Best Testosterone Boosters in 2020 - Top 9 Supplements

Best Testosterone Boosters in 2020 – Top 9 Supplements

Finding the best testosterone boosters among the plethora of supplements on the market is hard, right?

I know you’re nodding in agreement.

The truth is, there are some seriously potent natural ingredients that science shows take T-levels to the max. However, you have to separate the real players from the snake oil.

Guys using the clinically proven T-heighteners as a part of their nutrition have witnessed their hormone levels increase stratospheric. Thus enabling them to build significant muscle, take their fitness to the next level, drop fat, and become machines in the bedroom.

Testosterone levels decline with age and some men want to get back the t-levels they produced when they were in their prime.

Because the hormone testosterone is associated with a lot of essential functions in the male body, these include increased sex drive, stamina, greater muscle mass, increased energy levels, and more stamina.

Stick with me as I reveal the top nine testosterone boosters and later on the best testosterone booster supplements.

Best Testosterone Booster Supplements

best testosterone boosters that work
TestoFIERCE is head and shoulders above the rest.

After countless hours of research, comparison, and endlessly looking into studies – it’s finally done.

We made a list of the top supplements to increase testosterone levels.

These are the top products that we found on the market right now, and they have all been formulated using the latest research and natural ingredients.

1. TestoFierce

best testosterone booster that works

After examining the ingredients label, I instantly realized why it’s considered the most potent natural testosterone booster on the market.

The Good

TruFierce used a science-based approach to manufacture the most potent testosterone supplement available in 2020: TestoFierce

There are no proprietary blends, so you know exactly what ingredients and doses you’re getting. They have nothing to hide, simply because it’s a fantastic product.

It has been formulated to:

  • Improve natural testosterone production
  • Speed up muscle growth – Get jacked in months instead of years
  • Reduce body-fat – Get ripped and hard muscles instead of puffy and soft
  • Supercharged strength – Improve personal records in the gym faster
  • Increase stamina – Expand your limits in and out of the gym

They achieve with this a properly dosed formula that was formulated on evidence from scientific research. TestoFierce contains 11 powerful test boosting ingredients.

These include:

  • Boron
  • D-Aspartic Acid (DAA)
  • Ashwagandha
  • Zinc
  • Vitamin D3
  • Magnesium
  • Fenugreek
  • Vitamin B6
  • BioPerine
  • Vitamin K
  • Asian Ginseng

Exactly crucial ingredients you want to see in a natural testosterone booster.

They’re currently offering great package deals.

Another thing I’d like to say is this:

The great thing about Testofierce (and Trufierce as a company in general) is that they aren’t making any ridiculous claims, even though they have superior products. Which is nice to see in this corrupt industry.

The Drawback

Premium-priced product. There’s no pixie dust or fillers in this test booster. Every single ingredient is max dosed, has studies behind it, and therefore you need to pay a premium. At least you know you’re getting the best of the best, which is all that matters, right?

Seven pills per serving. It sounds like a lot, but it is logical when you think about it. How else would you be able to get all the best ingredients in the proper amount? Makes you question all the other 2-5 capsules serving products out there.

You can only buy direct from their official website. They do offer fast shipping so it shouldn’t matter too much.

BroScience Verdict

Overall, TestoFierce is the number one testosterone supplement this year. Their evidence-based approach sets them apart from the rest. Every single ingredient we looked at is adequately dosed, and they don’t leave anything out that works.

It was designed to boost your testosterone productions, which in return will help you build muscle, increase stamina, lose fat, and get stronger more quickly.

The only downside is the price $65 for a 30 day supply. But since it’s a 210 capsule product, you’re getting fantastic value for your money. And if you go for any of their package deals, it works out at a steal deal ($39 / bottle), to be honest.

2. TestoGentestogen best testosterone booster

When doing my research, this one came up a lot. So many men can’t get enough of this product, so I had to take a closer look.

The Good

TestoGen has been one of the best testosterone boosters for years now. and recently, they updated their formula improving the ingredients.

