October 26th 2021

Pack on muscle mass and cut bodyfat with your T levels turned up to the max.

The Golden Era bodybuilders knew that testosterone was the key to unlocking their incredible physiques. Ultimately, boosting their T levels was what enabled them to write their names into the history books.

In fact, they did everything they could to raise their T; including eating dozens of eggs and tons of butter, which were believed to be effective methods of boosting their hormones at the time.

But luckily for you, in the modern era, you have natural testosterone boosters at your disposal.

Check out the top 5 test boosters on the market:

1. TestoFuel by Roar Ambition

With so many products to choose from, making a decision on a testosterone booster isn’t easy.

Do you choose to trust the advertisements and guys trying to make money? It’s much better to rely on positive reviews and previous customer experiences, to ensure you receive a product that works.

Used by bodybuilding legend, Robby Robinson, TestoFuel provides you with a reliable, premium option when aiming to boost your testosterone levels.

We’ll give you a short review of TestoFuel below:


Increased Size & Strength 

The main benefit you’ll notice from taking TestoFuel, is being able to pack-on muscle mass and build your power much easier than before.

With the same amount of effort, you’ll gain size on your arms, chest, and legs, as well as working your way past your previous lifting records.

Enhanced Sex Drive

If you feel that your libido is low, you’ll feel 18 again once TestoFuel starts kicking-in.

After doing our research, we found that TestoFuel contains a safe and effective blend of nutrients proven to raise both your testosterone levels and sex drive.

Ultimately, revitalizing your sex life will strengthen your relationship and improve your mood too.

Faster Results & Recovery

It’s inevitable that you’ll find it harder to recover from intense gym sessions as you age – this is something you can’t escape.

But, by raising your testosterone levels, you’ll be less sore from each workout; allowing you to limit your time on the sidelines and make more progress towards your fitness goals.


The first small issue is that no retailer sells TestoFuel in their stores; you can only buy it from their official website – But if you prefer online shopping anyway, this won’t be an issue.

The second hurdle is its high price-tag. TestoFuel is more expensive than other test boosters on the market, but it’s also important to remember that it’s a premium product used by bodybuilding legends such as Robby Robinson too.

Key Features

TestoFuel contains the best mixture of test-boosting nutrients we’ve seen on the market.

In fact, you’ll be surprised by how rare it is for these supplements to contain an optimal dosage of Vitamin D3 (5,000IU) & D-Aspartic Acid (2,300mg).

Other clinically proven ingredients such as Asian Red Panax Ginseng, Fenugreek Seed Extract. As well as essential trace minerals, Zinc & Magnesium ensures that you’ll benefit from a raise in testosterone production.

And you won’t see another T-Booster containing premium Oyster Powder either.

2. Prime Male

This is a unique testosterone booster that’s aimed at men over 30; it’s niche, but it targets a real problem.

What’s the problem? Well, not many men know that their T levels drop after they reach the age of 30, by around 1% each year – that’s a worrying statistic, as testosterone is responsible for your vitality and sexual function.

As a result, if you’re in Prime Male’s target audience, it can be a great option for you.

Ultimately, this is another T-Booster containing 100% natural ingredients, that’s safe and proven to work.



Fights the battle to keep your T levels optimal – 4.5/5

Enjoy life at your peak throughout your 30’s, 40’s, 50’s or even 60’s. The mixture of tried-and-tested herbs in Prime Male will keep your testosterone stable and combat your naturally declining levels.

Gain muscle and trim body fat – 4/5

The increase in T levels will allow you to add inches onto your biceps, while taking them away on your stomach and waist.

Improved mood and libido – 4.5/5 

Find it easier to leave your bed in the morning smiling, as well as being able to fully satisfy your wife at night!


We’ve already mentioned that reliable products come at a cost. And this is no different with Prime Male – it costs more than TestoFuel, but remember that it’s targeted at a certain age group too.

Optimal dosage of D-Aspartic Acid 

D-Aspartic Acid is a key player when it comes to building your dream T-Boosting team. EvlTest contains a great dosage that’s shown to work in numerous studies.

Good dosage of Fenugreek Seed Extract

An ayurvedic herb that’s been used in traditional Indian medicine for a long time. Fenugreek Seed Extract is known for having a positive effect on your libido and T levels.


While EvlTest contains 2 key test boosting nutrients, it also comes with Tribulus Terrestris; this has recently shown to potentially cause prostate enlargement, which is something all men should try and avoid.

5. Anabolic Freak



Contains Vitamin D3

Anabolic Freak contains arguably the best nutrient at raising your testosterone levels, Vitamin D3.

Includes D-Aspartic Acid 

Another great ingredient when aiming to take your T to the next level, DAA is tried-and-tested to work.


While Anabolic Freak contains some great nutrients, it doesn’t contain optimal dosages of Vitamin D3 or DAA.

Why Do You Need Testosterone Boosters?

