Building muscle is tough work.

It takes hard, heavy consistent training, a lot of protein and the right supplements. And the Number One supplement that you need is Testosterone.

Now, there are dozens of products on the market that claim to give you crazy testosterone boosting results. But what if there was one mega supplement that combines 8 of the most scientifically backed ingredients into one formulation that really delivers the ‘T” boosting results that we’re all after.

Well, there’s a testosterone boosting product that’s been getting a whole lot of hype lately that claims to be that solution to your ‘T’ enhancing efforts.

It’s called Testofuel.

In this mega Testofuel review, you are going to discover everything you need to know to be able to decide whether or not you should buy Testofuel. You’ll also discover why Testosterone is so vital to the muscle building equation and what else you need to do to max your mass building potential. In short, we want this to be the only Testofuel review you’ll ever need!

What Is Testofuel?

What is Testofuel?

Testofuel is a weight gain supplement which comes in capsule form. It is intended to boost testosterone levels which, in turn, increase strength and muscle size. Testofuel is one of the few boosters on the market which is supported by clinical studies.

Testofuel promises to allow you to . . .

  • Increase your body’s natural testosterone production
  • Pack on lean muscle mass
  • Boost your energy levels
  • Max out your strength potential
  • Enhance your sex drive
  • Strip off body fat

And it promises to do all of this completely naturally without the aid of dangerous illegal steroids.

Testofuel is not an alternative to testosterone. There are no synthetic ingredients in the product profile. Rather it contains completely natural, herbal ingredients that have been scientifically shown to enhance your body’s natural ability to produce more testosterone naturally.

How Does Testofuel Work?

Even though the ingredients that have gone into Testofuel are all completely safe and natural, they are also very powerful. Individually they work well, but when combined synergistically they produce a pronounced effect that is many times what you would get from taking the ingredients individually.

Testofuel does not actually deliver more testosterone to your body. What it does do is to help your body to release more of its own ‘T’. While your current levels of testosterone may be sufficient to allow you to go about your normal day-to-day activities, if you are intent on building muscle, you need more. Testofuel will help to increase testosterone.

Spotlight On Testosterone

Testosterone Spotlight

Testosterone is the main male sex hormone in the human body. It is made in the Leydig’s cells which are located in your testes. Normal production of testosterone is between 2.5 and 11 mg per day. The testosterone molecule floats around in the body. This brings on a number of changes that include building lean muscle and developing male sexual characteristics.

Testosterone ‘parks’ in special receptors located in muscle cells. It will deliver the message to the cell to build more muscle. It will then unpark and travel around looking for another receptor site to park and deliver its message.

In most guys, 2 percent of testosterone is unbound to protein. This is known as free protein. 54 percent is bound to albumin and other proteins and 44 percent is bound to sex-hormone binding globulin (SHBG).

Male hormones, primarily testosterone are the drivers of all the changes that boys go through during the years of puberty and later in adolescence. Male hormones contain androgenic and anabolic effects.

Androgenic effects involve changes in both the primary and secondary sex characteristics. These include the size of the penis and testes, deepening of the voice, facial hair growth, improved efficiency of the nervous system, and enhanced levels of aggressiveness.

Anabolic effects include increasing muscle protein synthesis by increasing the transport of amino acids across cell membranes. Anabolics are also anti-catabolic (muscle depleting). They also inhibit the release of cortisol which works against muscle building. Testosterone competes with cortisol for receptor sites, as well as reducing cortisol secretion.

Testosterone also increases the release of other anabolic hormones such as Insulin-Like Growth Factors. It also speeds up erythropoietin synthesis.

Testosterone & Muscle Repair

When you train hard with weights you are not actually building muscle. In fact, you are doing just the opposite. Heavy and hard training places stress on your muscle cells. This causes mini tears in the fiber that start to break your muscles down.

It is only after the workout that you are able to build muscle. But this will only happen if you provide your body with the muscle building ingredients that it needs to rebuild and recover from the workout. The idea is that the torn muscle fibers will repair to become a little bigger and stronger than they were before the workout.

However, you will only be able to build your muscles back bigger and stronger if your body has what it needs to do the job.

And what it needs to do the job more than anything is testosterone!

If you don’t have enough testosterone to regenerate new muscle fibers you simply will not grow. Your goal then, should be to find ways to increase testosterone production.

Testosterone & Workout Recovery

Another key factor in the whole muscle building equation is workout recovery. You want to be able to recover from your workout as quickly as possible so that you can get to back to the gym and start the process of muscle creation all over again.

