There’s no debate that male testosterone levels have been on a slow and steady decline for the last several decades — statistics confirm this. Fortunately, if you’re concerned about your T levels, there are many testosterone-boosting supplements available on today’s market that can help you get them back to normal—no syringe required. 

However, not all supplements are created equal. Each brand offers its own “optimized” blend of natural, herbal ingredients and essential vitamins and minerals. How are you supposed to know which product offers the best bang for your buck?

Today, using careful analysis and science-backed research, we will examine the quality, effectiveness, and value of two of the leading testosterone boosters on the market—TestoPrime and TestoGen. Want to see which reigns supreme and is the better investment for your hard-earned dollars?

Read on to learn more. 

Are TestoPrime and TestoGen the same type of product?

These products are designed to perform the same function—sustain and boost natural testosterone production. Whether your low T levels are due to nutritional deficiencies, environmental effects, or aging, these supplements provide resources to optimize your body’s testosterone production while preserving the integrity, quality, and availability of free-flowing testosterone in your system.

Additionally, they help manage and improve the symptoms of low T levels by boosting your energy levels, libido, stamina, fat metabolism, focus, and muscle gain potential so you can achieve the best version of yourself as soon as possible. 

However, the critical differences between TestoPrime and TestoGen are their active ingredients. Each option exhibits a distinct profile of beneficial effects, efficacy, quality, and price while targeting different body parts and having a different testosterone life cycle. 

At first glance, TestoPrime and TestoGen are effectively neck-and-neck, but with closer scrutiny, there’s enough variation that you should get all the facts before making a purchase.

TestoPrime vs. TestoGen: difference in potential benefits 

The core ingredients in both products are designed to optimize your testosterone levels and counteract the havoc that a deficiency may have wrecked on your system. The benefits of this include:

  • Improved overall strength, stamina, and muscle density;
  • Reduced fatigue, enhanced energy levels;
  • Accelerated fat metabolism;
  • Improved sex drive and combating erectile dysfunction;
  • Improved cognition, mental acuity, and focus.

TestoPrime’s supplementary ingredients consist mainly of natural extracts such as ashwagandha, fenugreek, and green tea blended with a cocktail of vitamins and minerals. This provides a well-balanced profile of vitamins and nutrients designed to boost your T levels while supporting other essential aspects of your physiology—such as metabolism, blood pressure, and glucose levels.

TestoGen’s supplementary ingredients support and even enhance the core ingredients, helping create a potent, synergetic testosterone-boosting effect. 

Here’s a quick comparison of the beneficial secondary effects offered by each product:


  • Improves fat metabolism;
  • Reduces stress;
  • Improves blood pressure and sugar levels;
  • Rich in antioxidants which help prevent cell damage and disease;
  • Reduces inflammation.


  • Reduces depression and anxiety;
  • Improves red blood cell count;
  • Maximizes nutrient delivery and absorption;
  • Includes synergistic ingredients that, when combined, boost each other’s testosterone-enhancing effects.

Although these benefits only supplement the value of these excellent T boosters, they could still be crucial for those choosing between the two, depending on their specific needs.

The ingredients

TestoPrime and TestoGen contain a potent concoction of natural, herbal testosterone-boosting ingredients designed to sustain and enhance your body’s natural T levels. The core T booster’s ingredients are much the same but at varying concentrations. The main differences between the two are the unique, supplemental ingredients in each formulation.

Common ingredients for TestoPrime and TestoGen

D-Aspartic Acid

This amino acid supports luteinizing hormone production—which is directly responsible for stimulating the testes to produce and release testosterone.

Amount per serving (four capsules) 

TestoPrime - 2000 mg

TestoGen - 2352 mg

Korean (Panax) Ginseng

This medicinal root helps you overcome the symptoms of low T levels with stimulants that improve erectile dysfunction and libido, boost energy levels, and prevent fatigue.