Testogen formula

There are no proprietary blends, so you know exactly what you’re getting, and it is formulated with this in mind:

  • Improve natural testosterone production
  • Fast Muscle Gains
  • Reduce Body Fat 
  • Superior Strength
  • Increase energy levels 

They’re able to achieve that with their new updated superior 11 fundamental natural ingredients formula that includes almost all of our favorite test boosting ingredients, plus some more.


  • Boron
  • Vitamin D3
  • D-Aspartic Acid
  • Nettle Leaf Extract (stinging nettle)
  • Ginseng
  • Fenugreek
  • Bioperine

On top of that, they also include Vitamin K1, Magnesium, Vitamin B6, and Zinc in their formula.

They have fantastic package deals:

  • Buy 2 Get 1 FREE
  • Buy 3 Get 2 FREE

Plus, shipping is always free with every order while supplies last.

We found hundreds of happy customer reviews, and here’s an example:

testogen reveiw

This guy put on muscle and lost a lot of body fat in just one month with his improved testosterone production and is on his way to more gains.

best test booster review

Nolan reported having increased strength significantly while gaining 7 lbs of lean muscle.

If you want to see more, their product visit their website here.

The Drawback

Premium-priced product. It’s no secret that the top testosterone boosters are premium priced due to their effectiveness. TestoGen is no exception. You do, however, know that you’re getting one of the top test booster available on the market.

You can only buy from their official website. It means you can’t walk into GNC or shop for it on Amazon. However, they do ship worldwide to every country in the world for FREE.

BroScience Verdict

Overall, TestoGen is one of the best testosterone boosters for sale this year. It was formulated to increase natural testosterone production so that you can build more muscle, lose fat, and get stronger.

It lacks in some areas if you compare it to TestoFierce.

Another downside was the price. $59.99, which is almost the same as TestoFierce, but TestoFierce is a lot better.

3. TestoFuel

testofuel t-booster

TestoFuel has been around for a few years now and has excellent customer reviews.

The Good

TestoFuel uses no proprietary blends and only vital natural ingredients that help you:

  • Increase Muscle Growth – Helps further grow lean muscle mass
  • Improve Strength – Expands your lifting limit
  • Reduced Body fat – Aids in managing a bulk
  • Raised mental state – More alert and motivated
  • Increased Sex drive

It does this by using some of our favorite ingredients mentioned above.

TestoFuel has a solid customer base and has been around for years.

The Drawback

Premium-priced and you have to pay extra for shipping.

You can only buy TestoFuel from their website; however, there is a money-back guarantee. They also ship internationally from the USA and UK.

BroScience Verdict

Considering the number of proven ingredients and their amounts, Testofuel is the 3rd best product to boost testosterone levels.

Even though it’s decent, you cannot overlook that the doses, ingredients, and overall quality is severely lacking compared to TestoFierce.

The Ultimate Scientifically Proven Testosterone Boosters

Whether looking for a sole-ingredient testosterone booster, or one which combines numerous compounds, these are vital ingredients you need to be knocking back.

1. Boron

Let me start this top testosterone boosters list with a relative newcomer to the T-rocketing arsenal.

For years, science has known boron strengthened the cell walls of plants. But, it wasn’t found to elevate T-levels until 2011.1

Research, published in the Journal of Trace Elements in Medicine and Biology, demonstrated that ingesting just 10 mg of boron per day, over a seven-day period, had dramatic effects on testosterone.

The scientists discovered that this element had the effect of:

  • Lowering SHBG (sex hormone-binding globulin)—preventing it from “imprisoning” testosterone, which would otherwise render it ineffective.2
  • Increasing levels of free testosterone.
  • Decreasing production of the female hormone estradiol.
  • Elevating vitamin D levels—another potent T-booster.