The more ‘T’ you have running through your system, the more quickly you will recover from your workouts. Higher testosterone levels also provide you with more energy and endurance to allow you to train harder for longer.

Testosterone also encourages the body to release more of the second most important hormone in the muscle building equation – human growth hormone. These two together will deliver a one-two knockout punch to ensure that you mass building potential is maximized.

Testofuel VS Steroids

Testofuel vs steroids

Testofuel is NOT an anabolic steroid. Steroids are illegal in the United States and are banned by sporting organizations around the world. They are synthetic (man-made) substitutes for certain hormones that the human body produces in order to get bigger and stronger. Of course, the main hormone made by the body is testosterone.

Steroids are used legally for legitimate medical uses. Of course, they are also used to increase athletic performance and enhance muscle mass. Medical treatments for steroids include . . .

  • Appetite Stimulation
  • Gender Identity Disorder
  • Hormone Replacement Therapy in Men with Low Testosterone Levels
  • Increase in Libido in Men Due to Low Testosterone Levels or Hypogonadism
  • Increase in Muscle Mass (For Patients with Chronic Wasting Conditions Such as Aids or Cancer)
  • Induction of Male Puberty
  • Male Contraception
  • Stimulation of Bone Marrow
  • Stimulation of Growth

Using anabolic steroids in the United States to increase muscle mass was made illegal by The Anabolic Steroids Control Act of 1990.

There is no denying that steroids, in conjunction with training and muscle building nutrition, are an effective way to build muscle. It’s not unusual for a guy to pack on 20 pounds of muscle in a couple of months when they start taking steroids.

However, there is a price to pay for that crazy amount of mass gain. In fact, there is a whole shopping list of side effects that come with steroid use. These include, but are not limited to . . .

  • Acne
  • Anxiety
  • Bad Breath (Halitosis)
  • Baldness
  • Breast or Prostate Enlargement
  • Cancer
  • Fluid Retention
  • Decrease in Testicle Size
  • Delusions
  • Depression
  • High Blood Pressure
  • Impotence
  • Liver, Kidney, and Heart Failure
  • Pain During Urination
  • Rage
  • Reduced Sperm Count
  • Trembling
Steroid Side Effects

When you use a completely natural, herb-based testosterone booster, you are not going to have to worry about these side effects. However, there may be some herbal ingredients that do carry some side effects.

 However, we need to be realistic here – Natural T Boosters will never provide you with the same results that you will get from anabolic steroids. Any marketing that promises that it will is simply hype – don’t believe it!

But what a good booster product can do is to dramatically increase your body’s natural production of testosterone. This will allow you to build more muscle, get stronger and cut your body fat levels with none of the side effects or potential health problems that come with illegal steroids.

Testofuel VS Prohormones

Testofuel is NOT a prohormone.

There’s a lot of confusion about prohormones, with many people confusing them for testosterone boosters and steroids.

Prohormones are what are called precursors to anabolic steroids. They fall somewhere in between T enhancers and steroids. They are chemical precursors of hormones and their synthetic equivalents in the form of steroids. Within them are the ingredients that the body needs in order to release the hormones that are required to build muscle. Of course, the most important of these hormones is testosterone.

Prohormones are not as toxic on the body as steroids. But they do still come with a number of worrying side effects. Anyone under the age of 19 should stay away from them as they will wreak havoc with your still developing puberty and endocrine system.

Most prohormones are illegal in the US. However, there are a few of them that are still legally available, including . . .

  • Epistane (sold as Havoc)
  • Superdrol
  • Masterdrol

Prohormones are especially troubling to the liver. If you’re on prohormones, you had better not be drinking any alcohol, because the two together will overstress the liver!

Even worse, prohormones will slow down your body’s natural production of testosterone. That’s why you need to cycle your use of prohormones.

When you take Testofuel you do not have to worry about such problems as your liver being adversely affected or your body reducing its natural ‘T’ supply.

Prohormones will also show up on drug tests, you if you play a sport or are an athlete. So, taking them could put your career at risk!

Because it is completely natural and safe, Testofuel will not show up on any drug tests !

Testofuel VS Prime Male

Prime Male is a main competitor to Testofuel. However, it is designed primarily for older men. Testofuel is for all guys who are intent on building muscle mass. Prime Male also does not include fenugreek and is more expensive.

