What’s The Difference Between Testofuel and Prime Male

Note:This is just a review. Click Here to visit the official Prime Male website.

Any guy in his mid-to-late 40’s or early 50’s knows the symptoms…decreased energy, lack of libido, poor sleep quality. They can all be attributed to a lack of testosterone production, which starts its 1% per year decline right around the age of 30. Sure there are prescription remedies for the problem, but they often are simply a “band aid” type fix for an otherwise annoying problem.

Quick Tip: Are you under the age of 40? Then check out a supplement called Testofuel.

testofuel review

It’s specifically geared towards men aged 40 and under, and will give you MUCH better results than Prime Male.

Recently, there has been a surge of so called “testosterone boosting supplements” that have been introduced to the supplement market, and many of these products claim to help fight this decline in testosterone and help you live a better life. One such supplement we recently got a chance to review is called Prime Male, which was just released not too long ago.

But what makes this supplement so special, and more importantly, does it really work? Read more in our detailed and comprehensive review to learn more.

What is Prime Male?

Made up entirely of all natural ingredients, Prime Male promises to deliver a host of benefits including enhanced energy and libido, gains in lean muscle, and an overall improvement in performance.

While it contains many of the same ingredients in Testofuel, Prime Male adds a number of all natural extracts that Testofuel doesn’t have. The complete ingredient list includes:

Mucuna Pruriens has actually been studied for its effects on helping men with Parkinsons disease, but has also been shown effective at helping anxiety.

Because Nettle Root Extract contains 3,4-divanillyltetrahydrofuran, bodybuilders have been using it to help boost free testosterone levels by occupying the sex hormone binding globulin. (1) The final ingredient, Bioperine, has been studied for it’s properties at allowing the nutrients and vitamins in Prime Male.

The nice thing about Prime Male is that it doesn’t contain any harmful stimulants like Yohimbe, so you wont see a drastic increase in energy, followed by a huge crash later in the day.

So How Does Prime Male Work?

The primary ingredient, D-Aspartic Acid (DAA), as well as the addition of 100 mg of Magnesium and Luteolin is what truly gives you the most benefit here. DAA is a NON-essential amino acid that is generally made by our own bodies if we consume enough ESSENTIAL amino acids. In a clinical study conducted on mammals at the University of Naples, there was evidence that DAA reacts within the brain to release luteinizing hormone, or LH. LH passes through the testicles and enters the Leydig cells, which is exactly where testosterone is produced.

That’s a really cool story, right? But, what about in humans? Well, research has shown that by taking DAA for a period of 12 days can increase your free testosterone levels by as much as 40%. (2) Couple this with Magnesium (which helps to lower your sex hormone binding globulin count) and Luteolin (which inhibits the action of Aromatase, reducing the production of estrogen), and you have yourself a winning combination.

How Do I Take It?

According to the label, Prime Male is designed to be taken as part of a daily supplement regiment. The directions state that you should take 1 capsule, 4 times per day with food.

My Personal Results

As noted in the video review above, I actually didn’t get a chance to take Prime Male out.

My testosterone levels are already higher then normal for a guy my age (34), so I didn’t think it would be a good “test” if I tried it out.

prime male testosterone reviewHOWEVER, I did have a friend of mine named John, who’s 43, try it out and this is what he had to say in summary:

“I’m a 43 year old male who’s been suffering from low testosterone since I was in my mid 30’s.

I felt like I couldn’t perform as well in the sack with my wife, and have definitely noticed my energy levels are not what they once were.

I started taking Prime Male and can say that I started feeling the effects almost immediately.

The first thing I noticed was that I was waking up with a morning wood, almost every morning,

Also, and I’m not sure if this was a result of the supplement or what, but I noticed my energy levels were picking up big time. I didn’t feel as tired all the time, and seemed to have more energy / motivation to hit the gym.

The only side effect I noticed was that I had a little bit of stomach discomfort (likely from the magnesium in Prime Male), but it wasn’t anything to the point where I felt like I had to stop taking it.

Thanks for letting me try this out, I highly recommend it to any guy my age looking to improve his performance, energy, and libido.”

