyone banned from competitions or cause them to run foul of the law.

Why Testosterone is Important

Testosterone is an anabolic steroid produced in the body. It’s also the male sex hormone, but women produce small quantities of testosterone in their bodies too.

During our early years of life, testosterone aids growth and physical development.

Throughout life, testosterone remains an incredibly important steroid hormone that influences many biological processes:

  • Bone mass
  • Sex drive and fertility
  • Muscle growth and strength
  • Cardiovascular health
  • Concentration and focus
  • Memory and cognitive function
  • Healing
  • Fat burning
  • Aging
  • Health and vitality

Testosterone also aids human growth hormone (HGH) production.

In fact, the two appear to have a symbiotic nature that allows each to influence the other for the better.

The Need to Boost Testosterone (Is It Really Necessary?)

Although testosterone levels are high during early life, production rates peak at adolescence.

After that production falls off. The amount of testosterone produced in the body continues to decrease with each passing year.

Apart from causing a loss of vitality, low testosterone levels can really hamper attempts to build muscle or improve athletic prowess.

In addition to these things, lack of testosterone can also interfere with fat burning capabilities, reduce feelings of desire, and hinder sexual capabilities.

However, other benefits aside, the two main reasons men take testosterone boosters are to build muscle and to rejuvenate their sex drives.

How it works

How TestoFuel Works

TestoFuel provides a combination of nutrients and plant extracts that tease the body into producing extra testosterone.

This is very different from anabolic steroids, which more or less take the place of testosterone.

By doing this, steroids ruin normal testosterone production.

That’s why they have to be followed by a PCT.

In addition to helping the body produce more testosterone, the TestoFuel formulation also provides ingredients that can help maintain circulating testosterone levels for as long as possible.

People who are using the supplement to increase muscle bulk and strength will still need to train hard.

A good training routine is always the key to muscle growth.

Fortunately, by boosting testosterone, TestoFuel will increase energy and vitality. This will enable TestoFuel users to train harder than they could do without it.

Men who wish to use the product to enhance their sex drive and sexual performance may not need to train.

Naturally Increase Testosterone

However, research shows getting more exercise is a good way to naturally elevate testosterone.

Furthermore, some of the ingredients in TestoFuel have been shown to deliver the most benefit when used alongside resistance training.

So if you want to get the best from the product spending some quality gym time is always a good idea.

A Look at the Formulation in Detail (What the Ingredients Do)

One of the best things about TestoFuel is it’s a completely natural formulation.

It only contains vitamins, minerals, and other ingredients taken from nature.

Because it’s a natural product, it’s kind to the body and will not cause the side effects that steroids and other chemical compounds do.

Can natural ingredient really get the job done? If you doubt it, you may be pleasantly surprised.

Continue reading to learn what this natural testosterone boosting supplement has to offer.

Vitamin D3 (5000 IU)

There are a few forms of Vitamin D. They are often grouped together and referred to as Vitamin D.

Vitamin D is the sunshine vitamin. It’s so called because the body can manufacture it when sunlight makes contact with the skin.

The interesting thing about Vitamin D is it’s not a vitamin at all. It’s a hormone.

There is evidence to suggest Vitamin D may enhance muscle function and provide improvements in mass and strength.

Additionally, the results of a study published in Hormone and Metabolic Research indicate a relationship between Vitamin D and testosterone production.

Vitamin K2 (18 mcg)

There are two forms of Vitamin K. Vitamin K2 is present in pork, chicken, and soft cheeses. You get Vitamin K1 from spinach, kale, Brussels sprouts, and other plant sources.

Vitamin K2 works especially well in the presence of Vitamin D3. The two share a symbiotic nature that allows them to team-up and initiate a greater testosterone release.

Vitamin K2 can also boost testosterone when working alone.

The results of one study suggest it may increase circulating testosterone quite considerably.

However, it’s good to see that, in the TestoFuel formulation, Vitamin K2 does not have to go it alone and has Vitamin D3 to help it along.

Vitamin B6 (5 mg)

Vitamin B6 does a lot of good things.

One of them is helping the body extract energy from food and supplements.

For that reason, you will find Vitamin B6 on the list of ingredients for most energy drinks.

Extra energy is always a good thing. Especially if you are putting in a lot of hours at the gym. However, Vitamin B6 does more than invigorate the body.

Vitamin B6 boosts serotonin, which is known as the “happiness hormone”. In so doing, this important vitamin may help you to train with a better state of mind.

Another thing Vitamin B6 does is support testosterone synthesis. It also enhances target organ response to testosterone.

Magnesium (200 mg)

Magnesium is an important mineral that benefits the body in many ways. Natural sources include spinach, legumes, whole wheat, and even dark chocolate.

It works with ATP to help provide energy and power muscular activity. It’s also essential for the synthesis of proteins and nucleic acids.

More importantly (for a formulation such as this), research shows magnesium is a testosterone booster.

The results of one study are particularly noteworthy. They suggest magnesium provides a greater testosterone boost to those who exercise regularly.


Zinc (10 mg)

Most people are aware zinc boosts testosterone.

More importantly, numerous studies prove this ability.

The results of one six-month study show the elderly male participants almost doubled their serum testosterone levels via the daily use of a zinc supplement.

The same research team also did a similar experiment with younger males.

However, instead of increasing the men’s zinc intake, they decreased it. The result was a significant decrease in testosterone.

Some research suggests pairing zinc with magnesium enhances the testosterone boosting ability of zinc, so it’s good to see both minerals are included in the TestoFuel formulation.