The reason why most people try testosterone boosters, is because they’ve reached a plateau that they just can’t break past. Or they just feel low on confidence and ‘mojo’ than usual.

Well, the most common cause of these issues is having low testosterone levels.

A raise in testosterone can deliver these benefits:

  • Increased Muscle Mass
  • Enhanced Strength & Endurance
  • Raised Libido & Energy Levels
  • Elevated Mood & Confidence

Ultimately, these are the main benefits that you should look for when choosing a testosterone booster. And if you choose the right product, you’ll receive a supplement that delivers not just 1, but all of them.

However, it’s important to know that many testosterone boosters contain potentially harmful or ineffective ingredients – that’ll simply waste your money without delivering any results.

As a result, it’s wise to do your research into the best and worst ingredients found in these supplements.

But to save you tons of time, we’ll show you the ingredients that you should avoid in testosterone boosters below…

Test Booster Ingredients To Avoid

This is arguably the most important section on this page. Knowing which ingredients to avoid will inevitably save you from suffering side effects and wasting your money.

So take a look at which ingredients we recommend that you stay away from:

Tribulus Terrestris

At the top of our list is Tribulus Terrestris. You might be surprised, because it’s actually a very common addition to natural testosterone boosters.

The bad news is that modern research has shown that Tribulus Terrestris has no effect on your testosterone levels – making it an ineffective ingredient in T-Booster supplements.

Not only that, the real reason why we recommend you to avoid this ingredient is this; Tribulus Terrestris has shown to increase risk of prostate enlargement.


The official name for this nutrient is Diindolymethane, and it’s a compound that’s naturally found in green vegetables such as broccoli and kale.

So why is it used in supplements? Well, DIM has shown to prevent your testosterone converting into estrogen when it’s raised significantly.

The important thing to remember is that natural T-Boosters aren’t going to have the same effect as steroids; it’ll take longer for these supplements to work than steroids, but they don’t put you at risk from increased estrogen levels either.

As a result, DIM simply isn’t needed in natural test boosters.

But the worst part is that DIM can actually increase estrogen synthesis when consumed in large dosages. It gets even worse, as ‘large dosages’ can be anything above 100mg per serving.

Ultimately, there’s no need for DIM in test booster supplements, so it’s better to avoid it, to avoid it’s potentially nasty side effect.

Proprietary Blends

Right, so you’ve probably guessed that this isn’t a single ingredient. But it’s one of the worst things in the supplements industry.

Why? Because companies use proprietary blends to hide ineffective dosages of nutrients, so you can’t see how safe or effective their product really is.

Simply put, these blends increases your risk from suffering side effects – especially when stimulants are added into them.

To ensure you get the best value for money product, we strongly recommend that you avoid testosterone boosters containing proprietary blends.

Best Testosterone Booster Ingredients

Now that you know the ingredients you should avoid, knowing what works is equally as important.

Now, it’s wise to check scientific studies to see which nutrients are both safe and effective. Once you know what to look for, you’ll give yourself a much better chance of finding a test booster that raises your T levels.

Fortunately for you, we’ve saved you tons of time by doing the research ourselves. Take a look:

Vitamin D3


There’s a reason why everyone is happy in sunny weather; the sun’s ray provides you with higher Vitamin D3 levels.

That’s right, your skin produces higher Vitamin D3 when your skin is exposed to sunlight. In fact, this is why it’s important for those in ‘less sunny’ countries to supplement with this ingredient.

In fact, studies have shown that while Vitamin D3 supports your general health and vitality, almost 50% of the population worldwide are deficient in this nutrient [1].

What’s more interesting is that Vitamin D3 is actually a hormone, as your body produces it naturally. So it’s no wonder that it’s proven to have a significant effect on your testosterone levels [2].

There’s been countless studies proving that Vitamin D3 is able to safely boost your T levels, and it’s something you can’t really argue against.

For these reasons, Vitamin D3 should be the first nutrient that you look for, when searching for an effective test booster supplement.

Optimal Dosage: 3,332OI-5,000IU per daily serving

D-Aspartic Acid


D-Aspartic Acid (DAA) has gained a reputation for being one of the most effective T-Boosting nutrients available.

It can be found naturally in food sources such as eggs, lean meats, fish and dairy. But to obtain optimal amounts to raise your T levels, consuming it through a supplement is your best option.

There’s been many studies proving that DAA is able to promote higher testosterone levels when supplemented between 2-3g per daily serving [3].

However, we will acknowledge that DAA can cause a reduction in testosterone when consumed in high dosages; studies have shown that this only happens when consumed in dosages around 6g (which is more than double the optimal amount).

So when choosing a test booster, make sure that it contains more than 2g, but less than 3g of DAA.

Ultimately, when consumed in the right amounts, DAA is undeniably another key ingredient you should look out for.

