My Neanderthal Primeval Labs Testosterone Booster Review

My Neanderthal Primeval Labs Testosterone Booster Review First Look:

I had a long weekend away with the better half in London, there was lots of walking plus plenty of drinking and eating.

So much so, that every afternoon we had to return to the hotel for a disco nap.

I have never felt so tired after wandering around, it nearly finished me off and the curse of age was certainly making itself more evident.

There was a gym and spa on site but neither managed to get any use.

Since we returned I slept for pretty much a whole day and then following night before hitting work again on Monday.

With more vacations looming on the horizon with a couple of long distance ones I am more eager than ever to ensure my energy levels of as high as some of the buildings were we walking around.

I also found getting back on to the bicycle to ride to work and back a bit of a shock to the system with my legs aching quite considerably.

Upon returning to the gym, I found the shoulder press a real struggle.

I also had run out of my favorite testosterone booster which had ensured that as I cruised past the age of 30 and leaning towards a solid mid-thirties position I felt strong and energetic.

At present, I do not feel either of those two things.

Knowing that a key ingredient of an effective testosterone booster is vitamin D3, I noticed this D3 and Calcium supplement on Amazon.

I had previously tried a weight control supplement from Swisse Wellness and while it contained three good ingredients, it offered nothing else and it all felt a bit lacking.

Let’s see how this performs.

Ingredients: The Science

Rhodiola rosea – Can protect against cognitive deficits, neuronal injury and oxidative stress, can also be used as a potential agent in treatment of neurodegenerative diseases.

DIM (Diindolylmethane) – Diindolylmethane appears to promote a healthy balance of testosterone in the body and is found in vegetables such as broccoli.

Cruciferous vegetables which contain high levels of DIM such as broccoli are eaten by many professional athletes such as rugby league players for their benefits.

Ashwagandha (Withania Somnifera) – Studies have shown that treatment with Ashwagandha root extract resulted in a higher level of testosterone and a concomitant increase in serum levels of LH among infertile men having sub-optimal testosterone levels.

It’s difficult to see if the same result would be found with guys who do not have any fertility issues. So the question is, are you infertile?

If you’ve been banging your missus (or even your mistress, we shouldn’t be even talking if you have smashed your sister) unprotected and have miraculously not had a sprog you probably are infertile…sorry to break that to you, bro.

However, you are probably in look because only 12% of men throughout the whole world are infertile, and even then, that is a generous estimate by the World Health Authority.

Carnitine – Acetyl-L-carnitine helps the body produce energy. It is important for heart and brain function, muscle movement, and many other body processes.

Men who were supplemented 2g per day showed an increase of Insulin like growth hormone when combined with exercise.

Very limited evidence to suggest any fat loss unless you are an elderly person.

Maca Root – This Peruvian strain of ginseng is great for lifting libido and mood, however, when it comes to raising testosterone levels it has no effect at all.

No significant influences on testosterone in any tested demographic I’m afraid.

D-AA, D-Aspartic Acid – D-aspartic acid is one of two forms of the amino acid aspartic acid. The other form is L-aspartate.

The benefits of D-AA are specific to it, and do not extend to aspartic acid or L-aspartate.

  • D-AA can be used as a testosterone booster for infertile men, and by athletes as a booster.
  • D-AA works in the central brain region to cause a release of hormones, such as luteinizing hormone, follicle-stimulating hormone, and growth hormone.
  • It may also build up in the testicles, where it alleviates a rate-limiting step of Testosterone synthesis, which leads to a testosterone increase.

Zinc – Needed for many reactions in the brain and a key component for releasing the luteinzing hormone (LH).

LH is primarily responsible for theproduction of testosterone and growth hormone. The fact that it’s in here is great.

Vitamin B6 – Vitamin B6 helps testosterone levels by stimulating androgen (a steroid hormone that acts as a precursor for testosterone) receptors in your body, making your testes produce testosterone.

Vitamin D – This is a great Testosterone boosting vitamin that must be taken advantage of to trigger further production of Testosterone in your body.

However, there are two types of Vitamin D. There’s calciferol (vitamin D2) and cholecalciferol (vitamin D3) – we are only interested in cholecalciferol which is D3; this is the type our skin synthesizes from the sun and becomes a hormone which results in the increases in our testosterone.

