Are you a dedicated bodybuilder?
Do you need an edge to build bigger muscles, faster?
The solution may lie in a testosterone supplement1.
TestRx boasts about providing the following benefits:
- Bigger muscles
- More strength
- Athletic potential
- Weight loss
- Faster recovery
We decided to test these claims with a comprehensive review.
Keep reading to see what we discovered.
What Is TestRx?
TestRx is a natural formula created to boost testosterone.
It is sold by a company called Leading Edge Health based in Tennessee.
Below is a list of the main active ingredients in TestRx.
Fenugreek Seed Extract
Fenugreek2 extract included for its ability to reduce body fat.
It is rich in galactomannan, a polysaccharide that triggers fat breakdown and sugar metabolism.
Vitamin D33 is a fat-soluble vitamin that promotes absorption of calcium in the small intestine.
When supplemented at correct levels may boost testosterone by up to 25%.
While this is the conclusion suggested by the evidence, the science is not definitive.
Vitamin K boosts testosterone levels in the testes.
The study used to support this ingredient’s effectiveness was conducted on rats, not humans.
Also, the amount of vitamin K used was far higher than the amount included in this formula.
Vitamin B64 promotes the production of androgens which leads to increased testosterone levels.
Magnesium (as Magnesium Aspartate)
Magnesium5 helps muscle oxygenation and contributes to high physical performance.
Magnesium may help the body use glucose more effectively in response to extreme physical stress as well as increasing strength and testosterone levels.
Zinc (as Zinc Monomethionine)
Zinc6 boosts testosterone and athletic performance.
Studies supporting this conclusion used zinc in higher quantities before clinical effectiveness was observed.
D-Aspartic Acid7 is an amino acid that supports sperm cell and testosterone production.
It can also lead to increases in virility.
While clinically effective amounts range from 2000mg to 3000mg and the ingredient label on TestRx claims to provide 2300mg, the website lists the amount provided as 575mg.
How Does TestRx Work
According to their website:
TestRx ingredients promote testosterone production which increases the rate of protein synthesis. This facilitates the building of muscle mass and inhibits the hormone cortisol, which breaks down muscle tissue.
Testosterone helps with protein synthesis by binding to androgen receptors in muscle cells. The body uses that protein to repair the tiny micro-tears that occur in your tissue after you lift weights and build muscle as a result.
More testosterone means more growth, faster recovery and bigger muscles. It also increases the red blood cells in your body and helps with better oxygen flow.
How To Use It?
TestRx comes in capsule form.
Two capsules should be taken daily, preferably one in the morning and one in the evening.
TestRx Side Effects
Possible side effects include bloating, gas, abdominal discomfort, upset stomach, diarrhea, and lowered blood sugar levels.
Although none of these have been reported in the reviews and even if they do occur they are not generally considered serious.
Is It A Scam?
The ingredients in TestRx are all familiar, natural products whose effects have been well researched.
Most of the ingredients have been found effective in increasing testosterone levels.
It should be noted that much of the science is suggestive rather than definitive.
Another issue is the potential confusion when purchasing the product.
There are 2 different products with 2 completely different formulations from the same company.
The current version contains ZMA (Zinc, magnesium and vitamin B6) and Fenugreek.
The old version contained Ashtanga, Tongkat Ali and cabbage seed extract.
ZMA is a combination of zinc, magnesium and D Aspartic Acid, which many athletes and bodybuilders are using to increase testosterone.
It is difficult to distinguish between the two supplements as they both carry the same name and the packaging is the same.
The most recent version of TestRx comes in packs of 120 capsules while the previous version was packaged in boxes of 60.
There is also another product on the market from a different company with a different formulation called Test-Rx, with a hyphen.
It is important to pay close attention to ensure you have selected the correct product.
TestRx Reviews & Complaints
TestRx has been on the market for a few years but there are relatively few independent reviews.
Here are some that may prove useful.

Before taking this testosterone booster I used to feel drained of energy soon after 1 PM and I was also feeling angry a lot of the time.
1 week after taking this I started feeling refreshed and I’m now almost never drained, at least, not until 7 – 8PM which is a huge jump forward.
I also feel calm most of the time and can’t find as many reasoned to get angry about. My wife has especially noticed this and congratulated me on not consuming my energy on pointless things.
Jerry of Fitnessreport.com wrote:
My mood has improved, I can bench press a bit more now, I have a bigger sex drive (which believe it or not was very low for me) and the most important thing of all; I don’t feel the need for my second cup of coffee. I just have plenty of energy now and don’t require drinking as much coffee as before.
Thomas of Fitnessreport.com wrote:
Very happy with the overall improvements I am seeing after only 10 days of TestRx. I’ve been thinking of getting a testosterone booster for some time and I’m glad I choose this one. Better mood, better sex, higher energy levels.

Pros & Cons
TestRx Review: Final Words
TestRx is formulated with many familiar ingredients backed by some evidence-based science.
The amounts of some ingredients used are not enough to be clinically effective.
Although the product has been around for some time, there are few customer reviews available.
The reviews that are available are generally positive but are in no way verifiable and may not be independent.
The ingredients can be obtained elsewhere for much less.
There is nothing proprietary about the product.