Amount per serving (four capsules) 

TestoPrime - 8000 mg

TestoGen - 40 mg

Fenugreek Extract

This natural herb contains furostanolic saponins, which can help prevent testosterone from converting into estrogen. It also directly remedies various physiological concerns accompanying low T levels, such as reduced libido, sexual function, energy, stamina, and metabolism.

Amount per serving (four capsules) 

TestoPrime - 800 mg

TestoGen - 40 mg


Optimizes T levels by preventing testosterone conversion into estrogen and oxidative damage to testes’ Leydig cells (testosterone-producing cells).

It’s also essential for thyroid function (metabolism regulation), improving fat burning and energy availability.

Amount per serving (four capsules) 

TestoPrime - 40 mg

TestoGen - 10 mg

Black Pepper Extract (Bioperine) 

The main ingredient, Piperine, improves nutrient absorption, thus enhancing your body’s ability to use the other ingredients in TestoPrime and TestoGen.

Amount per serving (four capsules) 

TestoPrime - 6.68 mg

TestoGen - 5 mg

Vitamin B6 

A central player in the testosterone production process, this vitamin helps maintain normal, healthy testosterone levels. Vitamin B6 deficiency is correlated with testosterone deficiency.

It also helps increase energy, reduces fatigue, and improves focus and mental clarity.

Amount per serving (four capsules) 

TestoPrime - 5.6 mg

TestoGen - 20 mg

Vitamin D 

Vitamin D is a critical nutrient with widespread effects on human physiology. It’s integral for maintaining bone health, reducing inflammation, and maintaining normal testosterone production. Vitamin D deficiency is intricately linked with low-testosterone levels. This is especially important since the primary source of Vitamin D is absorbed through the skin in the presence of the sun’s ultraviolet rays. So, if you live in an area with limited sunlight (in an area with long, dark winters, perhaps), you may not get enough exposure.

Amount per serving (four capsules) 

TestoPrime - 26.66 μg

TestoGen - 50 μg

Unique TestoPrime ingredients

  • Ashwagandha Extract

    This “adaptogen,” derived from the roots of an Asian evergreen shrub, lowers cortisol levels to help relieve chronic stress, reduce swelling, reduce blood pressure, and improve memory.

    Evidence suggests that ashwagandha may also help increase stamina and muscle mass.

    Amount per serving (four capsules)  668 mg

  • Green tea extract (70% catechins)

    Catechins in green tea maintain testosterone levels by preventing testosterone from converting into DHT (elevated levels can cause follicle damage and hair loss).Catechins also reduce inflammation and decrease blood pressure to help relieve chronic pain and heart disease. Its antioxidant properties also help prevent disease.

    Green tea contains caffeine which can make you feel more energized throughout the day.

    Amount per serving (four capsules)  4000 mg

  • Pomegranate Extract (40% ellagic acid)

    A rich source of polyphenols (a potent antioxidant) prevents and even reverses cell damage, reducing chronic disease risk.

    Amount per serving (four capsules)  4000 mg

  • Vitamin B5 (calcium pantothenate) 

    This vitamin is a vital player in testosterone production at the level of the adrenal glands, vital for maintaining healthy, normal T levels. It’s also essential for healthy skin, hair, eyes, immune system, red blood cells, liver, and digestion.  

    Amount per serving (four capsules)  8 mg

  • Garlic Extract

    This ingredient improves blood pressure, preventing heart disease and improving blood flow and energy delivery to your tissues.

    Amount per serving (four capsules)  1200 mg

Unique TestoGen ingredients

  • Boron

    This fundamental element improves how your body uses magnesium, elevating its testosterone-boosting effects. It improves testosterone metabolism, unlocking more of your total testosterone into usable free testosterone. It also buffs your T levels by reducing your SHBG (a testosterone inhibitor) and estradiol (an estrogen form that counteracts testosterone) levels.

    Amount per serving (four capsules)  8 mg

  • Nettle Leaf Extract

    Ligans in stinging nettle inhibits SHBG from binding to testosterone—making it useless—and prevents testosterone from converting into estrogen. Both effects improve the total amount of free testosterone available for use in your body.

