It can be so frustrating...

You lift the iron, you chug your protein, you shovel down the latest hyped-up supplements...

Let's face it, you don't go to the gym, sweat bullets and eat till you're sick, just for the fun of it. You want the results, in fact you actually long for them, but you don't want big muscles just for the sake of it.

It's not actually about the muscles themselves, it's about how they make you feel and of course, how they make you look...

Unfortunately, as you've probably found out for yourself, it seems like there's something missing and whether you know it or not, the missing link is testosterone.

If you want to build an impressive physique, do not overlook the massive importance of this vital muscle building hormone.

Newsflash. No Testosterone...
No muscle growth.

You've tried countless vitamins, supplements, pills and potions, used every workout routine in the book and still... you just can't get those muscles to grow anywhere near as fast, or as big as you'd like.

Without sufficient testosterone to trigger real, heavyweight muscle growth, you are destined to continue make feeble gains, no matter how hard you train or how much you eat.

Think of it like the foundations of your home.
Without it, you wouldn't even have your home

Testosterone is the biological equivalent. It's an extremely essential hormone because it's the 'foundation' of many major biological functions.

Testosterone increases muscle mass
Testosterone works its muscle-building magic by increasing muscle protein synthesis.

Testosterone decreases body fat
As your testosterone levels decrease, your body’s ability to regulate fat metabolism, insulin and glucose also decreases, causing fat to accumulate.

To make matters worse more stored fat can push testosterone levels even lower, because body fat produces the enzyme aromatase, which can convert testosterone to estradiol, the predominant estrogen. Higher testosterone levels mean lower estrogen levels, which are essential for real muscle growth. Also, TestoFuel contains Oyster Extract which is extremely high in zinc, known to lower estrogen levels in the body.

Testosterone can boost competitiveness
Testosterone helps to boost our drive to win, as it's linked with our desire for power and status (Dabbs & Dabbs 2000). The more driven you are, the more motivated you'll be to train.

As if that wasn't enough, testosterone also helps the release of growth hormone, another incredibly important trigger for muscle growth. So you are effectively getting a double dose of growth when you raise your testosterone levels.

Think about it...
The majority of steroids are testosterone based.

That's what steroids do...

they raise your testosterone levels. And let's face it, if you could only take one 'supplement' to help you pack on the muscle, you'd probably choose steroids because they are so powerful.

But of course, steroids come at a price. They're hard to source safely, they're expensive and have many serious health risks. Not only that, with all the fake testosterone out there, could you say for certain exactly where it had come from? Also, when you use synthetic testosterone (steroids), it can force your body to produce less of its own.

So steroids are certainly not the route to take to your perfect physique.

Obviously then, it makes much more sense to increase your testosterone levels in a powerful yet natural way.

And thanks to the fact that scientists are finally discovering the connection between certain nutrients and a boost in testosterone production, this is now so much easier.

Taking individual vitamins, minerals and co-enzymes etc, is all well and good, but you need 'compound' nutrition first, such as ensuring your body has the nutrients it needs for maximum testosterone production.

Increase your testosterone without harmful steroids and feel the growth!

Your muscles
need testosterone

Way before they need the individual,
latest hyped up nutrients

In case you're not convinced about that and still think you need 'Co-Enzyme 365/32' (Not real, but they always seem to have ridiculously complex names) more than testosterone, think about this:

People were packing on slabs of muscle way before the invention of the latest secret ninja nutrients, as long as their testosterone levels were sufficient!

Think of the legends from the 1970's such as Arnold Schwarzenegger, Frank Zane, Lou Ferrigno (The Incredible Hulk) and so many more with herculean physiques. Did they have $50 a pop micro nutrients? No. They concentrated on simple, sensible nutrition, lots of protein, along with a focus on raising their testosterone levels and built some of the most famous and impressive physiques in history.

Raise your testosterone level and keep it raised, and the muscle can pile on, it really is that simple. And one of the main reasons for this is that testosterone increases protein synthesis.

TestoFuel contains all natural ingredients including:

  • D-Aspartic Acid
  • Vitamin D
  • Oyster Extract

The bricks and mortar of muscles


Ok, so you're probably already aware that protein is essential to muscle growth.

Muscles need amino acids to build new fibres and that's where protein comes in, as it's made of amino acids. But there can be a huge difference in the amount of protein you consume and the amount of protein your body can actually use.

The more protein your body can use, the bigger and faster your muscles will grow and because testosterone helps to increase protein synthesis, it means more of the protein you consume will be used to build muscle.

Testosterone binds to androgen receptors in the muscle cells, stimulating protein synthesis and causing muscle growth. Not only that but it also helps to prevent muscle tissue breakdown, known as catabolism.

So here's the simple solution...increase your testosterone levels and you'll finally see the muscle piling on.

So what's the best way to do that? The powerful, yet natural and safe testosterone releasing formula, TestoFuel.

So what makes
TestoFuel so powerful?

Let's have a look at the 3 main ingredients:

All natural ingredients badge

D-Aspartic Acid

This amino acid promotes muscle mass by regulating two very important hormones – testosterone and growth hormone.

It stimulates the part of your brain that is responsible for releasing luteinizing hormone. More of this means more testosterone release.

There are a number of studies showing D-AA can elevate anabolic hormone levels by as much as 45% in 13 days and 60% over 90 days[1].

1. D’Aniello, S et al. D-aspartate, a key element for the improvement of sperm quality. Adv. Sex. Med. 2012; 2: 47–53


Vitamin D isn’t just an important vitamin – it’s considered the sixth steroid hormone due to its ability to support anabolic hormones such as testosterone.

This is an extensively researched nutrient. It is a kick-start to accelerate testosterone levels, making it a must have in any good male hormone complex.

Studies show that not only are higher doses of vitamin D safe, they help to boost strength, muscle mass and metabolic health too[2].

2. Ogan, D et al. Vitamin D and the athlete: risks, recommendations, and benefits. Nutrients. 2013; 5(6): 1856-1868


Oysters are well known for their libido-boosting, aphrodisiac powers.

They are one of the best sources of zinc you’ll find – a potent mineral that has been found to boost testosterone in a number of clinical trials[3].

Not only will this food extract boost anabolic hormone levels; it’ll inhibit estrogen too, meaning more muscles, less belly fat and no more man boobs.

I have been taking Testofuel for about two months now. Before testofuel I would spend hours at the gym day after day, striving to get results that just wouldn't come. After a few months at the gym I started to get really down, and began feeling as though I would never make any progress. I was still just as skinny as I had always been. During that time period I had tried numerous workout supplements and different types of testosterone boosters, with very minimal effects.

That's when I started searching online for any information as to why I couldn't build, and that's when I found Testofuel. I saw a lot of positive reviews and commentaries about it so I figured why not, I got nothing to lose - and boy was I glad I gave it a shot. Read the full testimonial here...

Increase testosterone

Boost natural growth and repair

Boosting your T-levels with TestoFuel also fires up your body’s natural production of other hormones. You’ll experience not only muscle growth, but also in anti-ageing cell repair and metabolism, without the need for dangerous synthetic steroids.
