Bottom Line

Testofuel is a testosterone booster that's been making waves in the market.

It's got some pretty big promises, but does it really deliver?

Let's break it down.

TestoFuel comes with a handful of ingredients that, on the surface, look pretty solid.

But here's the kicker: the dosages just don't stack up.

They're significantly lower than what you'd ideally want for a testosterone booster.

Now, you might be thinking, "Well, it's got some good stuff in it, so it can't be all bad, right?"

But here's the thing: there are other options out there that pack a bigger punch.

Take Enhance, for example.

It's currently leading the pack as the top testosterone booster on the market. And honestly, we haven't come across anything that can top it yet.

So, while TestoFuel has made a name for itself with its marketing, the reality is that it falls short where it really matters: the ingredients and their dosages.

Bottom line? You might want to consider looking elsewhere for your testosterone-boosting needs.

I’m sure you’ll agree that testosterone is important…

You want to build muscle and get stronger but without healthy testosterone levels, it is a mission impossible.

You’ve heard of testosterone boosters and you’ve probably ran into this specific one more than a few times.

The one we’ll dig into is TestoFuel and it has set off quite a few sites that promise this to be one of the best test boosters ever.

This is the same company that makes Instant Knockout and it’s been knocked out several times as being an overpriced, underdosed but yet it’s still a very popular fat burner.

People that push Instant Knockout as being a great fat burner are being paid $18 per bottle and the rewards are similar for TestoFuel.

What you’ll learn today will help you make better decisions for supplements so you don’t get ripped off with overly marketed and hyped products…

If you want to jump straight to our recommendation it's that you should skip this test booster and go for Enhance. 

What Is Testofuel?

TestoFuel is a capsule based supplement designed to help build muscle.

It does this by encouraging the body to produce more testosterone naturally.

Testosterone is a male growth hormone which is vital for muscle growth and strength development.

As we age we naturally lose testosterone.

TestoFuel is designed for both athletes and sedentary people as a means of boosting their ‘T’ levels.


An immediate plus for this product is that it is not a proprietary blend.

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 contains 8 ingredients that claims to be scientifically proven to enhance natural testosterone production.

Let’s drill down on each one to see whether they stack up.

D-Aspartic Acid (2.3g)

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 is 2300 mg of D-Aspartic Acid in every capsule of Testofuel (4).

Magnesium (200mg)

Magnesium is a little appreciated but highly effective booster of testosterone.

It acts to speed up the metabolism, allowing you to absorb fats and proteins more efficiently.

It can also free up testosterone that is bound to sex hormone binding globulin (SHBG) (5).

Vitamins B6, D and K2 work together to stimulate testosterone receptors and improve the absorption of zinc and magnesium (7).

However, taking Vitamin D every day can be a problem due to the fact that it may cause excessive levels of calcium in your blood.

This can, in turn, result in nausea, vomiting and headaches.

It should be noted that the side effects have been noted by a number of Testofuel users.

Siberian Ginseng (100mg)

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.

While there have as yet been no conclusive studies showing that ginseng directly boosts testosterone levels, it has been shown that Siberian Ginseng can enhance the levels of two other key hormones which are vital to testosterone release . . .

  • Adrenocorticotropic Hormone (ACTH)
  • Adrenaline

TestoFuel contains 100mg of Siberian Ginseng (2).

However, there is a downside to taking ginseng.

It has been shown to cause a number of undesirable side effects, including nausea, high blood pressure, increased heart rate and, most commonly, insomnia.

According to WEbMD, ginseng may be unsafe when taken orally.

Fenugreek (100mg)

Fenugreek is a herb that is a popular ingredient in many curries.

It is also promoted as a booster of testosterone as well as a libido enhancer (3).

However, there have not been any conclusive studies showing the link between this herb and higher levels of testosterone.

It is also associated with such side effects as gas, bloating, stomach upset and low blood sugar levels.

There are 100 mg of Fenugreek in TestoFuel.

Oyster Extract (100mg)

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 healthy testosterone levels and oysters are one of the best ways to get it.

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 (1).

Oyster extract is a problem for people who are allergic to seafood.

If that’s you, then you can forget about taking TestoFuel.

There are 100 mg of oyster extract in TestoFuel.


The ingredients list that makes up TestoFuel is nice to see on paper.

However, it is the combined effectiveness of the ingredients on the bodies of real users that counts.

Those results are decidedly mixed.

A number of users reported that they did feel an immediate increase in energy when they started using TestoFuel, but that this effect soon wore off and, from then onwards, they didn’t feel any noticeable effect from using the supplement.

Here is a typical comment in this regard . . .