D-Aspartic Acid (2300 mg)

D-aspartic acid (D-AA) is an essential amino acid. The body cannot make it. You have to get it from food or supplements.

It’s a good addition to the TestoFuel formulation because it stimulates the release of luteinizing hormone.

This is an important hormone that encourages the release of testosterone and human growth hormone (HGH), both of which provide invigoration and support rapid muscle growth.

The results of one 90-day study suggest D-AA supplements may increase testosterone by up to 60% and also increase sperm count by up to 100%.

The important thing to know is, HGH and testosterone are both powerful anabolic hormones that appear to work best when boosted together.


Panax Ginseng (100 mg)

When it comes to famous herbs, ginseng is in a class of its own.

It’s renowned for being a potent health tonic, an aphrodisiac, and for its ability to heal a variety of ills.

Asian herbalists have been using this powerful adaptogen for more than 5,000 years and consider it to be a “life-giving herb”.

Can ginseng really help you to live longer? That’s a claim that’s pretty hard to prove.

However, research proves its value in multiple areas and one of them is enhancing muscle growth.

This may be due to the herb’s ability to increase luteinizing hormone.

However, researchers in Italy suggest ginseng boosts testosterone because the ginsenosides react in a favorable way with the hypothalamus-pituitary-testis axis.

There are several forms of ginseng, but panax ginseng (Korean ginseng /red ginseng) appears to have the most power.

Fenugreek Seed (100 mg)

Fenugreek is a spice that most people will be familiar with. It’s a key ingredient in curries.

However, fenugreek is more than just a flavorsome spice. It’s a natural testosterone booster as well.

Could this explain why the Kama Sutra was written in India?

Who can say? But there can be little doubt about fenugreek’s ability to increase testosterone. There’s research that proves it works in this way.

The testosterone boosting ability of fenugreek is likely partly due to the fact that it’s a good source of zinc and magnesium.

However, fenugreek also contains compounds that prevent too much testosterone from being bound by sex hormone binding globulin (SHBG).

When testosterone is bound by SHBG, it’s useless to the muscles because they cannot receive it.

Boosting testosterone production is only have the battle. By ensuring circulating testosterone levels remain sufficiently high, fenugreek helps the muscles get all the help they need.

Oyster Extract (100 mg)

Oysters are one of the most popular libido-boosting foods in the world. Even people who have never eaten oysters will have heard what they can do.

Why are oysters are so good for boosting the sex drive? It may be due to the fact that they are an exceptionally good source of zinc, but there could be other reasons as well.

Whatever the reasons may be, research shows oyster extract enhances libido and increases testosterone.

Additionally, it also appears to have the ability to help keep testosterone levels high by preventing too much of it from converting to estrogen.

Testofuel’s Celebrity Endorsement

TestoFuel is enthusiastically-endorsed by Robby Robinson, who appears to love the product.

Although you would not know it to look at him, Robinson is over 70-years old.

Robbie Robinson is a fan of Testo Boosting

He’s been involved with bodybuilding for a long time and used to train alongside Arnold and the other legends at Gold’s gym.

A 2-time Mr America and 5-time Mr Olympia, Robinson has taken the top spot at an incredible number of competitions.

Known as “The Black Prince” and “Mr Lifestyle”, Robinson is also known for the most peaked biceps ever to grace the sport.

Robinson retired from competition when he was 55 but, nearly two decades later, he’s still pumping iron to maintain his incredible shape.

The only real difference is, these days, he’s added TestoFuel to his daily routine.

One of the most inspirational things about Robinson is he built his incredible physique the natural way and admits he was not aware other bodybuilders were using steroids.

He states there are “better ways to do it”, is a firm believer in testosterone boosters and says TestoFuel is a great product that works for him and he’d “recommend it in a heartbeat”.

As far as celebrity endorsements go, this one takes some beating. Robinson is the living proof that it’s possible to excel without steroids and his credibility rating is through the roof.

TestoFuel Side Effects

TestoFuel does not have any known side effects. Everything TestoFuel customers have to say about the product is good.

Hit or Miss? (Is TestoFuel a Good Testosterone Booster?)

TestoFuel is not just a good testosterone booster, it’s easily one of the best. It contains a well-picked blend of natural ingredients with proven abilities.

The fact that so many customers are boasting such good results also shows Roar Ambition has got it right with this product.

However, the strong endorsement Robby Robinson provides is probably the biggest proof of the formulation’s power.

Robinson knows the bodybuilding game and is well qualified to differentiate between the good supplements and the bad.

Furthermore, his refusal to use steroids is an example to us all. You’ve only got to look at his physique at 70+ years to see how well the right combination of training, diet, and supplements can work. If he places his faith in TestoFuel, it says a lot.

It also has the advantage of a reasonable price tag and a money back guarantee.

If you want something to boost your testosterone in a safe and natural way, you simply won’t find a better option than TestoFuel. It’s as simple as that.

Where to Buy Testofuel

You can only buy TestoFuel from the official website. It costs $65 per bottle.

Each bottle contains 120 capsules and, when used at the normal dose of four capsules per day, will be good for a month.

As far as the price goes, $65 is not bad at all. Especially for such a high-quality product.

However, those in search of an even better deal have the opportunity to take advantage of the bulk buy incentives.

At the time of this TestoFuel review, the best deal on offer was the Ultimate Muscle Gainer’s Package, which allows customers to receive four bottles of TestoFuel for the price of three and get free worldwide shipping.
