What is TestRX?

According to its official website, TestRX is a bodybuilding supplement, but not in a traditional sense. It does not pump your body with proteins and nutrients in the hope of stimulating muscle growth. 

Instead, TestRX utilizes the muscle-building power of testosterone by increasing your T levels with the help of ingredients like D-Aspartic acid, Vitamin D3, and Zinc. 

Another way TestRX assists men's muscle-building goals is by increasing their energy levels, reducing fatigue, and speeding up post-workout recovery. This allows men to workout harder and more often — resulting in more rapid muscle growth.

Who Should Use TestRX?

In their own words, TestRX is for men of all ages(18+). It offers the same benefits to young adults in their 20s looking to bulk up as it does to older men past their middle ages who want to get back in shape. 

There are several studies that demonstrate the direct correlation between low testosterone levels and declining muscle mass in men. TestRX promises to counteract these symptoms by returning your T levels back to normal with the help of its most abundant ingredient; D-Aspartic acid(DAA). 

This is because D-Aspartic acid supplementation can regulate and boost the secretion of luteinizing hormones. These hormones are a critical component of T production, so an increase in their concentration signals your testes to produce more testosterone. 

The impact of this correlation between DAA and T levels was clearly observed in a 2015 study by J. Bloomer et al. The study showed how regular D-Aspartic acid supplementation can result in a 20% increase in testosterone production for men over the age of 42, after just 28 days.

TestRX Benefits:

While the primary benefit of TestRX is counteracting testosterone deficiency and restoring your T levels, it also offers several secondary benefits. These include:

Increased muscle mass

TestRX increases muscle mass by boosting your T levels since testosterone is the primary muscle-building substance in men. A 1989 study C Griggs et al. tested the impact of testosterone on muscle mass in men and concluded that testosterone increases muscle growth by accelerating muscle protein synthesis.

Improved energy levels

Studies show that men with boosted testosterone levels report higher energy levels by 52.3%. Testosterone deficiency is also linked with lower energy levels and increased fatigue. So, TestRX makes you feel more energetic by returning your T levels back to normal.

Boosted body strength

A 2010 study by Srinivas-Shankar et al. noted down the effects of testosterone treatment in intermediate-frail and frail elderly men. Their testing revealed that almost all test subjects showed significant improvements in their body strength after 6 months. This also applies to younger men where a testosterone boost can allow longer and more intense workouts.

Faster weight loss

There is strong scientific evidence to suggest that low testosterone can lead to faster weight gain and even cause obesity. This works from the other end as well where a healthy boost in T levels can accelerate fat reduction.

Enhanced libido

The relationship between male sex drive and testosterone is quite straightforward. Low testosterone levels can reduce libido and even lead to sexual disorders like infertility and erectile dysfunction. 

Fortunately, using testosterone boosters — like TestRX — can reverse these symptoms by returning your T levels within the normal range.


TestRX’s formula includes seven unique ingredients. Here’s what those ingredients do.

D-Aspartic acid — 2300 mg

D-Aspartic acid has the highest concentration in TestRX and for a good reason. We’ve already discussed how it can boost the secretion of luteinizing hormone and increase T production.

What’s surprising is just how effective it is. A 2009 study by Topo et al. shows how regular DAA intake can increase T levels by 42% in just 12 days. 

Fenugreek extract — 300 mg

Fenugreek has similar T-boosting properties as D-Aspartic acid. Studies show that Fenugreek supplementation for 12 weeks can lead to a 46% increase in T levels. Its use can also improve sex drive, energy, and sperm count.

Vitamin D3 — 1140 IU

Proper Vitamin D levels are essential for maintaining normal T levels and sexual health. A dip in Vitamin D concentration can lead to steadily declining testosterone and libido. Thankfully taking Vitamin D3 supplements can counteract these symptoms completely.

Vitamin B6 — 5 mg

Vitamin B6 doesn’t have any major impact on your testosterone levels. But, its intake can increase energy levels by regulating food metabolism. This increased energy can help you stay more active with more frequent workouts which will, in turn, accelerate your body shape goals.

Zinc — 10 mg

Zinc deficiency is a major cause of testosterone deficiency in men. A 1996 study by S Prasad et al. discovered that a low zinc diet can reduce men’s T levels by a whopping 75% after just 20 weeks. 

Luckily, these symptoms are not permanent and can be reversed with regular Zinc intake.

Magnesium — 200 mg

Magnesium offers several benefits. The most significant of these is the fact that daily Magnesium intake can significantly raise T levels for men who partake in strength training. Magnesium intake is also associated with improved athletic performance as it enhances glucose availability to your muscles.

Vitamin K2 — 20 mcg

Animal studies show that regular Vitamin K2 supplementation for five weeks can lead to a noticeable and consistent increase in T levels. While these studies were performed on rats, researchers believe that K2 has similar benefits for other mammals, including humans.

Additionally, Vitamin K2 intake is also associated with improved cardiovascular health. Though more research is needed on this subject

Additionally, TestRX is one of the more popular testosterone boosters with tons of testimonials mentioning how it actually delivers on its promises.

When And How To Take TestRX?

Are There Any Side Effects?

TestRX reports zero recurring side effects for healthy adults. That said, it does not claim to be 100% safe for everyone because everyone has a unique physiology. 

People with a complicated medical history or an ongoing major illness can experience unintended effects from these supplements. If you fall in this group, consult your doctor before buying TestRX testosterone boosters. 

Also, while allergies to ingredients like Fenugreek or Vitamin K1 are exceptionally rare, they can still be an issue. So make sure you're not allergic to any of TestRX’s ingredients before consumption.
