What it offers

The main purpose of this supplement is to regulate testosterone levels and counteract age-related T deficiency. But, the proposed benefits of Testogen are a lot broader and help improve your overall mood, energy, and libido. 

In their own words, taking Testogen will help you get in better shape faster by increasing your muscle strength and eliminating fatigue. It also claims to assist your weight loss efforts by accelerating fat oxidation.

Ingredients behind these claims

Testogen enlists the help of 11 unique ingredients to back the claims and proposed benefits of their T-boosting supplements. Two of the most notable ingredients in this list are D-Aspartic acid and Fenugreek extract, both of which are well-known for their testosterone-boosting abilities. 


  • Claims to be vegan with a vegetable-based capsule enclosure.
  • Improves libido and sexual performance.
  • Counteracts age-related low testosterone.
  • Boosts energy levels and reduces fatigue.


  • Requires you to take four capsules every day.

What is TestRX?

The primary goal of TestRX is summarized by the following statement on its official website's homepage: 

"Stack on Pounds of Lean, Hard Muscle at Any Age." 

But, unlike anabolic steroids that offer similar benefits, TestRX claims to be a completely natural supplement.

How it works

While TestRX positions itself as an effective supplement for bulking up, it actually works by regulating your testosterone levels. Its proposed benefits, like accelerated muscle growth, increased workout performance, reduced excess fat, and improved libido, are the results of your T levels returning to normal. 


The most abundant ingredients in TestRX's formula are the common testosterone-boosting substances; D-Aspartic acid and fenugreek extract. It also includes a notable dose of Magnesium, which offers several key benefits, from higher testosterone availability to improved sleep.


  • Can help you cut down excess fat.
  • Reduces fatigue to allow longer workout sessions.
  • Brings T levels back to normal.
  • Manufactured at a cGMP-compliant facility in the USA.


  • Not vegan or vegetarian-friendly.

Shared ingredients

The six common ingredients between Testogen and TestRX include the following:

D-Aspartic acid

D-Aspartic acid is one of the most prominent testosterone booster ingredients as it boosts the secretion of luteinizing hormone (LH). This increased concentration of LH signals your testes to produce more testosterone, which can result in a 42% increase in T levels in just 12 days.

Fenugreek extract

Fenugreek extract has similar testosterone-boosting abilities as D-Aspartic acid. A 2017 study by Maheshwari et al. shows that continuous Fenugreek intake for 12 weeks can result in a 46% increase in testosterone production.


Studies show that Zinc deficiency can decrease testosterone levels by a whopping 75% in 20 weeks. Fortunately, zinc supplementation can counteract these effects and bring T levels back to normal.


A 2015 study tested Magnesium and testosterone concentration in 399 men over the age of 65 and discovered that men with higher Magnesium levels also had higher T levels. Research also suggests that taking Magnesium supplements could increase serum testosterone concentration.

Vitamin B6

Vitamin B6 intake can increase your energy levels by regulating food metabolism. These boosted energy levels can help you stay active, allowing you to do more exercise with longer workout sessions.

Vitamin D3

Dietary intake of Vitamin D3 through supplements increases Vitamin D status, which in turn increases free testosterone levels.

Testogen unique ingredients

Out of Testogen's 11 ingredients, five are not present in TestRX. These include:

  • Korean Red Ginseng extract

    Ginseng has been used in traditional medicine and as an aphrodisiac for centuries. Today, its inclusion in testosterone-boosting supplements can help boost your libido and sexual function. Studies also demonstrate its use as a possible treatment for erectile dysfunction.

  • Boron

    Boron can increase testosterone levels after just seven days of use. This is because it decreases the concentration of sex hormone-binding globulin, a protein that binds to testosterone and lowers its availability.

  • Nettle Leaf extract

    Nettle leaf extract offers similar benefits to Boron. It contains a compound called Lignan, which binds to sex hormone-binding globulin proteins and prevents them from lowering serum testosterone concentration.

  • Vitamin K1

    A 2019 study with about 4375 participants showed that folks with higher Vitamin K1 intake have a lower risk of developing depressive symptoms.

  • Piperine

    Piperine does not offer any direct benefits of its own. But its inclusion in Testogen's formula can increase the bioavailability of other ingredients by more than 30%. (Bioavailability is the degree to which a substance, such as a drug or nutrient, is able to enter the body and have an active effect.)

TestRX unique ingredients list

TestRX only has one unique ingredient compared to Testogen, which is:

  • Vitamin K2

    A 2011 study by Ito et al. noted the effects of Vitamin K2 supplementation on rats. After five weeks of testing, most subjects showed a noticeable and consistent increase in testosterone production. While this was primarily an animal study, researchers believe that Vitamin K2 can have similar effects on other mammals — including humans.

    Some studies also attribute regular dietary Vitamin K2 intake to reduced risk of heart disease. Though, more research is needed on this subject.

Side effects

Testogen and TestRX claim to have fully natural compositions with reportedly zero side effects. But this does not mean that these supplements are safe for everyone. 

Every person has a different physiology, and although rare, allergies and high sensitivities to ingredients like Ginseng and Fenugreek can still be an issue for some. So, make sure to read the complete list of ingredients to avoid such problems. 

It is also important to note that you should consult a doctor before considering testosterone boosters if you're pregnant or have a major illness.