Optimal Dosage: 2,000mg-3,000mg per daily serving

Fenugreek Seed Extract


Our final recommendation of natural test boosting nutrients, is Fenugreek Seed Extract.

Interestingly, you can find this in curries; Fenugreek Seed Extract has been used in ayurvedic medicine for decades, and it’s more recently been proven to work in modern research [4].

Ultimately, this is safe, natural and effective.

Optimal Dosage: Above 50mg per daily serving

What Makes Testosterone Boosters Different To Steroids?

We’re answering this question, because those new to supplements are probably asking themselves this question.

Basically, testosterone booster supplements are natural products that are heavily regulated by the FDA. They raise your body’s natural production of testosterone, so you achieve higher levels.

On the other hand, anabolic steroids pump hormones directly into your body; this has a much quicker effect, but can cause severe side effects that you’ll want to avoid.

Ultimately, another big difference is that natural testosterone boosters are legal in the USA & UK, while anabolic steroids aren’t.

Bottom Line: Natural test boosters might take a few extra weeks to take effect, but they won’t put you at risk from gynecomastia (man boobs) or other severe side effects either.

Buy Direct From The Company

When looking to pack-on muscle mass, it can be tempting to look for the cheapest option in retail stores to save money. But the best products aren’t always found in stores.

Instead, specialist premium products are found online; companies prefer cutting out the middle-man to provide you with the best service directly. This allows them to ensure their customer support, reputation and brand loyalty remains high.

You’ll find that most premium companies offer money-back guarantees too, so you can try their products risk-free.

On the other hand, as retailers stock hundreds of supplements, they’re less likely to care about the user experience of each specific product.

Only Buy Products Manfactured In USA or UK

You might be thinking that this is similar to the whole ‘American cars are better’ debate. But it’s not.

Supplements manufactured in the USA & UK are put through strict cGMP & FDA guidelines before being sold to customers – to ensure you receive a high quality product every-time.

But these regulations aren’t always used in countries such as China. As a result, it’s important that you choose supplements manufactured in the USA & UK, so you receive a safe and effective supplement.


Key Tips For Gaining Muscle Mass

Since you’re looking for testosterone boosters, it’s likely that one of your key aims is to gain lean muscle mass.

Well, it’s important to remember that natural testosterone boosters aren’t just ‘magic pills’. They’ll speed up the process and help you gain lean mass, but you’ll have to put the effort into training and eating the right foods too.

To ensure that you do realize your fitness goals, we’ve provided you with some key tips below:

Calculate Your BMR

In case you’re wondering, BMR stands for ‘Basal Metabolic Rate’; this is the amount of calories you need to maintain your weight.

As a result, if you eat under your BMR, then you’ll lose weight. But most importantly, if you eat over your BMR, you’ll give your body the fuel it needs to build muscle mass.

Of course this is also dependant on other things such as protein intake too (we’ll expand on this below).

Keep Your Protein Intake High

When many people think of bodybuilding, the first supplement they’ll think of is protein powder. This is because everyone knows how important protein is, in order to build muscle mass, and even maintaining it during a cut.

But what many people don’t know, is how much protein you need to consume per day; this leads many people to become obsessed with their protein intake, drinking unnecessary amounts of protein shakes and wasting their money.

So how much protein do you need? Well, studies have shown that around 1.3g per kg of bodyweight is enough to support muscle growth [5].

For example, this means that an 80kg man would need 104g protein per day. Considering that 100g chicken breast offers 31g protein, that isn’t hard to reach naturally – and if you can achieve your dietary needs naturally without supplements, we recommend doing so.

One of the reasons we believe testosterone booster supplements to be useful, is because you won’t achieve an optimal amount of Vitamin D3 unless you’re constantly exposed to sunlight; this is impossible for those in ‘less sunny’ countries.

Try Different Rep Ranges

The ‘old school’ belief was that higher reps would leave you shredded, and that the 6-8 rep range was the sweet spot for muscle growth.

Since then, people have realized that their diet plays a more important role in muscle gains.

As a result, it’s best to try different rep ranges, and see which your body responds to best.

You might find that performing 10-12 reps leads you to making more gains than performing 6-8 did. The point is, you’ll never know unless you try new things – and this will also shake-up your old routine that your body is probably used to by now, giving you a better chance of making even more muscle gains.

Conclusion: Best Testosterone Boosters

We’ve provided you with all the information needed to make a wise, informed choice.

But the main thing to make sure you do, is not to simply rely on company advertisements; remember that they’re trying to sell you their products, and are usually prepared to say anything it takes.

Instead, a more reliable way of seeing which test boosters are safe and effective, is by analyzing its nutrient profile. The best T-Boosters will always provide you with the exact dosages of each ingredient inside them – so you can decide for yourself how good it really is.

TestoFuel has been rated as the best testosterone booster on the market. It has tons of positive reviews, and while it’s more expensive than others, it definitely seems worth the price.
