Prime Male vs. Testofuel

As we get older, our bodies are constantly changing — it’s something we can’t run away from or avoid. Sometimes it changes in good ways, sometimes it changes in bad ways. Testosterone levels are a perfect example of this because we experience a little bit of both — good and bad. 

For example, testosterone levels start to peak as we hit puberty. It’s what contributes to our voice change, helps our shoulders broaden, results in our reproductive organs maturing, introduces us to facial and pubic hair, and even allows our muscles and bones to grow.

Unfortunately, testosterone levels start declining by the time we hit the age of 30. This can welcome a world of symptoms, including low libido, erectile dysfunction, sleeping pattern changes, lack of motivation and confidence, difficulty concentration, and even depression. 

The good news is you can combat low levels of testosterone with the help of supplements. They help to give your body the nutrients it needs to safely and effectively produce and release testosterone. Two such supplements include TestoFuel and Prime Male, but which is the better choice? That’s what we’re here to determine! So, let’s take a more thorough look at each of these t-boosters. We’ll dive into their ingredients, benefits, and more to decide who the winner is in this comparison of Prime Male Vs. TestoFuel!

Testosterone Boosting For Men

Prime Male vs. TetsoFuel: About the Supplements

The market for testosterone-boosting supplements has grown substantially in recent years as more companies welcome research-backed formulas designed to increase testosterone levels in the body. The industry for this is expected to keep growing as we continue to learn more.

With that said, Prime Male and TestoFuel are two formulas you’ve likely come across on your search for a testosterone-boosting supplement. They’re not only two of the most popular, but they come with some heavy recommendations and extremely positive reviews worldwide. 

Below, we’re going to detail a little bit more about each supplement and the company behind them.  

What is Prime Male?

Prime Male is a testosterone supplement brought to you by ROAR Ambition, the same supplement brand that brings you Hunter Burn, Instant Knockout, Hourglass Fit, Hunter Test, and Hunter Focus. They were founded by Robert Parker in 2012 and are based in Leeds, UK.

Prime Male Supplement by Roar Ambition

The Prime Male formula is designed to increase testosterone levels by releasing luteinizing hormone, decreasing levels of sex hormone binding globulin, and lowering levels of estrogen and prolactin. These are three of the most proven pathways to increasing testosterone levels.

The safe and effective formula contains 12 research-backed ingredients — including D-Aspartic Acid Calcium Chelate, Black Pepper, Boron, Korean Red Ginseng Extract, Luteolin, Nettle Root Extract, Magnesium, Ashwagandha Extract, Vitamin B6, Vitamin D3, Vitamin K2, and Zinc. 

What is TestoFuel?

Believe it or not, TestoFuel is another testosterone-boosting supplement that’s brought to you by ROAR Ambition, the same company that manufactures Prime Male. You might think it’s weird to have two formulas designed to do the same thing, but they do have slight differences.

The good news is ROAR Ambition is dedicated to producing high-quality formulas that use natural ingredients. All ROAR Ambition supplements are manufactured in GMP-Certified and FDA-Approved facilities. They also have facilities in both the United States and United Kingdom.

The TestoFuel formula contains a total of nine research-backed ingredients — including Vitamin K2, Vitamin D3, Vitamin B6, Zinc, Magnesium, D-Aspartic Acid, Asian Red Panax Ginseng, Fenugreek Seed, and Oyster Extract. It’s a little different, but also has several similarities. 

Comparison: Prime Male vs. TestoFuel

Prime Male and TestoFuel are two supplements that claim to do the same thing — improve the natural testosterone production process by giving your body the nutrients it needs to function properly. Not only that, but the two formulas are manufactured by the same exact company. 

Although they share a lot of the same ingredients, there are several striking differences between the two formulas. Understanding these differences — as well as the similarities — is extremely important when trying to decide which supplement is the right supplement for your body. 

Don’t worry, we’re going to detail everything you need to know about both supplements below — including the formulas, benefits, customer feedback, value, and any other considerations we deem worthy. Without further ado, let’s get started!

