My Assault Labs Sergeant Steel Review

First Look

Natural testosterone boosters can be an effective way to elevate natural testosterone levels to increase lean muscle mass.

This is the Sergeant Steel by Assault Labs review. SIR!

This is called a ‘military grade testosterone activator’.

Marketing departments love to use ‘military grade’ when advertising their manly products like pick up trucks and clothing ranges.

My memories of military grade equipment were itchy and uncomfortable uniforms with terrible beds. Or extremely bumpy, noisy and uncomfortable vehicles.

So in that respect, I am not sure I want something I am about to put in my body to be quite as sleep deprivating.

But this sort of marketing works to many people.

There’s a muscular military guy on the front, however, to me it does remind me of the plastic toy soldier kits you can get as a child which come in a little bag.

This is also advertised as the most powerful testosterone booster as well which is some claim.

However, I do hope their’s some truth to this as I sit in front of my PC feeling hungover and certainly not strong nor teeming with testosterone coursing through my veins.

I feel like a slob…

Can the Sergeant Steel testosterone booster hit the mark? Let’s look at their background…

Who Are Assault Labs?

I have researched who Assault Labs are, and while I know they have a few different products on offer I cannot find any further information.

A mystery.

However, you can buy Sergeant Steel from Amazon. Yet we have not found Sergeant Steel on GNC or any other popular retailers.

Initial Summary

PROS – 4 proven testosterone booster ingredients and its cheap

CONS – there’s 4 unproven ingredients & maca can act as an estrogen

Ingredients: The Science

This test booster is seemingly loaded with ingredients, so it will be interesting just to see what science stacks up and if more means better…

– Tribulus

The myth is that tribulus has strong anabolic effects. Yes, a plant that is all over the world has anabolic benefits…so we are told.

To make matters worse lots and lots of brands that sell supplements stick project this fallacy in order to promote their products.

The problem is that people believe it, why wouldn’t you trust a large health and nutrition brand? Note that every company now projects themselves as a health and nutrition brand rather than a bodybuilding supps firm?

That’s because bodybuilding isn’t as trustworthy as health and nutrition…

However, I digress, but the point is while every supps company is pushing tribulus it didn’t take me much effort to find reliable scientific sources that contradict the notion that tribulus acts like a powerful steroids.

It did not take me more than 10 minutes to find university studies that state tribulus does not alter testosterone levels at all. [1] [2]

– Primavie (Shilajit Extract)

Shilajit has been used for years by sherpas who live around the Himalayas, so much so that they include it as part of their diet.

There’s good reason for this because scientific studies point towards several benefits at preventing diseases. The most potential seems to be preventing or treating Alzheimer’s.

In terms of testosterone, there’s been some great results in men who are infertile, although there’s been no results regarding fertile men. Sperm quality also improved in men who are infertile.

One area of concern is the contamination of shilajit, this has driven Canada to ban all imports. [3]

– Fenugreek Seed (Trigonella Foenum-Graecum)

Fenugreek is high doses of over 500mg has anabolic benefits, while preventing the conversion of testosterone to estrogen.

Fenugreek is also an effective fat burner. [4]

– Nettle Root

Good for reducing inflammation and an enlarged prostate, it can increase testosterone levels but has more effect on preventing estrogens being formed from testosterone.

You can read more here. [5]

– BioPerine

Bioperine has no effect on testosterone levels or fat mass for that matter.

However, bioperine facilitates the absorption rate of the other nutrients.

This is found in Instant Knockout. [6]

– Calcium

Studies have confirmed that by supplementing calcium in conjunction with a training program will increase testosterone levels.

However, a recent study has warned against continued calcium supplementation due to the increased risk of a heart attack. [7] [8]

– Longjack (Eurycoma Longifolia, TongKat Ali)

Longjack can increase testosterone, however, this is usually because it has anti-stress benefits.

It can reduce general stresses that would otherwise harm natural testosterone production according to the research. [9]

– Ashwagandha (Withania Somnifera)

There’s some thin evidence currently available that points towards Ashwagandha being able to increase natural testosterone levels in men.

The best doses required for optimal use is over 3000mg. Although it is reported that lower dose of 300mg can be effective at reducing stress and anxiety but is much cheaper.

This test booster contains just over 300mg, so they’ve really decided on economy over results. [10]

– Abieta-8 11 13-trien-18-oic acid (DEHYDROABIETIC ACID DHAA, Pine Rosin Extract)

There is very little information regarding DHAA, what we have discovered is that it has anti-estrogen properties but this is only in fish.

Other research has demonstrated that there are anti-inflammatory benefits and anti-oxidants, this can help prevent a suppression of testosterone production. [11] [12]

– D-Aspartate (DAA)

D-Aspartic Acid is one of the key testosterone stimulating ingredients that are found in the best test booster supplements.

While it does increase testosterone in studies it also has no estrogenic effects, for best results a daily dose of 2000-3000mg is required daily. [13]

– Velvet Bean (Macuna Pruriens)

Mucuna’s main benefit is that is can reduce levels of prolactin which actively lowers the levels of natural testosterone production.

