Low testosterone levels have a disappointing effect on your quality of life. TestroVax wants to help you correct this problem by raising your testosterone levels 42% in 12 days.

TestroVax is a new dietary supplement from Novex Biotech. According to advertisements, TestroVax is a clinically-tested and proven testosterone booster for men over 30. With healthy testosterone levels, Testrovax promises muscle mass growth, increased energy, and intensified libido.

Novex Biotech insists again and again that TestroVax is a powerful over-the-counter supplement, and I wanted to see if these claims were warranted. To do that, I’ll consider Testrovax manufacturers, formula, customer response, and pricing.

Who Makes TestroVax?

Because TestroVax is a new product, we should start by considering the TestroVax manufacturers. In this case, that’s Novex Biotech.

Novex Biotech is a company based in Salt Lake City, Utah that develops workout supplements. Unfortunately, Novex Biotech doesn’t provide any information about the company on its website. By researching the physical address and other contact information, however, I was able to link the company to Basic Research, LLC.

Basic Research has an impressive A+ rating with the Better Business Bureau, something I don’t often see when researching supplement companies. There’s only 1 complaint on file for the past 3 years, which Basic Research has since settled.

Basic Research has been in business since 1992, which tells me that the company is well-established and successful enough to stick around. This gives TestroVax some serious points in its favor already.

What Ingredients Are in TestroVax?

TestroVax uses a 2.7-gram proprietary blend called TestPRO to raise testosterone levels. This blend contains 12 natural ingredients, including amino acids and herbal extracts.

Generally, I don’t like proprietary blends because they don’t tell us anything about individual ingredient amounts. This makes it difficult to judge effectiveness. However, the TestPRO blend is a large one, so there’s a chance each ingredient could be included in its recommended amount.

For now, I’ll settle for analyzing each ingredient in the TestPRO blend.

Schizonepeta Powder

Schizonepeta powder is an herbal extract mostly used for skin problems like eczema. It also reduces fever and sore throat. However, there is no evidence or even anecdotal claims that schizonepeta raises testosterone levels. For that reason, I don’t know what it’s doing in TestroVax.

D-Asparaginic Acid

D-Asparaginic acid, or d-aspartate, is an amino acid produced in the pituitary gland. It stimulates production of luteinizing hormone (LH), which boosts testosterone production in the testicles. In one study, men taking d-aspartate saw their testosterone levels increase by more than 40% in 12 days [1]. It’s likely this study that Novex Biotech references in their advertisements.


Fenugreek is well-known for treating erectile dysfunction, so it makes sense that it would raise testosterone levels. Unfortunately, there is no conclusive evidence that fenugreek boosts testosterone production. In fact, a 2009 study found no change in the hormonal profile of study participants taking fenugreek [2].

1-2-Amino-5-Guanidinopentanoic Acid HCI

You probably know this ingredient as arginine. Another amino acid, arginine stimulates nitric oxide (NO) production [3]. NO widens blood vessels to increase nutrient flow throughout the body. With better circulation, more testosterone travels through the body.


A chemical found in red wine, resveratrol is an antioxidant that works much like nitric oxide. Resveratrol expands blood vessels to increase circulating testosterone levels. It also decreases pain and swelling related to inflammation, and decreases estrogen production.

Grape Seed and Skin

Both grape seed and grape skin extract have testosterone-boosting effects. Studies show grape increases blood testosterone levels, along with other measures like sperm count [4].However, much of the research has been done on rats, and those benefits don’t always translate to humans.

Rhodiola Rosea

Rhodiola is a so-called “adaptogen,” which means it improves the body’s response to physical and environmental stress. That makes it great for improving athletic performance and sexual function. It is thought to work by protecting cells from damage and regulating heartbeat. However, it has never been tested in humans.


I’m not sure why licorice is included in TestroVax, since it actually decreases testosterone levels. This was proven in several studies, including a 2003 study where testosterone decreased testosterone by 25% in a week [5].

