Testo Fusion Review

Shiny objects are enticing, right? Well, our Testo Fusion review brings us a product that looks the part, but does it have what it takes to make it onto our top recommended testosterone boosters list?

In order to impress it is going to need to be thorough. Only proven ingredients at optimal dosages will help it to prevail here.

This is a cheap option for sure, but this doesn’t always mean it is better, plus the supply will only last you just over two weeks but we’ll get onto that later.

Because our T levels drop year on year from around the age of 30, it is important to find a supplement that works.

What does it have to do to impress us? Well, like any T booster it needs to give us the following:

  • More strength
  • Increased energy
  • Enhanced libido
  • Elevated mood

If it can’t do all of the above then it isn’t worth your time. Let’s find out a bit more about the people behind this T booster.

Testo Fusion Review: Who Makes Testo Fusion?Testo Fusion review testosterone booster by Reflex Nutrition

Reflex Nutrition is the brand behind this product.

Based in the UK they have been in operation since 1996 so they have enough experience to deliver a good supplement you would think.

Their factory is based in the UK as well and they have a money back guarantee. This is good to see and although there isn’t a specific amount of days to return it within, it seems legit.

In terms of products, they have a wide range available that include everything from amino acids to plant-based products.They even have some specific products tailored to certain sports.

Their ambassador’s page include weightlifters and even a professional football team in Brighton and Hove Albion so their products have a good industry reach.

Now we can really get a good look at this product and the initial signs are good, there are no proprietary blends here. This means we get to take a proper look at the dosages to see how effective this product is.

The suggested serving is not ideal though. They advise taking 3 capsules twice a day. Not only is this a lot at once it also means you won’t feel the benefit all day long. We prefer to see a supplement we can take 3-4 times a day to spread out the T.

Each comes with 90 capsules and if you’re taking 6 a day it will only last you 15 days – not the month’s supply they claim for some reason.

Vitamin D3

One of the better T booster ingredients and found in many of our top recommended testosterone boosters.

This is because it is thought that low levels of D3 are linked to low testosterone so keeping it topped up is important.

Our bodies actually create their own D3 when our skin is exposed to direct sunlight. The problem is many of us are deficient meaning our lifestyles mean we aren’t getting enough rays.

The 1,200 IU in Testo Fusion isn’t enough to give us what we need considering the minimum you require to get things moving is over 3,000 IU.

Vitamin B6

Another great inclusion here.

This time it is because helps to stop your body from producing estrogen which in turn prevents it from being so effective. Since estrogen is a known killer of T and actually takes space that your T needs to thrive, limiting it is a great trait for any T booster.

It stops the Sex Hormone Binding Globulin from being effective which really ties up your T and it is even thought that low levels of B6 are linked to low testosterone.

10 mg is a good dosage from Testo Fusion.


Another good ingredient and another that helps to stop SHBG from being as effective. This will free up your T so you can put it to use.

Since our daily tolerance is around 450 mg and we do get some of this in our diet, the 150 mg is a decent dosage, although a little on the low side for some.


Another excellent ingredient and another found in most of our top recommended testosterone boosters.

The fact is, our bodies cannot create more testosterone without it.

It is great for stimulating the luteinizing hormone. This communicates with the testes to create and release more testosterone. Zinc even stops your body from depleting T levels so much during intense workouts.

The 30 mg included here will do a good job of getting your T levels up. One of the best ingredients in this Testo Fusion review.


We can see why they have included Copper in some ways but it is a strange inclusion, to be honest.

It is thought that too much Zinc can cause a deficiency in Copper. Although this would be dangerous, there isn’t enough in here to worry you. Examine.com comment on the fact that there is little evidence concerning its usefulness as a supplement.

The space this takes up could have been used for a better ingredient.


This is a good idea for a T booster.

There have been many studies on this ingredient and this is one that stops the Sex Hormone Binding Globulin from being as effective. By restricting estrogen and increasing testosterone it is the kind of ingredient you need.

At 10 mg it is a sensible but optimal dosage for getting the benefits.


This traditional medicinal ingredient is a famous aphrodisiac and will do great things for your libido.

Another popular ingredient it has other uses too. For your testosterone, this is good and controlling insulin levels and stopping them from spiking. This, in turn, is good news for stabilizing T levels so it is a clever ingredient.

750 mg is a large amount of an ingredient you can get into your diet easily but this amount will do no harm, only good.


This is good for stamina if you’re in a much older demographic.

Studies don’t seem to reflect the same benefits for younger users. In terms of testosterone, it does help to protect the user against oxidative stress. This is good news for testosterone as stress is a known enemy of your T.

The 2,000 mg in this product is on the higher end of the scale but will bring you the benefits. We just believe it should have been spent on better ingredients as it takes up a lot of space.

Testo Fusion Review: Testo Fusion Side Effects

The good thing about this product is there doesn’t appear to be anything in there that should concern the user. The dosages are relatively sensible and there aren’t any worrying ingredients.

As always, we advise that you check the label if you have any allergies.

Testo Fusion Review Pros and Cons


  • Some effective ingredients
  • Some good dosages
  • No proprietary blends


  • Not available in a lot of countries
  • D3 underdosed
  • Serving schedule not ideal

Testo Fusion Review Conclusion

Although this has some decent ingredients there is plenty of room for improvement.

We liked the fact that it includes a decent amount of Fenugreek, Boron, and Zinc as these are some good ingredients that will really boost your testosterone.

The main problem is in the lack of Vitamin D3, the dosage included could be a lot higher and isn’t enough to really have an impact. There is also the fact that there is no D-Aspartic Acid, one of the most effective testosterone boosters that the best products include.

The fact that it is safe really works in its favor and we also like that they do not use proprietary blends.

Another problem, however, was the serving schedule. It is far more beneficial if the product can be taken multiple times a day to really spread the benefits out.

This isn’t a product we recommend because there are far more effective options on the market and at CLM, we don’t recommend anything but the best.
