Acknowledging your need for a testosterone boost only marks the beginning of your journey to restoring the masculinity of your youth. The tougher hurdle will be determining which testosterone supplement will work for you. And the options are vast. You likely do not have the time or budget to go through all of them. Nor do you want to subject your body to dozens of different testosterone boosters.  

Narrowing your selection to the leading and most reputable brands will certainly make your work easier. Still, you will have to make a choice. If you are looking for a good testosterone supplement, TestoPrime and Testofuel are bound to come up in your search. It’s hard to go wrong with either one. However, one brand will always score higher overall. We have taken a look at the attributes, pros, cons and pricing of the two brands to identify which product you should pick. Let’s go.

What is TestoPrime?

Formulated with the middle-aged man in mind, TestoPrime contains 12 natural ingredients that can raise your free testosterone levels by as much as 44 percent.

Made by Wolfson Brands, this supplement promises to recapture your youthful vigor, increase lean muscle mass, shred extra fat, quicken recovery, improve endurance and lift libido. 

TestoPrime also improves your physical and mental energy, self-esteem, and enthusiasm while lowering cortisol (stress hormone) levels. The end result is increased strength, lean physique, stronger erections, better sleep and sharper concentration. With TestoPrime, you’ll feel energized despite a long and exhausting day.


TestoPrime is a product of Wolfson Brands, a UK-based wellness and beauty company established over 10 years ago. It is now one of the best-known supplement makers with products addressing a wide range of wellness challenges. Apart from TestoPrime, Wolfson Brands makes Bauer, NooCube, Clear Skin Max, PhenQ, Eye Secrets, Hår Vokse, Proactol XS, SuperPower, XYZ Smart Collagen and YouTonics.

Key Features
  • Increases lean muscle mass
  • Strengthens libido
  • Lowers stress levels

What is TestoFuel?

TestoFuel is formulated to grow your bulk of lean muscle by increasing the body’s free testosterone levels. This testosterone supplement is made by sports nutrition experts Roar Ambition.

It works by stimulating the synthesis of muscle protein and ensuring the body has the building blocks it requires to grow muscle. But muscle buildup is not the only benefit Testofuel provides.

Testofuel also boosts strength, shreds fat (including the notoriously stubborn belly fat), lifts mood, raises confidence, nurtures self-drive and contributes to recovery.

Plus, Testofuel helps regulate insulin and glucose, which is vital for fat loss. 

Testofuel is produced from clinically researched and extensively tested natural ingredients. While suitable for all men, it is most effective among older men trying to get back the vitality of their younger years.


Testofuel is a product of Roar Ambition, a UK-based sports and wellness nutrition company established in 2014 and is headquartered in Leeds. It is a leading player in the wellness industry. 

The company's success can largely be attributed to the exponential growth in sales of its flagship product, Testofuel. The visibility Testofuel provided in the fitness and wellness community became a launching pad for the other brands in the Roar Ambition stable such as Hourglass Fit, Prime Male, Hunter Burn, Instant Knockout Cut, Hunter Test and Hunter Focus.

TestoPrime and Testofuel have identical quantities of d-aspartic acid. 

TestoFuel contains 150% more panax ginseng and nearly 300% more vitamin D. Panax ginseng contains antioxidants that improve energy and libido while fighting off fatigue. Vitamin D lifts testosterone levels, increases muscle mass and boosts strength.

TestoPrime has 300% more fenugreek and 300% more zinc. Fenugreek is rich in magnesium, zinc and selenium. It inhibits SHBG (sex hormone binding globulin) thus ensuring higher levels of free testosterone. Zinc is one of the most important minerals for male reproductive health; its functions include lifting testosterone levels and slowing the conversion of testosterone to estrogen.

Unique Ingredients in TestoPrime

  • Ashwagandha: Fosters fertility, lean muscle growth, fat shredding, energy boost, efficient digestion and cognitive capability.
  • Black pepper: Improves the absorption of the supplement’s other ingredients.
  • Garlic: Increases free testosterone, improves metabolism and speeds up weight loss.
  • Green tea: Contains compounds that block conversion of testosterone to the destructive dihydrotestosterone (DHT). High levels of DHT have been associated with prostate problems and hair loss.
  • Pomegranate: Contributes to efficient blood flow leading to higher stamina, stronger sex drive and lower fatigue.
  • Vitamin B5: Supports the conversion of excess fat to energy. It speeds up weight loss and regulates testosterone levels.
  • Vitamin B6: Helps production of hemoglobin, supports heart health and regulates testosterone levels. It lifts energy, lowers fatigue and improves brain function.

Unique ingredients in Testofuel

  • Boron: Increases testosterone level and enhances vitamin D’s effectiveness.
  • Maca root: Increases pre-workout and post-workout endurance and stamina. It also strengthens libido, lifts mood, fosters relaxation and enhances sleep quality.
  • Magnesium: Boosts endurance, lifts metabolism, increases strength, speeds up workout recovery, grows lean muscle and improves the quality of sleep.
  • Oyster extract: Long recognized as an aphrodisiac, oyster is rich in zinc. It elevates free testosterone levels and improves reproductive ability.
  • Vitamin K2: Enhances vitamin D effectiveness.

Side Effects

TestoPrime and TestoFuel are formulated from clinically researched and extensively tested natural ingredients. The average person is therefore unlikely to experience any side effects as long as the supplements are taken according to the manufacturer’s recommended dosage.

Still, no two people’s bodies are identical in their biochemical composition. So, it is vital that you talk to your doctor before you start using a testosterone booster. This is particularly important if you suffer from prostate disease, cardiovascular illness, any long-term medical condition or are on medication.

Final Verdict

People have different reasons for taking testosterone boosters. And no single testosterone supplement brand works best for everyone. Some people will find more success with TestoPrime, others with Testofuel. Still, this comparison gauges the two products in the context of the average person. And in this respect, TestoPrime does appear to be the better product.

First, while Testofuel has more panax ginseng and vitamin D per serving, TestoPrime has four times as much zinc. Zinc is one of the most important elements in male reproductive health and even a seemingly small deficiency in this mineral has a significant effect on levels of free testosterone. The zinc in TestoPrime is complemented by the fenugreek which blocks the action of SHBG.

Second, TestoPrime has a more diverse ingredient mix. This makes it more likely that key pain points of testosterone deficiency will be addressed.

Third, TestoPrime has a better pricing and offers proposition. It costs less per bottle, has bulk discounts starting from two bottles, offers free shipping on all orders and has an ambitious lifetime money back guarantee.

Fourth, TestoPrime is vegan-/vegetarian-friendly.
