Prime Male - Editor's Choice

Prime Male Vitality ComplexPrime Male is one of the best male vitality supplements on the market. It’s an all-natural T-booster that raises testosterone levels safely and effectively. This little red pill will change your life by fighting those bothersome symptoms of low T.

It can help you revitalize your energy and maintain a healthy and active lifestyle. You won’t have to bear the burden of being tired and depressed. In fact, you can build muscle mass, burn more fat, and enhance your cognitive ability.

So, what makes Prime Male so effective? Here is the ingredient breakdown.

But first…

Brand Overview

Prime Male is a testosterone booster under the Roar Ambition umbrella. This UK-based company specializes in organic supplements that help men regain their masculinity. It has been in the industry since 2014, helping revolutionize various formulas.

Prime Male stands out from its close competitors for various reasons. It conducts extensive research and only uses scientifically-backed natural ingredients. It covers all the bases and utilizes high-quality ingredients to ensure you get the best results.

Prime Male Ingredients

  • 30 servings per container
  • 7.5 mg Vitamin B6 per serving
  • 45 mcg of Vitamin K2 per serving
  • 5000 IU Vitamin D3
  • 100 mg Magnesium
  • 1600 mg D-Aspartic Acid Calcium Chelate
  • 30 mg Zinc
  • 120 mg Asian Red Ginseng 4:1 Extract
  • 300 mg Mucuna Pruriens extract
  • 60 mg Luteolin
  • 160 mg Nettle root 10:1 extract
  • 5 mg Boron
  • 10 mg BioPerine
  • 300 mg of Ashwagandha



Prime Male Review

The secret to Prime Male’s success is its ingredients. First, it’s slightly dosed up to ensure you don’t just get the necessary nutrients but also get maximum gains. Second, quality is their primary focus.

Prime Male includes an impressive lineup of natural and safe ingredients. Each has its purpose, not just to fill the formula. For instance, the 1600 mg per serving D-Aspartic acid boosts your T levels and improves dopamine production and sperm quality. According to a study by the NCBI, it controls the release of testosterone and LH in the testes and pituitary, respectively. (1)

Zinc is another ingredient present in Prime Male. It plays a pivotal role in reversing the symptoms of low testosterone. First, it improves your immune system functions helping your organs remain healthy even with ageing. Second, according to NCBI, zinc encourages the pituitary gland to release the luteinizing hormone and androgen receptors.

Another superb component is Boron. It’s a beneficial mineral in that it helps your body utilize vitamin D, estrogen, magnesium, and testosterone. With this extra support, Prime Male can work more effectively.

Reduced testosterone production may lead to an imbalance of estrogen, which is why Prime Male contains luteolin and nettle. Luteolin is a flavonoid that helps block estrogen production. That improves muscle mass and tissue development. On the other hand, nettle stops testosterone from converting to estrogen.

Prime Male Price

A three-month supply of Prime Male testosterone booster supply will cost you $225.00 with free shipping in the US & UK. At the time of this publication, the brand is giving an extra free one-month bottle.

A two-month supply of Prime Male costs $150.00, while a single bottle equal to one month costs $75.00.

Prime Male Customer Reviews

Prime Male enjoys good ratings among users. It has an average of 4/5 stars on Amazon, with over 86% above three stars.

Most customers attest that it increases their testosterone levels to boost their energy and confidence. One user called JM. Batista wrote, “I have been using this product for over a year. I can tell you that they will change your life, this work, and never feel any secondary effects.”

Another one called Leo Monteer said, “This stuff increases vitality. It’s the only supplement I’ve ever bought that works as advertised. This stuff puts the proverbial lead back in pencil.”

We also saw a few complaints about the price. Although people thought it was a great product, they said the price was steep for their budget. Overall, the majority of users gave the product a thumbs up.

Hunter Test - Best T-Booster Without Side Effects

Hunter TestAnother best testosterone booster on our list is Hunter Test. It’s a premium natural T-Booster that helps men improve their testosterone levels and reinvigorate masculinity.

Hunter Test will enhance your physical strength, muscle mass, stamina, motivation, energy, and sex drive. Even better, it can help you shade off extra weight and improve overall well-being. It optimizes the effect you put into healthy diets and regular exercise to ensure maximum results quickly.

Hunter Test contains top-notch ingredients that are safe and effective. And like Prime Male, it’s slightly dosed up to provide that immediate and maximum effect.

So, what should we expect in each pill? Keep reading to find out.

Brand Overview

Hunter Test is another Testosterone booster from Roar Ambition. While the company is relatively young, it has some of the best supplement formulas.