It is effective to reduce cortisol levels – high stress levels can harm testosterone production. [14]

– Boron

Boron is helps reduce inflammation. Inflammation is the root cause of many chronic diseases that can have a very bad impact on your overall health.

Studies have also concluded that boron can increase testosterone levels. [15]

– Maca Root

Maca can improve libido, however, it has not been concluded that it can increase testosterone or have any hormonal effects at all regardless of gender. [16]

– Magnesium

Research into magnesium supplementation demonstrates that it is able to increase testosterone production in men. [17]

– Vitamin D

Vitamin D is crucial to human existence. We tend to get most of it from exposure to sunlight but it is available from eggs and fish.

Vit D has many health benefits that range from bone strengthening to cognitive function.

For us, in this instance we are interested in its test boosting capabilities which have been proven.

Many health authorities advise that we get at least 1000-2000iu per day.

This provides 1500iu so is slap bang in the middle, but other supplements include 5000iu. [18]

– Zinc

Zinc is an essential mineral to help increase testosterone levels.

In very high doses, zinc can act as an aromatase inhibitor and reduce estrogen levels. It is also a potent antioxidant and can provide benefits for prostate issues. [19]

How to take Sergeant Steel

You are not going to believe this, but we are ~~instructed~~ ordered to take 5 capsules twice daily.

That’s a whopping 10 pills a day!

However, all of these capsules amount to just over 6040mg daily.

That is quite a large dose. You’ll be sick of taking all of those pills after day number 3!

Pros

This is a large daily dose offered by Sergeant Steel which looks great.

Especially when we see the old war dogs D-Aspartic Acid and D3 present and reporting for duty.

Let’s not overlook the qualities of Magnesium, Zinc, Fenugreek, Boron, Bioperine and Calcium either which are all proven to help increase testosterone levels or at least, in the case of Bioperine, assist with bio-availability.

However, with all of those ingredients totaled up we then see a sharp decrease in the effective ingredients. Only 3661.03mg is now available for to increase testosterone levels.

Yet, that is still a large amount though and spread across just 7 ingredients which is good.

Cons

It is such as shame to see that of the 16 ingredients available here, only 7 are proven to have any benefit when it comes to increasing testosterone levels.

However, if taken on a regular basis, one of those ingredients, namely Calcium, can cause cardiovascular issues as Calcium can create artery plaque which then decreases the diameter of your arteries making it harder for your heart to pump blood.

10 pills does seem a bit excessive, plus we are ordered to take 5 in two sittings when having them spread out across the day would be more beneficial.

Therefore of the 16, 9 ingredients have no proven ability to provide and benefit.

That means over 56% of this supplement has no benefit to increase natural testosterone levels – that’s shocking!

Considering this is marketed as the strongest testosterone booster, when nearly half of the total mass of the product doesn’t work it doesn’t leave much to brag about.

Especially when the excellent D3 is underdosed by quite a considerably amount compared to some of its competitors.

Plus it omits some other great in ingredients such as B6, K2, E, C, B12 or even Ginseng.

Unwanted Side Effects

There’s some issues though regarding the side effects of Sergeant Steel.

Tribulus is making a name for itself…

If you are on certain medication to control blood pressure please do not take this supplement.

Lab tests on animals link tribulus to problems in fetal development. So stay away from tribulus if you are pregnant or breastfeeding.

Women may also have period problems.

Also, men should be aware that there are some concerns about possible links between tribulus and prostate problems.

Both men and women may have problems sleeping with products containing tribulus.

Shilajit should not be consumed in a raw and unprocessed state because of metal ion contamination.
Calcium may line the arteries with plaque if supplemented for a long period of time.
Maca can act as estrogen.

Necessary Improvements?

This test booster from Assault Labs needs further development.

Sergeant Steel provides a few ingredients that should not be in this product such as Horny Goat Weed and Tongkat Ali.

Tribulus is not entirely safe and considering this is supposed to lower estrogen levels it includes Maca which may act like estrogen!

There are other ingredients that could have been included to improve its abilities.

Vit. C
B6
Oyster
Creatine
K2
Vitamin E
B12
Ginseng

Some of these proven ingredients are included in the best testosterone boosters such as TestoFuel.

Assault Labs Sergeant Steel Testosterone Booster Conclusion

This definitely hits the target on many levels.

It has a high dose of D-Aspartic Acid which is found in the best testosterone boosters.

It also contains D3, if not a bit low on the dose, Zinc, Magnesium and other proven ingredients.

But where it could excel and really power through to be the best testosterone booster on the market it fails because it includes so many other ingredients which are just not proven to be effective.

This has resulted in a colossal waste of over 2300mg, 2300mg that could have been made up of further proven ingredients to create an absolute tank of a testosterone booster.

Final Thoughts?

I am not suggesting this will not work and that it is not good, but when there’s a 9 of the 16 ingredients offering no particular benefit it seems to be a huge missed opportunity.

Take a look at what we have used for tried and tested natural results, here.
