With so many looking towards better lifestyles, more people are enjoying supplements and boosters to help them lead a fitter and healthier life.

While there are many different kinds of supplements and boosters, testosterone boosters are quickly becoming one of the most popular.

In this article, we’ll take a look at what testosterone boosters are, why people are looking to increase testosterone production, how it benefits health and fitness, and which are the best UK testosterone boosters on the market.

What is testosterone?

Testosterone is a naturally occurring hormone produced in the body in both men and women. Although women produce only a minimal amount of testosterone, the hormone affects a number of bodily functions, including bone density, muscle mass, sex drive, and hair growth and distribution.

Normal testosterone levels vary by age but a normal testosterone range in males aged between 19 and 39 sits at 264 to 916 ng/dL of blood. For women, it is much lower, at 15 to 70 ng/dL of blood.

There are several reasons why a person might want higher levels of testosterone, including to treat hypogonadism, to increase their sex drive, and energy levels, to improve their improve mood, and to help muscle growth.

Exercise and diet both play a big role in healthy testosterone production and several foods are known to promote healthy testosterone levels, including fatty fish, dark, leafy greens, cocoa products, eggs, avocados, and shellfish.

Now more than ever, however, people are starting to turn to testosterone boosters and supplements to help boost testosterone levels and give them the edge that they need in their daily activities.

What are testosterone boosters?

By definition, testosterone supplements and boosters are artificially produced substances to help raise testosterone levels within the body. A number of different types exist, including:

  • Injectable testosterone

  • Transdermal testosterone

  • Oral testosterone capsules

  • Testosterone boosting supplements

While most of the above are used for medicinal purposes, as mentioned, testosterone boosters, such as capsules and supplements, can be enjoyed as part of healthy exercise regimes and diets.

With that in mind, let’s take a look at some of the best and highest-quality testosterone boosters found available online in the UK.

The Best Testosterone Boosters UK

Prime Male - Best Overall

Elm and Rye - Most Popular

Hunter Test - Highest Dose

Testofuel - Best For Muscle Mass

Testo-Max - Runner Up

Prime Male

Likely the best-known testosterone booster on this list, and for good reason. Although many testosterone boosters are aimed at bodybuilders and fitness lovers, Prime Male is for the average man looking to give their testosterone levels a boost in a safe and effective way.

Designed and manufactured by Roar Ambition, one of the UK’s most prominent and respected supplement brands, let’s take a look at Prime Male and see why so many are turning to it to help balance their hormone levels.

What are the benefits of Prime Male?

According to the label, the testosterone booster provides a number of high-quality ingredients that offer a range of benefits, including:

  • Better hormone balance

  • More energy

  • Denser muscle mass when working out

  • Stronger libido

  • Less brain fog

To make the most out of Prime Male, like any testosterone booster or supplement, the capsules should be enjoyed in combination with a healthy diet and lifestyle.

Some users also enjoy Prime Male alongside other supplements such as multivitamins or greens powders.

What’s in Prime Male?

With an all-natural list of ingredients, Prime Male offers an even and intelligent spread, including a few fan favourites, such as D-Aspartic Acid, Zinc, and vitamins D3, K2, and B6. According to the label, each supplement contains:

  • Vitamin D3 – 5000 IU

  • Vitamin K2 (as Menaquinone 7) – 45 mcg

  • Vitamin B6 (as pyridoxal 5 phosphate) – 7.5 mg

  • Magnesium (as Magnesium Citrate) – 100 mg

  • Zinc (as Zinc Citrate) – 30 mg

  • D-Aspartic Acid Calcium Chelate – 1600 mg

  • Asian Red Ginseng 4:1 Extract (root) – 120 mg

  • Luteolin – 60 mg

  • Mucuna Pruriens (seed) Ext. (standardized to 15% levodopa) – 300 mg

  • Nettle Root 10:1 extract – 160 mg

  • Bioperine – 10 mg

  • Boron (as boron amino acid chelate) – 5 mg

The most essential ingredient in the above is arguably Vitamin D3, which has been featured in several studies researching ways to improve testosterone levels, with the UK NHS recommending that everybody take a supplement especially due to the fact that most modern work environments result in UK men being deficient.

As so many people have deficiencies of the vitamin, Prime Male offers a great way to boost levels of such a much-needed vitamin that helps boost the immune system and control bone density.

Another big hitter includes the likes of Magnesium, which helps free testosterone levels (the amount you have available in your blood at any one time) by inhibiting Sex Hormone Binding Globulin (SHBG), which reduces testosterone’s overall anabolic potency.

Additionally, both Zinc and D-Aspartic acid are regular features within all quality testosterone boosters and both help promote healthy levels of testosterone.

Both of these work to improve levels of the Luteinizing Hormone (LH), a precursor to testosterone that helps promote growth hormone production.

It’s worth noting that Boron and Luteolin are both welcome additions to the ingredients, as they help regulate levels of estrogen, which is important for overall health in older men.

When should you take Prime Male?

For the best results, it is recommended that you take one capsule of Prime Male at least four times per day. This should be accompanied by a glass of water and alongside a healthy meal or snack.