Hunter Test stands out by providing premium natural ingredients in each pill. The brand follows strict quality control measures to ensure its manufacturing process meets the required standards. As a result, you get a consistent quality product with maximum results.

Hunter Test Ingredients

  • 30 servings per container
  • 5000 IU of Vitamin D3 per serving
  • 150 mcg of Vitamin K2 per serving
  • 200 mg magnesium
  • 30 mg Zinc
  • 3000 mg D-aspartic acid
  • 300 mg Ashwagandha root extract
  • 300 mg Panax ginseng root extract
  • 200 mg Indole-3-Carbinol
  • 10 mg Boron



Hunter Test Review

To be able to claw back losses due to low testosterone, Hunter Test utilizes some of the best well-dosed natural ingredients.

One of them is Ginseng. This Asian root extract contains antioxidants that contribute to energy ignition. According to the NCBI, it regulates dopamine, supports testosterone production, and lifts libido.

Here you get 3000 mg of D-aspartic acid per serving, a proven ingredient known to increase testosterone. This amino acid affects the neuroendocrine function in the brain’s pituitary gland. As a result, your body produces more testosterone which will bolster your muscle mass and accelerate fat loss.

On top of that, the herbal extract Ashwagandha possesses qualities that actively balance hormones, reduce stress, and increase energy levels. It boosts fertility, fat reduction, cognitive function, cardiorespiratory endurance, and muscle growth.

Another exciting ingredient found in the Hunter Test is the Indole-3-Carbinol. It’s found naturally in cruciferous vegetables like cabbages; this extract inhibits the enzyme aromatase.

Aromatase is an enzyme that lowers testosterone by converting it to estrogen. Men with medium to lower T-levels don’t need this enzyme, so I-3C prevents it from taking effect.

Hunter Test Price

Three bottles of Hunter Test Testosterone booster will cost you $270.00. As per the date of this publication, the brand is offering one extra bottle for free if you buy this package.

The two-bottle package costs $180.00, while one bottle worth a month’s supply costs $90.00.

Hunter Test Customer Reviews

Unfortunately, we only saw a few reviews online. However, the few we found were overwhelmingly positive. On the brand’s website, Hunter Test had a 5/5 star rating.

One satisfied user called Dan Man wrote, “I’ve recently wondered if my T-levels were a little low because I’ve felt a little flat and just not myself. I did a bit of reading around and decided to go for a T-booster. It had to be natural and the best on the market. I found Hunter Test and decided to give it a go. I’m so glad I did! After a few weeks of taking it, I’ve noticed a boost in my mood, more energy, and drive to hit the gym to get in my best shape ultimately. That’s my next job. And the Hunter Test will help me get there.”

We found a few negative comments on Reddit, with several people complaining about the number of pills taken per day. Those people with pill-swallowing difficulties said they are too many. However, all of them agreed that the product works.

TestoFuel - Best For Building Muscle

TestoFuel- The Best Anabolic Support ComplexTestoFuel is among the best testosterone boosters for its proven ability to increase testosterone production naturally. It has similar ingredients to Hunter Test but with a few twists.

TestoFuel speeds up weight loss (including that stubborn belly fat). It also powers muscle growth and lifts self-confidence. Additionally, it helps you recover faster from minor injuries and enhance your mood.

Its primary path of action is to stimulate the production of luteinizing hormone, a precursor to testosterone. It also regulates glucose and insulin, two hormones that control body fat and muscle growth.

Brand Overview

TestoFuel is also a product of Roar Ambition, which is no surprise. The company has put in the work to formulate industrial-leading testosterone boosters.

This sports nutrition company goes above and beyond to produce superior products. For example, they let third-party labs test and double-check purity, potency, and label accuracy. That’s not all. Roar Ambition also offers a 30-day money-back guarantee.

So, what does TestoFuel contain?

TestoFuel Ingredients

  • 30 servings per container
  • 18 mcg Vitamin K2
  • 4000 IU Vitamin D3
  • 70 mg Magnesium
  • 180 mg Maca Root Ext
  • 2000 mg D-Aspartic Acid
  • 100 mg Asian Red Panax Ginseng Extract
  • 50 mg Fenugreek Seed Ext
  • 100 mg Oyster Extract
  • 8 mg Boron



TestoFuel Review

Much of the ingredients you find in the Hunter Test are also included in the TestoFuel. So, that means the benefits of things like D-aspartic acid are also present in this one. However, it has a few extras that set it apart from other testosterone boosters.

TestoFuel contains a surprise element such as oyster extract. It’s rare in testosterone boosters, but it works great in this one. This ingredient has been an alternative medicine for centuries.

