Best Testosterone Supplements UK

Read my extensive guide to the best testosterone supplements and T boosters available on the market in the UK today.

Getting older is no fun for men or women. In men it’s your testosterone that gets lower meaning that your sex drive reduces and your ability to create and keep muscle gets harder. Men also increase the amount of oestrogen they have in their body, with the reduction in testosterone is one of the reasons men develop man boobs or moobs – because of the imbalance of hormones.

7 of the Best Testosterone Supplements to Buy in UK – At a glance

  1. Testogen
  2. Brutal Force SBulk
  3. Hunter Test
  4. Testo Prime
  5. Testo Lab Pro
  6. TestoFuel
  7. Prime Male

I’ve put together a list of the Best Testosterone Boosters available to buy so you don’t have to look too far to find them.

1. Testogen

Testogen boosts your testosterone naturally and reverses the symptoms of low T.


What I like:

  • 100% safe and natural ingredients backed by clinical studies
  • Helps with energy levels and mood
  • Can promote muscle growth

Testogen is yet another oldie, but goodie in the testosterone boosting industry. True to its veteran status, Testogen makes use of a really traditional testosterone formula made with herbs and common vitamins and minerals. It’s not the most premium formula out there in terms of forms used or branded ingredients, but it does get the job done for testosterone. Standout ingredients include Zinc, D-Aspartic Acid, and Vitamin D3, three ingredients heavily studied for their positive effects on testosterone levels.

On top of having a great formula, Testogen manages to keep their overall formulation (including fillers) synthetic-ingredients free. No artificial colour or flavour included.

2. Brutal Force SBulk

From the huge range of Brutal Force supplements made in the UK and USA.

Brutal Force SBULK

You’ll like:

  • Potent testosterone ingredients
  • Contains Boron, Zinc, and Bioperine
  • Tried and testes testosterone formulation
  • Good value for formulation and number of servings
  • Money back guarantee

Brutal Force SBULK is described as the original bodybuilding supplement and the manufacturers claim their product can boost testosterone levels, help you build more muscle without fat, prevent muscle loss, and even speed up lean muscle mass recovery.

The formula for SBULK is designed to specifically mimic Sustanon 250, a steroid prescribed to men with male hypogonadism – a condition that impairs testes function – without the side effects.

3. Hunter Test

Contains D-Aspartic acid and Zinc. Premium formula, 100% natural ingredients with 90-day guarantee. Can help with sex drive and give improve energy levels.

Hunter Test

Benefits include:

  • Great value for money
  • Potent ingredients for boosting testosterone levels
  • Helps with stress
  • Boosts sex drive and fertility
  • 100% natural testosterone production

Hunter Test is made by the same company behind the famous TestoFuel: Roar Ambition. The key difference between Testofuel and Hunter Test is whom they are marketed for.

TestoFuel is formulated for the younger athlete or fitness enthusiast who wants to take advantage of their still robust testosterone levels for maximum muscle growth and strength boosting. Hunter Test was made for the not-so-young lifter who wants to remain within a healthy testosterone range. They may also be having problems with keeping testosterone up, or maybe having problems in bed.

Hunter Test’s ingredients are in their premium forms. This tells us the attention to detail and their drive to satisfy customers when it comes to providing ingredient synergy and potency.

4. Testo Prime – New for 2021

A great combination of all the vitamins and minerals needed to boost your T levels


What you’ll like

  • Standardised ingredients
  • Black pepper for maximum bioavailability
  • Popular testosterone herbal
  • Gives you more energy

Testo Prime has been in the testosterone boosting business for years, but they decided to have a reformulation for 2021, and I think it’s definitely premium. The ingredients boast of premium versions of popular testosterone ingredients like Zinc, Ashwagandha, and Black Pepper. Then, it also contains Garlic and Green Tea, two ingredients you don’t always see in testosterone supplements but do have legit reasons especially when it comes to antioxidant and inflammatory benefits.

It’s not a perfect formula, however, since the synergy is a bit off, and they added an ingredient that’s not really pro testosterone.

Despite some of its shortcomings on overall ingredient potency and synergy, I think Testo Prime’s benefits outweigh the drawbacks.

5. Testo Lab Pro T-Booster

Caffeine free and Vegan-friendly. Gluten Free and Soy Free.

