As a man, nearly every adverse effect of aging can be traced back to the decline in testosterone production. With less testosterone, you may feel your masculinity has dropped with it. TestroVax wants to help you get it back.

TestroVax is a new T-booster from Novex Biotech, a long-standing supplement company based in Salt Lake City. Novex Biotech’s good reputation first made me curious about TestroVax, and its confident advertising claims heightened my interest.

To find out if TestroVax really lived up to this hype, I investigated a little further.

What Does TestroVax Do?

TestroVax proposes to increase testosterone production by 42% in 12 days. But what does more testosterone really do?

If TestroVax works as advertised, you should see:

• Increased muscle mass growth
• Higher energy levels
• More sex drive and better performance

Testosterone also fuels your workout, helping you to shed fat and gain muscle. This means a healthier body composition and better athletic performance.

The trick, of course, is for TestroVax to effectively increase testosterone production. To determine that, we’ll need to look at the TestroVax formula.

What Ingredients Are in TestroVax?

TestroVax contains vitamins B6 and B12, folic acid, and a 12-ingredient proprietary blend called TestPRO. Because TestPRO is responsible for TestroVax’s testosterone-boosting properties, those are the ingredients I’ll be focusing on.

TestPRO is a 2.7-gram proprietary blend, which makes it a larger dose than those included in many proprietary blends. Because most proprietary blends suffer from small quantities and too many ingredients, this is a good sign.
The ingredients in TestPRO include:

Schizonepeta Powder

Schizonepeta is an herbal extract commonly used to treat skin problems and sore throat. There is no evidence, or even anecdotal claims that schizonepeta improves testosterone production.

D-Asparaginic Acid

This ingredient is better known as aspartic acid. Aspartic acid is an amino acid produced by the pituitary gland, responsible for increase production of luteinizing hormone (LH). LH boosts testosterone production in the testicles by more than 40% [1]. This is the study Novex Biotech cites in their advertisements.


A common erectile dysfunction treatment, fenugreek seems as if it would increase testosterone production as well. However, that’s not quite the case. Fenugreek has never been shown to increase T-levels. In fact, a 2009 study showed no measurable differences in the hormonal profiles of those who took fenugreek and those who did not [2].

1-2-Amino-5-Guanidinopentanoic Acid HCI

Better known as arginine, this ingredient is an amino acid that stimulates nitric oxide production [3]. Nitric oxide widens blood vessels, increases nutrient flow, and improves circulation. This ensures you get more testosterone where you need it.


Resveratrol is an antioxidant found in red wine that works much like nitric oxide. Resveratrol expands blood vessels, increases circulating testosterone levels, and decreases pain and swelling. It also decreases estrogen production, which maximizes testosterone’s effectiveness.

Grape Seed and Skin

Grape seed and grape skin work much like resveratrol. With testosterone-boosting effects, grape extract increases blood testosterone levels and sperm count [4]. However, these benefits have only been demonstrated in rats so far.

Rhodiola Rosea

As a so-called “adaptogen,” rhodiola improves your response to physical, emotional, and environmental stress. This means you’ll see benefits both in athletic performance and sexual function. However, these benefits have never been tested in humans.


Licorice is actually used to decrease testosterone levels, so I can’t see why Novex Biotech chose to put it in TestroVax. In fact, subjects in a 2003 study who took licorice saw their testosterone levels decrease by 25% in just a week [5].

Red Clover

Red clover contains isoflavones, which convert to phytoestrogens. Because estrogen is the last thing you’d want in any T-booster, I don’t understand why it’s included in TestroVax.


An herbal extract used as an aphrodisiac, damiana stimulates greater testosterone production and triggers action in the brain and nervous system. This increases sexual desire.

Indian Ginseng

Listed as withania somnifera, Indian ginseng is a powerful addition to any workout supplement. It raises energy and athletic performance by controlling insulin and blood sugar. Rats taking ginseng have seen their testosterone levels rise, but these benefits have not yet been tested in humans [6].


Rounding out the formula is taurine, another amino acid. Taurine is a powerful antioxidant, which means it keeps disease at bay, including heart failure and high blood pressure. Anecdotal evidence suggests it increases testosterone production, but these benefits aren’t proven scientifically.

With the exception of licorice, red clover, schizonepeta, and fenugreek, these seem to be quality ingredients. And considering the large proprietary blend, there’s a good chance each is included in its appropriate, recommended amount.

However, we can never be sure this is the case. And without customer reviews readily available, we can’t judge from others’ experience. That’s one downside of a brand-new product.

Can TestroVax Cause Side Effects?

Most testosterone boosters aren’t too strong, which means you won’t see the mood issues and hair loss you would with testosterone injections. However, individual ingredients in T-boosters can cause side effects.

For example, the amino acids in TestroVax sometimes cause bloating and abdominal discomfort. Other herbal ingredients can cause rash-like reactions.

The key to avoiding these side effects is to follow the manufacturer’s usage instructions and drink plenty of water. Also, avoid taking TestroVax over long periods of time. If you intend to use TestroVax for more than one month, take a week off between cycles.

What’s the Best Deal on TestroVax?

TestroVax is a new product, so availability is still limited. You can find it on NovexBiotech.com for $69.99 a bottle, which is pretty expensive for a T-booster. However, you can take the price down to $55.99 if you agree to sign up for monthly shipments.

This seems like a decent idea, but you probably won’t want to use TestroVax for more than 3 or 4 months at a time. Will that be worth the hassle of calling and canceling your shipment? That’s up to you to decide.

Another option for saving money is buying TestroVax for $49.99 on GNC.com. This is a more manageable price, but is still more expensive than the average testosterone booster. Perhaps as TestroVax grows more popular, availability will open up on venues like Amazon and eBay.

Is TestroVax Worth a Try?

TestroVax seems like a quality supplement from a solid company, but with such a high price and such a new status, I can’t quite recommend it yet. It’s possible that TestroVax will turn out to be a successful product. However, until we know more about customer response, spending $60 on TestroVax seems like an unnecessary gamble.