What’s The Difference Between Testofuel and Prime Male?

prime male vs testofuel

TestoFuelcontains a higher dose of DAA (2300mg), making it a more potent muscle builder and ideal for younger guys in their20’s and early 30’s that are already enjoying peak T levelsbut want to take their T levelseven higher& muscle buildingresults evenfurther, with the stimulation that a high dose ofDAA provides.

As you are probably already aware, testosteronelevels peakin the late teens to early twenties, and decline slowly thereafter.

Prime Malecontains less DAA (1800mg) but contains three additional ingredients; Mucuna Pruriens, Nettle Root Extract & BioPerine.

These additions are all designed to benefitthe slightly older guy(40+) whose T levels are naturally on the decline.

Here’s how:

Mucuna Pruriens has been shown to reduce Prolactin levels in guys, which naturally rise with age,aiding thedecline in T.

Mucuna is also a potent T booster on its own, with studies showing around a 20% increase in T levels for guys with lower levels to start.

Nettle Root Extract has been shown in studies to bind with SHBG, freeing up more testosterone in the system.

SHBGincreases more and more with age, starting around the same time T starts declining.

BioPerine is a natural bioavailability enhancer.

It helps boost the absorption of PM’s T-boosting nutrients.

Again, nutrient absorption declines with age, which is why healthcare professionals recommend higher doses ofsupplements to adults thanthey do tokids & teens, for example.

In summary: The additional ingredients in Prime Male are unnecessary in Testofuel.

And vice-versa.

What About Prime Male Vs. Testosterone Max

Testosterone Max uses a completely different, albeit very effective, formula then Prime Male. Instead of using D-Aspartic Acid, Zinc, or Oyster extract, Testosterone Max uses DHEA, a powerful hormone that acts as a precursor to the development of testosterone.

DHEA is actually produced naturally in the male adrenal glands. However, just like testosterone, it has a tendency to peak in your mid-20’s and start a gradual decline as you get older.

This is where Testosterone Max thrives…

By supplementing with Testosterone Max, your body should (in theory and in practice) start to increase your bodies own natural testosterone production.

It also uses other powerful ingredients such as L-Carnitine, Vitamin E, and Tribulus Terrestris to amplify the effects. Other benefits include increased energy levels, weight loss, and improved sex drive.

I’ve personally used Testosterone Max with some VERY good results. Click Here to read more in my official review.

Where Can I Buy It?

At the time of this review, the Prime Male testosterone booster is only available on their official website, A one month supply will run you $69, but if you order a 3 month supply they give you a free box, plus free shipping. Since the supplement is backed by a 90 day money back guarantee, there is no risk to ordering a larger quantity. I actually recommend that you order at least a 2 months supply, as it generally takes a couple of months to see the best results anyway.

Will It Flag A Drug Test?

prime male smallI get this question alot, so I figured I’d include it here. I have thoroughly researched ALL of the ingredients in Prime Male and cross checked them with my resources at the NCAA and FDA, and NONE of them are on the banned list. That said, many will ask if they will trigger a false positive on a drug test.

There is always a small chance that too much of any ingredient may flag a blood test, so I recommend that if you are routinely tested or that worried about it that you bring the bottle to the testing agencies office with you and explain that you’ve been taking it.

But I would say with 99% certainty that you will NOT be flagged for a false positive on a drug test.


If you’re a guy in his 40’s, 50’s, or even 60’s and you’re looking for something to help not only get your libido back, but also increase energy, strength, and endurance, Prime Male just might be the supplement for you. While it is a bit on the expensive side, my research has shown that this testosterone boosting supplement has all of the necessary ingredients to help you get your mojo back.

I am 42 years old and have been working out for a year now and have made some great gains. I have been considering a testosterone booster to further these gains. My testosterone levels are good but I find that I'm low on energy. I question how you can give a review on Prime Male without using it? I'm conflicted ongoing with Testofuel or Prime Male. -Rob

I've used Testofuel personally, and I've gotten great results.  And I'm not a guy with low testosterone levels. Because of that, I had someone else test Prime Male for me. He felt the libido boost, the muscle growth, and the energy.  I think you'd do best with Testofuel.- Rob