By enjoying Prime Male in such a regulated way, the body enjoys a carefully curated intake of nutrients to help boost testosterone levels specifically intended by the manufacturers.

Are there any side effects to Prime Male?

As of yet, there have been no reports of side effects of Prime Male. On the other hand, it is recommended that you take Prime Male exactly described in the section above.

This is because D-Aspartic Acid should be taken alongside food as the ingredient is known to cause upset stomachs if it is taken without anything to accompany its digestion.

How to get hold of Prime Male testosterone boosters

One box of Prime male costs £39 alongside shipping, which can come at an additional cost of £9.95 depending on your choice of courier.

For those looking for long-term results and big savings, a three-month package comes with an extra box of boosters and free shipping. As with all good natural testosterone boosters and supplements, Prime Male comes with a 90-day guarantee.

There are no discount codes for Prime Male, with the only discounts being featured on multi-box purchases direct from the official store.

Like many other supplements, neither does Prime Male offer free trials, as the booster takes at least 90 days to enjoy the full benefits of the product.

Wrapping up

Let’s take a look at the overall pros and cons when compared to other boosters on the UK market.


  • Great list of ingredients

  • All-natural

  • Avoids stimulants

  • Aimed at a wide range of men

  • Great for those aged 30+

  • 90-day money-back guarantee


  • Reminders required for regular consumption

  • Food or snacks required to avoid stomach issues

Prime Male is one of the most accessible testosterone boosters on the market and its list of carefully selected powerful and natural ingredients make it a sure market leader.

Supported by a league of positive reviews and conversations across social platforms, there’s little wonder why Prime Male makes it to the top of this list.

Hunter Test

Another big hitter from the bright minds of Roar Ambition, Hunter Test is designed for those who want to enjoy an edge in fitness and sports.

Scientifically created to give users the highest and safest possible testosterone boost, the supplement gives the body everything it needs for superior sports and fitness performances.

What are the benefits of Hunter Test?

If you're searching for sharpened sports performances, whether in the gym, on the track, or even in bed, you’ll be interested to know that Hunter Test offers a range of benefits, including:

  • A safe yet powerful boost in testosterone levels

  • An increase in both muscle mass and strength

  • A heightened libido

  • A boost in motivation

  • A boost in mood, focus, and mental agility

  • A rise in self-confidence

As with Prime Male, it is important to point out that Hunter Test is enjoyed and supported by a healthy diet and fitness regime.

What’s in Hunter Test?

Designed for maximum benefit to fitness fanatics and athletes, Roar Ambition has gone all-out to ensure that Hunter Test provides the best possible results. The ingredients, as listed on the label, are as follows:

  • Vitamin D3 (as Cholecalciferol) – 5000 IU

  • Vitamin K2 (as Menaquinone 7) – 150 mcg

  • Magnesium (as Magnesium Oxide) — 200 mg

  • D-Aspartic Acid – 3000mg

  • Asian Ginseng (Panax Ginseng) (root) (standardised to 5% Ginsenosides)  – 300 mg

  • Ashwagandha Extract (Withania Somnifera) (root) (Standardised to 1.5% Withanolides)  – 300mg

  • Indole-3-Carbinol – 200mg

  • Boron (as Disodium Tetraborate)– 10mg

Indole 3 Carbinol is a great mix to this list of ingredients as it inhibits the action of globulin (a sex-binding hormone) and therefore lowers the production of estrogen with the ultimate outcome of promoting healthy levels of testosterone. It can generally be found in a range of powerful foods including broccoli, brussels sprouts, and cabbage.

Another interesting and noteworthy ingredient is Vitamin K2, which helps to stop the build-up of calcium within the arteries, allowing Vitamin D3 to run more freely throughout the body.

While performing a supporting role to Vitamin D3, Vitamin K2 also supports calcium synthesis, which contributes to healthy and strong bone and muscle production.

When should you take Hunter Test?

It is advised that you enjoy Hunter Test three times per day with a dose of two capsules each time. As with Prime Male, Hunter Test is designed to be taken in such a way that the body enjoys a safe but regular amount of nutrients to amplify the body’s production of testosterone.

As Hunter Test also contains D-Aspartic Acid, it is advised that the booster is enjoyed with a meal or snack.

Are there any side effects to Hunter Test?

As of yet, there are no reported side effects from Hunter Test. As the booster is scientifically formulated, the product has gone through rigorous tests to ensure that it provides the best possible benefits in a safe and efficient way.

All the ingredients listed on the product label are natural, carefully selected, and come in their purest forms. What’s more, the formula contains zero additives, such as sugar, caffeine, or soy.

How to get hold of Hunter Test

You can buy Hunter Test on its official website, and there are three purchase options available.

A single bottle contains 180 capsules and costs £65 while two bottles cost £130. For those looking for the best possible results, Hunter Test is available to buy as a pack of three, which comes with an extra bottle and costs £195. All three options come with free UK shipping.

Like Prime Male, no other discount or free trial is currently available.