Red Clover

The tops of red clover contain “isoflavones,” which convert to “phytoestrogens.” Phytoestrogens act similarly to the hormone estrogen, so I’m not sure why red clover is included in TestroVax.


Damiana is an herbal extract most commonly used as an aphrodisiac. By stimulating greater testosterone production, damiana stimulates the brain and nervous system to increase sexual desire.

Withania Somnifera

This ingredient is better known as Indian ginseng. Ginseng improves energy and athletic performance by lowering blood sugar. There are many claims that ginseng raises testosterone levels, but this effect has only been demonstrated in rats [6].

2-Aminoethanesulfonic Acid

This amino acid is better known as taurine. Taurine is a powerful antioxidant, which improves mental and physical performance. It also treats congestive heart failure and high blood pressure. Some anecdotal evidence suggests it increases testosterone production, but it hasn’t been tested.

For the most part, TestroVax seems to include good ingredients. There are 2 or 3 that make me raise my eyebrows, but together, I think they’ll get the job done. However, I’m not sure that TestroVax is as powerful as it claims.

What Do Customers Think of TestroVax?

TestroVax is still a new product, so customer reviews are pretty scarce. However, those that do exist are positive. Customers cite signs of increased testosterone in gains at the gym and performance in the bedroom.

Other Novex Biotech products have garnered positive reviews. Every product on Amazon.com has a 3.5/5-5/5 star rating, which is impressive for a supplement company.

However, you may want to wait until more customer reviews come out to see if TestroVax is as well received as its Novex Biotech brethren.

Is TestroVax Expensive?

One downside to TestroVax is the price tag. On NovexBiotech.com, TestroVax retails for $69.99 a bottle. This is quite a bit more expensive than the average testosterone booster. However, if TestroVax works as it says, it may be worth it.

You have the opportunity to get 20% off by signing up for a monthly TestroVax subscription. This subscription decreases the price to $55.99 and qualifies you for free shipping. However, you shouldn’t sign up for a subscription until you know that TestroVax works for you.

Fortunately, GNC.com offers TestroVax for a discounted rate. There, you can get the same month’s supply for $49.99. This is more manageable, but still more expensive than the average T-booster.

Should You Try TestroVax?

If you can afford it, TestroVax seems like a good choice. It has quality ingredients, a reliable manufacturer, and a solid clinical study to support it. However, without more customer feedback, you can’t be sure.

There are plenty of more affordable options with a wider degree of customer feedback. You can go with one of these, or wait a little longer to see how TestroVax fares on review sites like GNC or Amazon.

Bought a bottle and started with a lower dose, one pill per day just to see if there was any reactions…upped the dose to 2 pills per day and noticed a huge boost in energy from day to day. Labido did go thru the roof, no joke! Stayed at 2 pill per day until bottle was gone…I’m 42 yrs old and def felt that this product did what is was supposed to do. I have had no reactions or rage issues. Next bottle I will go to 1 pill in the morning and 1 late day. I think most reviews that are negative on this product are because the people using it have proper test levels to begin with

Yes, I recommend this product

Well… I’ll start by saying I had some hopes as I am about to turn 60. Ive been working out my whole life it seems though I am down to 4 workouts per week. 1 hour to 1 hour 15 minutes max. Push – pull so every muscle group is getting adequate recovery time. I’m pretty strong and have decent muscle mass, so because of my age I figured why not…lets see if this can help tip me over the edge again and out of the plateaus…
Nope…. I feel absolutley nothing after 30 days and per their GTD I’ll be requesting a refund! This is laughable and I should have known better, especially with their “not for everyone claim”…. That’s nothing more than their pre-built in excuse. This product is an absolute waste of money and I am one of the pefect candidates for a test. What a farce!

No, I do not recommend this product

I have personally been using TestroVax for two months now and there is no question that with a proper diet and serious lifting, this stuff works. It took a good month to feel and see results, but without a doubt I am completely happy with this product.By the way I am over fifty years old and am in the best shape in 25 years.

Yes, I recommend this product
