Best Testosterone Boosters That Shockingly Build Muscle Faster

best testosterone boosters man550

Testosterone is the most important hormone in your body for building muscle and getting stronger.

If you want to get jacked and make your training count, you should be doing everything you can to support your testosterone levels. The best testosterone boosters can be a good way to do it.

They’re formulated to:

  • Increase muscle size – Speed up growth & repair
  • Give you that extra boost – Naturally aids testosterone levels
  • Improves confidence & mood – Keeping you motivated to hit the gym

Some guys are genetically gifted, they will grow and grow, year on year. Other guys can drink tons of protein shakes, eat loads of steak and potatoes and switch up their workout and they still can’t grow.

A testosterone booster is designed for guys like this, hard gainers. It can be the secret to pushing past the barrier and releasing new muscle growth.

Okay, so what do they actually do?

The best ones use a combination of ingredients to safely support and encourage your body to produce more testosterone.

They do this by:

Aiding Testosterone Production – This relies heavily on processes in the brain and the endocrine system.

The needed components to accomplish this aren’t included in everyone’s diet. these products change that, filling in for those missing nutrients and ensuring the body is producing the most testosterone naturally possible.

Increasing Free Testosterone – About 60% of the T-Levels in a man’s body are bound to Sex Hormone Binding Globulin (SHBG).

When bound, this testosterone loses it’s anabolic potency and can no longer be directly used. T-Boosters decrease the production of globulin, freeing up testosterone availability.

Decreasing Estrogen – In the body, an enzyme known as the aromatase is responsible for the production of estrogen, even if it means converting testosterone to produce it.

Some T-Boosters contain ingredients that have the power to inhibit these enzymes, slowing the process down entirely. Decreasing estrogen while simultaneously increasing testosterone.

Only some products do this.

But, do test boosters actually work?

Some Bros seem to think the only real way to raise your testosterone level is with steroids or pro-hormones.

This is the highest form of bullshit. Getting real for a second, testosterone boosters are not as powerful as the synthetic stuff, but that doesn’t mean they’re ineffective.

Research over the last few years has discovered a number of natural ingredients that have been clinically proven to raise and support testosterone levels. Without the dangerous side-effects of steroids or pro hormones.

BroScience’s Best Testosterone Booster Ingredients

Not all testosterone boosters are effective. Many of the products on the market were formulated years ago and contain old, ineffective ingredients.

We’ve dug deep and found the most effective ingredients available right now, all with real clinical studies behind them:

daaD-Aspartic Acid – An essential amino acid to the testosterone boosting process – through a reaction with the brain, D-AA helps the body release a multitude of hormones. These include the luteinizing hormone (regulator of the testes), follicle stimulating hormones and perhaps most importantly, growth hormone – a key muscle builder.

There has also been studies that believe D-Aspartic Acid to be an effective component for removing rate-limits of testosterone synthesis.


oysterOyster Extract – Potentially one of the most effective testosterone increasing ingredients out there. Oysters hold a lot of zinc, up to 10x more than the amount you’ll find in a steak. Zinc, like D-Aspartic Acid is great for releasing those luteinizing hormones and help out with raising serum testosterone levels.

That’s not all, Oyster Extract also holds 59 elements of essential bodily nutrients such as vitamins, amino acids, omega 3 & 6 and taurine. It has also been seen to raise IQ, help out with strength gains and raise the immune system.


nettleStinging Nettle 
– Working closely with Sex Hormone Binding Globulin, the nettle’s ‘lignans’ which make up part of the root binds with the SHBG in place of the testosterone. This allows more testosterone to be free in the body. It has also been seen to have aromatese inhibitor qualities to lower the estrogen production rate.



vitamin-d3-supplement-8Vitamin D3 – Called a vitamin, but actually a hormone. D3 is 1 of the only 24 nutrients we need to stay alive. Vitamin D3 is absorbed from the sun, but usually, we don’t get enough of it.

As modern living keeps us constantly indoors – our supply to this hormone is limited.

D3 helps release luteinizing hormones which help release testosterone, follicle stimulating hormones and growth hormone.


Ginseng – This extract has been rocking the testosterone world. Ginseng has the ability to boost Nictric Oxide levels in men. In doing so it allows blood flow to massively improve giving fantastic pumps during a workout.

It also decreases the body’s glucose levels, eliminating any worries about insulin interfering with the testosterone production process. The saponins in Gingseng also improve testosterone levels and the luteinzing hormone.

It’s the Asian Red Panax Ginseng form that is the most effective.


