The Majority of our clients fall into the general weight loss and lean muscle growth categories. And we do a lot of work with them to come up with a supportive diet and supplement stack.

One of the products we advise for all men is a testosterone booster, which often raises some eyebrows.

We’re not talking about dodgy steroids or illegal drugs.

There are completely natural products like Prime Male that may help a lot of men with low testosterone problems.

So, our fitness experts picked 8 of our clients to run a trial and find out how well Prime Male works.

Let’s start with the basics.

What Is Prime Male?

Prime Male is a testosterone booster based on a formula of natural herbs, vitamins, and minerals.

The company refers to its formula as the A-team or anti-aging dirty dozen.

Yes, that’s the cheesy 80s TV show with Mr. T.

Anyway, they can call it whatever they want as long as the ingredients do what they claim to do.

And we’ll get to those details in the next section.

What Roar Ambition Ltd. claims is that every single ingredient has been chosen because of scientific proof that it may increase testosterone levels.


The company also claims that customers could expect improvements in these key areas:

  • Increased muscle mass
  • Improved sex drive
  • Burn away some belly fat
  • Reduce fatigue levels
  • Balanced mood
  • Better concentration

During our testing phase, we made sure that our clients kept a journal on these topics so that we could come to a conclusion on those claims.

And we’ll get to the results after we look at the ingredients.


Prime Male Ingredients


The first thing we did is have a nutritionist look at the 12 ingredients on the label and provide us with some feedback.

We also looked for studies to back up the claims and see how this formula might boost testosterone levels.

One thing to point out is that we liked that the label is completely transparent, which made our research a lot easier.

1 - D-Aspartic Acid Calcium Chelate

D-Aspartic Acid Calcium Chelate

I had heard of D-aspartic acid calcium chelate but was a bit intimidated by the sound of it.

Apparently, you could call it DAACC, and nutritionists would know what you’re talking about.

This is a common ingredient in testosterone boosters, including a famous brand called TestoFuel.

Some studies have tied it to body functions that stimulate the testes to produce more sex hormone.

2 - BioPerine

This is an extract from black peppercorns, and several studies have concluded that it may help your digestive system to absorb more nutrients [1]. It’s included in Prime Male as it may help to make it more effective.

3 - Boron


One interesting study we saw linked this mineral to a decrease in sex hormone-binding globulin (SHBG), which may lower the level of free testosterone [2].

This should technically increase testosterone levels floating around your body.

It’s not surprising that many known t-booster brands also have this as their primary testosterone boosting ingredient.

Those trials also used doses that were ten times stronger than what Six Star is providing, so we’re a bit skeptical about it.

It seems to be included because it’s so common in the herbal community. But we generally prefer seeing some scientific evidence as well.

Let us also just list out the non-active ingredients that make up the pills:

  1. Microcrystalline Cellulose
  2. Dicalcium Phosphate
  3. Stearic Acid
  4. Croscarmellose Sodium Coating
  5. Crospovidone
  6. Silicon Dioxide
  7. Magnesium Stearate

Thehave no real impact on your body and are just part of the binding material to deliver the active ingredients into your stomach.

4 - Korean Red Ginseng

Red ginseng is often called the gift from the orient, where it has been used for centuries to improve fertility. But we generally don’t rely on just traditional medicine opinion.

Our nutritionist did point out that a study from 2013 found a positive relationship between this herb and testosterone boosting abilities [3].

“Practitioners of traditional Chinese medicine have used red ginseng to prepare a tonic designed to boost a person’s energy. The ginseng plant contains compounds known as ginsenosides believed to have this beneficial effect on the human body.”


- Rachel Nall, freelance medical writer.

5 - Luteolin


This is an ingredient that is extracted from citrus fruit, and a clinical study has revealed that it may be a powerful inhibitor of estrogen [4].

Yes, even men produce it, and it could stop you from losing weight and getting a more ripped appearance.

Some people would say it makes you a bit soft.

6 - Magnesium

This is an important mineral for all athletes, as it may play a role in your muscles' ability to process energy. It may also help with the recovery process.

But a less known fact is that it might help with processes that allow testosterone production to result in free testosterone that could trigger the right growth responses you’re looking for.

7 - Mucuna Pruriens

Another hormone that men want to avoid is prolactin, which may limit the amount of free testosterone available. This ingredient has been shown to limit the prolactin concentration in your body.

8 - Nettle Root

Nettle Root

Nettle root is something that you might find in health food stores, but the company claims that it may also help with increasing the number of free T cells in your bloodstream.

We did found a few studies that seemed to support this, but some of the results were mixed.

9 - Vitamin B6

Most people may be aware that this vitamin plays a role in the production of red blood cells. But medical science also suggests that it may be an important building block of testosterone production

10 - Vitamin D3

Vitamin D3

Vitamin D3 is often called the sunshine vitamin as our skin produces it when exposed to sunlight.

It plays multiple orioles for your immune system, overall health, and energy levels.

This supplement contains a good dose, so if you’re taking it as a standalone pill, then you could save on one less product.

11 - Vitamin K2

Vitamin K2 has only recently become a more common vitamin to be recommended by nutritionists. Studies suggest that it may help other vitamins function better, but is also tied to increases in T counts.

