Testosterone boosters have been available as supplements for a while. They optimize testosterone production in one’s body, which in turn will translate into better performance at the gym, more muscle gain, and increased libido and sexual function, therefore improving the quality of one’s sex life. 

Two premium players on the market — TestoPrime, and Testofuel — have been getting a lot of attention. 

With how confusing it can get to choose a reliable option in a sea of choices, we decided to do the leg work for you. We’re here to present our findings and help you make a choice from a position of knowledge.

What type of products are TestoPrime and Testofuel?

TestoPrime and Testofuel are all-natural testosterone boosters made with natural ingredients and no synthetic compounds. 

They’re marketed for men who are looking to make a drastic change to their physique by reducing their weight and also regain control in the bedroom. 

Each product has its intended use, distinct blend of ingredients, and unique benefits and advantages based on those ingredients.

Who are the respective manufacturers?


Established in 2008, Wolfson Brands — a UK-based company — is the manufacturer of TestoPrime. 

With products targeting a variety of wellness issues, it is currently one of the leading supplement manufacturers. Wolfson Brands also manufactures Bauer, Clear Skin Max, NooCube, Eye Secrets, Proactol XS, PhenQ, XYZ Smart Collagen, Har Vokse, SuperPower, and YouTonics in addition to TestoPrime.


Roar Ambition, a sports and wellness nutrition company with headquarters in Leeds and a presence in the UK, is the manufacturer of Testofuel. Being Wolfson Brands' competition, It is a dominant force in the health and wellness sector.

The company's phenomenal growth in sales of its flagship product, Testofuel, is largely responsible for its success. Prime Male, Hourglass Fit, Instant Knockout Cut, Hunter Burn, Hunter Test, and Hunter Focus are just a few of the products owned by Roar Ambition that benefited from Testofuel's notoriety in the fitness and wellness industry.

The benefits


TestoPrime's primary purpose is to boost your testosterone and then maintain its future production through the processes of biochemical adaptation. 

The company's website claims the following:

  • 44% level increase in testosterone production;
  • 12% higher rate conversion of fat into energy. Consequently, weight-loss attempts are improved for a visibly reduced abdomen;
  • 71.6 % reduction in stress by inhibiting the harmful effects of prolonged exposure to cortisol — weight gain around the abdomen, bloating, etc., which results in a slimmer and fitter figure;
  •  The natural blend supports a consistent and healthy flow of testosterone, which acts synergistically to encourage a better fat-burning mechanism; therefore increasing the breakdown of body fat by up to 16%;
  • 12% higher fat-to-energy conversion which in turn aids further in any user’s weight-loss efforts;
  • Increased muscle strength thanks to the improved blood flow made possible by the ingredients’ synergy and effects on the body.


Testofuel is marketed as a natural testosterone booster for people looking to enhance their physical appearance, increase muscle mass, lose belly fat, and, overall, aim to get the Hollywood superhero look. 

Therefore, its ingredients work together to achieve exactly that. Testofuel raises and maintains testosterone levels principally through the use of D-Aspartic Acid and Ginseng. 

Additionally, it gives a quick-to-medium-term boost in vigor and virility that might be crucial to how you feel during times of increased stress and hardship.

The combination of ingredients works wonders for boosting your energy, mood, and more, especially while you're mentally and physically tested.

Here’s a quick rundown of its benefits: 

  • Increases lean muscle mass while shedding fat (belly fat included);
  • Enhances recovery and strength;
  • Promotes self-drive, boosts confidence and mood;
  • Since it doesn't include any stimulants, like caffeine or other negative substances, it is superior to steroids.

Section Winner - TestoPrime

If we're talking longevity, TestoPrime wins this section. It focuses on prolonging your teste's ability to produce testosterone compared to the short-term benefits of TestoFuel.

If we’re addressing performance at the gym, users have been confessing their frustration with TestoPrime and how long it takes for them to see results compared to Testofuel.

If we’re talking overall, TestoPrime takes the cake. TestoPrime contains a long list of ingredients that improve your physical, sexual, and mental wellness, whereas TestoFuel solely concentrates on enhancing your physical attractiveness.


Ingredients they have in common 

D-Aspartic Acid

It is vital to support the regions of the brain that control hormone production, specifically luteinizing hormone (LH), a Testosterone precursor secreted by the pituitary gland that essentially instructs the testes to produce more Testosterone.


Was first discovered to have a direct impact on testosterone levels in addition to its traditional uses as an aphrodisiac and libido booster.According to one study, using the herb for a brief time raised testosterone and its powerful byproduct, DHT.


Rich in zinc, magnesium, and selenium, it has the power to inhibit sex hormone binding globulin (SHBG), a substance that swallows up testosterone, leaving little available for the body's tissues.


Is an essential mineral and has the ability to raise levels of luteinizing hormone.

According to recent studiesa diet deficient in zinc is detrimental to testosterone levels because a zinc shortage renders androgen (a group of sex hormones) receptors ineffective.