Ingredient Warning

Stay away from a product with a proprietary blend in them. This is a group of ingredients all mixed together in various amounts. It’s bad because you don’t know how much you’re getting of each ingredient.

We also recommend staying away from products that were not formulated in the last couple of years. They were not formulated using the latest research.

Are there any side effects?

These products are not steroids. They are completely natural supplements designed to deliver your body the nutrients it needs to produce the most testosterone. They don’t cause any side effects. They will not give you ‘man-boobs’, shrivelled balls or cause ‘roid-rage’.

Broscience’s Top 3 Best Testosterone Boosters

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

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


testofuel broscience best tesosterone boosters

When researching T-Boosters this one came up a lot. So many online reviewers cannot get enough of TestoFuel – so we had to check out why.

The Good

TestoFuel is an extensively researched anabolic support complex that was apparently formulated to achieve the following things:

  • Muscle Growth – Helps further develop your physique
  • Improved Strength – Expands your lifting limit
  • Reduced Body fat – Aids in managing a bulk
  • Raised mental state – More alert and motivated

It does this by using some of our favourite ingredients mentioned above. Using large amounts of  D-Aspartic Acid, Vitamin D3 and Oyster Extract.

There’s no proprietary blends here. And all of these ingredients are natural with no nasty side effects. It won’t show up on a drug test.

We found this customer video on youtube:

The Drawback

Premium priced. But you do get 120 large capsules per month, that’s 4 capsules a day.

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 best product on the market right now for naturally raising test levels and building muscle.

The only real downside we could find is the price. $65 for a month supply, but if you buy 3 you get 1 for free, plus other free goodies. So, that works out at about $48 per month.

2. Prime Malebest testosterone boosters prime-male22


This is another T-Booster we came across that was also highly praised. Prime Male is a booster aimed at older guys as testosterone levels naturally start to decline.

The Good

Prime Male’s designed to reverse ageing T-levels and boost them back to their optimum levels, which sets it apart from most of its competition.

The benefits of Prime Male include:

  • Higher Energy Levels – Train for longer
  • Gain Muscle Mass – More growth from increased testosterone
  • Shedding excess weight – Lose unwanted pounds
  • Better mood & Higher Libido – Improved cognitive function and sex drive

And it uses proven ingredients like Luteolin, Stinging Nettle, Vitamin D3 and D-Aspartic Acid.

Luteolin deserves an honourable mention. After being compared against over 1400 other natural compounds, Luteolin was seen to be the strongest for decreasing estrogen production by being proven the best aromatase inhibitor. Read the study below.


It uses no proprietary blends.

The Drawback

Prime Male doesn’t contain as much D-Aspartic Acid as TestoFuel – however the main battle at this age is SHBG, which this product handles well.

You can only buy it from their website, but they do have a 90-day return policy.

More expensive than most T-Boosters, running you about $69 a bottle, however, we believe the quality is strong enough for the company to stand behind it.

BroScience Verdict

From the research we’ve done on these products, Prime Male is the best choice for older guys with a low energy levels and libido. It uses all the right ingredients and strong aromatase inhibitors.

It is however, another premium priced product. But as the old saying goes: you get what you pay for.

You can find out more at their site:


zma jym


The ZMA formula – Zinc, Magnesium and Vitamin B6, 3 important nutrients for supporting testosterone levels.

This one is ZMA JYM from the well known Jim Stoppani.

The Good

JYM Supplements looks to reduce the amount of proprietary blends on the market, which is a good sign.

ZMA JYM aims to:

  • Restore Optimal Hormone Levels – Balance Testosterone Levels
  • Muscle Strength – Helps muscle growth processes

Using Zinc & Magnesium, ZMA JYM balances deficiencies of the two elements in athletes – JYM Supplements believe this is the key to supporting test levels.

The Drawback

More of a testosterone supporter than an actual booster.

Can only be bought from

BroScience Verdict

If you’re just looking to support your testosterone levels and you are on a budget then this could be a good product for you. It’s only around $15 – 20 per bottle.

It contains some essential ingredients for testosterone levels but it is lacking the business ingredients like D-Aspartic Acid and Vitamin D.

Overall Conclusion

TestoFuel is the product that overlapped most with our research and findings in a positive light. There are reviews and testimonials all over the web and on social media. It is the number 1 product on the market.

On the other hand if you’re middle aged or above and experiencing the negatives of getting older. We recommend using Prime Male – it contains more aromatase inhibitors to combat estrogen, which becomes an issue once you reach middle age.
