TestoFuel vs Sergeant Steel

A war of attrition here as we look to TestoFuel vs Sergeant Steel to give us a look at two of the better T boosters on the market.

In fact, a quick glance and it is clear there is numerous top testosterone boosting ingredients on display, so we are excited about how this one might pan out.

This is the problem you see, for every good T booster supplement there are 20 duds. To have two that clearly have an understanding and knowledge of what makes a good product makes things very interesting.

They have gone for different approaches, the bold colors and simple yet stylish design of TestoFuel versus the masculine and obviously military-inspired design of Sergeant Steel.

How will they differ in terms of what they can do for testosterone?

A good testosterone booster should give you:

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

Since our T levels decline year on year from around the age of 30, it is important to keep them topped up

Let’s find out more about the people behind each product.

TestoFuel vs Sergeant Steel: Who Makes These Testosterone Boosters?

Roar Ambition

TestoFuel Review

Here we have the company behind TestoFuel, a UK based supplements brand.

They have an excellent reputation online with many people so impressed that they make videos confirming the results.

Roar Ambition are also impressive when it comes to customer service. With a 90-day money back guarantee, they know how to treat people who buy their products. They also review and amend their ingredients and dosages regularly to ensure their customers are getting the best possible product.

Let’s also not forget the endorsements. They have none other than former MR. Universe Robby Robinson putting his name to TestoFuel. For a man looking the way he does in his 70’s, the product can only be a good one.

They also do a fat burner called Instant Knockout. This is endorsed by UFC fighter Diego Sanchez who uses it to make weight before a bout.

Assault Labs

Here we have the company who make Sergeant Steel.

No surprise that the name is military related, especially when they have other products that follow suit in branding terms.

They have a product called Estro Strike and others such as mass builders and the like.

It’s not easy to find much company information, even a website. It seems that they sell most of their products through other sites but given that they appear on some reputable seller sites, they seem to be a legit company which is fine by us.

We would like to see a bit more in terms of money back guarantees and what they can do in terms of customer service, but at least we have the ingredients to see if this will be a decent product.

TestoFuel vs Sergeant Steel Ingredients

The good news is that neither of these testosterone boosters use proprietary blends.

This means we get to take a good look at the significant ingredients and all the dosages are made available.

The serving schedule for TestoFuel is exactly the kind we like. They suggest taking it 3-4 times a day. This means the benefits are spread out throughout. That is the problem with Sergeant Steel…

Not only is 5 capsules twice a day, a lot to take on in one go, but the benefits are unlikely to continue all day with Sergeant Steel.

Either way, we can take a good look at what goes into these T boosters.

Mutual Ingredients

Vitamin D

Among the best testosterone boosting ingredients.

This is because low levels of Vitamin D are linked to low testosterone, keeping this topped up is paramount.

Our bodies actually create their own Vitamin D when our skin is exposed to direct sunlight. The problem is that many of us are deficient in this ingredient, making it important to supplement it into our diets.

The 5,000 IU included in TestoFuel is an optimal dosage. The 3,000 IU in Sergeant Steel is a bit below what we like to consider optimal.


Among the best once again, in fact, our bodies cannot create more testosterone without it.

Popular in booster supplements because it works on different levels, it is one that stops your body from depleting its T levels during an intense workout. This leaves more in your system for later.

It is also good for stimulating the luteinizing hormone. This communicates with the testes to create and release more testosterone.

The 10 mg in TestoFuel is optimal and consider the fact that they also include Oyster Extract which has plenty of Zinc in it then it is a pretty potent product when it comes to Zinc. The 15 mg in Sergeant Steel is a good amount also.


Another excellent T booster for many reasons.

This ingredient is known to stop the SHBG (Sex Hormone Binding Globulin) from being so effective. This is good news for your testosterone since it binds your T, making it unable to be used.

It’s not done yet though, it also helps you to deal with oxidative stress. This means you can better cope with the effects of exercise as well as aging.

Let’s not forget as well that it is also thought to be good for helping you to build muscle.

Unfortunately the 50 mg in Sergeant Steel is not really enough to get us excited, the Testofuel dosage of 200 mg is much more like it.

D-Aspartic Acid

Both products here have really done their research.

Another great ingredient, this time because it once again stimulates the luteinizing hormone, but also supports sperm count.

It also triggers the Human Growth Hormone so there is a lot of good going on. No wonder it is often tipped as one of the best T boosting ingredients around.

The 2,300 mg in TestoFuel is an optimal dosage, as is the 3,000 mg in Sergeant Steel.


Another good inclusion from both.

This popular spice is included in many T boosters because of its libido enhancing capabilities.

The fact that it is also good for supporting insulin levels means your testosterone will also benefit.

Individual Ingredients


Vitamin B6

Another one of the best T boosting ingredients.

This is great because it lowers your estrogen levels, which means there is more room for testosterone to thrive.

It can even enhance your mood and ensure you put the food that you consume to better use.

A great ingredient for your muscles and overall workouts. Also, optimally dosed at 5 mg.


A good inclusion here as it is known to aid the body’s production of testosterone.

It even reduces prolactin levels. This is exactly what you want – too much prolactin is bad news for your T.

Sergeant Steel


A solid ingredient here and as it lowers estrogen and raises your T, the kind of thing we expect and like to see.

The 5 mg will be enough for it to be a welcomed inclusion.


An unfortunate inclusion. Since it does nothing for testosterone levels it is taking up valuable space.

A rundown of some of the other ingredients reveals that there are others that follow this pattern.

TestoFuel vs Sergeant Steel Side Effects

Well, this is where both products do well, neither contains anything that should cause any side effects.

No proprietary blends make it easier to stand by both products in terms of safety. As always we recommend that you check the label, in case of allergies.

It was a pretty close contest when it came to a lot of the ingredients. There are a lot of similarities and both have included some brilliant T booster ingredients.
