TestoFUEL 100 Review


This product by Amix Nutrition has an almost identical name to the market-leading testosterone booster, TestoFuel by Roar Ambition – even its bottle and box are similar.

From past experience reviewing supplements, we found that ‘copycats’ don’t do very well, or last very long – a previous TestoFuel imitation called TestoLabs went out of business only a few months after hitting the market.

So TestoFUEL 100’s bottle looks similar to market leading Testofuel, but the ingredients inside are very different – and it’s the ingredients that make or break a supplement.

Is TestoFUEL 100 worth buying, or is it a cheaper, ineffective copy of the market leading testosterone booster? Find out by reading this review.

Claimed to promote:

  • Raised testosterone levels
  • Strength
  • Endurance
  • Immune system
  • Muscle Mass
  • Recovery time

We’ll take you through the positives and negatives about TestoFUEL 100 – so you see whether it’s worth buying or not.

Take a look:

About The Company

Amix Nutrition is a brand owned by Large Life Limited – who are a company founded in the UK in 2003. Their Amix Nutrition brand sponsors mostly low-profile bodybuilders – apart from a few, such as Dennis Wolf who’s very well established.

Amix Nutrition market numerous different supplements, from this testosterone booster to protein powders. Let’s see how effective TestoFUEL 100 really is.

The Ingredients and How They Work

One positive about TestoFUEL 100 is that it doesn’t contain any proprietary blends – so we can clearly see the ingredients inside, in their exact dosages.

Also, the 5 servings per day is a good serving size; the optimal amount of servings is between 4-5, so your body is constantly topped up with key nutrients needed to improve.

But that’s where the positives end with TestoFUEL 100. The only effective ingredient in an optimal dosage inside is D-Aspartic Acid – the others are unreliable or have been under-dosed.

See for yourself:

D-Aspartic Acid (DAA)

This is one of our favorite testosterone boosting ingredients. It’s a reliable nutrient that’s proven to work.

Amix Nutrition has done well by adding an optimal dosage in TestoFUEL 100 – to get the most from DAA, you need between 2000mg-3000mg per serving.

L-Arginine Alpha Ketoglutarate 

This is the salt of the amino acid L-Arginine. It’s believed to raise nitric oxide levels, which would lead to greater muscle pumps.

But here’s the problem – no studies have shown it to work yet (i’m writing this in 2017). This makes this ingredient unreliable, which is worrying as it’s has the second largest dosage in TestoFUEL 100.

Tribulus Terrestris 

This is a herb from Ayurveda (Traditional Indian Medicine) that’s believed to boost your testosterone and libido.

While it’s shown to be capable of increasing your libido, it’s failed to improve testosterone levels in studies. Not only that, Tribulus can increase your prostate weight, which can lead to serious male health issues.

For this reason, we advise against supplementing this herb – there are many better options, without side effects, when it comes to raising your T.

Maca Root Extract 

This ingredient has shown to improve your libido, but doesn’t have any effect on your testosterone levels.

Not only that, to experience a boost in your libido, you need at least 1,500mg of Maca Root Extract – TestoFUEL 100 only contains 500mg, so it’s not likely to deliver this benefit.


Fenugreek is a great ingredient. It’s proven to raise your T levels in numerous studies, and doesn’t cause any side effects.


This is a patented mix of two ingredients – Panax Notoginseng and Astragulus Membranaceous. However, the latter ingredient doesn’t have any effect on testosterone levels.

Amix Nutrition should’ve simply added Panax Ginseng on it’s own, instead of with this mix.


Another patented ingredient, this is a mixture of botanical extracts taken from several plant sources. It’s believed to raise testosterone, and claims to have delivered this benefit in studies on rats.

However, there hasn’t been any successful human studies on Taxadrol, so it’s unreliable. Until there’s evidence that it works on humans, there’s simply no proof that it positively affects T-levels.

Side Effects

There’s only one ingredient in TestoFUEL 100 that can cause a side effect – Tribulues Terrestris. But it’s a serious potential side effect.

Take a look:

  • Increase in prostate weight (Tribulus Terrestris).

Ultimately, this can lead to serious male health issues, and isn’t a risk worth taking.

TestoFUEL 100 Review Conclusion

After analyzing TestoFUEL 100 by Amix Nutrition’s ingredients, we don’t think this testosterone booster can compete with the best on the market.

Amix Nutrition hasn’t researched very well when formulating this product – it contains only 1 key T-Boosting ingredient in an optimal dosage (D-Aspartic Acid). The other ingredients are either ineffective or have been under-dosed.

We believe that Amix Nutrition has been more concerned about marketing, by adding numerous patented ingredients inside and filling the label on their bottle with numerous brands.

Not only that, there isn’t much information on Amix Nutrition available online – leaving us asking questions, such as:

  • How long does it take for Amix Nutrition to ship TestoFUEL 100? Answer: as we don’t know where they ship from, or which postal services they use, no-one knows apart from them. We’re guessing around 1 week if you’re in the USA, as the company are based in the UK.

For this reason, we recommend you to look for a testosterone booster that contains more key T-Boosting ingredients, in optimal dosages – that don’t cause any side effects – and is from a reputable supplements company.
