Prime Male vs Testofuel 2024 | Which One Is Better?

bottles of Prime Male and TestoFuel side by side

For most men past their 30s, testosterone deficiency is an inevitable reality that brings fatigue, low libido, and many other life-changing symptoms with it. 

While low T cannot be avoided, testosterone boosters — like Prime Male and TestoFuel — claim that it can be reversed. Both promise to naturally bring your T levels back to normal with zero side effects, but which of the two is better for you? 

Let’s take a closer look at the benefits these T-boosting supplements offer to find out.

Distinct features

The features that set these testosterone boosters apart are:

Overall Rating: 4.7/5

  • Can return testosterone back to normal in weeks.
  • Helps you overcome fatigue by increasing energy.
  • Shifts your libido in high gear.

Overall Rating: 4.7/5

  • Faster muscle growth with increased muscle strength.
  • Accelerated reduction of excess body fat.
  • Enhanced mood and motivation for working out.

What is Prime Male?

Prime Male testosterone boosting supplements promise to turn the clock back on male aging. In their own words, “Just taking Prime Male by itself is enough to raise your testosterone to levels you enjoyed 5, 10, even 20 years ago or more!”

What it offers

While the primary objective of Prime Male is to restore normal testosterone levels, it also claims to provide 12 secondary benefits. These include:

  • Increased energy levels;
  • More strength by building lean muscle;
  • Helping with your weight loss efforts;
  • Stronger and denser bones;
  • Elevated overall mood and confidence;
  • Enhanced libido and sexual performance;
  • Lower blood pressure;
  • Improved cardiovascular health;
  • Better control over your blood sugar levels;
  • Optimal prostate health;
  • Tighter and overall healthier skin;
  • Enhanced cognitive functions such as memory and focus.

How it works

Prime Male enlists the help of 12 distinct ingredients, each with a clear & scientifically-backed reason for being included in Prime Male’s formula. 

For instance, it includes D-Aspartic acid (DAA) as the primary testosterone-boosting substance due to its correlation with testosterone-producing luteinizing hormones. Simultaneously, components like Boron, Magnesium, and Nettle root block Sex Hormone-Binding Globulin (SHBG); a protein that lowers free testosterone concentration.


  • Formulated specifically for men age 30 and older;
  • Offers quick and long-lasting testosterone boost;
  • Vegan-friendly with vegetable cellulose capsules;
  • Acts as an anti-aging supplement for older men;
  • Claims to have zero recurring side effects.


  • Requires you to take a capsule four times every day.

What is TestoFuel?

TestoFuel asks the question, “Struggling to pack on the muscle?” and then offers a thorough solution with their testosterone-boosting supplements. In their own words, TestoFuel is designed to naturally boost your T levels and provide the following benefits:

  • Accelerated muscle growth;
  • Increased muscle strength to allow more intense workouts;
  • Reduced excess body fat;
  • Improved mood and motivation;
  • Boosted self-esteem and confidence.

One thing that’s clear from these claims is that TestoFuel has a rather strong focus on male fitness. Its primary goal appears to be helping you achieve your ideal body shape in as little time as possible by utilizing the natural muscle-building properties of testosterone.


TestoFuel contributes most of its benefits to three key ingredients, D-Aspartic acid, Vitamin D, and Oyster extract. 

Among these, DAA and Vitamin D are included for their positive impact on testosterone levels, and — consequently — your muscle growth. Oyster extract, on the other hand, is used as a natural aphrodisiac for revitalizing your libido/sex drive and improving your mood.


  • Increases testosterone levels quickly;
  • Clear focus on helping you build strong, bulky muscles;
  • Just as suitable for women as it is for men;
  • Offers faster post-workout recovery;
  • Improves energy levels and reduces fatigue.


  • No claims of being vegan or vegetarian-friendly.

Key differences between the two

While Prime Male and TestoFuel offer the same key benefit of returning your testosterone levels back to normal, their overarching goals could not be any different. Here’s how.

You can think of Prime Male as an anti-aging supplement. This is not to say that it’ll magically make you younger. But, it does aim to reverse most symptoms of low T that come with age, like low energy, reduced libido, muscle loss, and weight gain.