Benefits of Boron

In addition to taking testosterone off the scale, research shows that boron can also:

  • Raise bone strength.3
  • Boost absorption of magnesium—another T-heightener.
  • Protect against oxidative stress.
  • Fight against diabetes.4

Boron Dosage and Side Effects

Currently, there’s no RDA (recommended dietary allowance) for boron.5

Ideally, for testosterone-boosting advantages, look to take around 10 mg per day (as in the study above). Current recommendations indicate that daily intake shouldn’t exceed 20 mg.6

Side effects are rare, but some users have reported tremors, dizziness, weakness, and headaches when consumed to excess.

2. D-Aspartic Acid

You probably already know the immense power of amino acids to build muscle. However, it may come as a surprise that they can also be one of the top testosterone boosters.7

Perhaps the most potent of these compounds for taking your natural steroid production through the roof is d-aspartic acid.

In 2000, experts published some shocking evidence in the FASEB Journal (Federation of American Societies for Experimental Biology). It demonstrated that d-aspartic acid elevated the production of LH (luteinizing hormone)—the compound which signals the testes to produce testosterone.8 9

It doesn’t end there.

Another study, first released in the respected publication Advances in Sexual Medicine, reported that a daily dose of just 2.6 mg of d-aspartic acid per day raised T-levels by 30-60 percent.10

Benefits, Dosage, and Side Effects

In addition to boosting LH and testosterone, D-aspartic acid also heightens fertility by increasing sperm production.

The majority of studies that show a positive correlation between d-aspartic acid intake and testosterone elevation utilize a dose between 2.6-3 mg.

Few users experience side effects when using this amino acid, although there are some reports of:

  • Irritability11
  • Nervousness
  • Rapid heartbeat.
  • Headaches

3. Vitamin D3

Evidence published in the journal Hormone and Metabolic Research revealed that supplementing with 83 mcg of vitamin D3 elevates both bioactive and free testosterone.

Participants exhibited increases on average by 53 nmol/l—whereas those taking a placebo showed no change.12

Additionally, it’s also recognized by scientists that you require adequate levels of vitamin D3 to enjoy healthy erections.13

Benefits, Dosage, and Side Effects

Apart from sexual health, vitamin D3 is essential for healthy bones, a robust immune system, and insulin management. 14 15 16

The RDA of vitamin D3 is 15 mcg per day for regular health advantages. The above study utilized 83 mcg to boost testosterone, although it’s generally agreed 50 mcg will promote T-formation.17

Additionally, you can use this example of one of the most solid testosterone boosters with confidence. Side effects are rare and usually, only occur through severe over-supplementation (around 400 mcg per day). These can include heart issues and kidney stones.

4. Ashwagandha

Also known as Withania Somnifera and Indian ginseng, people have been using ashwagandha for centuries in Ayurvedic medicine.18

Primarily, people have taken this herb to relieve both stress and anxiety. Yet, we now know that it’s also one of the top testosterone boosters.19

In 2009, evidence published by the CSM Medical University (Lucknow, India) demonstrated that consuming 300 mg of ashwagandha resulted in testosterone increasing by 96.2 ng/dl. The supplement was taken over an eight-week period.20

Benefits, Dosage, and Side Effects

The above study also revealed some additional benefits for the bodybuilder. Participants in the research not only saw their T-levels elevate but additionally:

  • Muscle mass heightened.
  • Strength increased.
  • Body fat percentage dropped.

For testosterone elevation, look to consume between 250-500 mg per day. Adverse effects are minimal, although some users have experienced nasal congestion, constipation, and drowsiness.

5. Magnesium

An immense element, and one of the most effective testosterone boosters for the bodybuilder.

In 2011, research from the University of Selcuk revealed some dramatic findings. Participants consumed 10 mg per kilo of body weight daily (over four weeks). Some were encouraged to exercise, the others to remain sedentary.

Those who took part in no physical activity witnessed an increase in testosterone. However, those who took magnesium and exercised saw a greater elevation.21

Hence, if you’re lifting weights and using this element, your T-levels will skyrocket.

