These T-Booster supplements have been put through Spot Me Bro’s strict testing protocol to find their place on this list. After following a rigorous criterion and referencing the most up-to-date scientific studies, we’ve established their effectiveness and ranked each accordingly.
As a man, your androgens play a vital role in your health [1]. Optimized T-levels can help with:
However, low and unhealthy levels of test may negatively affect wellbeing. As you age, the amount of free-flowing T in your body declines, causing additional health concerns [2]. Men with reduced T may face many alarming symptoms, including both physical and mental degeneration [3].
Because of the impact these androgens have on our lives, a good T-booster must deliver on all fronts, raising T naturally without the risk of adverse side effects.
Raising your T-levels can be accompanied by a plethora of benefits. Therefore, in order to assess exactly what T-boosters can do for men, we need to break down the supplement facts.
Research suggests an increase in test can facilitate:
Healthy levels of test for men vary between 250 – 1100 ng/dL. However, the total quantity pumping through your body can easily be thrown off course.
A busy lifestyle impacted by stress can cause androgen levels to plummet. Successful men may be more exposed to these damaging factors due to their demanding work lives.
Additionally, once a man hits age 40, T production declines by around one percent each year [17]. This can also be an added concern for men as they get older.
Understandably, all these things can add up to better performance. Faster recovery times and muscle growth may help you push out extra reps and sets in the gym. Also, an increase in mood could mean a happier outlook on life, as many men with depression may suffer from low test levels too [4].
What makes a test booster safe?
For a supplement to be deemed safe, we need:
For a test booster to be a worthwhile purchase, it needs ingredient servings supported by scientific studies. Any less or more is a sign of a poorly-balanced product.
One thing we always look out for is the use of proprietary blends. These are undisclosed amounts of unknown compounds or chemicals added by manufacturers. This screams unreliability and tells us the company has hidden these ingredients for a reason, which raises the alarm on safety.
Rest assured that each of the following T-boosters are completely free from mysterious blends. We never review products deemed as potentially unsafe.
Effectiveness is the key component behind every review. To measure it, we dissect the ingredient profile of every T-booster. We ask the question:
The only way we can know for certain is to delve into the science.

After dominating the competition for years, TestoFuel takes the top spot as the best T-booster available in 2020. It rose to the occasion on all fronts and came through as the most complete, comprehensive package.
It’s easy for supplement creators to promise the earth. However, finding a product that comes up with the goods isn’t so straightforward. When we heard TestoFuel claims to ‘smash down the barriers to growth by opening your T floodgates’, we went in with an open mind. What we found, after personally testing TestoFuel’s product, were these top benefits.
Following extensive research into the science behind each serving, we struggled to find fault with the TestoFuel formula.
Every ingredient has been intelligently selected to deliver results and tactically distributed for optimum effect. The studies lined up and we were impressed.
In comparison to their rivals – TestoFuel’s serving sizes demonstrated incredible value for money.
The first thing that struck us was TestoFuel’s completely natural ingredient profile. We could see the manufacturers had extensively refined their formula, presenting a product free from harmful compounds. Safety was clearly paramount, which aligns with our supplement ethos.
Keep reading to find out why TestoFuel might be the best test booster to accelerate your goals.
D-Aspartic Acid – At a serving of 2300 mg, TestoFuel delivers one of the most optimized amounts of D-AA we’ve seen. According to research, D-aspartic acid can induce test synthesis in the Leydig cells [5]. Consequently, scientists suggest it may be used as a T-booster for infertile men or athletes looking to increase mass and strength [6].
Vitamin D-3 – Research tells us that supplementing with vitamin D can significantly increase both bioactive and free test levels [8].
Vitamin B-6 – Men who are deficient in vitamin B-6 may experience tanked T-levels [10]. Not only that, but it’s thought to reduce levels of female androgens by up to 30% [11]. TestoFuel has cut no corners with over 350% of the RDA for men [12].
Zinc- Zinc is a powerhouse mineral for optimizing male androgens. It can bolster luteinizing levels, promoting better T passage into the blood. The mineral is also essential for male fertility [13]. Deficiency is often associated with hypogonadism, leading scientists to suggest it’s important for modulating serum T-levels [14]. With a contribution of 10 mg, TestoFuel brings a bulletproof serving to the table.
