TestoFuel vs Prime Male Testosterone Booster Comparison

It’s Goliath Vs Goliath as we bring two of the best testosterone booster supplements together in our TestoFuel vs Prime Male review for a true battle between the outstanding names on the market.

These great supplements won’t leave you disappointed, but just how do they compare? They both have bold claims they can back up including:

  • They will significantly raise testosterone levels
  • Increase your libido
  • Enhance your mood
  • Help you get an increase in muscle and strength
  • Give you more confidence

These claims are big, and as always, we believe it all comes down to the ingredients. You might expect the ingredients list to be as impressive as they come, so let’s see just how well they compare to one another.

Who makes these Testosterone Boosters?

Roar Ambition

These guys are the company behind TestoFuel and we should tell you straight off that they have a real good reputation online, not just for their products, but also their customer service.

They have a generous 90-day money back guarantee which is one of the best we have seen. Roar Ambition also review and amend their ingredients and dosages regularly, ensuring the customer is getting a great product.

They are the people behind some other great supplements including the popular fat burner Instant Knockout (check out our review here).

A man who knows a thing or two about testosterone is former Mr. Olympia Robby Robinson, who in his 70’s still looks incredible and still vouches for TestoFuel.


Prime Male Testosterone Booster Review

Check out our Prime Male review

Their brain child is Prime Male and their great reputation is built around this product. Slightly different from TestoFuel in that it is marketed towards men over 30 – clever in that this is when your testosterone levels start to decline and continue to do so for the rest of your life.

They don’t have any other products at this moment in time, but even if they did, that’s not what we are here to talk about anyway.

TestoFuel vs Prime Male Ingredients

Like we said earlier, this is the important stuff and what every good supplement should be critiqued upon.

If it’s natural then that’s always a good start and with the right dosages and ingredients, any supplement has a chance of being a success.

You should check the nutrients before you consume anything as the supplement world can be a minefield. This way you give yourself the best chance of avoiding any unwanted side effects.


The dosages of Vitamin D3 deserve credit for both TestoFuel as well as Prime Male. It is such a significant part of any testosterone booster that getting it right is essential.

Because it is a great overall ingredient, it works wonders for your testosterone levels as well as working against fatigue, but the best possible dosage you can get for optimum results is around 5,000 IU a day.

Both of the products reviewed here contain the exact amount required for best results. One of the things we have noticed in our TestoFuel vs Prime Male article so far, is that the dosages are great.

Prime Male vs TestoFuel review

D-Aspartic Acid

The most effective dosage of this is around 2,000-3,000 mg depending on where you get your information, this seems to be what the experts believe.

TestoFuel contains 2,300 mg of D-Aspartic Acid meaning they have included an optimal amount.

Prime Male falls just short with a dosage of around 1,600 mg, although it will do a good job, it won’t be as effective.

Asian Red Panax Ginseng

Another great ingredient for multiple purposes including raising your testosterone for both general and sexual health, elevate your mood as well as your immune system.

The high dosage amounts fall well within the recommended amount for best results and there isn’t much to separate them in terms of dosages.

Prime Male Ingredients

This is where we see just how they differ and can really tell them apart. The larger the amount of effective ingredients the better, as long as the dosages are good.

Prime Male’s Best Ingredients:

  • Boron
  • Nettle Root
  • Mucuna Pruriens

All of these are well known testosterone boosters with other benefits as well. They are considered to be high quality and not filler ingredients and because they are natural, there are no side effects to worry about – always important to us!

Some studies will dispute the effectiveness of Nettle Root as a testosterone booster but it does have other health benefits anyway such as aiding joint pain, hay fever as well as supporting a healthy prostate.

TestoFuel’s Best Ingredients

  • Oyster Extract
  • Zinc
  • Fenugreek

Another 3 ingredients that all have health benefits, all 3 of these have been shown to support an increase in testosterone levels. Fenugreek is one of the better ingredients you will find in a T booster as it is great for your libido as well which is what many people will use a testosterone booster for.

It is well known that in Western culture, men do not consume enough Zinc as part of their diet. This is bad news as it is great for your body in many ways such as your appetite for sex, immune system and much more. Supplementing it therefore, is very important.

The Oyster Extract is also very effective but also take note if you have any allergies to this ingredient.

TestoFuel vs Prime Male Endorsements

A big pull towards TestoFuel for the masses is the fact that Robby Robinson uses it. The former Mr.Olympia is still looking great in his 70’s now and is considered a legend of the bodybuilding world.

He accredits Testofuel for much of his success and even provides a testimonial on their website so he is clearly very happy with the results.

Prime Male also boast of celebrity endorsements and none other than Dolph Lundgren – famous for his role in Rocky IV especially but also many other Hollywood films.

He accredits Prime Male as his source of sexual enhancer so they are clearly working for his testosterone levels.

TestoFuel vs Prime Male Side Effects

Probably why they are such a safe bet and trusted by many happy customers alike – they are safe. Unless you have any allergies, there is nothing in these testosterone boosters that shouldn’t be there.

Everything contained in each bottle is 100% natural and there are no proprietary blends in either, This means you know there are safe amounts of each ingredient and can vouch for the quality of dosages.

It is difficult to separate them, they are both highly regarded for a reason – they are two of the best available. Both are safe to use, have no side effects and can be used in competition.

They are both backed by science and many studies to prove the worth of the ingredients with no proprietary blends in sight.

The feeling for us is that TestoFuel is the better supplement for raising T levels for use in the gym, their dosages are all right up to the high standards of what makes each ingredient the most effective it can be.

Prime Male is good for libido and is marketed in such a way. Depending on your purpose you can try either one with great success.

If we had to lean towards one it would be TestoFuel. This is why it is our most highly rated testosterone booster, it has slightly higher dosages of some of the key ingredients, but also their selection of ingredients appeals to us more.

If celebrity endorsements were anything to go by, you’d need to choose from My Olympia vs Ivan Drago, either way you’re onto a winner.

The main thing is both are proven to do one thing more than anything else – raise your testosterone levels. The fact that they do it safely is a bonus. 

So many people have great things to say about it, including us. To find out more about this excellent testosterone booster, check out our in-depth TestoFuel review.

  • Thank you for this amazing comparison, Oliver!
    I’ve actually tried both, and found Prime Male a little better in comparison, due to the additional ingredients. It’s also because I did not specifically use it for muscle building, but overall testosterone boosting.
    I did a similar comparison on my website, it’d be great if you could check it out and let me know how it looks…

    • Thanks Rohan, pleased you liked our comparison. We really like your site, but unfortunately, we don’t allow links in the comments, but appreciate your thorough comparison and a good contribution to the discussion. As we say above, both are still some of the best t-boosters on the market, even after years of competitor products trying to copy them, but it all depends on your age and aim. We think TestoFuel is a clear winner for the average gym-goer, but Prime Male, as the name suggests, is better suited to the older man who needs a bit of extra vitality!
