When it comes to the market for testosterone boosters, there are a lot of players but only a handful of standout performers. These are usually the top sellers in the market. Comparing these powerhouse testosterone supplements can be challenging as there's usually not that much difference between them. In this article, though, we take on the challenge as we put two of the market leaders in the testosterone booster space head-to-head; TestoPrime and Testogen.
In this article, you can expect the following:
While both testosterone boosters contain science-backed ingredients and positive reviews, we feel that TestoPrime edges Testogen out. The higher dosages, along with the choice of ingredients from TestoPrime, make this the clear winner, in our opinion. Keep reading for a comprehensive breakdown of the two supplements.
TestoPrime is a dietary supplement promoted as a natural testosterone booster. It is made up of a mixture of a dozen organic compounds that are thought to boost the production of testosterone and general male health. Key ingredients include the amino acid D-aspartic acid, which may encourage the release of luteinizing hormone, which in turn may encourage the creation of testosterone, as well as ashwagandha extract, fenugreek extract, and Panax ginseng.
TestoPrime is manufactured by the UK-based company Wolfson Brands Limited. It can only be purchased from the official TestoPrime website.
Testogen is a direct competitor to TestoPrime. It contains one less ingredient than TestoPrime, with seven of those ingredients being the same. Among the unique ingredients in Testogen are magnesium, nettle leaf extract, and boron.
Testogen is marketed more toward younger men than the older target market of TestoPrime. It is manufactured by the UK-based company Muscle Club. The company claims to use top-notch ingredients and cutting-edge manufacturing facilities in order to guarantee the quality and efficacy of its supplements.
Testogen aims to address issues with low testosterone, such as impaired and diminished libido, decreased energy, and potential effects on general well-being. It attempts to distinguish itself in a highly competitive market by stating that it supports healthy testosterone levels with a potent combination of components that have scientific backing.
The ingredients are the engine of testosterone boosters. They, and they alone, determine how effective testosterone supplements will be. Here's an overview of the dozen ingredients, with references to the studies that support them.
D-aspartic acid (DAA) is an amino acid that the body makes on its own, and that can also be found in some foods. DAA is thought to be involved in the control of the synthesis of testosterone. It stimulates the pituitary gland's secretion of luteinizing hormone (LH), which in turn stimulates the testicular synthesis of testosterone.¹ DAA may help the body's normal testosterone release by encouraging LH release.
D-aspartic acid may also enhance the process of sperm formation, which is known as spermatogenesis. It might improve the quality, motility, and overall performance of sperm.²

The popular herb Panax ginseng, commonly referred to as Asian ginseng or Korean ginseng, is a staple of traditional Chinese medicine. Ginsenosides, the active ingredients in Panax ginseng, are thought to be the source of the herb's therapeutic effects. Polysaccharides, peptides, flavonoids, and volatile oils are some of the other ingredients found in Panax ginseng.
Panax ginseng has a lengthy history of use in the past and now the present, for its alleged health advantages. It has been used to boost energy, sharpen cognition, promote immune system health, and raise general well-being. It is also thought to possess adaptogenic qualities, which aid in enhancing resilience and the body's capacity to cope with stress and may help with testosterone production.³
KSM®-66 is a branded form of ashwagandha extract. Ashwagandha, also known as Withania somnifera, is a popular adaptogenic plant in conventional Ayurvedic therapy. It is renowned for its capacity to boost general well-being, lower stress levels, and increase energy.
KSM®-66 Ashwagandha Extract is manufactured by a company called Ixoreal Biomed. It is produced using a unique extraction method that preserves the whole spectrum of ashwagandha's active ingredients, including withanolides, alkaloids, and other bioactive substances.
Although the data is limited, and more studies are required to draw firm conclusions, several studies have suggested that ashwagandha supplementation may support healthy testosterone levels in men.⁴
Traditional medicine has used the herb fenugreek (Trigonella foenum-graecum) for a number of health advantages. Protodioscin, one of the furostanolic saponins it contains, is thought to encourage the production of testosterone. According to some research, using fenugreek supplements may promote normal testosterone levels, boost libido, and increase strength and muscle mass.⁵
Fenugreek has historically been used as an aphrodisiac and to improve sexual health and libido. It is thought to enhance desire and sexual performance, perhaps by boosting testosterone levels.
Fenugreek may also improve insulin sensitivity and blood sugar regulation. It has fiber and other ingredients that may slow down the digestion of carbs and perhaps help control blood sugar levels. However, its impact on blood sugar may vary among individuals, and more research is needed to establish its efficacy.
Green tea (Camellia sinensis), which is made from the leaves of the tea plant, has a high concentration of polyphenols and antioxidants known as catechins. Antioxidant activity is thought to improve general health and may support a number of health advantages.