Magnesium – This mineral plays an essential role in optimizing protein synthesis. Therefore, adequate magnesium consumption is integral to promoting muscle maintenance and growth [15]. There is also evidence to suggest that Mg exerts positive influences on T in men [16].
After careful scrutiny, we can confirm that TestoFuel is safe for regular consumption. We dissected the formula and discovered only widely used, scientifically approved test promoting ingredients.
When cross-compared with the relevant studies, we also found optimized servings in each compound. For us, this level of attention to detail is a sign of safe supplementation that doesn’t cut corners. There were no traces of shady and mysterious proprietary blends littered with unknown chemicals.
The creators of TestoFuel have exclusively opted for scientifically-informed servings. As a test booster, it’s one of the best-distributed supplements we’ve seen.
For this reason, we suggest you follow the manufacturer instructions. Taking four capsules throughout the day should help you to reach and maintain optimal levels of T.
TestoFuel also advises consistent, daily supplementation for optimum results.
Out of all the T-boosters we have examined, TestoFuel leads the pack. It stands out as being the most comprehensive formula in the mix, filled with safe and optimized servings. We don’t think you’ll find a better test boosting supplement on the market today.
By taking TestoFuel you should experience the vitality of increased T. Healthy and heightened T levels can lead to improved mood, better energy, and invigorated performance.
On top of this, you should notice substantial positive changes to your body composition. A surge of androgens will promote an increase in lean, powerful muscle which can directly influence fat loss.
When it comes to cost, there’s no denying TestoFuel sits at the upper end of the spectrum. As a premium product, it carries a price tag to represent its status. Yet, we feel the quality of the TestoFuel warrants the fee. Some men may be prepared to pay a little more for such a well-researched supplement.
Summary: In comparison to the other players on the field, we say TestoFuel is one of the standouts. If you’re searching for a safe, well-served, and scientifically-backed test booster, check out TestoFuel.

Securing a solid second position, Hunter Test showcases itself as one of the best test boosters available in 2020. Targeted towards the aspiring and successful modern man, Hunter Test features one of the most potent formulas we’ve witnessed, presented within minimal, luxury-inspired packaging.
Many manufacturers claim their supplement overcomes the competition. Yet, there’s only ever a few that walk the walk – we think Hunter Test might be that product.
Not only does its ingredient profile back-up the claim to boost T, but other important parts of your life too. According to the creators, this supplement will:
Keep reading to find out how Hunter Test could open the door to these T-induced benefits.
D-Aspartic Acid – Studies suggest that D-Aspartic acid influences T synthesis inside Leydig cells [18]. As a result, it is recognized as a reputable test booster for not only infertile men, but athletes looking to increase muscle and strength too [19].
Vitamin D-3 – Scientists believe that nearly 50% of adults are deficient in it [20]. Men who spend a lot of time indoors are at higher risk also. The reason these figures matter so much is that vitamin D encourages optimized T production. Scientists indicate that supplementation boosts both bioactive and free levels of test, making it a valuable ingredient [21].
Indole-3 Carbinol –Indole-3 Carbinol (I3C) is a naturally occurring substance found in cruciferous vegetables. Studies show it to be an effective negative regulator of female androgens and can help protect men from certain cancers [22] [23].
Zinc – Zinc (Zn) is a widely used and recognized T-boosting mineral. It possesses powerful luteinizing- elevating potential, which encourages better androgen flow into the bloodstream. Because of this, scientists believe zinc may play a vital role in modulating serum T-levels [24]. Studies show that men who supplement with zinc can experience increased amounts of free T [25]. Additionally, Zn is indicated to be important for increasing male fertility [26].
Ashwagandha Extract – Ashwagandha is a medicinal plant that has been used by indigenous cultures for over 3000 years. It’s known for its therapeutic effects, which help combat stress, depression and anxiety [29]. Studies indicate this ingredient can help boost T-production by blocking and counteracting cortisol [30] [31]. Plus, further research states Ashwagandha (Withania somnifera) is associated with significant increases in muscle mass and strength [32].
After rigorous inspection, we can confidently say Hunter Test is safe. It hits the mark of effective potency without over-distributing. However, as with any supplement, consideration when assessing risk always comes back to ingredient choice.
Hunter Test is a transparent formula, confirming it’s completely free from proprietary blends. Therefore, there are no hidden chemicals or compounds at undisclosed servings inside its capsules. For us, this is a reassuring sign from a premium quality product.
