prime male reviews

There are a lot of supplements out there that claim to boost your testosterone. They advertise all over television, using visual metaphors like clogged garden hoses, and all over the radio. It’s hard to cut through the noise and find out what actually works.

Prime Male has a unique blend of natural ingredients – but that’s what all the other brands claim, too. Prime Male is clinically proven – but so are most of the others you hear advertised. What makes it different, if anything?

To help you make this difficult decision, our team has compiled a variety of positive and negative Prime Male reviews. We’ve distilled the information as simply as possible, so you can learn everything you need to choose the best supplement for you and your body.

What Is Prime Male?

Prime Male is a supplement for boosting testosterone, especially in aging men. It’s a subsidiary of Roar Ambition, a U.S.-based company that specializes in organic supplements for men. 

Prime Male’s formula includes twelve different compounds which work together to help your body burn fat. Some of the ingredients are fairly common, such as magnesium and Vitamin D3. Others, like nettle extract, boron, and D-Aspartic Acid, are more rare to find in health supplements. 

All of these ingredients are backed by science, not just individually but also together. Prime Male states that this combination of twelve active ingredients has been shown to be the most effective. It is worth noting, however, that they don’t cite any studies supporting this finding.

How Does Prime Male Work?

Prime Male works through a variety of methods. Of course, it contains many natural ingredients that are proven to increase testosterone directly, but some of its ingredients are tailored to other effects as well.

Some scientists claim the effects of testosterone can be slowed by certain lifestyle changes. These include managing stress, increasing activity, and getting better sleep and nutrition. Many of the ingredients of Prime Male are targeted toward these effects. You can find a list of each ingredient and what it does here[1]

Low testosterone can be caused by defects in your body’s production or defects in hormones that stimulate production. A major cause of low testosterone[2] is a lack of the luteinizing hormone, which signals your body to manufacture testosterone. Prime Male signals the body to increase testosterone production by mimicking the hormones that cause it.

Prime Male Ingredients

D-Aspartic Acid Calcium Chelate (D-AA-CC)

D-Aspartic Acid Calcium Chelate is the wonder ingredient of Prime Male. It’s been shown to improve testosterone[3] and turn back the clock on aging. The Prime Male website describes a study in which testosterone improved by over 42%.

Prime Male Ingredients

The website is actually inaccurate here: it says that since testosterone usually drops by 1% each year, this is like turning the clock back by 42 years. That’s not actually how percentages work. For example: If you take 50% off of the number 100, you subtract 50, and 50 remains, but if you add 50% back, you only add 25, for a total of 75. 

Similarly, if you have 58% of your testosterone remaining (after 42 years of 1% decline), and you add 42% of that amount, you only get 82% of your original total- or 24 years regained. That’s not even considering the fact that those 1% losses will compound on each other instead of taking 1% of your original total each time.

Black Pepper

The interesting thing about pepper is that it helps your body absorb nutrients – any nutrients. It’s commonly included in many supplements because it increases the bioavailability of every other compound in the supplement. It supports the absorption of every other ingredient in Prime Male.


Boron seems to improve testosterone levels. It also supports blood plasma, improves Vitamin D creation, and reduces inflammation. Despite all this, it’s fairly rare in food, so supplements are a good way to get some.

Ginseng Extract

Ginseng is great for your immune system, so it’s frequently found in all sorts of other supplements. It’s also traditionally used to treat impotence and ED, going back thousands of years. It seems to work fairly reliably.

Alternatives To Prime Male

There are plenty of other testosterone boosters out there. Some are similar, and some are very different. Nothing else has the exact same proprietary blend of ingredients as Prime Male, but TestoFuel is actually made by the same company, Roar Ambition. Here are a few competitors and their pros and cons.

Health Benefits Of Prime Male

There are a lot of potential benefits to taking Prime Male. Each of the twelve ingredients contributes something different! Here’s just a shortened list. 

Obviously, it can increase your body’s testosterone production. It also reduces the amount of sex hormone-binding globulin (SHBG), which can bind to testosterone and prevent it from being used. The added testosterone has additional health benefits and can reduce or reverse some other forms of aging[4]

On top of that, Prime Male also blocks the creation of estrogen and other female hormones, which the male body still produces to some extent. A hormone called androgen can transform in the body into either testosterone or estrogen[5].

Other ingredients help to increase energy and bolster the immune system. Prime Male can lower stress and blood sugar levels, too, and it can improve your mood. It has definitely been formulated to combine all the best possible effects.