    Amount per serving (four capsules)  40 mg

  • Magnesium

    This mineral plays a vital role in testosterone production, ensuring normal, healthy T levels. Deficiencies in testosterone production are linked to magnesium deficiencies. It also boosts your free and total testosterone levels—especially in active individuals. So, the more you work out, the stronger the effect.

    Amount per serving (four capsules)  200 mg

  • Vitamin K1

    This essential vitamin in leafy greens improves vitamin D absorption, enhancing its testosterone-boosting effects.

    It also plays a vital role in blood clotting, improves mood and cognitive function, and lessens symptoms of depression.

    Amount per serving (four capsules)  20 μg

TestoPrime vs TestoGen dosage

TestoGen and TestoPrime offer the same dosage recommendations and requirements: four capsules once a day with a full glass of water. If my math checks out, that makes it about 120 capsules a month—or an entire bottle. For best results, they recommend that you take a dose every day for at least 3 months—don’t skip. Consistency is vital when it comes to testosterone supplements. If in doubt, follow the dosage instructions and recommendations on the label.

TestoPrime vs TestoGen reviews compared


Star value at time of writing: 3.5/5 (537,


Star value at time of writing: 3.9/5 (1967,

Top reviews on the positive end of the scale note a marked improvement in their low T levels, even going as far as getting their blood evaluated to observe their results. All the positive reviews remark the same caveat, however—you must consistently take this product long-term (3+ months) to see results, and it won’t turn you into a bodybuilder on its own.

The lower end of the review spectrum offers the regular slew of complaints—claims of side effects, complaints about the product’s packaging or quality, and a host of general comments stating that the product did nothing for them. However, the efficacy concerns are too vague to take seriously. The product may not work for them (users already have sufficiently high T levels), or they didn’t stick with the program long enough to see results.

Overall, most users are pleased with both products. Users remark on their substantial energy, endurance, and muscle-building potential gains. They talk about how this product allows them to keep up with their grandchildren and stay active despite their age. They remark on how these products heighten their workouts and give them a competitive edge. 

Although these products don’t work for everyone, the results speak for themselves. If your T levels are low, this product may be what you need to normalize your testosterone, boost your energy levels, strength, and vitality—and supercharge your life.

TestoPrime vs. TestoGen side effects and contraindications

Testosterone boosters get a bad rap because of the health dangers of anabolic steroid abuse, testosterone injections, and other “traditional” therapies. However, these products only contain all-natural herbal ingredients, vitamins, and minerals commonly found in food, which pose no serious health risk. Both products boast zero side effects if you heed their dosage recommendations and instructions. 

However, this doesn’t completely rule out the possibility of side effects—the concentration of active ingredients per serving is higher than you’d typically get from a meal. Thus, if you are sensitive to any of the ingredients or take a dose after eating, you may experience mild side effects, such as digestive issues or headaches. 

Also, the long-term effects of the herbal extracts (Ashwagandha and Korean ginger) are unclear. They are safe to use for the short term (less than three months). However, long-term consumption may cause minor side effects such as stomach issues, diarrhea, and vomiting. 

Regardless, very few users experience any ill effects, testifying to the overall safety of both TestoPrime and TestoGen. However, if you are taking any medications, have any underlying health issues, or have allergies or sensitivities to any of the ingredients, consult with your doctor first to see if these products are right for you.

At first glance, each brand has the same price tag, and they do—for a 1 and 3-month supply. For bulk purchases, however, TestoPrime is the better deal. For the large package, you are getting an additional month’s product supply for the same price. Regardless of which brand you decide to go with, buying in bulk (medium or large packages) will get you the best deal. Especially since getting the best results with these products demands taking the recommended serving size (4 capsules) daily for at least three months. If you intend to take the full course from the start, buying at minimum the 3-month package is the way to go. 

TestoPrime and TestoGen both advocate the quality of their products with a generous 100-day product guarantee. If you are unsatisfied with your purchase for any reason, you can get a full refund—no questions asked.