Furthermore, each high-grade ingredient is backed with extensive scientific research. Every compound included is completely natural and poses no threat to men who consume these servings. We also found Hunter Test to be free from artificial colors, flavors, and preservatives.
Another key point presented from Hunter Test is the location of preparation. According to the manufacturers, this product is FDA and cGMP approved, which means it has followed strict US and UK guidelines. As a universal mark of quality, we feel this bolsters the supplement’s claim of across the board safety.
In order to fully experience the benefits of a product, it must be taken properly.
The people behind Hunter Test suggest a serving guide that appears to be well researched. It is one of the better-distributed test boosters we’ve seen, spreading supplementation evenly throughout the day in large servings.
According to its creators, Hunter Test users should take two capsules, three times a day. In total, this equates to six individual capsules over 24-hours. The manufacturer also states that this daily routine should be consistent for optimum results.
The creators of Hunter Test have broken into the supplement industry with incredible noise. Their debut T-booster delivers on many fronts and features all the key players in its ingredients profile.
According to the people behind it, the supplement will allow you to experience the true benefits of boosted T. We agree with them. Hunter Test users should notice increased confidence, elevated mood, better performance, and higher levels of motivation.
Formulated with the aspiring man in mind, Hunter Test not only looks good, but performs well too. Each all-natural compound and mineral has been carefully selected, which is evident by their alignment with reputable scientific studies.
However, it can’t be denied that such a premium product is accompanied by a considerable price. After all, Hunter Test was developed for aspiring high achievers, and the cost clearly reflects this. It could be argued that the quality of Hunter Test does warrant its value, however, it could be out of the price range for some men.
When placed shoulder-to-shoulder with its competitors, we can confirm Hunter Test has a presence. It’s one of the most potently formulated test boosters on the market, delivering safe benefits in sleek, premium packaging. If you’re searching for a T-boosting supplement to support your aspirational lifestyle, Hunter Test could be the one.

Making it to a podium position is Prime Male, a test booster that comfortably breaks into the top tier.
Targeted toward the man over 30, Prime Male is an all-encompassing T-boosting supplement with an impressive, rather unique formula. According to the manufacturer it was specifically developed for men of this age to ‘sidestep the health issues that low T can trigger’.
Confident with its choice of ingredients, Prime Male presents itself as a complex mix, complete with 12 safe, all-natural compounds. Although this isn’t the most potent profile we’ve seen, it still stands out as one of the most impressively served.
The creators of Prime Male claim their product can help you become the man you once were. They believe it can do this by reinvigorating your T production.
In turn, a reclaiming of optimized T should:
To find out if Prime Male can really back up these claims, continue reading.
D-Aspartic Acid – According to research, this ingredient positively promotes test synthesis within Leydig cells [34]. Consequently, scientists suggest D-aspartic acid can pose benefits for infertile men or athletes looking to intensify muscular development [35].
BioPerine® – According to the manufacturer, studies indicate that this ingredient increases absorption rates of dietary supplements as much as 2000% [36]. The inclusion of this ingredient is to apparently speed up T restoration.
Vitamin D-3 – Known as ‘the sunshine vitamin’, your body produces D3 when hit by sunlight. However, studies indicate that almost half of us don’t experience enough sun exposure, resulting in vitamin D deficiencies [37]. Scientists have also linked low levels of T with insufficient vitamin D intake [38]. Yet, with proper supplementation of the vitamin, men may be able to reclaim healthy test-levels[39].
Vitamin B-6 – Vitamin B-6 works by stimulating androgen receptors that tell the testes to pump T into the bloodstream. Referencing one study on B6-deficient rats, animals deficient in the vitamin show a reduced rate of test synthesis [40]. Prime Male also claim that B6 supports the absorption of zinc and magnesium, which are both in its formula and are said to work synergistically for better androgen balance [41].
Boron – Scientists state that Boron is an impressive trace mineral that benefits the body’s use of T and vitamin D, while boosting magnesium absorption [42]. Consequently, boron also provides benefits besides pure T boosting. It allows various other ingredients to work more efficiently and deliver at an even higher potential.
Fundamentally, the serving size of each ingredient should align with scientific guidelines for safety, as well as effectiveness. Prime Male does this across its entire formula, which bolsters the safety score immediately.