According to some research, green tea may improve thermogenesis (the body's production of heat) and fat oxidation, which may help in calorie and fat burning.⁶
L-theanine, a substance found in green tea extract, has been linked to better mood and cognitive benefits. L-theanine has a relaxing impact and could assist in lowering anxiety and stress levels. It is thought to improve cognitive performance by interacting with the caffeine in green tea.
Pomegranate has been investigated for its potential to boost the body's synthesis of nitric oxide (NO).⁷ NO aids in blood vessel relaxation and enhances blood flow. Increased blood flow may boost exercise performance and be good for cardiovascular health in general.
Some research points to possible advantages for testosterone levels of pomegranate extract. It might aid in boosting testosterone production or halting its degradation, but more research is needed to completely comprehend its effects on testosterone and its implications on overall hormonal balance.⁸
Vitamin D is an essential nutrient that is needed for maintaining bone health, immune system function, and hormonal balance. Calcium and phosphorus absorption depends on vitamin D, which helps with mineralization and bone health.
Vitamin D is known to have a part in the regulation of hormones, particularly the creation of testosterone. According to studies, low testosterone levels may be related to vitamin D deficiency. In situations where low vitamin D levels are a contributing reason to low testosterone, vitamin D supplements may help people with vitamin D deficiency achieve optimal testosterone levels.⁹
Enzymes involved in a variety of metabolic activities need zinc to function properly. Immune system performance, protein synthesis, DNA synthesis and repair, wound healing, and cell division depend on it. The modulation of hormones, particularly testosterone, is another function of zinc.
Zinc has been investigated for its potential function in the regulation and production of testosterone.¹⁰ It is necessary for the creation and discharge of luteinizing hormone (LH), which promotes the production of testosterone in the testes. Maintaining healthy testosterone levels in men requires enough zinc levels, which may be achieved through zinc supplements.
Normal sperm development and maturation require zinc. It is essential for preserving the sperm cells' form and function. Infertility and sperm quality might be affected by zinc deficiency.¹¹
Vitamin B6 acts as a coenzyme in many enzymatic activities throughout the body. It assists in converting food into energy by taking part in the metabolism of proteins, carbs, and lipids. B6 is also required for the synthesis of important chemicals, including neurotransmitters, hemoglobin, and nucleic acids.
Vitamin B6 is important for the generation and metabolism of hormones like testosterone as well as for hormonal control. It plays a role in the body's conversion of androgens, which serve as testosterone's precursors, into active testosterone forms.¹²
Vitamin B5 plays a vital role in energy metabolism. It is needed for the breakdown of carbs, proteins, and fats into energy, promoting fat burning. It is also involved in the production and regulation of hormones, including testosterone.¹³
There has been a lot of research done on the potential cardiovascular benefits of garlic extract. By encouraging healthy cholesterol levels, lowering blood pressure, preventing platelet aggregation, and increasing general blood circulation, it may improve heart health.¹⁴ These cardiovascular advantages could indirectly improve well-being in general.
Garlic extract has antioxidant and anti-inflammatory qualities. It has chemicals with sulfur in them that function as antioxidants and reduces oxidative stress by scavenging dangerous free radicals. The anti-inflammatory properties of garlic may also reduce inflammation throughout the body.
Black pepper contains a substance called Piperine, which is well-known for increasing the bioavailability of specific nutrients and substances. It promotes greater absorption by blocking specific enzymes in the liver and intestine that break down and remove drugs.
The addition of black pepper extract to supplements may improve the utilization of other active substances in the mixture. It can increase bloodstream absorption and slow down the metabolism of numerous nutrients, including vitamins, minerals, and herbal components, to increase their bioavailability.
When comparing marketing leading supplements, it's not surprising that quite a few of the ingredients are the same. That's because these are the most scientifically credible active ingredients. Seven of the eleven ingredients in Testogen are the same as in TestoPrime. However, the dosages differ. Let's take a look:
The 2352 mg of DAA compares with 2000 mg. Both of them are a little lower than the dosages used in clinical studies, which are between 2600 and 3000 mg.¹⁵
The 40 mg of fenugreek in Testogen is just one-fifth of what you get in TestoPrime. The generally accepted effective dosage to boost testosterone is 500-600 mg per day, so both products fall far short of that level.¹⁶
The Vitamin D in Testogen is dosed at almost double the amount in TestoPrime. The recommended intake is 10-20 mcg per day, so both products exceed that level.¹⁷
The zinc dosage in Testogen is just a quarter of what you get in TestoPrime. The recommended daily amount for adult males is 11 mg.¹⁸
The 40 mg of ginseng in Testogen is the same as TestoPrime. These levels are considerably under the generally recommended dosage of 100-200 mg.