Testofuel Ingredients

TestoFuel Ingredients

An immediate plus for this product is that it breaks down the ingredient list on the label, specifying how much of each item it contains. Not many supplements provide this detail. This lets you know exactly how much of each product is going into your body.

Testofuel ingredients combines a blend of Oyster Extract, Vitamin D and D-Aspartic Acid to triple your muscle building potential. Each of these supplements have been clinically proven to boost testosterone levels in healthy males.

But there’s more – Testofuel also includes such proven testosterone boosters as ginseng, fenugreek, vitamin B6, magnesium and Vitamin K2. When you take a single supplement, even if it’s proven to be the best testosterone booster supplement on the planet, it will give you some serious results. But when you stack 8 of the absolute best ‘T’ enhancers together into a super formulation, the power of synergy works to super charge the effect. That is what Testofuel can do for you.

Oyster extract is an ingredient that you won’t find in most other Testosterone boosters, making it one reason why Testofuel stands out from the pack.

Zinc has been scientifically proven to be linked with boosting testosterone levels and oysters are one of the best ways to get it.

All of the ingredients that make up Testofuel are completely natural. It does not, however, contain testosterone but rather a blend of ingredients designed to boost the body’s own natural production of testosterone.

Let’s look under the hood to really get to grips with the Testofuel nutrient profile.

Oyster Extract has a well deserved reputation as an aphrodisiac. It’s loaded with amino acids, vitamins, minerals and essential fatty acids. Oyster extract has been shown in various studies to assist Testosterone production. A key feature of oyster extract is its zinc content. You’ll get 10 times more zinc, which is another proven ‘T’ booster, than a beef steak. There are 100 mg of oyster extract in Testofuel.

Ginseng is a powerful adaptogen that greatly improves the body’s ability to cope with physical, environmental and emotional stress. It is an effective weight loss aid due to its ability to rev up sluggish metabolisms, and boost energy levels.

A number of studies with rats have revealed ginseng to be a potent inhibitor of prolactin. In fact, in one study, rats who were treated with American Ginseng had an astounding 50% reduction in their levels of serum prolactin.

Another huge benefit of ginseng is its proven ability to increase the body’s natural production of nitric oxide (NO). This directly leads to an increased ability to get and maintain an erection.

Ginseng is one of the world’s most commonly used adaptogens. It has also been used for centuries to boost sex hormone production, including testosterone.

Studies have shown that Siberian Ginseng can also enhance the levels of two other key hormones which are vital to testosterone release . . .

  • Adrenocorticotropic Hormone (ACTH)
  • Adrenaline

Testofuel contains 100 mg of Siberian Ginseng.

Fenugreek (Trigonells foenum-graecum) is a hugely popular natural testosterone booster. The active compounds that increases testosterone are protodioscin and fenusides.

Fenugreek is a herb that is a popular ingredient in many curries. It is established as a booster of testosterone as well as a libido enhancer (3).

There are 100 mg of Fenugreek in Testofuel.

D-Aspartic Acid is a non-essential amino acid which acts in three ways to boost your testosterone levels:

  • It signals testosterone production in the testes
  • It paves the way for greater testosterone release through the pituitary gland
  • It is a vital link in the conversion of cholesterol to testosterone

There are 2300 mg of D-Aspartic Acid in every capsule of Testofuel.

Magnesium controls more than 300 functions in the body. It is the primary electrolyte used by almost all of the body’s enzymes. It maintains fluid balance, gives energy to cells and increases the amount of bio-active, or free, testosterone.

Magnesium deficiency will lower your testosterone levels.

Magnesium is a little appreciated but highly effective booster of testosterone. A recent in-vitro study showed that magnesium is able to free up bound testosterone in order to make it more bio-available. This happens because magnesium inhibits SHBG, which is a molecule that bonds to free testosterone. This makes the “T” more available to receptors.

Zinc is an essential mineral that the body cannot synthesize by itself. Neither is it able to store zinc. Zinc is heavily involved with the reproductive system.

It is also a testosterone booster, with the ability to inhibit the aromatase enzyme. This reduces the conversion from testosterone to estrogen.

Many studies have shown that supplementation with zinc significantly increase the levels of bio-active (free) testosterone.

Most people have never heard of Vitamin K2. It can be found in such foods as cheese, egg yolks, butter, fermented foods and butter. As well as being great for cardiovascular health, K2 has also been clearly seen to increase ‘T’ supply.