Benefits, Dosage, and Side Effects

This compound is essential for the weightlifter. Experts explain that this mineral can:

  • Improve exercise performance.22
  • Improve focus and mental health.23
  • Reduce blood pressure.24
  • Lower inflammation.25

The RDA for magnesium is 400 mg for men—although most people agree that 200 mg is sufficient to stimulate testosterone production.26

Side effects usually only occur in overdose situations, as the kidneys eliminate excess magnesium through urine. However, if intake exceeds 5000 mg per day, it becomes toxic.

6. Fenugreek

While a popular ingredient in Indian curry dishes, fenugreek is also one of the most excellent testosterone boosters. This is because it has a two-pronged action.

Evidence published in the Journal of Sport and Health Science revealed that fenugreek blocks testosterone from turning into estrogen.27

Naturally, if the male hormone converts to the female, this reduces your T-count—inhibiting its muscle-building and sex-fuelling power. Additionally, excessive estrogen can lead to unwanted side effects of water retention and gynecomastia.28

This same study illustrated that fenugreek could “free” testosterone that is imprisoned by SHBG. While bound, it cannot be used to build muscle.

Benefits, Dosage, and Side Effects

If its T-boosting power isn’t enough, this compound can also improve blood sugar levels and lower cholesterol.29

Take 300 mg of fenugreek per day (as in the above study) to boost testosterone.

While studies on animals have shown some side effects, in human research, the only adverse reaction appears to be lack of appetite. Anecdotally, some users report a sweet body odor.30 31

7. Ginseng

For centuries, guys have been taking ginseng as an aphrodisiac in traditional medicine. However, it appears that this reputed use as a basis in science.

Back in 1996, scientists discovered that this powerful root not only raised testosterone levels, but also heightened the production of LH. This increase in T-count could be responsible for the rise in libido that ginseng is reputed to promote.32 33

Benefits, Dosage, and Side Effects

This plant extract isn’t just one of the top testosterone boosters; it can also take your sex drive to the next level.

In addition to its sex-drive boosting properties, ginseng also promotes mighty erections.

It stimulates the production of nitric oxide—opening the vessels of the penis with boner-forming blood.34 35

For serious T-boosting effects, consume between 100-200 mg of ginseng daily.

Users report a few side effects with ginseng, although in a small number of people it may cause:

  • Diarrhea 36
  • Headaches
  • Insomnia

8. Zinc

Zinc remains one of the most potent natural ingredients on the list.

Papers published in the Asian Journal of Andrology indicate that supplementing with 40 mg of zinc per day elevates testosterone levels.

Furthermore, this same effect has been demonstrated in numerous other studies—such as those published by the American Journal of Hematology and from the Wayne State University School of Medicine.37 38 39

You often times see zinc magnesium and vitamin b-6 together often times referred to as ZMA.

Benefits, Dosage, and Side Effects

Not only will zinc get your testes working in overdrive, but it will also:

  • Elevate strength.40
  • Raise endurance.
  • Boost the immune system.41

To raise T-levels, consume 30-40 mg of zinc per day. However, this is one ingredient you really shouldn’t overdose on.42

Ensure your zinc intake doesn’t exceed 60 mg per day. Excessive consumption of zinc can lead to:

  • Vomiting.
  • Loss of appetite.
  • Abdominal cramps.
  • Diarrhea.


DHEA is a steroid hormone we naturally produce it can convert into testosterone and estrogen.

DHEA levels in the body naturally decrease with age, which is why people use it as a supplement.

Benefits, Dosage, and Side Effects

  • May increase sex drive
  • Helps burn fat
  • Can elevate testosterone levels

DHEA dosages can vary, one study used a dose of 50 mg per day which was effective for elevating testosterone levels.

DHEA can be harmful when used in a large dose by mouth for a long time and may come with several side effects, including high cholesterol, cancer, liver problems, enlarged prostate, and more.

    Great article with a lot of useful information. I completely agree with your top three picks. I have done a ton of research as well. Currently I am taking Testogen for over two months and it has worked for me. It has double my low T and I am 61 years old. I do feel better and have more energy. Even have morning wood sometimes and haven’t for a long time.
    I tried Nugenix a long time ago and sorry to say, it did nothing for me.
    Thanks again for all the great information.
