Summary: Testro-X is manufactured by Truth Nutraceuticals. For my review I dug out all the applicable research on each one of Testro-X's ingredients and its interaction with testosterone. Based on my analysis of the research, supplementing with Testro-X can have a positive influence on your testosterone levels. 

Verdict: Recommended (but there are better supplements out there)

DOES TESTRO-X WORK?

Compared to some other test boosters that I've reviewed, Testro-X is definitely a level above. Most of its ingredients are backed by research and proven to have a positive influence on testosterone. So, yes Testro-X works.

But:

I encourage you not to rely on it as the sole means towards helping you achieve higher testosterone levels. Like I say in all of my reviews:

Supplements should only be used for what they're made, i.e. to supplement your diet and lifestyle.

There's no such thing as a magic-pill and you should only consider investing in Testro-X after getting your your diet, training, sleep, and other lifestyle factors aligned with the goal of achieving hormonal balance. The priority should always be diet and lifestyle, after which you can start using supplements to help see results faster. 

TESTRO-X DETAILED REVIEW

​Truth Nutraceuticals was founded by two men that I really look up to: Christopher Walker and Ali Kuoppala. Both of them have had a tremendous impact on my life, not only as mentors that helped me get my hormonal health handled, but also as inspirations to start my own Men's Health Website. 

With that being said, I've done my best to remain unbiased and to provide you with only the information you need to make an informed decision before purchase.

Testro-X Ingredients: 4/5

Testro-X contains no proprietary blends and all the ingredients are laid out as is. 

Testro X Ingredients

Magnesium

Magnesium is an essential mineral that we need to fulfill a number of bodily processes. Some benefits that come with maintaining magnesium balance include increased energy, calm nerves, better sleep, a healthy heart, and stronger bones. Turns out,  magnesium levels are also directly correlated with testosterone. Here's a quick look at the research: 

  • ​After analyzing the blood work of 399 men over the age of 65, researchers found magnesium levels to be strongly and independently associated with total testosterone levels (1). 
  • Athletes and sedentary subjects were given 10mg of magnesium per kg of bodyweight for 4 weeks, after which both groups experienced significantly higher testosterone levels. The increase was more significant, though, in the athletic group (2). 

Magnesium deficiency is amongst the most prevalent micronutrient deficiencies in developed countries (second only to vitamin D). An estimated 48% of American adults get below the recommended amount of magnesium through their diet (3). 

The fact that Testro-X includes magnesium in its formula definitely is a plus point. But keep in mind that topping up your magnesium levels will only impact your T-levels to the extent that you are currently deficient in it. If you're already getting enough magnesium through the foods you eat, then increasing your levels even further will not increase testosterone.

Zinc

Zinc is actually a type of metal. It is required by our body in trace amounts, and is involved in a number of functions ranging from hormone production to facilitating growth and development. Getting enough zinc is associated with increased immunity, balanced hormones, a healthy heart, improved digestion, and a reduced chance of developing type 2 diabetes. 

 Here's a quick look at the research on zinc and its interaction with testosterone: 

  • Researchers found that extreme exercise led to a significant decrease in testosterone levels. This decrease, however, was prevented in elite wrestlers supplementing with zinc (4). The same effect occured in subjects exercising on a sedentary bike (5). 
  • In male patients undergoing kidney dialysis with an apparent zinc deficiency, 250mg of zinc supplementation for 6 weeks was associated with significantly higher testosterone levels (6). 
  • In infertile men with testosterone levels below a certain threshold, zinc supplementation was able to significantly increase their testosterone levels (7).

Zinc impacts testosterone to the same degree as magnesium. If you're deficient in it, then topping up your levels can help bring your T closer to where it should be. If you already have an optimal balance, then zinc supplementation will do next to nothing for your T. 

Testro-X provides 100% of your daily zinc requirements.

KSM-66 Organic Ashwagandha Root Extract

​Ashwagandha (Withania somnifera) is a herb from India that has traditionally been used to strengthen the immune system after illness. The word Ashwagandha means "strength of stallion" implying that the ingestion of this herb provides the strength and virility of a horse. 

Ashwagandha is termed an adaptogen for its ability to alleviate the physical and chemical effects of stress. Other benefits of ashwagandha include improved cognitive function, better mood, and increased stamina and endurance. 

Let's take a look at the research behind Ashwagandha and its interaction with testosterone: 

  • In subjects with chronic stress, 60 days of supplementing with 300mg of ashwagandha was able to lower cortisol levels by 27.9% (8). 
  • Infertile men supplementing with 5g of ashwagandha for 3 months experienced an increase in testosterone (10-22%) and a decrease in cortisol (11-32%) (9). 
  • Chronically stressed subjects supplementing with ashwagandha for 60 days saw significant decreases in cortisol pretty much in a dose-dependent manner (14.5% for 125mg/day, 24.2% for 250mg/day, and 30.5% for 500mg/day) (10). 
  • Untrained men put on an 8-week periodized strength training program were given either 300mg of ashwagandha or placebo. At the end of the study, the ashwagandha group had significantly higher testosterone levels. They also experienced greater increases in strength (20kg stronger 1RM on bench press compared to placebo) (11). 

Ashwagandha is very well-researched and its results have been repeated in multiple human studies. It is amongst my favorite testosterone booster ingredient, simply because its proven to work.

The fact that ashwagandha is Testro-X's primary ingredient is what sets it apart from some other test booster supplements that I've reviewed in the past.