Potential Side Effects

Prime Male has few side effects, and they’re rare. Some reviewers reported diarrhea. The ashwagandha can also cause sleepiness (especially if you’re already taking a sedative to help you sleep), and the amino acids can intensify kidney problems.

The most significant danger of Prime Male is that it has some blood thinning effects. This is caused by piperine, a compound taken from black pepper. Usually, blood thinners are very helpful; they reduce high blood pressure and help avoid blood clots.

You need to be aware of piperine’s blood thinning properties because it prevents you from taking Prime Male alongside other blood thinners. Medicines are very carefully formulated not to thin your blood too far, or else your blood might not clot on minor cuts, leaving you bleeding continuously. You also can’t take any blood thinners at all within two weeks of surgery, including Prime Male. Again, this is to avoid bleeding uncontrollably. 

How To Take Prime Male?

Prime Male testosterone booster comes in easy-to-take pill capsules, and you’re meant to take four a day after meals. That’s one after breakfast, one after lunch, one after dinner, and then another somewhere throughout the day.

That can be helpful if you eat more than three meals. If you eat three, try taking the fourth in the mid-afternoon. If you’re intermittent fasting and you eat fewer than three meals, Prime Male may not be the ideal supplement for you.

Prime Male Review: What Do Real Users Say?

The website has a lot of testimonials[6], but there’s no unbiased source for large numbers of reviews. Prime Male is not available on Amazon or other similar sites, so the only visible reviews are the ones Prime Male’s staff has selected to display on their website. This makes it unlikely for you to see any negative reviews at all.

Prime Male Reviews: How it Works, Benefits & Precautions

Prime Male has research-backed ingredients that work together to do more for your body. It boosts testosterone, helps you get fit, and uplifts your energy and mood. 

  • Offers many features – it seems to do everything!
  • Natural product
  • FDA-approved manufacturing facility
  • Minimal side effects reported
  • No hidden ingredients or proprietary formulas
  • Global shipping
  • No money-back guarantee or returns of opened product
  • Fairly expensive
  • Requires four doses a day

Prime Male is an intense supplement, but it’s also safe. The side effects are few and rare, and every ingredient is carefully monitored. The team behind the company keeps an eye on studies to ensure everything remains safe.

The product is all-natural and manufactured in an FDA approved facility. It does require four pills per day, so one 120-capsule bottle is only a one-month supply. You can bundle several bottles for a better price, and the product ships free to the US and the UK. 

The best characteristic of Prime Male is its multitude of functions. It’s able to boost testosterone levels[7], of course, but it also increases energy, contains vitamins and minerals, and even assists the immune system.


Because Prime Male has a variety of different ingredients, more than most testosterone supplements, it’s hard to explain the dosage. For example, a day’s dose (four pills) contains 1600 milligrams (mg) of D-Aspartic Acid, which is the most essential ingredient. But it also contains 45 micrograms of vitamin K, 30 mg of zinc, and five mg of boron.

Where To Buy Prime Male

Prime Male is currently mostly available on their own website. The parent company, Roar Ambition, has a handful of brick-and-mortar stores as well. 

Prime Male is not available on Amazon. There is a product on Amazon called “Prime Male,” but it’s actually a different product capitalizing on brand confusion. The best way to spot the difference is to look for a stylized lion crest, which is the logo of the real Prime Male.

What Does Prime Male Cost?

On its website, Prime Male currently costs $75 for one bottle, which is a month’s supply. A two-month pack is $150 but includes free workout and diet guides. A four-month supply is only $225, equivalent to the cost of three bottles instead of four, and still includes workout and diet plans.

Final Thought

Prime Male is a reliable, safe, effective testosterone-building supplement. It’s very expensive, but it’s been well-studied and you can be confident you’re getting what you pay for.

Frequently Asked Questions

Who should use Prime Male?

Men over the age of 30 can use Prime Male to help avoid the effects of decreasing testosterone, which starts around that age. Women may be able to use Prime Male, but should definitely not take it while nursing or pregnant.

What are the risks of Prime Male?

Prime Male has some side effects, including diarrhea, sleepiness, and kidney problems. It should not be used with a blood thinner or within two weeks of surgery. The risks are minimal, though.

What is the difference between testosterone and free testosterone?

Free testosterone is not bound by sex hormone-binding globulin or SHBG. The total amount of testosterone in your body might be less than the amount available for you to use. 

How do I know if I have low testosterone?

Consider asking your healthcare provider for a test to measure your blood serum testosterone levels. This will let you see if age is beginning to take its toll.