Another marker of a trustworthy product is their ingredient choice. Those within the formula should be natural and pose no risk of negative side effects. Upon inspection, Prime Male only presented reputable, widely-used compounds proven fit for consumption.
As with any top tier test booster there should be no proprietary blends. These are undisclosed mixes of mysterious compounds and/or chemicals hidden within the formula by the creators. For us, this is a huge red flag for safety. Fortunately, Prime Male stands proud as free from dangerous blends.
The final safety validation from Prime Male is a strict manufacturing process. According to their website, each serving is constructed in an FDA-approved facility to Good Manufacturing Practice standards.
For customer testimonials visit the Prime Male website here.
The key to experiencing the full benefits of Prime Male is to follow manufacturer guidelines. This should allow for optimal absorption based on their research.
Prime Male’s serving suggestion seems reasonable. They direct their users to take one capsule, four times a day for ideal supplementation. Each serving should also be swallowed alongside a snack or meal.
This approach is one of the most logical we’ve seen, allowing for steady and even ingredient distribution. Prime Male also state that their users should consistently supplement to experience ‘optimum results’.
Its creators say that Prime Male can help men reclaim their former selves and turn back the clock on male aging. By researching the formula, we can confirm Prime Male could do just that when taken correctly.
Each of the 12 natural compounds are also proven to be safe. If ingested at their prescribed serving sizes, none of Prime Male’s ingredients should cause any harm or negative side effects. We also believe that, due to the lack of proprietary blends, we can put a stamp of safety on Prime Male.
However, the reason this product didn’t reach the upper echelons of best test booster was potency. At 12 ingredients, Prime Male includes one or two non-essentials. A more streamlined formula might have taken it to the top spot.
If you are in the market for the most potent test booster, this might not be it. Yet, the combination of the “dirty dozen” should theoretically make it effective.
Finally, we found the price tag to represent the value. After all, Prime Male is a premium T-booster, boasting all-natural ingredients backed by science. Yet, we must acknowledge that it may be expensive for some. Prime Male certainly sits in the higher price bracket where it competes against our top two choices.

Pros
Performance Lab SPORT T-Booster is a multi-pathway supplement designed to help offer all the benefits of healthy T levels, including muscle growth and fat loss.
This supplement should be especially good for promoting a lean body composition because it uses KSM-66® Ashwagandha — shown to boost fat regulating T [32].
KSM-66® can also be a great physical performance enhancer. According to studies, it’s ideal for boosting strength and endurance in workouts — for even more muscle and less fat [32].
In addition to KSM-66®, Performance Lab SPORT T-Booster has D-AA-CC, standardized Mucuna Pruriens (velvet bean), and Luteolin.
Proposed benefits of SPORT T Booster include:
Ashwagandha (KSM-66®, standardized for min. 5% withanolides) – Ashwagandha can be used for mental relief against issues such as stress and anxiety. This helps it alleviate stress-induced T decline [29] [30] [31]. But the benefits don’t just end with the mind. Other research projects have linked this ingredient with improved muscle size and strength too [32].
D-Aspartic Acid Calcium Chelate –D-AA works by stimulating the pituitary gland to produce more luteinizing. Once released, it then tells the testes to increase male androgen creation. Studies say this amino acid can be used to raise androgens in infertile men as well as athletes [6].
Mucuna Pruriens – This small bean supplies the body with the active ingredient Levodopa. Once in the body, L-DOPA triggers different bioactivities that result in T-production. Much like D-AA it encourages the release of luteinizing too [43]. Mucuna can also work as an inhibitor to prolactin [44], a protease that can cut back the amount of T in your body.
Luteolin – The creators have also decided to add Luteolin, a known aromatase inhibitor. As with many other boosters, this 10 mg measure is to help limit the impact of female androgens [45].
After looking at each ingredient, our team saw Performance Lab SPORT T+ as safe. If you follow the manufacturer guidelines this product shouldn’t cause any harm.
Each of the components inside T+ are natural and of a high-quality. They’re also backed by studies too, which support their serving sizes.
As with any good supplement you can increase the chance of safety. The best way to do this is to follow the manufacturer guidelines. Reliable supplement creators put these together to reduce the chance of side-effects, while still giving you the best amount of ingredients.
Unlike our top three best T boosters, Performance Lab T+ takes a different serving approach. Users only take two capsules once a day.
Performance Lab also recommend cycling this product. Rather than take it consistently for the foreseeable future, they say to supplement with T-Booster for four weeks, then take two weeks off.