Prime Male vs. TestoFuel: Supplement Formulation

Prime Male vs. TestoFuel: Customer Feedback & Reviews

Buying a supplement is no different than buying any other product on the market today. In order to ensure you’re purchasing the right supplement, you need to take a look at the feedback from verified customers and testimonials from those that have already tried the formula in question. 

There are a lot of ways you can do this, especially in the modern world today. Social media, blogs, websites, YouTube, and word of mouth are all quality ways to get a feel for how others feel about the supplement. Don’t worry, we’re going to give you a rundown of that below!

Prime Male Customer Reviews

Prime Male doesn’t have a lot of reviews and testimonials on Amazon, but they do feature quite a few on their official website. The one and only Amazon review rated it 3.0/5.0 stars, but there wasn’t any comment as to why — meaning the review holds no weight, which is a bummer. 

Prime Male Customers Review

The good news is Prime Male is sponsored and recommended by Dolph Lundgren, an action movie star and Hollywood legend. As a former chemical engineer and martial artist, his recommendation holds a lot of weight in the male community. Prime Male helped him train harder, maintain energy, improve mood, and recover faster. 

TestoFuel Customer Reviews

TestoFuel has a little more recognition on Amazon, but still not enough to garner a quality understanding of the supplement. With 19 ratings, it holds a 4.1/5.0 star rating. Of those 19 ratings, 71% of them were rated 5.0 stars, 12% were rated 3.0 stars, and 17% were 1.0 stars. 

Testofuel Customers Review

The good news is TestoFuel is sponsored and recommended by Robby Robinson, one of the most well-known bodybuilders today. He’s a 2x Mr. America, 2x Mr. World, 2x Mr. International, 4x Mr. Universe, and 5x Mr. Olympia winner, so his recommendation carries a lot of weight. 

Prime Male vs. TestoFuel: Other Considerations

Aside from the background information about the company, the formulas, benefits, and customer feedback, there are plenty of other considerations you need to account for when making the right decision for you and your body. There’s a lot that goes into this decision.

Since there are a few things about each supplement that we haven’t mentioned yet, we’re going to take the time to list those things out. Some of these considerations below might be the deciding factor for you, which is why we don’t want to leave you hanging — you’re welcome!

Prime Male vs. TestoFuel: Supplement Value

By now, we’ve gone over just about everything you need to know about TestoFuel and Prime Male — everything except the price tag behind the supplement. Of course, that’s going to play a major role in which one you decide to go with. Don’t worry, we’ve got you covered, once again!

TestoFuel costs you $59 per 1-month supply, but you save money by bundling. A 3-month supply costs you $118 with free shipping in the US and UK, a 5-month supply costs you $177 with free worldwide shipping, and a 12-month supply costs $495 with free worldwide shipping. 

Prime Male costs you $69 per 1-month supply, but you can save money by bundling. A 2-month supply costs $138 with free shipping in the US and UK and a 4-month supply costs $207 with free worldwide shipping. You can also combine it with Prime Male Enhance (Virility Support).

Prime Male vs. TestoFuel: Which Supplement Is Better?

It all comes down to this — which supplement is the better option for you, TestoFuel or Prime Male? It’s a difficult decision considering how similar the two are, but we believe there’s a clear winner after looking at the supplement formulation and overall value they offer customers. 

The clear winner has to be Prime Male and a big reason why is the inclusion of Black Pepper Extract and Ashwagandha. These two ingredients really set Prime Male apart from TestoFuel. You also have to take into consideration that Prime Male offers larger dosages where it counts.

That’s not to say that TestoFuel is a bad formula, but we certainly believe Prime Male is the better of the two — which makes sense that it costs more. The good news is it’s only a $10 difference and you can save money by bundling, making it less of a blow to your wallet. 

If you’re looking for something with even higher dosages, especially when it comes to D-Aspartic Acid, don’t hesitate to look at another testosterone-booster manufactured by ROAR Ambition — Hunter Test. It’s a little more expensive, but it’s 100% worth it in our eyes!