Both products are available for purchase on their website, or from approved sellers on Amazon. Both brands offer worldwide shipping to most (but not all) countries. Check the shipping and returns policy on their websites for more details.

Who should use TestoPrime and TestoGen?

Population-wide T levels have been on the decline for several decades. The reasons for this are complex, but it shows that to maintain normal, healthy T levels or to gain a competitive edge, many men need a little boost. 

These safe, effective alternatives to testosterone injections are designed to help men (18+) return their low T levels to normal and potentially achieve even higher gains. Low T is a complex condition, the result of complex environmental and social stressors. Common conditions that may result in low T levels include:

  • Obesity;
  • Age-related testosterone decline (declines naturally every year from age 30 onwards);
  • Disease or injury to any part of the male hormone production systems;
  • Congenital (at birth conditions);
  • Reduced activity (low muscle density = low testosterone).

These products are also designed to help men with issues related to low T levels, including:

  • Low energy, fatigue, and motivation;
  • Infertility, ED, and low sex drive;
  • Decreased muscle mass, strength, and endurance;
  • Difficulties with concentration, mood, and mental clarity.

These products are also great for bodybuilders looking to optimize their workouts without relying on dangerous testosterone or anabolic steroid injections. 

If any of this sounds like you, TestoPrime and TestoGen may be the answer you are looking for.

Final verdict: The brand that wins

Here we have two comparable products that fill the same role and do their job in remarkably similar ways. They both offer a high testosterone-boosting potential with their potent formulation of well-studied known t-boosting compounds such as d-aspartic acid, fenugreek, zinc, and vitamin D. They both boast high efficacy with a large following of satisfied users across the board. They’re both perfectly safe to consume, with very few side effects reported among users. . 

TestoPrime’s formulation contains ingredients (herb and vegetable extracts) they claim have testosterone-boosting effects—the literature, however, doesn’t support this. Still, these proprietary extracts (ashwagandha, pomegranate, and garlic) can provide significant health benefits. So, if you are looking for a well-rounded supplement that will supercharge your testosterone levels alongside compounds with antioxidant and anti-inflammatory effects, TestoPrime is the way to go.

However, suppose you are looking for a powerful, targeted solution designed to specifically—and only—boost your T levels, improve your energy, eliminate ED, optimize your workouts, and build muscle quickly, then TestoGen might also be a good option. Overall, all its ingredients boost T levels (or symptoms), synergizing together to provide potent testosterone supercharge. 

Because of it's unmatched customer reviews, power, ingredients, and overall quality, 


Which is the best overall option?

Both products are effective, top-of-the-line testosterone boosters. TestoPrime boasts more ingredients and contains higher concentrations of core ingredients. However, many of its supplementary ingredients do not contribute to T level gains (while still providing many health benefits). Conversely, TestoGen is the more expensive option, providing lower concentrations of core ingredients. However, all the supplementary ingredients contribute to T level gains and synergize with each other for a potent, targeted testosterone boost. Both are great options, but it comes down to what features you value most in a testosterone booster.

Which is safer?

Both contain all-natural ingredients found in food and therefore are extremely safe without any expected side effects. However, those with allergies or sensitivities to any of the ingredients, or those taking higher than the recommended dose, may experience cramps, bloating, and digestive issues. TestoPrime contains more herbal extracts (ashwagandha, Korean ginger) with unknown long-term effects. Thus, this product has more potential to cause minor side effects (headaches, digestive upset) than its competitor.

Which has better value?

Both brands are neck-and-neck for their small (1-month supply) and medium (3-months supply) packages, priced at $59.99 and $119.99, respectively.

Who are TestoPrime and TestoGen Suitable for?

These products are great for any men over the age of 18 who have low T levels or have:

  • Low energy, motivation, fatigue;
  • Low sex drive or erectile dysfunction;
  • Loss of focus, concentration, and mental acuity;
  • Desire to improve muscle-building potential and endurance;
  • Desire to burn stubborn fat deposits.
