The Top 12 Best Testosterone Boosters That Work (June 2022)

Have you been feeling less energetic and more irritable lately? If so, your testosterone levels could be to blame. We all know that as we age there are a variety of bodily functions that become less effective and it can be frustrating to not have the same energy or sex drive as before.

However, there is a way to increase those master male hormone levels naturally without prescriptions or needles! The best testosterone booster supplements contain natural ingredients that can help men increase muscle mass, boost sex drive, reduce body fat, sharpen focus, and restore vitality.

After thoroughly researching the market for testosterone boosters and the recommendations made by experts, the scientific community, and traditional medicine, our team narrowed down the list to the 12 best testosterone boosters that help in stimulating natural testosterone production.

  • Prime Male
  • Testo 911 by PhytAge Labs

Let’s begin at the top and review the best testosterone booster of 2021 to see how these testo enhancing supplements stack up in comparison to one another as the stiff competition heats up in a battle to be crowned the number one, most recommended formula for overcoming low T levels in aging men.

Barbarian XL by Zenith Labs


Manufactured by long time industry innovator Zenith Labs, Barbarian XL is a cutting-edge formula that features five all-natural ingredients (i.e., Boswellia Resin Extract (Frankincense), Ashwagandha, Tongkat Ali, Shilajit, and Korean Red Ginseng) that work synergistically to help the body maintain sexual vigor, energy levels, and one’s overall confidence. Along with powerful vitamins and minerals such as vitamin D, vitamin B6, magnesium and zinc, these ingredients are supposedly responsible for yielding results that promote healthy levels of testosterone according to the doctor who formulated this unique master male hormone booster by helping increase the bioavailability and absorption of the Boswellia extract and the four other superchargers.

With no strange chemicals and tested by a third party independent lab to verify the accuracy of potency and purity in the Barbarian XL testosterone booster supplement, a reassuring factor, in this case, is that Barbarian XL is formulated by a naturopathic doctor and chief medical officer of Zenith Labs, Dr. Ryan Shelton.

The high efficacy testo booster supplement is by newly formed PrimeGENIX, who may be new, but the leadership behind the formulation is not new to the game.

Testo-Max by CrazyBulk


CrazyBulk is a supplements manufacturer that aims to introduce natural and legal alternatives to steroids in the market. Their take on testosterone boosting supplement is called Testo-Max and is deemed an alternative for Sustanon. Sustanon (Su) is described as an oil-based injectable anabolic-androgenic steroid that has been linked to continuously release testosterone into the blood for periods ranging anywhere between three and four weeks [3]. The drawback that stems from taking Su can easily range from nausea and acne to changes in cholesterol levels and liver function or, worse, heart failure.

To avoid complications from taking Su, CrazyBulk Testo-Max seems like the more reasonable bet as it includes ingredients such as D-Aspartic Acid, Nettle Leaf Extract, Ginseng Red Powder, and Fenugreek, among others. Together such ingredients may promote extreme strength, enhance performance, and reduce recovery time. Matter-of-factly, this solution is deemed suitable for men who have to alternate between bulking and cutting cycles.

Main Ingredients:

L-Aspartic Acid, Magnesium (from Magnesium Gluconate), Fenugreek Extract 4:1, Nettle Leaf Extract 4:1, Red Ginseng Extract 4:1, Zinc (from Zinc Citrate Dihydrate), Boron, Vitamin B6 (from Pyridoxal-5-phosphate), Bioperine®(05% Piperine), and Vitamin D2 (Ergocalciferol)

Dosage: Take four(4) capsules with water approximately 20 minutes before your breakfast, or as directed by your doctor. Follow these directions whether you’re working out and on rest days too!

  • Faster muscle growth, boost athletic performance and reduces recovery time

Testogen is a testosterone booster that emphasizes not only total testosterone but also free testosterone levels. This formula supposedly reflects the coming together of science and nature, where the duo can enhance male health, all while blocking hindrances such as female sex hormones.

As for how it is meant to work, when the luteinizing hormone is lower in counts, men are likely to experience falling testosterone rates. For this reason, the team responsible for Testogen insists that increasing the production of this particular hormone will stimulate Leydig cells in the testes essential for producing and releasing testosterone.

Next, this formula is believed to increase free testosterone in the body. Earlier, we mentioned that most testosterones are bound to SHBG. Well, this prevents them from being usable.