12 - Zinc

This is one mineral that has possibly been studied more than any other on this list. Countless trials have been conducted, and they have managed to directly tie zinc to testosterone production.

It seems like it’s a mineral that may be directly involved in the chemical structure of T cells.

“Moderate zinc deficiency is associated with hypogonadism or testosterone deficiency.”


- Dr. Mike Bohl, MD.

Pros And Cons

prime male

The first thing our research revealed is that there seem to be a lot of positive comments in forums about this natural testosterone booster. Prime male reviews also tend to say that it’s easy on the stomach, and they liked that it’s not reliant on stimulants.

There’s also a good selection of vitamins that may mean you could save on other supplements.

And if you’re a bit unsure, then keep in mind that Prime Male testosterone booster comes with a money-back guarantee up to 90 days.

  • Many positive reviews about noticeable changes within weeks
  • Contains Vitamin D3 and B6 for general health improvements
  • With 1.6 grams of D-aspartic acid, it may be strong enough to raise natural testosterone levels
  • Avoids the use of stimulants that could make you jittery
  • Comes with a 90-day money-back guarantee
  • You’ll need to set a reminder to take it four times a day

The other negatives were the lack of estrogen blockers. But since it wasn’t overly potent on the T count side, that might not be a real issue.

Also, if you struggle swallowing tablets, then you may need to break these in half as a few people mentioned that they tend to get stuck.

So far, our conclusion wasn’t overly positive.


Our Test Results

Now for the important part.

As mentioned above, we worked with eight clients who were either trying to lose weight or in bulking programs, to see if taking Prime Male might help them with their goals.

Two of our weight management clients weren’t taking any fat burning or pre-workout supplements. We were able to see a slightly faster fat reduction over the 6-week trial.

The other two clients were taking fat burners, but they also noted some positive effects on fatigue and their general mood and concentration levels.

Next, we looked at the bulking results for the other four clients.

None of them had been taking a testosterone boosting product before, which made them good test subjects.

The measured increase in muscle size accumulated faster In all four cases.

That meant they were achieving more from their bulking phases each time.

It’s also important to note that their body fat went down as well, which is often difficult to achieve in a bulking phase.

Those side effects could be the result of sudden fluctuations or too many highs and lows.

In some cases, this could result in some acne outbreaks, especially if you’re susceptible to outbreaks anyway.

But we also found that some people got quite irritable and anxious.

If you ever find such negative effects, then make sure you stop taking the pills immediately and possibly talk to your doctor as well.

Side Effects

side effect

Our nutritionist did some additional research into the Prime Male ingredients to find out if there were risks of side effects.

Her comment was that they are all generally classed as safe, and allergies to them are rare.

Our own clients didn’t report any issues, so we looked at reviews of Prime Male in forums and the official website.

Overall, people don’t seem to have any stomach issues like cramping or bloating.

And it seems that spreading the dose throughout the day may also be helping to avoid a sudden spike.

But you still need to watch out for things like mood swings, as you may be more sensitive to increases in the male sex hormone.

Here's a list of testosterone boosters you can try in case you experience certain side effects:

Where To Buy Prime Male

The only place we would send you to buy Prime Male is the official website.

And there are three main reasons for this.

Firstly, it’s the only way to make sure you avoid a counterfeit product.

Unfortunately, there are many dodgy online retailers where you could end up with a product that does more harm than good.

Secondly, it may be the best place to get great deals. The six month supply option seems to be the most favored with performance athletes.

And finally, you’ll only get the money back guarantee if you buy it from an official source.

Prime Male Reviews

user reviews

So our test results were positive, but we also want to bring you some Prime Male reviews from around the world that we found interesting.

He says that this product changed his life and physical shape. He went from a 48-inch waist to 42 inches within a year. And he also noted significant changes in his energy and sex drive.


- David from the UK

After several years of constantly feeling tired and struggling with physical activity and sleep, his doctors identified a T count that was lower than it should be for his age. His testosterone levels were up to normal, and he’s back to working out within weeks of taking this supplement.


- Tony from the US

Jarel’s energy levels and libido had started dropping in his late 20s, and he was struggling to stay ripped. Prime Male seems to have turned things around for him with more energy at the gym and for life in general.


- Jarel from the US

His T count had started naturally dropping with age, but this meant he struggled to work out enough. He’s noticed a boost in energy that allows him to train harder at the gym since taking this supplement.


- Jordan from Canada


Is Prime Male a Steroid?

No, Prime Male isn’t a steroid. It uses herbal ingredients that trigger natural testosterone production in the body. Men of all ages could benefit from such a boost through positive effects on their physical shape and mental health.

Can you take Prime Male every day?

Yes, you can take Prime Male every day. But you should also plan for regular off-cycles that should last a week to 10 days. This should help avoid your body getting used to the ingredients, that would result in fewer positive effects.

Should You Buy Prime Male Testosterone Booster?

Yes, this has become the main testosterone supplement we recommend to our clients. Our nutritionist was impressed with the natural ingredients, and our clients confirmed that they got better results than using other supplements.

There are also many positive Prime Male review comments in forums and Facebook groups, which is an encouraging sign.

Order yours today and then report back to us on social media if you think this is the best testosterone booster.