Oyster extract is an excellent source of zinc, which, when combined with other ingredients, improve testosterone production. As a result, you get an enhanced sex drive and sexual health.

Another excellent ingredient that makes TestoFuel a top-notch T-booster is Maca root extract. It’s a herb with roots containing compounds that improve your stamina, workout endurance, mood, libido, and sleep quality, even in old age. And that’s not the only herbal extract.

There is the fenugreek seed extract. It can boost metabolism, physical strength, fertility, and testosterone production. It’s also a natural way to reduce inflammation. Besides these ingredients, many studies point out the efficacy of magnesium, Boron, and Vitamin D3. (2)

TestoFuel Price

TestoFuel is available on the brand’s website. The three months supply plus one free battle goes for $195.00. You also enjoy free delivery worldwide and free workout videos & nutritional E-book guide.

The two-month supply goes for $130.00 with free delivery in the US and UK. This one also guarantees a detailed nutritional E-book and an easy-to-follow video program.

The last offer is the single bottle worth one month’s supply at $65.00. The brand offers free delivery in the US and UK.

TestoFuel Customer Review

Like all other products from Roar Ambition, TestoFuel has seen its fair share of customer reviews. Most users on the brand’s website talk positively about the T-booster.

They cite increased energy, libido, and improved muscle gain as some of the benefits they experienced with TestoFuel. There are even photos and video evidence to prove their claims.

On Amazon, the TestoFuel testosterone booster enjoys a 4.3/ 5-star rating with over 263 reviews. Of these comments, 90% gave it three stars and above. That shows how effective this product is.

One reviewer wrote, “I’ve tried several. This one is the best, but I’ll keep this review basic. Gives me more energy and sex drive. Helps keep weight off. The only downside is taking one pill four times a day.”

Another one said, “I purchased it since I’ve been getting tired after work. Safe to say, after taking one month per the regiment, I no longer feel drained after work. I feel the endurance. I lost 10 pounds, used to be between 200 and 205, and am down to 190.2. I weighed myself yesterday. I don’t hit the gym as much as I would like, but it makes a difference if you eat healthily and cut sugars and bread. My work is very physical, and I have noticed some muscle gain. I was skeptical, and the price was a little high, but It works for me.”

TestoPrime Review

Anyone with low testosterone levels is likely to experience more fatigue than usual. Even simple tasks can become difficult.

TestoPrime is a testosterone booster that will help you get through your days with the energy to spare. It contains pomegranate, Vitamin B6 & D3m, and Ashwagandha, providing long-lasting endurance.

Ashwagandha is a herb with roots that contains compounds with a history in ayurvedic medicine. Consuming it helps with muscle mass, fertility, cardiorespiratory endurance, fat loss, brain function, and digestion.

Pomegranate extract is another crucial ingredient of TestoPrime. According to the NCBI, it enhances the efficiency of blood flow and reduces LDL cholesterol, which are both factors in low T levels. It also increases libido and reduces fatigue. (3)

Meanwhile, Vitamin B6 and D3 are some of the most vital nutrients in testosterone production. Vitamin B6 drives cardiovascular function & cognitive health and regulates testosterone. On the other hand, Vitamin D3 helps with the absorption and retention of calcium. As a result, you get denser bones, physical endurance, immunity, and improved cognitive abilities.

TestoPrime Price

TestoPrime is available on the brand’s website in three packages.

  • One bottle (one month supply)- $59.99
  • Two bottles plus one extra free – $119.99

TestoPrime Customer Reviews

Most users love TestoPrime. Although we didn’t find many reviews, those available were mainly positive.

One user on Trustpilot said, “After one year of taking two a day, my feeling better was confirmed with a testosterone test. 50+ points isn’t a huge gain, but it is noticeable. And it’s not going backward anymore! I recently upped my dose to the recommended four daily and noticed a difference again. Not a huge fan of 4 pills every morning but worth the results!”

Another one wrote, “Testoprime is a great product. I’ve been using it for four months now. I lost fat, gained some muscle mass, and somehow I’m growing hair on a spot that was gone. My energy levels are great. I can see the difference!”

Unfortunately, the brand offered very few customer reviews. However, based on the ones we found, TestoPrime was broadly accepted as a quality and effective T-booster.

We also saw a few complaints about the price. People thought that although it worked perfectly, it was a little too expensive compared to other supplements on the market.


Testosterone boosters can be great for anyone battling low T levels. Taken alongside regular exercise and a healthy diet, they can help you feel better and gain muscle mass. There are many, but the four above are the best in the market.

Remember to talk to your doctor before taking any supplements, especially if you’re on medication.