Main Ingredients:

D-Aspartic Acid, followed by Fenugreek Extract, Zinc, Vitamin D3, Korean Red Ginseng Extract, Boron, Nettle Leaf Extract, Magnesium, Vitamins B6, and K1, and Bioperine.

Before jumping into how the ratings were calculated for the top 12 best testosterone booster supplements on the market for sale in 2021, here is a final overview of the top rated testo pills for men along with a brief description of what makes each of these formulas stand out from the dozens and dozens of products that were analyzed in the making of this review:

  • the tried and true testo pills for men over 40 with low T levels

Now, as most already know, the devil is in the details when it comes to fine tuning a list of the best testo boosting products to buy. After listening to what customers say, seeking any scam complaints or negative side effects, combing through the testimonials, ingredients and company backgrounds, here is the make-up of how the ranks were factored in for each brand.

A Detailed Look at the Ranking Criteria

By now, it should be evident that many of the listed testosterone boosting supplements have similar traits. Well, that’s because we stuck by our ranking criteria prior to scavenging for testosterone boosters. Bear in mind that the following factors are based on extensive research and experts’ input on the matters.

The purpose of ranking criteria is to give everyone a general sense as to how one can identify the best testosterone booster supplement over the weaker types. Said list is certain to vary depending on one’s respective beliefs, preferences, and expectations. Nonetheless, here’s ours:

1. Ingredients

The number one factor that should be assessed before buying a testosterone booster is the ingredients list, namely, the research evidence that the ingredients have in relation to boosting testosterone levels and its related symptoms.

2. Concentrations

The per-serving ingredients’ concentrations need to be thoroughly evaluated to have a general idea as to whether the suggested prices are reasonable and if the solution itself is truly effective. If the concentrations are too low, results will be prolonged, while anything in excess might worsen the situation. Therefore, a balance between the two extremes needs to be measured for men to experience heightened testosterone levels.

3. Company Background

Company background is a simple yet meaningful factor that allows individuals to either connect or stray away from a solution. If a testosterone booster is advertised without any mention of the manufacturing company, mission statement, values, and/or contact information, its overall legitimacy will be heavily questioned. Knowing what a company stands for and why it is that they are in a particular business gives individuals hope that the right processes have been taken to guarantee safety, purity, quality, and effectiveness.

4. Transparency

Transparency and company background go hand in hand. The more information available, the more comfortable and confident consumers become before placing an order. We made sure to find companies that were completely transparent in what they were offering. Some indicators of this include making the supplement’s facts available, providing a thorough frequently asked questions section, explaining briefly the thought process that went behind picking the ingredients, quality control, and above all, contact information.

5. Features

In general, knowing that a supplement carries a wide range of features excites consumers because it might feel as though they received a solution that is worth every penny spent.

One major feature that everyone should look out for is whether the supplement contains soy products. Why? Well, soy products have been linked to increased levels of estrogen and, therefore, low testosterone. Another feature that we were adamant to see is the use of natural and legal ingredients. In the past, steroids were highly encouraged, but evidently, times have changed, and steroids are now becoming of less importance.

6. Return Policies

We believe that if a company has the best product, they will back it up with guarantees so you can feel confident in your purchase from them no matter what.

The best testosterone boosters, including all the brands ranked on our list, give customers a hassle-free way to return items.

7. Advertised Benefits

Regardless of the industry in which individuals are looking to make a purchase, the first thing one is likely to search for is the listed benefits and how they compare to verified experiences. By advertised benefits, we mean the results that stem from taking said supplements, whether they are realistic or overly exaggerated, and to what level the benefits are linked to testosterone boosters.

8. Price

Although price should be one of the last factors to reflect upon, it remains one of the firsts that consumers are attracted to. Men in dire need of the best testosterone booster supplement are willing to put the effort towards positive change should not be turned away. Hence, we decided to limit the prices between USD 49 and USD$80.


What Science Suggests About Testosterone Boosters

Our main focus in regard to how the scientific community perceives testosterone boosters rests in the included ingredients. Honestly, there are just so many ingredients that might affect testosterone production; hence, to further simplify things, our top 11 testosterone boosters were compared amongst each other to see which ingredients were reoccurring. In so doing, we narrowed the list down to eight ingredients that warrant investigation.

Here is an analysis on the top reoccurring eight:


Ashwagandha is an Ayurvedic herb that acts as an adaptogen to support the body’s ability to better manage stress. Upon researching the herb’s benefits in male health, one study that looked at the herb’s effect on fatigue, vigor, and steroid hormones in overweight men aged 40 to 70 caught our attention.