Testo Lab Pro T-Booster


  • Premium formulation
  • Complete testosterone blend of vitamins and minerals
  • Potent ingredients

Testo Lab Pro T-Booster is one of the most premium formulas I’ve ever had the opportunity to review. I shouldn’t have been surprised, however, since it’s made by Opti Nutra, one of the world’s leading supplement companies known for their premium products. True to their theme, Testo Lab Pro T-Booster contains powerful testosterone ingredients, all of which are in their best and highly bioavailable forms. The formula is definitely capable of long-term testosterone health benefits with an added touch on muscle growth and stress management on the side.

However, the premium feel definitely comes at a premium price, but if you’re looking for a product made by a company known to be one of the best, the price may not look as steep.

6. TestoFuel

From the Roar Ambition Supplements range, TestoFuel is formulated for younger men. Contains Zinc and D-Aspartic acid. Can help with building muscle.

Testo Fuel

Benefits you’ll like include:

  • Highly reputable company
  • Traditional formula that works
  • UK and USA facilities
  • Transparent label
  • Money-back guarantee

TestoFuel is an old player in the testosterone game, and it doesn’t seem to be losing merits anytime soon. What makes it so highly regarded is how the formula manages to stay rooted in tradition, avoiding the fancy new shiny objects and focusing on what’s been known to work for decades. Despite the formula being “old,” it’s still premium in form and potency. In fact, a lot of testosterone booster fans swear by TestoFuel’s efficacy when it comes to their workouts and muscle mass gains.

Testo Fuel is also one of the few remaining testosterone products that still makes use of oyster extracts. If you’re after that ingredient, look no further than one of the best there is to ever use it.

7. Prime Male

All natural ingredients. Contains D-Aspartic Acid, Bioperine® black pepper and Vitamin D.

Prime Male T Booster

You’ll like:

  • Excellent customer service
  • Premium formulation
  • Transparent label
  • Real testimonials

Prime Male has been one of the best in the business of boosting testosterone levels and with good reason. It’s powerful, potent, premium, and well-known in the testosterone boosting industry. Many fans praise Prime Male for being high quality and having effective formula synergy, especially with how the formula manages to add some of the best testosterone ingredients in the industry without sacrificing dosages for each one.

The formula is both traditional and definitely outstanding, but what separates it from other amazing competitors is the presence of D-Aspartic Acid Calcium Chelate. This form of D-Aspartic Acid is more bioavailable, making it much more potent.

What is a Testosterone Supplement?

Sometimes known to as a ‘T Booster’ or just ‘test booster’ these are referred to as a type of dietary supplement containing a range of ingredients like amino acids, minerals, vitamins and herbal extracts.

Whilst there are a quite a number of testo products available in this health category there some that just aren’t as good as they claim to be.

How to take a T Booster

Most T boosters come in capsule or pill form, and are meant to be taken with water much like you do a multivitamin.

However, some T boosters are available in powder form and are usually flavoured which are mixed with water before drinking.

Remember: It’s important to always read the manufacturer’s guidelines on what dosage and quantity to take with each product.

In most cases testo supplements capsules allow to you take between 2 and 6 per day but this will depend on the level of ingredients and strength of the formulas and doses.

Testosterone Supplement Side Effects

Whilst most testo supplements ingredients are blends of minerals and vitamins in the main, it is always advisable to seek professional medical advice from your doctor before taking any new supplements.

Some people may experience side effects from other ingredients in the supplements they take, so it’s always advisable to read the list of ingredients before you buy.

Always check ingredients for items that you may be allergic to, and if in doubt, speak to your doctor first.

If you are pregnant or breastfeeding or are under the age of 18, you should not take an supplements, especially if you have any underlying medical conditions or are taking any medication, without having first consulted a certified medical professional.

How do Testosterone Supplements Work?

Testosterone boosters are supplements that help men increase their natural testosterone level. These kinds of supplements don’t exist to help you get jacked beyond belief or to send your testosterone level sky-high. They’re not steroids, and they don’t include any natural or synthetic form of testosterone. Instead, testosterone boosters work by design to increase testosterone back to baseline using natural ingredients, so you can feel stronger, sharper, and more like your younger self in the gym, the bedroom or just generally.

Each supplement will increase testosterone production in different ways directly influenced by the manufacturer’s formula. Some include ingredients that increase your testosterone production directly. Others work by blocking oestrogen to stop your testosterone from being converted.

It goes without saying that every product is different. Some manufacturers add ingredients in doses that are clinically proven to raise testosterone levels in otherwise healthy men. Some brands are snake oil salesmen that throw together a list of ineffective (but usually not harmful) ingredients for men who want to feel like they’re 19 again.