As with any other testosterone booster on the market, Hunter Test comes with several pros and cons, which we’ll summarise below:


  • Powerful, scientifically backed ingredients list

  • All natural with no additives or stimulants

  • Can relieve stress and improve confidence

  • Great for bodybuilders and fitness lovers

A testosterone booster aimed primarily at weightlifters, TestoFuel is yet another standout booster from Roar Ambition designed to help support healthy levels of testosterone within the body. 

As any bodybuilder will tell you, sticking to a well-balanced diet and hardy fitness regime is incredibly difficult, which is why many turn to the likes of TestoFuel for support.

As testosterone levels drop by 1% every year, this product is perfect for older men who want to sculpt their bodies to perfection.

What are the benefits of TestoFuel?

Aside from a healthy rise in testosterone levels, TestoFuel claims to provide a number of important benefits, including:

  • Increased energy levels

  • Strength gains

  • Muscle gains

  • Better sex drive

Of course, these benefits can only really come to fruition with a healthy diet and exercise regime, as with any booster or supplement.

What’s in TestoFuel?

To ensure that bodybuilders enjoy the best possible results, Roar Ambition has created a transparent formula of high-quality ingredients. As seen on the label, TestoFuel contains:

  • Vitamin D3 (as Cholecalciferol) – 100ug

  • Vitamin K2 (as Menaquinone 7) – 18ug

  • Magnesium (as Magnesium Oxide) – 70mg

  • Zinc (as Zinc Aspartate) – 10mg

  • D-Aspartic Acid – 2000mg

  • Panax Ginseng Extract (10:1) equivalent to 100mg

  • Fenugreek Seed Extract (33:1) equivalent to 800mg

  • Maca Root Extract (100:1) equivalent to 1800mg

  • Oyster shell (Mollusc)  – 100mg

  • Boron – 8mg

Aside from the more common (yet powerful elements) of the ingredients list, such as Vitamin D3, Vitamin K2, and D-Aspartic Acid, there are a few standout additions to the formula. 

Although the addition of oyster shells means that TestoFuel is not suitable for vegans, it is a clever addition as several clinical trials have found that oyster extract can inhibit estrogen while also improving testosterone levels.

What’s more, for those interested in improving their libido or performance in the bedroom, Ginseng not only promotes muscle protein synthesis but may also enhance fertility and male reproductive health.

Another notable addition is Boron, which is a trace mineral that is said to help conditions such as diabetes, and cholesterol, and help treat vaginal yeast infections. More importantly, however, several studies have shown that it might boost testosterone levels.

When should you take TestoFuel?

It is advised to take four capsules per day with meals. As advised by the manufacturer, one capsule should be enjoyed with breakfast, one accompanied by a snack, and one with lunch and another with dinner.

Like all of the best testosterone boosters, it can take at least two months to see noticeable results, so it’s important that you add TestoFuel to your daily diet and fitness regime as soon as possible.

Are there any side effects to TestoFuel?

As of yet, there are no reported side effects to TestoFuel. That said, the booster contains high levels of Vitamin D and Magnesium. Adult men should take no more than 4000mg of Vitamin D per day and 350mg of Magnesium.

How to get hold of TestoFuel

TestoFuel is available on Roar Ambition’s official website — Like all its other products, TestoFuel is not sold on Amazon or eBay. As with the previous boosters, there are no discounts or free trials on offer.

A month’s supply costs £45, while a two-month supply costs £90. Both options come with free shipping. Like other Roar Ambition products, TestoFuel offers a free bottle if you go for the three-month option at £135.

Additionally, if you choose the two or three-month option, you will receive a free Boss Workouts Program (worth £99), which includes video tutorials and detailed nutrition e-books.

Wrapping up

Let’s take a look at the pros and cons of TestoFuel when compared to other testosterone boosters currently available on the market.


  • Carefully created list of ingredients for bodybuilders

  • Cheaper than some testosterone boosters

  • Fully disclosed formula

  • Free delivery

  • Free workout program on two and three-month options

Elm & Rye Testosterone Support

A fresh testosterone booster from the American company, Elm & Rye, the booster claims to slowly help raise testosterone levels within the body in a natural and healthy way.

What’s in Elm & Rye Testosterone Support?

Unlike other manufacturers, Elm & Rye doesn’t provide information on the doses found within the booster, which means they’re part of a proprietary blend. Nevertheless, the ingredients are as follows:

  • Diindolylmethane (DIM)

  • Tongkat ali (Long Jack Eurycioma) root

When should you take Elm & Rye Testosterone Supplement?

According to Elm & Rye, you should take the supplement once per day, which is highly convenient if you struggle to keep up with your supplement or booster intake.

The company also recommends consulting a physician or nurse if you happen to be pregnant, are nursing, or have a prominent medical condition.

Are there any side effects to Elm & Rye Testosterone Supplement?

It is highly unlikely that Elm & Rye Testosterone Supplement will cause any side effects when enjoyed as part of a healthy diet and fitness regime. That said, the website does not provide dosage details, which means that it is hard to analyse whether there could be any notable side effects.