Conducted over a span of 8 weeks, this randomized, double-blinded, placebo-controlled, crossover study indicated that ashwagandha intake was linked to an 18% greater increase in DHEA-S and 14.7% greater increase in testosterone. However, when it came to factors such as cortisol, fatigue, vigor, or sexual well-being, there was no difference between the control and placebo groups [5].

Finally, we have a study that was curious to see whether ashwagandha intake contributes to muscle strength and mass. This randomized, double-blinded, placebo-controlled clinical study consisting of 57 men found that compared to the placebo subjects, the control group experienced greater increases in muscle growth on both the bench-press and leg-extension exercises. In addition, their arms and chest are said to have increased in size, while the risk of injury significantly dropped [7].

Korean Red Ginseng

Korean Red Ginseng (or commonly referred to as Asian Ginseng) is a plant that has been used as a treatment to enhance the immune system. As per one source that reported on the plant’s proven traits, it was shared that its ginsenoside compounds can prevent inflammation and increase antioxidant capacity in cells. In terms of male health, close to eight studies were reported on its ability to treat erectile dysfunction.

For instance, one study that treated men with Korean Red Ginseng supposedly had a 60% improvement in erectile dysfunction-related symptoms compared to a 30% improvement found within the group that was given conventional medicine [8]. Another study with a similar goal and a larger sample size (n = 86) found improvements in erectile dysfunction and overall satisfaction. This was linked to a dose of 1000mg of aged ginseng extract, which was ingested over the course of 8 weeks [8].

One review that looked at the effects of ginseng on male reproductive function highlighted a number of animal studies that have proven its effects. Namely, they wrote that there is a positive correlation among ginseng, libido, and copulatory practices, adding that “these effects have been confirmed in case-control studies in humans” as well.

Other areas of improvement include sperm quality and count of healthy individuals and patients with treatment-related infertility. As previously mentioned, these benefits have all been linked to the plant’s rich source of ginsenoside compounds [9].

D-Aspartic Acid

It is a type of amino acid that is involved in the production and release of testosterone throughout the body. One review to summarize available evidence on the effects of D-Aspartic Acid on serum testosterone levels concluded that in their analysis of 23 animal studies and 4 human studies, it was discovered that results were more consistent among male animal studies than male human studies. Hence, the researchers stressed the importance of well-designed human clinical trials with larger sample sizes [10].

Another study that was published around the same time looked at the effectiveness of D-Aspartic Acid on basal testosterone levels of resistance-trained men. Aged between 18 and 36 years, these men were selected based on their regular resistance training. After 12 weeks, the team found that the amino acid was ineffective at changing testosterone levels or positively affecting training outcomes [11].

What caught us by surprise is the findings of one source that reviewed a study conducted over the span of two weeks. When subjects were asked to take a high-dose supplement of 6 grams per day, it led to a decrease in testosterone in young men who trained [12]. Like the above source said, more research is definitely needed for this ingredient. It is unclear as to why the age group has been restricted to younger men. It is also unclear why studies on its effects when combined with other testosterone boosting ingredients were not addressed.


Fenugreek is a clover-like herb that is mainly grown in Mediterranean regions, Southern Europe and Western Asia. To evaluate the efficacy and safety of the glycoside fraction of fenugreek seeds on muscle anabolism and androgenic hormones, among others, a team of researchers set out to find 60 healthy subjects who would be given this herb for 8 weeks with a resistance training program. In the end, they found that the herb significantly improved anabolic and androgenic activity in these men. Moreover, their body fat levels were also improved without any reduction in their muscle strength [13].

Another study with healthy men ranging between the ages of 43 and 70 also found significant improvements. Precisely, these men were given fenugreek supplementation for 12 weeks, and consequently, both total serum testosterone and free testosterone increased in comparison to the placebo group. This permitted the team to affirm that fenugreek is an “effective treatment for reducing symptoms of possible androgen deficiency, improves sexual function and increases serum testosterone in healthy middle-aged to older men.”

Vitamin D3

Vitamin D3 is a fat-soluble vitamin that supposedly helps with calcium and phosphorus absorption. In fact, this vitamin is crucial for upkeeping healthy and strong bones. In terms of male health, we stumbled upon a study that examined the role that vitamin D3 might play in boosting testosterone production. The selected subjects were healthy, overweight men who underwent a weight reduction program. Split between a control and placebo group, the former was given vitamin D for an entire year. As a result, the team found a significant increase in total free and bioactive testosterone levels [15].