Research by the US Library of Medicine has shown that testosterone productions are increased with Vitamin D3 supplementation.

It is also good to heal scar tissue according to recent studies from the University of Birmingham, UK.

There’s a plenty of articles I have written covering the benefits of D3 you can read about, here, here and here.

Boron – Boron is great for the older lifter or those doing high weight low rep work as it helps to reduce inflammation, something that is found in PrimeMale, which I am a fan of.

Also helps raise testosterone levels.

L-Dopa (Macuna Pruriens) – This is actually good for treating people with Parkinsons. There’s a mixed bag of results for testosterone but look mainly positive.

Results have shown an increase in testosterone levels in infertile men, however, results are very limited for fertile men.

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


1 scoop per day mixed with water.

We would recommend that you have at least 4 tablets or doses spread evenly across the day, as per the best testosterone booster on the market.

This way your body has a constant trickle of the ingredients to work with in order to stimulate testosterone.


There are a good number of proven and effective testosterone stimulating ingredients present here:

  • Boron
  • D3
  • D-Aspartic Acid
  • B6
  • Zinc

D3 is a great testosterone boosting ingredient and many of us are deficient in D3.

It is also more effective than D2.

However, it is not just testosterone levels which benefit from D3 either; bone and teeth health plus it is needed by stem cells for muscle regeneration and recovery after a hard session and there is evidence it might protect immune functions during periods of intensive training.

D3 is more of a steroid hormone than a vitamin in the way it acts on the body.

D-Aspartic Acid is proven to increase testosterone levels as are Zinc, B6 and Boron also reduces inflammation.

This is key, because too much inflammation has a negative impact on testosterone levels.

It is also good to see that DIM is included.

While DIM is not actually a testosterone boosting ingredient, it does regulate the female hormone estrogen. Too much estrogen inhibits testosterone production.

Ashwaganda can help increase testosterone levels, but you have to be infertile for it to be effective.

This is much the same for Macuna Pruriens with is effective if you are an infertile male but does also reduce stress.

Rhodiola is great for brain function, it is more commonly found in nootropics supplements that help improve brain health.

Carnitine is also worth a strong mention because it is effective to improve bodily function but also, when dosed at 2000mg per day, is able to increase growth hormone when you exercise too.


It is a good sign when there’s only one ingredient present that is not proven to offer any testosterone boosting benefit, or benefit towards testosterone levels.

However, that does not make this the best; there’s a few factors that let this down slightly.

The problems I see here are this:

Ashwagandha and Macuna Pruriens are only effective at increasing testosterone levels if you are an infertile male.

So, if you fall within the 12% of men throughout the globe who are infertile (this is according to the World Health Organization) this will benefit you.

If you are not infertile, and the majority of men are not, these two ingredients offer no benefit for stimulating testosterone levels.

Another thing is this, and I know it is being a little bit picky but it needs to be addressed.

While powders seem to be popular at the moment for supplements, they are not that convenient, not as convenient as pills anyway.

The tub is bigger and you have to use a mixer and carry that around as well as measure out the supplement.

With pills you just pop one and swig it back with a drink. Nice and simple.

Plus, with the best testosterone booster, you space your daily dose over the day.

This means that there’s less excess ingredients that risk being wasted if the body doesn’t require them at the time.

My Neanderthal Primeval Labs Testosterone Booster Review Conclusion:

On the whole this is a great supplement.

There’s a good number of proven testosterone stimulating ingredients included in good doses.

However, there are a couple of ingredients which are beneficial but do not actually stimulate testosterone production.

These could have been replaced with other, proven and beneficial ingredients that can actually increase production of testosterone.

There’s also two ingredients that are only helpful if the user is infertile, but that limits the majority of the population.

As a result it is not quite as effective as stimulating the most testosterone because it is lacking other, further proven ingredients such as:

  • Magnesium
  • K2
  • Fenugreek
  • Oyster
  • Ginseng

Due to the limitations, plus the additional missing ingredients that would offer a better, well rounded product this is not quite the best on the market.

You can see what the best testosterone boosters are, here.