TestoPrime original ingredients

  • KSM 66® Ashwagandha Extract

    Shields testicular cells from oxidative stress and damage. Less damage to the testes may support testosterone levels as the testes are where the majority of testosterone is created. Ashwagandha has also been shown to boost luteinizing hormone synthesis.

  • Green tea extract

    Epigallocatechin gallate chemicals (EGCG), which are components in green tea, have been proven to have the power to prevent testosterone levels from dropping by preventing the conversion of healthy testosterone to dangerous Dihydrotestosterone (DHT — a sex hormone).

  • Pomegranate Extract

    Is rich in antioxidants, which have been shown to improve the sex lives of both men and women. It can also boost testosterone levels, enhance the quality of sperm, and improve mood and sex drive.

  • Black pepper extract

    Is used to smoothen the absorption of the rest of the ingredients.

  • Garlic extract
    According to a systematic review of 18 studies, garlic's antioxidant characteristics can improve the structure of the testicles, boost testosterone levels, and promote fertility & spermatogenesis (sperm production).
  • Vitamin B5

    Supports the process of converting extra fat to energy. It controls testosterone levels and expedites weight loss.

  • Vitamin B6

    Controls testosterone levels, maintains heart function, and aids in hemoglobin formation. It increases vigor, lessens fatigue, and enhances mental performance.

Testofuel original ingredients

  • Oyster Extract

    Oyster extract is known to stimulate the secretion of bile and amplify liver functions, therefore cleansing the liver.

  • Magnesium

    This necessary mineral functions in the organism as a cofactor. Co-factors are necessary substances to activate enzymes. Magnesium is involved in multiple enzymatic processes, including those that control the heart, bones, and brain.

    It helps boost muscular endurance and metabolism and controls how much power and force your muscles can produce.

  • Vitamin K2

    It assists in increasing hormone release directly and indirectly. According to one study done on rats, 5 weeks of taking vitamin K2 supplements resulted in a 70% increase in circulating testosterone levels.

  • Boron

    Each dose of TestoFuel has 8 mg of boron in it. A 2015 study indicated that this quantity raised free testosterone levels by about 25%.

    Another study demonstrated that boron supplementation increases the potency of Vitamin D, another crucial component of Testofuel and an excellent natural testosterone activator.
  • Maca

    A 2002 study found that maca increased male sexual desire and a 2008 study found that it reduced postmenopausal women's sexual dysfunction.

    Additionally, while a 2006 study revealed higher sperm count in rodents, a smaller 2001 study found that daily use of maca over a four-month period boosted semen output in nine men

Section Winner - TestoPrime

The amount of d-aspartic acid content in TestoPrime and Testofuel is the same.

TestoFuel has nearly 300% more vitamin D and 150% more Ginseng. Antioxidants included in Ginseng boost libido and vitality while battling fatigue. Strength, muscle mass, and testosterone levels are all increased by vitamin D.

For gym performance, Testofuel takes the win.

On the other side, fenugreek and zinc are more abundant in TestoPrime, as much as 300%. Magnesium, zinc, and selenium are also present in fenugreek itself. As discussed earlier, fenugreek inhibits SHBG, resulting in greater amounts of free testosterone in the body. Furthermore, one of the most crucial elements for male reproductive health is zinc, which increases testosterone levels and reduces the rate at which testosterone is converted to estrogen.

When it comes to virility and sexual performance, TestoPrime comes out on top. 

Who are they intended for?


TestoPrime is intended for men who are having problems in the bedroom as well as those experiencing issues with energy and stamina.

The clinical trials and studies outlining the effect of garlic extract, pomegranate extract, and Ashwagandha extract (along with other ingredients) confirms this. 

It’s definitely not a product for those looking to increase their lean muscle mass or improve their physical appearance quickly.


Testofuel is also intended for men. If you’re looking to shed stubborn belly fat, enhance your performance at the gym, or increase your strength and endurance, this product might help you out.

Still, it cannot replace diligence and a balanced diet. The product is designed to provide healthy men a helping hand and improve the results of their training, not replace training completely.

Keep in mind that the benefits take time to manifest. Most men begin to see improvements in three to four weeks, but it takes several months of consistent use to reach peak condition.

Section winner - Tie

There is no section winner. There are, however, specific use cases for each product. TestoPrime is reserved for men looking to enhance or regain their sexual prowess and virility.

In contrast, Testofuel is reserved for men looking to achieve top physical condition and finally find that 6-pack. 

Potential side effects


TestoPrime is made from 100% natural ingredients, which is usually taken at face value as being safe for consumption. The dosage makes all the difference, though, but the dosage for the listed ingredients is well within the safe zone. So, all-in-all, there should be no side effects from taking TestoPrime.

Still, TestoPrime users should not exceed the recommended dose (number of tablets per day) hoping to multiply or increase its effects. That’s not how biochemistry works. High doses of any natural substance can lead to unwanted side effects, especially if you suffer from chronic health conditions. 