On the contrary, TestoFuel is like a safer alternative to muscle growth supplements. It aims to augment your workout efforts by accelerating muscle growth, speeding up the fat-burning process, and reducing the recovery time between workout sessions.

Shared ingredients 

Prime Male and TestoFuel share seven ingredients with each other. These include:

D-Aspartic acid

D-Aspartic acid is one of the fastest testosterone-boosting substances in most testosterone boosters. Studies show that regular consumption of D-Aspartic acid can boost testosterone levels by 42%. What’s even more surprising is that this drastic increase can occur in as little as 12 days of DAA supplementation.


Boron is an active inhibitor of Sex Hormone-Binding Globulin which is a protein that binds itself to free testosterone to decrease its availability. A 2011 study by Reza Naghii et al. shows that these SHBG-blocking properties of Boron can result in a 28% increase in testosterone levels with regular supplementation.

Ginseng extract

Ginseng is a natural aphrodisiac that can offer both short and long-term improvements to your libido and sex drive. It is also used as a potential treatment for sexual disorders like erectile dysfunction and infertility.


The concentration of Magnesium in your body appears to have a direct correlation with T levels. A 2011 study by Cinar et al. shows that Magnesium intake can increase T levels in both sedentary and athletic men. Though, more research is required to understand the underlying physiology of this connection.

Vitamin D

Studies show that dietary Vitamin D intake can increase testosterone levels. More importantly, Vitamin D supplementation is linked with increased upper & lower body strength, as well as faster muscle growth.

Vitamin K2

Vitamin K2 consumption can increase testosterone levels by as much as 70%. This connection was clearly observed in a 2011 study by Ito et al. involving rats and testis-derived tumor cells.


Zinc doesn’t boost testosterone directly. But, its deficiency can lower your T levels by as much as 75%. Thankfully, Zinc supplementation can counteract these symptoms — returning your T levels back to normal.

Prime Male unique ingredients

Prime Male contains five components that are not present in TestoFuel. These are:

Ashwagandha extract

Ashwagandha offers similar aphrodisiac benefits to Ginger extract. It also protects your testes from age-related oxidative damage. This makes Ashwagandha an effective treatment for infertility and allows it to regulate testosterone production in the long run.

Nettle Root extract

Nettle root extract acts as an inhibitor for 5-alpha reductase; an enzyme that converts testosterone into Dihydrotestosterone (DHT). While this conversion is a natural part of men’s physiology, too much 5-alpha-reductase activity can lower serum T levels.

Vitamin B6

Animal studies show that Vitamin B6 deficiency can lead to a drastic and rapid decrease in serum testosterone concentration. Fortunately, B6 supplements can reverse these symptoms and prevent them from returning.

Black pepper

Black pepper doesn’t offer any direct benefits for your testosterone levels. But, it does contain Piperine which can increase the bioavailability and effectiveness of other testosterone-boosting ingredients by 30-200%.


Luteolin helps regulate androgen (testosterone) production by the Leydig cells in your testes. Studies show that Luteolin intake might be good for your cardiovascular health as well. 

TestoFuel unique ingredients list 

Out of its ten ingredients, only three are unique to TestoFuel. The two you should know about are:

Fenugreek extract

Fenugreek extract is a well-known testosterone-boosting substance that can increase T levels by 46%. Its benefits are similar to D-Aspartic acid. But — unlike DAA, which shows results in 12 days — Fenugreek offers a long-term T level increase after 12 weeks of use.


Maca is a performance-enhancer that can provide a noticeable increase in aerobic performance after just two weeks of use. It is also associated with increased sex drive in most users.

Side effects

Both Prime Male and TestoFuel report zero side effects. Even if this claim is true, it does not make these supplements 100% safe for everyone. At the end of the day, these are over-the-counter supplements that you can get without a prescription. 

So, make sure to do your research, read their list of ingredients for possible allergens, and maybe even consult your doctor before making a purchase.


So, which of the two is better for you, Prime Male or TestoFuel? The answer to this depends on what you’re looking for. 

Prime Male is the way to go if you want a T-boosting supplement that will make you feel young again. But, if you’re after shredded muscles that are both bulky and strong, TestoFuel is the muscle growth supplement better suited for you.