“First time I tried TestoFuel it seemed to me that I was full of energy and thought it would be always like that if I take it. But the effect was temporary and after a short period of time I didn't feel anything. I think there is a high price to pay for such short-term results”

You’ll need to take the product for at least a couple of weeks to realize noticeable benefits in terms of testosterone levels within the body.

By then the constituent ingredients will have saturated your system and built up to quantities sufficient to have an anabolic effect on your body.

The key to success with this, as with all testosterone boosters, 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 designed to provide 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.

Yet, as stated earlier, a large number of users reported no noticeable gains in terms of either energy or libido.


The recommended dosage is four tablets per day.

Each container contains 120 tablets.

Tablets can be taken at any time of the day as it won't affect sleep or anything.

They recommend taking this supplement even on your non-training days.

This is great for those who train after a long day at work.

TestoFuel claims to provide that boost to get you into the gym and hitting the weights.

Underdosed Label

  1. D-aspartic acid (D-AA): Testofuel contains 2,000 mg, while the recommended dosage is between 2,000 to 3,000 mg per day according to So, it's within the recommended range.

  2. Vitamin D: Testofuel contains 100 mcg (4,000 IU), while the recommended dosage is between 10-20 mcg (400-800 IU) per day, but it can go up to 100 mcg (4,000 IU) for adults according to Healthline. So, it's at the upper limit of the recommended range.

  3. Oyster Extract: Testofuel contains 100 mg. There's no standard recommended dosage for oyster extract, but it's generally considered safe in moderate amounts as per BulkSupplements.

  4. Ginseng: Testofuel contains 100 mg. The recommended dosage varies depending on the type of ginseng, but it's generally between 200 to 400 mg per day according to AAFP. So, it's underdosed.

  5. Fenugreek: Testofuel contains 50 mg, while the recommended dosage is between 500 to 600 mg per day according to WebMD. So, it's significantly underdosed.

  6. Maca: Testofuel contains 180 mg. The recommended dosage is between 1,500 to 3,000 mg per day. So, it's significantly underdosed.

  7. Magnesium: Testofuel contains 70 mg, while the recommended dosage is between 310 to 420 mg per day for adults according to Healthline. So, it's underdosed.

  8. Boron: Testofuel contains 8 mg. The safe upper limit for adults is 20 mg per day according to Verywell Health and WebMD. So, it's within the safe range.

  9. Zinc: Testofuel contains 10 mg, while the recommended dosage is between 8 to 11 mg per day for adults according to Mayo Clinic. So, it's within the recommended range.

  10. Vitamin D3: Testofuel contains 100 mcg (4,000 IU), which is the same as the Vitamin D mentioned above.

  11. Vitamin K2: Testofuel contains 18 mcg. The adequate intake for adults is between 90 to 120 mcg per day. So, it's underdosed.

So while some ingredients in Testofuel are within the recommended dosage range, several key ingredients like ginseng, fenugreek, maca, magnesium, and vitamin K2 are underdosed.

This could potentially affect the overall effectiveness of the product.

It's important to note that the effectiveness of a supplement also depends on the individual's body, lifestyle, and diet.

Therefore, it's always recommended to consult with a healthcare provider before starting any new supplement regimen.

Side Effects

TestoFuel is made from all natural ingredients.

And really there isn't any side effects because none of the ingredients are dosed at clinical dosages. 

Everything is underdosed, even D-Aspartic Acid. 

And another side effect to note is a lighter wallet, without any benefits for increasing performance. 

The profit margins for this kind of product is huge as the dosages are so small that it would probably only cost $10 to make this. 

If you are currently taking any medication, you should consult your doctor before taking TestoFuel.

Testofuel Stack

If you look at what Testofuel recommends for stacking, they recommend using a pre workout and fat burner alongside it. 

While they are correct, the ones that they recommend is also underdosed. 

There's no secret to what should be used in pre workouts and what ingredients are optimal. 

That's why we recommend Wrecked by Huge Supplements and checking out this fat burner list here. 

The best muscle building stacks can be found in this list. 

Purchasing Information

You can only buy TestoFuel through the product’s official website.

There are three purchasing options:

  • One Month Supply (120 capsules) = $69.00 USD + $7.95 shipping
  • Two Month Supply (240 capsules) = $138.00 USD (free shipping worldwide)
  • Four Month Supply (480 capsules) = $219.00 USD (free worldwide shipping plus a free t-shirt).

A 2 month supply of TestoFuel is available for $138.00. This equates to $2.30 per day.

This makes testoFuel an expensive supplement to take for the purpose of looking your testosterone levels.

You should be looking to pay around half of that amount and even then it should be for a properly dosed testosterone booster.

Check out this alternative and avoid Testofuel.

With the range of side effects that have been reported and the rather exorbitant price tag, we simply cannot give this one a thumbs up.