To be on the safe side, contact your doctor and take their clearance before starting TestoPrime.


Like Testoprime, Testofuel is also made of natural ingredients. This means the product is safe according to its biochemical composition, but they’ve also ensured the dosage is safe.

While you shouldn’t experience any side effects on Testofuel, our bodies' biochemistry can be different from person to person, and any persistent health conditions may have a role to play. It's recommended to consult with your doctor, especially if you have a cardiovascular condition or suffer from prostate issues. 

You should also ask your doctor’s permission if you’re on any sort of medication.

Section Winner - Tie

It’s a tie. Both testosterone boosters are made from natural ingredients in a controlled environment and accredited facilities. 

As long as you take the recommended doses and consult with your doctor if you’re taking any medication, you should be good to take any of the two products.

Customer reviews and experiences


TestoPrime’s review page holds a compilation of satisfied customers that are above the age of 30. Most of them mention how the product helped them gain more energy throughout the day.

That makes sense since — based on the research backing the ingredients — the product helps primarily with endurance, sexual prowess, mental clarity, focus, and last (and least) strength.

Here are a few testimonials:

“Since I’ve been taking TestoPrime I definitely have more energy to play with my kids, am less stressed and I feel much happier in myself. This supplement is a game-changer.” — Matthew Clarke

“TestoPrime works. Not only does it help with recovery and strength I feel like my day to day I’m way more focused on daily tasks.” — Daniel Ortiz

“If you need energy, or your job requires additional energy, This one is a Must!” — George Herrin


This product is the most used by people in the 25–35 age range. There are countless examples of people changing their bodies using this product to facilitate the process. It is also important to take into account the bodybuilding community's support for the supplement. Even the 6-time Mr. Olympia winner Robby Robinson takes Testofuel.

Contrary to TestoPrime’s testimonials page, Testofuel has before-and-after pictures of muscular and shredded men all over. 

Here are some of their reviews:

“When I first started taking TestoFuel I was skeptical, but within the first week I felt the system working. I was much more active and motivated to hit the gym, and because the results were there I had the mentality to keep going to the gym again and again and again...I was able to see surprising results within a week, and a month later I'm feeling amazing and looking very close to my goal.” — Cyrus Sadeghi

“I've gained almost 2 inches on my arms, over 3 inches on my chest and I'm more ripped. My abs look better than ever and I feel more motivated, I have more energy and I have better bigger lifts. My bench press alone went from 315 pounds to 365 pounds in less than 3 months!!!” — Brenon Bodkins

“I started feeling amazing in the gym and my mind and muscle connection was off the chain. I never believed in a magic pill but TestoFuel is close to that, it's a natural mood enhancer both in the bedroom and weight room.” — Ian Johnson

Section Winner - TestoFuel

The customers of both products seem to be satisfied. TestoPrime and Testofuel are testosterone boosters, but they also have additional benefits that segment their customer base demographically (by age). 

It’s worth mentioning that some of the 25-35-ish users of TestoPrime complained about how long it took them to see strength, gains, and overall physical appearance results since they started taking the supplement.

There is no apparent winner in this section, but if we were to use performance at the gym as the primary rating factor, Testofuel wins this round.

Price And Packages


TestoPrime comes with three offers, all of which include free shipping and two of which come with distinct benefits.

The cheapest option is, unfortunately, the option with the least value. It’s one bottle containing 120 capsules (4 capsules/day) for the price of $59.99 — the same in euros. Their best-value option is a buy-2-get-1-free for $119.99 which also includes free workout and nutrition ebooks. 

Lastly, their biggest-savings option is a 6 months supply (buy 3, get 3 for free) for $179.99 which also includes the free ebooks.

Testofuel’s pricing is different from TestoPrime’s. The company also has different offers, yet they both offer free delivery.

Their support pack contains a 2-month supply with a free program called “Boss Workouts: Lean Mass” for $130 — €110.

Section Winner - TestoPrime

Based on the offers and the pricing, there’s a clear section winner here and it’s TestoPrime. Their “most-savings” offer is clearly better:  TestoPrime with a  6-month supply for $179.99 compared to Testofuel’s 3-month supply for $195. 

Even when looking at their best-value offers: TestoPrime offers a 3-month supply for $119.99, while Testofuel offers a 2-month supply for $130.

Additionally, when comparing the values in Euros, TestPrime comes out as a clear winner.

Final Verdict: They both do their own thing well!

There is no clear winner here. 

Both products are marketed similarly, yet they’re not intended for the same target audience. Due to this, it would be weird to say one is better than the other. 

Both of these supplements are excellent when used properly, but they shouldn't be used in the same way.

In conclusion, TestoPrime is the top product for boosting your sexual drive, energy, and endurance. This is the ideal choice for you if your goal is to enhance your health and way of life rather than gain muscle.

On the other hand, there is absolutely no debate about which one will help you get in shape. TestoFuel is a great supplement for people who are serious about their health and fitness and want to see improved progress in the gym.