Knowing what’s in each testosterone booster and whether it’s clinically effective is the key to not finding yourself a victim of daylight robbery. These pills aren’t cheap. So, you don’t want to throw away a few hundred quid on something that the manufacturer knows doesn’t work.

Before you go any further in this guide or on your search for a testosterone booster generally, every man should know this.

Testosterone boosters won’t do your erection any favours. If you’re struggling to get it up or keep it up, then science says it’s actually highly unlikely that your problem has much at all to do with your levels of testosterone or how ‘virile’ you feel. You may want to consider getting a testosterone level home test to actually see if your levels are low or not.

If your sex drive problem is chemical, it’s far more likely to be related to high blood pressure or high cholesterol. So, if you’re curious about testosterone boosters because you think you might have erectile dysfunction (ED), go see your doctor first. Despite their marketing messages, low testosterone has no impact on ED.

Increasing testosterone

Some of the best testosterone boosters will either increase testosterone production, or help to reduce the amount of it that is converted into oestrogen. There have been multiple studies on the effects of these boosters. Some studies have been conducted specifically to see the effects and benefits on the body’s natural production of testosterone and some studies have noted the increase in testosterone levels as part of a wider study into the effect of taking a booster for other things such as cancer treatments.

Natural Testosterone Boosters

The human body is a complex and unique thing, what works for one may not work for another so some of the use of testosterone boosters may work for you and some may not. All can be found naturally in vitamins and minerals from food or supplements, even in the skin when you go out into the sun, but the levels required to boost testosterone production might need you to move to a sunnier location or to eat a boat load of broccoli and let’s face it, no-one really wants that (or the aftermath)!



Found in: Nuts, seeds, legumes.
The benefits: Magnesium is involved in hundreds of biochemical reactions in your body and may help to boost exercise performance. Can also help to lower blood pressure.



Found in: Natural herb.
The benefits: Can reduce cortisol levels and may help reduce stress and anxiety. Can also boost testosterone and increase fertility in men.

Zinc found in seeds


Found in: Seeds, oysters and beef liver.
The benefits: Zinc is one of the most common ingredients in testosterone boosters. Why? Because some people believe that having additional Zinc in a supplement has been shown to increase testosterone levels significantly and that restricting zinc intake has lowered testosterone levels. As your zinc intake goes up or down, so do your testosterone level.



Found in: Natural spice and root.
The benefits: Has anti-inflammatory properties and aides stomach upsets, as well as helping to reduce risk of diabetes.



Found in: Naturally occurring herb
The benefits: Can help to balance cholesterol and maintain healthy liver and kidney function.

Vitamin D in Fish Oil Capsules

Vitamin D

D-Aspartic Acid in Milk

D-Aspartic Acid

Found in: Milk & dairy, fish, meat and eggs
The benefits: Involved in the production and release of testosterone in the body.

What Causes Men’s Testosterone Levels to Fall?

While testosterone is vital, falling testosterone levels aren’t strictly much to worry about, and can be in fact as natural as discovering a grey hair or two. According to the NHS, it should cause no alarm for men in their 30s to experience a 2 per cent drop in their testosterone levels each year.

When genetics are not causing low testosterone is when you may have a problem. Often, falling testosterone levels that can’t be attributed to biological reasons can be linked to either poor lifestyle or mental health issues.

If you’re experiencing erectile dysfunction or low libido – symptoms of low testosterone levels – then it may be worth exploring with your doctor whether stress, depression or anxiety could be the cause.

Now, if lifestyle or psychological problems aren’t at fault for your low T-levels, then the other possible cause is hypogonadism, where the testes produce few or none of the normally naturally occurring hormone. Men can be born with hypogonadism, or otherwise it can be developed in later life, as a result of injury or infection most commonly.

Lifestyle Choices to Boost Testosterone Levels Naturally

Leading a healthy lifestyle is a sure-fire way to boost testosterone naturally. While these tips won’t lead to a sudden increase (and on their own may not be enough to increase your levels to a point you’re happy with), they will give you at least healthy, normal levels of the hormone.