According to some research, adding the trace mineral boron to one's diet may help boost levels of free testosterone by preventing the action of the protein sex hormone-binding globulin (SHBG), which binds to testosterone and decreases its bioavailability. Boron may assist in raising the body's level of active, free testosterone by suppressing SHBG.¹⁹
The plant nettle leaf has been used for a long time in herbal medicine. Nettle leaf includes a variety of bioactive substances, such as sterols, flavonoids, and polyphenols. Nettle leaf extract has been theorized to provide possible advantages for levels of testosterone. It might assist in preventing the action of SHBG, a protein that binds to testosterone and lowers its bioavailability.²⁰
The mineral magnesium helps control the production of testosterone. That's because it plays a role in the testes' conversion of cholesterol into testosterone. Men's healthy testosterone levels depend on having enough magnesium in their bodies.²¹
Magnesium supplements can also have a critical role in healthy muscle function and performance. It improves muscular recovery after exercise, relaxes and contracts muscles, and may help lessen cramping and pain.
The 20 mg of vitamin B6 in Testogen compares with just 5.6 mg in TestoPrime. Some sources recommend not taking more than 10 mg per day.²²
Vitamin K1 has anti-inflammatory characteristics. It might assist in controlling the body's inflammatory response, thus enhancing general health and well-being.²³
Bioperine may improve the other ingredients in Testogen's capacity to be absorbed by increasing their bioavailability.
Wolfson Brands claims that TestoPrime will do the following:
It is claimed that the cortisol-inhibiting effects of some of the ingredients will reduce stress levels by up to 71.6%.
By naturally increasing VO2 max levels to boost nitric oxide, TestoPrime is said to be able to boost endurance by more than 90%.
The improved blood flow that TestoPrime allows is claimed to boost muscle strength by 138.7% due to the greater oxygen and nutrient supply to the muscle cells.
The official website claims that TestoPrime can produce a 12% increase in the body's fat-burning ability.
The energy-enhancing activity of the B vitamins will significantly increase energy levels.
TestoPrime is a safe, natural product. However, as with all dietary supplements, there may be some temporary side effects. These may include:
The official Testogen website lists the following benefits:
Ingredients like Vitamin D, Korean red ginseng, and Vitamins B5 and B6 boost energy production while also reducing fatigue.
DAA, ashwagandha, fenugreek, and zinc are the key testosterone-boosting ingredients designed to stimulate the body's natural testosterone production.
The combination of such ingredients as magnesium, Korean red ginseng, and Vitamin D promotes an increase in stamina and endurance so you can work out harder for longer.
Korean red ginseng and other natural ingredients are said to improve a man's libido, revitalize their sex drive and bring back youthful desire.
The improved testosterone levels that Testogen promotes will boost the metabolism, so you are burning more calories all day long.
Although it is regarded as a safe, natural supplement, some people may experience the following minor side effects:
Wolfson Brands recommends taking TestoPrime every morning before breakfast. Testogen should also be taken in the morning before eating,
The recommended dosage for both TestoPrime and Testogen is four capsules per day.
A one-month supply (120 capsules) of TestoPrime costs $64.99
A three-month supply (360 capsules) costs $129.99
A five-month supply (600 capsules) costs $194.99
A one-month supply (120 capsules) of Testogen costs $59.99
A three-month supply (360 capsules) costs $119.99
A five-month supply (600 capsules) costs $179.99
Both manufacturers offer free shipping and a money-back guarantee.
Yes, based on our expert analysis of the ingredients, combined with real user results, we conclude that TestoPrime is a more effective testosterone booster than Testogen. It has one extra ingredient than Testogen and contains some key 'T' boosting ingredients that are missing from Testogen, including ashwagandha, green tea extract, and pomegranate extract.
Yes, TestoPrime does work in terms of boosting the body's natural testosterone production ability. However, it should be remembered that TestoPrime is designed to be used as a supplement to a healthy diet and exercise, both of which are important factors in boosting testosterone levels naturally.
No, it is not. While TestoPrime might not give the same effects as anabolic steroids, it uses natural herbal extracts to help boost testosterone levels without the nasty and harmful side effects of illegal steroids.
TestoPrime is the best alternative to Testogen as a testosterone-boosting supplement. Three-quarters of the ingredients are the same, with Testogen also throwing in ashwagandha, green tea extract, and pomegranate. Both products are effective testosterone boosters, though we believe that TestoPrime is a slightly more effective product.
No, Testogen will not, by itself, build muscle mass. You need to be doing resistance strength training and consuming adequate amounts of protein to promote muscle growth. Taking Testogen to increase testosterone levels will act as a supplement to that process.
TestoPrime and Testogen are both effective testosterone boosters. As we've seen, they've both got solid research supporting their ingredient profiles. However, TestoPrime provides that little bit more, with the inclusion of 3 more key ingredients and significantly higher dosages on others. As a result, we rate TestoPrime as a more effective testosterone booster than Testogen.