In a Japanese study, male rats were fed 75 mg/kg of K2 for a period of 5 weeks. At the end of the trial, the researchers measured a 70% increase in blood plasma testosterone levels. Inside the testes, the increase was even bigger (90%).

Vitamin D regulates in excess of 1000 bodily functions. It occurs naturally in fish and eggs and can be obtained through exposure to the sun.

It is well known as a bone strengthener, but also is a potent “T” booster.

A recent study showed that men who took 3332 IUs of Vitamin D daily for a year had 25.2% more testosterone than a placebo group.

Vitamins B6, D and K2 work together to stimulate testosterone receptors and improve the absorption of zinc and magnesium.


For guys who are trying to build muscle, the blend of 8 premium ingredients that constitute Testofuel promises to produce the hormones and other compounds that it needs to increase strength, lean muscle and power while also enhancing virility.

So, does it work? Yes, but not immediately. You’ll need to take the product for at least two weeks to realize noticeable benefits. By then the constituent ingredients will have saturated your system and built up quantities sufficient to have an anabolic effect on your body. The key to success with this, as with all supps, then, is consistency.

After those first two weeks you will notice your strength levels creeping up, your muscles will look fuller and feel more pumped. The energy that you get from an effective testosterone booster like Testofuel is not the type of quick release energy that comes from a pre-workout supplement. Rather, it is a longer lasting, sustained throughout the entire day, including in the gym and the bedroom.

Apart from contributing to muscle hardness, pump and size and increasing your energy levels, Testofuel will get you leaner. This allows you to overcome the loss of strength and mass that comes with traditionally leaning out.

It should be noted that Testofuel is a supplement to a sensible diet and training regimen. If you are not eating a high protein diet and getting enough calories into your system, you will not realize the benefits that have been described.

What Else Should You Be Doing To Build Muscle?

Working Out

Building muscle requires that you train hard and consistently in the gym with weights, eat for muscle gain and supplement smartly. Testofuel will help you to cover the third part of that equation. Here’s what you need to do to make the most of the other two . . .

Train hard and heavy with compound exercises. Those are the big multi joint moves that work a number of muscles in your body together. These are the key compound moves that you should be doing . . .

  • Squats
  • Deadlift
  • Bench Press
  • Pull Ups
  • Military press

Perform 3-4 sets on each exercise going for 6-8 reps on each set.

As far as your nutrition goes, eat every 3 hours, aiming to take in 30-40 grams of quality lean protein at every meal. Your fats should be about 40 percent, focusing on healthy oils, nuts and fatty fish. Limit your simple carbs, going instead to low glycemic index complex carbs like vegetables.


The recommended dosage is four tablets per day. Each container contains 120 tablets. Tablets can be taken at any time of the day as all of the ingredients store readily within muscle tissue.

You should take this supplement even on your non-training days. You will also boost your daily energy levels being noticeably higher. This is great for those who train after a long day at work. When you’re feeling drained, Testofuel will provide that boost to get you into the gym and hitting the weights.

Side Effects

There are no known side effects associated with Testofuel. This product is completely natural and should not be confused with a synthetic testosterone steroid compound. Unlike prohormones, Testofuel will not slow down your body’s natural ability to produce testosterone.


Testofuel combines a whole host of top-grade ingredients all in one product. This may allow the user to cut out some of the other supplements that they are using, thus reducing their overall supplement bill.

Testofuel is available at three different deal options as follows . . .

  • Buy 1 Box (one moth supply) for $USD 85.00
  • Buy 2 Boxes (two month supply) for $USD 170.00

We think that the guarantee should be extended to all purchases.

Recommended By A BodyBuilding Superstar

When it comes to bodybuilding legends it doesn’t get much bigger than Robby Robinson. Known as the Black Prince, Robby was one of the greats of the Golden Era of the 1970’s. Starring along Arnold Schwarzenegger in Pumping Iron, Robbie possessed one of the most impressive physiques of all time. There is, in fact, a very good argument that Robbie possessed the greatest pair of biceps in bodybuilding history – yes, even better than Arnold!

Robby is the first man to win the Masters Mr. Olympia and is a six time category winner in the Mr. Olympia. He was also the first professional Mr. America, Mr. World and Mr. Universe.

Robby has never stopped bodybuilding. He’s a regular fixture at Gold’s Gym, Venice Beach. Now in his 70’s, Robbie is still in tremendous shape. In order to maintain his muscle mass, Robbie knows it is vital to optimize his hormones. And to ensure that he’s always got the maximum amount of testosterone coursing through his body, Robbie chooses Testofuel. Robbie has done a complete Testofuel review of his own and given it a big thumb’s up!