There’s nothing earth shattering about these guidelines, though they are still worth highlighting:

  • Strength training – A strength training regime which puts your muscles under strain is a great way to provide stimulus for your body to increase natural testosterone production. Increasing your muscle mass leads to the body producing more testosterone naturally.
  • Balanced diet – Sticking to a balanced nutritional plan, which includes eating foods rich in vitamins, minerals and natural amino acid, as well as maintaining healthy blood sugar levels, is a key method to increase your T levels.
  • Avoid alcohol – Our testosterone levels can be affected by certain types of alcohol. Beer, in particular, has a negative impact due to its phytoestrogen and prolactin content which are typically associated with increasing the levels of the female hormone estrogen.
  • Sleep – Sleep is a critical function not only to maintain a healthy immune system, but to enable our bodies to repair and recuperate, helping the body to produce acceptable levels of testosterone for things like maintaining and increasing muscle mass.
  • Natural sunlight – Getting outside into the sunshine is known to be a great source of Vitamin D, whose benefits include healthier bones, muscles and levels of testosterone.

Are Testosterone Boosting Supplements Safe?

Doctors will tell you that approved supplements bought from reputable businesses are almost always going to be safe, provided the manufacturer’s instructions are followed. That means you need to buy your supplements from a company that manufactures product in the UK to current standards set out by the FDA and FSA. Products marked with cGMP will have been manufactured in a facility that has been regulated to the Current Good Manufacturing Practice standards required by the FDA.

So we have to ensure that the product we buy is manufactured in a safe environment but does that mean it is safe to take? It is easy to say that if you take more than the recommended levels that this will cause harm, but it is essential that you only take the correct amount, especially if you are mixing supplements together, such as fat burners and testosterone boosters. The best advice is to make sure that you are aware of the levels of ingredients in both and make sure that you are not taking too much.

Thinking that simply taking more of something that is perceived to be good for you or because it does something taking more will help it to do more – like taking more fat burners or taking too many testosterone boosters, they won’t boost more testosterone, probably just get stuck in the liver and cause damage.

Most of these testo supplements have been specially formulated to make sure that the levels of each ingredient works best with each other, so taking more of one element might have an effect on another ingredient in the mix, making it either more powerful or potentially more harmful.

Common Myths

In 2021 men’s health is something that is not embarrassing or kept quiet, celebrity alpha males like Joe Rogan openly talk about taking testosterone therapy treatments to help with increasing their testosterone levels as well as things like sex drive.

The impact of low testosterone can be many fold and your testosterone levels will naturally decline as you age. Men taking charge of their levels of testosterone through simple supplements seems like a no-brainer.

There is a common myth that taking supplements for Testosterone can cause prostate cancer, there are meta studies that have been conducted that show there is no evidence that this is true. On the flip side, low testosterone as well has been shown to have no correlation with prostate cancer either. As prostate cancer is one of the most common in men, this is very reassuring.

Another myth is that Testosterone therapy will fix erectile dysfunction; the truth is that it will help with sex drive and your overall sexual health which can have a knock-on effect on erectile dysfunction.

Guide to Buying Testosterone Boosting Supplements

A bit simplistic I know, and it doesn’t help anyone wanting some sort of proof that these supplements work, so here is a quick guide to buying testosterone booster supplements:

  1. Only buy supplements from reputable suppliers – make sure that the company you are buying from has reviews on websites like this, that they fully disclose what you are buying.
  2. Don’t buy propitiatory blends where you are not told what is in the supplement because the company doesn’t want to disclose it. You don’t know what is in it and what harm it could do you.
  3. Check if the supplement has been tested by people like you (comparable age, sex). Read testimonials on websites like this or the manufacturers website, believe them or don’t but steer clear of companies who don’t show any reviews (unless it’s a new product).
  4. Look for warnings on the label and read the small print – for example, people with heart conditions would want to check the supplement is not toxic for the heart or that you can take the supplement if you are pregnant.
  5. Look at the ingredients and think about what you are taking if you want to use multiple supplements at the same time.
  6. Never exceed the stated dose, ever.


Testosterone levels reduce with age. Between 20 and 25 years, levels are at their peak. Eventually, at 30, levels start to decrease. For men aged between 30 and 55 especially, testosterone boosters help enhance levels of free testosterone.

Despite a rigorous workout and having a healthy balanced diet, if you can’t lose the body fat and are unable to build lean muscle mass, then using a testosterone booster can help.

Furthermore, sexual performance issues like the inability to sustain erections and reduction in sex drive can be addressed with testosterone boosters. The supplements provide nourishment and contribute towards fixing your hormone levels.

The recommended dosage boosts testosterone by 30% or up to 50%. Before deciding to start taking a testosterone booster, speak to a doctor, especially if you have a medical condition, and take other medications.
