Prime Male vs Sergeant Steel

With so many of us in need of a T boost, it is no wonder we have been asked to provide a Prime Male vs Sergent Steel review.

So, here it is, putting two of the better testosterone boosters on the market against one another for your entertainment. The fact is, when we are around the age of 30, our T levels decline year on year, and do so for the rest of our lives.

A worrying statistic, but only for those who haven’t yet found an effective testosterone boosting supplement. We get it though, it is a minefield out there with so many ineffective supplements that look the part on the outside, just not on the inside.

Speaking of minefields, we have one product that leans towards a military theme in Sergeant Steel, and another that has placed itself in the market for the mature demographic.

This means we should be in for an interesting comparison today. As long as these products give you the following:

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

We consider this to be a minimum requirement really, and the better products will usually give us something a bit more. Time to see if these testosterone boosters have what it takes.

Prime Male vs Sergeant Steel: Who Makes These Testosterone Boosters?


Prime Male Testosterone Booster Review

This UK based company are the people behind Prime Male.

With years of experience behind them, they have applied it to this product. They make all their supplements in FDA registered facilities to GMP standard they do all the basics right.

They also have a generous 60-day money back guarantee. These are the sort of things we like to see. Too many companies offer 30 days or even nothing. Since it often takes around 4-5 weeks for most people to really notice a difference, this isn’t enough.

All their products are made to GMP standard and in FDA registered facilities, good to know they do everything right.

It is from these facilities that they ship their 100% natural products worldwide.

Assault Labs

Read our full Sergeant Steel review

Like we said, Sergeant Steel is made by the military macho brand Assault Labs. They claim this product is a military grade T boosting product!

This continues with their other products such as Estro Strike!

You won’t find it easy to get a lot of company information on them. They don’t even seem to have a website. Instead, they sell their products through online sellers, all of which seem legit as far as we can see so there doesn’t appear to be any reason to worry.

The problem is, we can’t find information such as money back guarantees or when they were founded.

Well, we might not know a lot about them, but we still have what we need – the ingredients.

Prime Male vs Sergeant Steel Ingredients

This is where we can start to find out what they are really about.

The first impressions are good – neither use proprietary blends. This means we get to take a good look at the dosages and ingredient selection.

The suggested serving from Sergeant Steel is not ht we prefer though. We like a testosterone booster that can be taken 3-4 times a day to spread out the benefits.

They advise taking 5 capsules twice a day. Not only is this a lot each time, but it means you are unlikely to get the T boosting benefits all day.

Still, let’s carry on.

Mutual Ingredients

Vitamin D

You only really see this in the better T boosters.

Low levels of Vitamin D have been linked to low testosterone, since many of us are deficient, supplementing it is really important.

Our bodies actually create their own Vitamin D when our skin is exposed to direct sunlight. Since many of us aren’t getting enough of this ingredient, it is clear we are lacking some rays!

The 5,000 IU in Prime Male is an optimal dosage that will do great things for your testosterone. The 3,000 IU in Sergeant Steel is below par really.

Probably the best ingredient in this Prime Male vs Sergeant Steel review.


Another brilliant T booster here.

Zinc is great because not only is it super important it works in lots of different ways.

Our bodies cannot create more testosterone without it, hence its significance.

More than this, it is also good for maintaining your T levels that would otherwise deplete significantly during intense exercise.

Think that’s it? Nope, it is also great for stimulating the luteinizing hormone, this communicates with the testes to create and release more T.

The 30 mg in Prime Male is an optimal dosage, as is the 15 mg in Sergeant Steel.


A great ingredient once again.

Magnesium is so good because stops the Sex Hormone Binding Globulin form being as effective. Because it binds your T up, you cannot use it. Anything that stops this from happening means there will be more T in your body.

It’s also a good ingredient for dealing with oxidative stress. This is when aging and exercise can affect you, magnesium reduces the effect.

Thee are nice and everything, but what you really want to know is that it helps you build muscle, which it does.

The problem for Sergeant Steel is that they have only included 50 mg, not the best dosage, especially since Prime Male has 100 mg in theirs.

D-Aspartic Acid

Brilliant inclusion once again.

You will find this in more and more T boosters now that so many people are talking it up.

It is another that stimulates the luteinizing hormone, as well as increasing sperm count. Not to forget that it also triggers the Human Growth Hormone, making it a great all-rounder.

The  1,600 mg in Prime Male will still give you a boost but is a little low compared to the 3,000 mg in Sergeant Steel.


An undervalued T booster in some quarters it is gaining a reputation as a top ingredient now

It is good for limiting the SHBGs effectiveness as well as boosting T levels in general. There is some support for its ability to enhance prostate health, although this is based on little evidence so far.

The 4 mg included in both products is all you need to get the benefits.


Another excellent inclusion here and this childhood pest for making your ankles itch has turned out to be a good testosterone booster.

Another that lowers SHBG levels, it also inhibits aromatase which stops your body from turning testosterone into estrogen. That would be the opposite of what we want here!

Individual Ingredients

Prime Male

Vitamin B6

A top T booster it is another that is amongst the very best.

It is great because it lowers estrogen levels, this frees up room for testosterone. It is even known to be a mood enhancer and puts whatever food you consume to more effective use.

Sergeant Steel


This is representative of few of the other ingredient included in Sergent Steel.

It is ineffective in terms of testosterone boosting so it doesn’t have a place in this product really.

Prime Male vs Sergeant Steel Side Effects

The good news is, another product has anything untoward.

The dosages are within optimal or sensible ranges and there are no proprietary blends to worry about. Check the label as always for allergies of course.