As you can appreciate, for a Bodybuilding legend of the caliber of Robbie Robinson to give his endorsement to a testosterone booster is a big deal.

Testofuel Robby Thrown

So, why has Robby thrown his considerable weight behind Testofuel?

Over the course of his nearly 50-year bodybuilding career, Robbie has seen it all. Knowing how important Testosterone is to the muscle building process he’s tried virtually everything that’s out there. It’s been straight out in the trenches experience that has proven to him that Testofuel really works.

Robbie recommends Testofuel to anyone who is interested in adding muscular bodyweight while keeping their body free or synthetic or illegal substances. He especially encourages older guys who are prone to losing natural ‘T’ production to start taking Testofuel in order to maintain, and even enhance, their muscle and strength levels.

Other Testimonials

Getting a Testofuel review and testimonial from a legend like Robby Robinson is pretty impressive. But, let’s face it, Robbie is a genetic freak. His bodybuilding potential is superior to you and I. So, how does Testofuel work for the average guy on the street?

The internet is full of fake testimonials, especially when it comes to packing on muscular body weight. That’s why we have been extremely discerning in combing through the masses of Testofuel testimonials online and focusing on those that appear completely 100% legitimate. The following three examples come directly from the official Testofuel website . . .

What We Don’t Like

There is certainly a lot to like about Testofuel. The 8 key ingredients are all scientifically sound and there is clinical backing to support this product’s ‘T’ enhancing effects. However, there are a couple of things that we don’t like.

Testofuel is pretty expensive. At $85 for a 30 day supply it is more expensive that most competing products on the market. This works to $2.83 per day, which is about 50 cents per day more than the average. Of course, if the product really works, and we’re pretty convinced at this stage that it REALLY does, then that extra fifty cents is a pretty good investment, right?

Something else that slightly irks us is the tendency that Roar Ambition, the people behind this product, have of limiting their guarantee and shipping policies in accordance with the quantity of product purchased. So, their 90-day guarantee only applies if you buy three or more boxes of Testofuel. The same things applies to their free shipping offer. You only get free worldwide shipping if you buy three or more boxes. We feel that these offers should apply across the board.

Who Should Take Testofuel?

If you are aged over 18 and are looking to either build or sustain your lean mass you can take Testofuel. Guys under 18, should not take Testofuel because you are still experiencing the changes associated with puberty.

Testofuel is also fantastic for older men. From the age of 30 onwards, our natural ‘T’ production drops by between 1-2% per year. The low fat diet craze of the last few decades has also lowered our testosterone levels. Low fat food is also low in testosterone. As a result, a lot of people don’t have enough of this hormone in their body.

Testofuel is the perfect solution to defeating age induced testosterone loss.

Women can and should also take Testofuel. Because it does not introduce artificial or synthetic testosterone to your system, it will not interfere with your normal hormonal balance. If you are a woman who is exercising to build more muscle and get stronger, Testofuel will be ideal to naturally enhance your body’s testosterone production to allow you to achieve your goals faster.

How Do You Take Testofuel?

Each box of Testofuel provides you with 120 capsules. You should take 4 capsules per day. That means that each box will provide you with a 30-day, or one month, supply.

You should take Testofuel for at least 2 months in order to see real, significant gains. You will definitely see some results in the first few weeks but it takes time for the levels of testosterone to build up in your system.

You do not have to cycle Testofuel as you would with prohormones. That is because Testofuel will not lower your body’s ability to naturally produce testosterone (it will, of course, do just the opposite).

Our Verdict

Testofuel verdict

Testofuel is the real deal. It contains an impressive combination of 8 of the best natural testosterone boosters on the planet. Consistent intake will result in strength and muscle gains, enhanced energy and fat loss.

Keep in mind that Testofuel will not give you the same results as you would get from using anabolic steroids. There is no testosterone booster that will do this – any that claim that they can are lying – run in the other direction!

That being said, Testofuel has proven to us that it is one of the best natural test boosters of your body’s natural testosterone production that is currently on the market.

It is pretty expensive and there are a couple of quirky things about their shipping and guarantee. But these are negated if you choose to go for their mega savings deal of 3 boxes (with another box for free) – that’s the one we recommend.

We, therefore, feel very confident in recommending Testofuel as a safe, natural and effective test booster. We recommend that you buy Testofuel!