Forskohlii Root Extract

Coleus forskohlii is a herb from India that has traditionally been used to treat heart, lung, and skin conditions. The active ingredient in coleus forskohlii is forskolin, which today is widely used for its apparent ability to induce fat-loss. As per its interaction with testosterone, let's take a look at the lone human study: 

  • Overweight men supplementing with 250mg of a 10% forskolin extract two times a day for 12-weeks had significantly higher testosterone levels compared to placebo (12). 

Although this study has shown forskolin have a positive interaction with testosterone, further research is needed to confirm this.

Inositol

Inositol is a chemical compound that is structurally similar to glucose. It's commonly given to women with polycystic ovarian syndrome (PCOS) to increase ovulation and fertility rates. 

On TruthNutra's website they say that inositol was included in the Testro-X formulation to enhance GnRH production (GnRH is a precursor for testosterone). They cite this study to back up that claim. The study, however, was performed using the cloned cDNA of a sea lamprey, so there's no evidence that the same effect carries on to effect humans as well. 

(source)​

Glycine

Glycine is an amino acid that is essential for many muscle, metabolic, and cognitive functions. Its primary function is energy regulation, i.e. it breaks down and transports nutrients to be used by cells. 

On TruthNutra's website they say that Glycine was also included in the mix (like inositol) to enhance GnRH production. And again the study they cite to back up this up is extremely complicated and involves a female infant and rats. 

(source)

L-Theanine

Theanine is an amino acid that is known to promote relaxation without sedation. It is also effective at combating stress and anxiety. 

The only dietary source of theanine is teas made from Camellia sinensis (green and black tea). 

I was unable to find any research demonstrating the interaction between Theanine and hormones, but on TruthNutra's website they cite this study to back up the claim that it enhances GnRH. Honestly, that study was far too complicated for me to understand (and I think it was performed in a test-tube). 

(source)

Boron

Boron is an important mineral that is naturally present in some foods and in the environment as well. Some benefits of boron include stronger bones as well as improved muscle and strength. As per its interaction with testosterone, let's see what the research says: 

  • Healthy male adults supplementing with 10mg of boron experienced 28% higher free testosterone levels and 39% lower estrogen levels after just 7 days of use (14).
  • Athletic males supplementing with 2.5mg of Boron for 9 weeks while lifting weights experienced no differences in testosterone levels compared to placebo (15). 

The above are the only two human studies I was able to find on how boron affects testosterone. There are rat studies (16, 17) that show a significant positive correlation, but I don't like using those as a reference because it's not sure that the same effects carry on to humans as well. 

As of now, the research regarding boron is mixed. A point to note, however, is that the dose used in the first study was 4 times higher than the dose used in the second study.

Boron definitely seems to be one of the more promising ingredients added to testosterone supplements, and the fact that Testro-X provides 10 mg of it may have a significant positive influence on free testosterone levels.

Bioperine

Bioperine is a patented extract obtained from black pepper. It has no individual benefits, but is readily added to dietary supplements to increase the absorption rate of some of the other active ingredients.

HOW DOES IT COMPARE?

Testro-X is definitely one of the better testosterone booster supplements I've come across. Some of the best-selling supplements on the market contain ingredients that are proven not to work. This is not the case with Testro-X.

For this portion of the review, let's see how Testro-X stacks up against some other popular supplements. 

Testro-X vs Prime Male

Prime Male is another one of the better dosed testosterone supplements out there. It contains no proprietary blends and is packed full of vitamins and minerals that are proven to have a positive influence on testosterone. 

That being said, the primary ingredient in Prime Male is D-Aspartic Acid. D-AA has a lot of mixed research behind its interaction with T. Ashwagandha, the primary ingredient in Testro-X, has a ton of research backing up its benefits. 

As far as the micronutrient profile is concerned, I'd say Prime Male takes it since it has the addition of 5000IU of vitamin D. But since vitamin D is readily available and cheap to purchase, I'd recommend Testro-X over Prime Male. 

Winner: Testro-X

Testro-X vs Status

Status is a testosterone booster manufactured by Blue Star Nutraceuticals. 

Like with Testro-X, Status also has Ashwagandha as its primary ingredient. The dosage in Status, however, is 50% higher. 

Testro-X contains boron and Status contains Tongkat Ali, both ingredients that have the potential to be powerful testosterone boosters. 

Both these supplements are definitely in the upper echelon of the many test boosters I've ​reviewed, but since Status has a higher dose of Ashwagandha, I'd say that it takes the cake. 

Winner: Status

Testro-X vs Nugenix

Nugenix is another very popular testosterone booster supplement. The primary ingredients in it are comprised within a proprietary blend, so we can't be sure of the dosages. Either way, L-Citrulline, Fenugreek, and Tribulus make up the bulk of its formulation. 

Out of these 3 ingredients L-Citrulline has been shown to enhance nitric oxide levels, fenugreek has mixed research on its interaction with testosterone, and tribulus is an ingredient that has been proven not to work. 

Nugenix is not a supplement that I recommend.

Winner: Testro-X

Testro-X vs Testofuel

Testofuel is another very popular hormonal support supplement. Its primary ingredients are D-AA, ginseng, fenugreek, and oyster extract. 

None of these ingredients have definitive evidence supporting a positive influence on testosterone levels. Oyster extract can help you increase zinc levels, but if you're already getting enough zinc through diet, then additional amounts will not increase T further. 

Testofuel also contains a proven micronutrient formula, with zinc, magnesium, and vitamin D in the mix. But since the main ingredients have not been proven to impact T, I don't recommend it. 

Winner: Testro-X