One of the researchers of a study titled, Vitamin D and sex steroid production in men with normal or impaired Leydig cell function, Martin Bloomer Jensen, explained the following about their study:

“What is new about this study is that we can show that vitamin D influences testosterone production. There appears to be a direct link, and one may speculate whether supplementation of vitamin D for vitamin D-deficient men may give a clinically relevant increase in testosterone.”

As far as research goals go, the team did manage to find that vitamin D affect testosterone production directly in the testicles. That said, Bloomer made the case that a larger study will be needed to make firmer conclusions. For the time being, he is optimistic that vitamin D is helpful because it has been proven to support men who have been suffering from low sperm production and infertility [16].

Finally, we stumbled upon yet another study that evaluated the efficacy of vitamin D supplementation on serum testosterone levels in men with low testosterone levels at the baseline. To our surprise, no significant treatment effect was found between the vitamin D3 group (i.e., intake of 20,000 IU) and the placebo after 12 weeks of intake. The same appears to hold regarding “free testosterone, free androgen index, SHBG, estradiol, follicle-stimulating hormone, luteinizing hormone, metabolic characteristics and body composition [17].”


Zinc is a nutrient that is naturally found in cells throughout the body. Its main role is to scavenge and eliminate free radicals and toxins, while other responsibilities include protein and DNA production and contributing towards the genetic material in all cells [18].

One study that explored the relationship between cellular zinc concentrations and serum testosterone of 40 healthy men between 20 and 80 years of age found a significant correlation. Specifically, the team noted that dietary zinc restriction was associated with a decrease in serum testosterone after 20 weeks [19].

Upon searching studies about erectile dysfunction, one that analyzed the effect of zinc on sexual competence of male rats. Researchers were able to show that zinc therapy did, in fact, improve sexual competence and that such an effect was dose-dependent. Having said that, more studies might be needed to ensure that the same improvements hold in cases of sexual dysfunction [20].


Magnesium is a type of mineral that oversees hundreds of enzymic reactions in the human body. It mainly tends to muscle and nerve function while taking extra measures to support immune function and blood pressure levels, writes one source [22]. A study that was performed to assess how four weeks of magnesium supplementation and exercise might affect free and total testosterone levels concluded that both types of testosterone levels increased at rest before and after exercise. The increases were supposedly more prevalent in those who exercise as opposed to sedentary individuals [23].

In addition, one review that looked at the relationship between testosterone and magnesium supplementation highlighted that men “with impaired magnesium status and [testosterone] deficiency could benefit from magnesium and/or [testosterone] treatment targeting physical performance.” A common sentiment that was expressed on numerous occasions is that larger samples need to be collected to affirm such results.

In all truth, the authors of this piece believe that if such results can be replicated with larger data, then the combination of hormonal and mineral replacements can go a long way, especially when it comes to preventing “the onset of disability in the elderly [24].”

Vitamin B6

Vitamin B6 is an essential nutrient that is involved in the processes of gluconeogenesis and glycogenolysis, and immune function. A rats model with a mission to administer vitamin B6 supplementation to assess testosterone levels concluded that rats deficient in the nutrient either have a reduced rate of testosterone production or an increased rate of metabolic clearance [25].

Another study that combined vitamin B6 with zinc and magnesium (i.e., also referred to as ZMA) indicated that the right ratio of ZMA led to an increase in testosterone after 8 weeks of ingestion. However, any additional increase in concentration did not bring any added benefits [26]. A source on a mission to shed light on testosterone-boosting solutions wrote that B6 is crucial for processing and breaking down protein, carbohydrates, and fats.

In addition, it is trusted to enhance cognitive function, energy levels and possibly, testosterone production. Most of all, when individuals are vitamin B6-deficient, the brain is triggered to increase estrogen production, which, as we all know, is a female sex hormone [27].


FAQ – Testosterone Boosting Supplements

What is the difference between normal and free testosterone levels?

Normal (or total) testosterone levels are those that have been bounded to a protein called sex hormone-binding globulin (SHGB). When testosterones are not bounded to SHBG, they are biologically active or termed “free testosterone.” Even though some limitations need to be reflected upon, total testosterone levels usually serve as a measurement for the severity of hypogonadism.