With all this in mind we recommend taking T-Booster with breakfast. That way you’ll allow your body time to digest its ingredients and support test levels throughout the day.
T+ provides you with what you need if you’re looking for a budget-friendly natural T booster. But depending on what you’re looking for, this smaller amount of ingredients might be a negative. If you want support for your physique or energy levels in much higher amounts and with more variety, T+ might not be the best choice. While it should help these things by contributing to test levels, it isn’t as packed with additional vitamins and minerals like other supplements on this list.
With a NutriCaps® Pullulan capsules, this product is vegan friendly. Their whole contents are GMO and soy free too, which may appeal to more health-conscious individuals.
So, if you’re in the market for a mental performance, stress beating and wellbeing-based product, try T-Booster. It’s a simple, streamlined, four-ingredient supplement that might suit your goals.

Pros
Finishing in fifth place is the highly touted EVL Test by EVLution Nutrition Supplements. Its creators call it a “Science Based T Support Complex!” and it’s still standing the test of time.
EVL Test cuts through a lot of the noise on the market with its tried and tested formula. Within the mix are all the regular, essential T booster ingredients we expect to see. To us, this puts the product off to a great start.
There are also one or two extra compounds not found in our previous picks. These are the likes of Tribulus Terrestris Extract and DIM, which we’ll inspect later. While they didn’t necessary appeal to us, others might like them.
According to EVLution Nutrition their EVL Test supports:
As always though, manufacturer claims are not proof. To really understand what this supplement can do we’ll inspect its individual ingredients.
Vitamin D3 – Research indicates this vitamin plays a pivotal part in male health [7] [8]. As many modern men are at risk of deficiency, supplementation is a smart move. Therefore, it’s common to see D3 in most high-quality androgen boosters, as supplementation can help elevate lower levels [8].
D-Aspartic Acid – This is an amino acid proven to boost T. Studies suggest it does so by influencing the release of luteinizing, which signals to the testes to make more male androgen [5]. According to researchers, D-AA can be used to treat lower test levels. Athletes also experience benefits by gaining extra muscle mass [6].
Zinc – Scientists say this mineral can increase luteinizing levels, which encourages better T passage into the bloodstream [13]. Low test levels are a reported side effect connected to zinc deficiency. As a result, research suggests adequate zinc intake is integral to modulating serum T quantities [14].
Fenugreek – Studies have shown fenugreek to increase male androgen production [47] [48]. However, the data isn’t conclusive, as some resistance trained men saw no benefit [49]. Results may vary from person to person.
After careful review our team said this supplement should be safe to consume. None of the ingredients brought about any immediate concern, and the serving sizes seem reasonable. There are also no proprietary blends in EVL Test, so you know exactly what you’re taking. We score this transparency highly.
However, as with all supplements, it’s important to follow manufacturer guidelines. As much as they’re about effectiveness, guidelines are also there for safety. If you decide to ignore them, side effects may occur. You are advised to take a 4-week break after taking this supplement for 12-weeks.
Unlike our previous four products, EVL Test has two options for taking it. Users can either opt for this supplement in pill or powder form.
Each serving should be taken 30-60 minutes before bed on an empty stomach.
We don’t see this as an optimal way to take a T-booster. Our team of experts all agreed it meant a sub-optimal spike in ingredients. Plus, the serving size could be unenjoyable and inconvenient.
Instead, we prefer servings spread throughout the day. Because of this we don’t think EVL Test’s servings are planned as well as others.
Our final choice is a T-booster that’s been on the market for years. It’s become a favorite among men for its affordability and easy accessibility.
Most of the ingredients found in it are backed by scientific studies. EVL Test has a great vitamin and mineral complex too, which should bring about its own benefits.
While none of these ingredients are exclusive to this product, they’re still good for male health. This is especially true of zinc, magnesium, and vitamin B6.
One thing we would say is that this is probably the best budget booster. However, if you can afford it, we would recommend trying the other options in this list.
The serving suggestions for EVL Test is a slight let down and the formula could be better. If EVLution Nutrition were to take out DIM and Tribulus Terrestris we’d score it higher. We’d suggest replacing these with the likes of Boron, Oyster Extract, or Black Pepper Extract.
In short, if you’re searching for a cheaper test booster this might be it. While not all the ingredients line up, most are backed by solid research.
