Their biggest claim is about their key ingredient, D-aspartic acid.
One study claims it can increase testosterone production by 42%.
TestroVax also contains a few different B vitamins and a blend of 13 herbal supplements.
The company claims that these can:
- Increase your natural testosterone levels
- Support muscle mass growth
- Increase energy
- Intensify libido
This supplement may seem like the key to regenerating the testosterone levels you had in your twenties.
But there are some reasons why this may not be the testosterone booster for you.
Let’s dig deeper into the specifics and find out why.
How do you take TestroVax?
Each bottle contains 90 capsules or a month’s supply.
The Novex Biotech website recommends taking 3 capsules per day with breakfast.
The website doesn’t mention needing to cycle off.
How much does this supplement cost?
TestroVax is available at most major online retailers including Amazon.com, GNC, and Bodybuilding.com.
TestroVax is selling for $48.97 on Amazon at the time of writing.
On the company’s website, it’s selling for $69.99.
This price is about in line with most other testosterone boosters.
If anything, it may be a little on the expensive side.
And if you’re going to drop $50 or more on a supplement per month, you want to be sure it’s going to have an effect.
Let’s look at the research to see what you can expect.
The product’s label lists the following dosages per three capsules.
Unfortunately, the dosages in the proprietary blend aren’t broken down.
Without more information, we don’t know how much of each ingredient is in each serving.
Here’s what the research says about each of the main components of this testosterone booster.
- Vitamin B6, Folic Acid, and Vitamin B12: These three B vitamins are critical for maintaining male health. But only Vitamin B6 is to potential boosts in testosterone. One study found that removing vitamin B6 from the diets of rats led to testosterone deficiency (1). So far, no research supports the claim that the supplements increase testosterone levels in humans.
- D-Aspartic Acid: The Novex Biotech website cites a study in which D-aspartic acid increased testosterone production by 42% (2). The study looked at supplementation of 3g per day. Another study found 2.66g of D-aspartic acid per day can increase testosterone production in infertile men by 30-60% over 90 days (3). Each serving of TestroVax only contains 2.7g of the 13 ingredients in their blend. Don’t expect the same level of testosterone boosting effects from a lower dosage of D-aspartic acid.
- Fenugreek Powder: More research than not shows that fenugreek doesn’t affect testosterone production. One study shows that 8 weeks of Fenugreek supplementation improved testosterone production (4).
Other studies in similar settings do not support these findings (5, 6).
- (S)-2-Amino-5-guanidinopentanoic Acid HCl: This ingredient is usually known as L-Arginine. It’s a precursor to nitric oxide (NO), which increases blood flow to the testes. Although research supports L-Arginine’s usage for other parts of male health, there’s no research to back it as a testosterone booster.
- Grape (seed & skin) Extract: Grape seeds and skin are high in antioxidants, which can support your health. Only one study looks at the link between grape seed extract and testosterone. It found no effect in the women who took part(7).
- Minor Ingredients: There needs to be more research on the minor ingredients to see what kind of effect on testosterone they can have. Right now, there’s no research to support their use as testosterone boosters.
The research on the first two ingredients in TestroVax’s blend shows they may improve testosterone levels.
But what are customers saying?
TestroVax has pulled a respectable 8.0/10-star rating on Bodybuilding.com.
It hasn’t scored as well on Amazon.com with an average customer rating of 3.1/5.
This Bodybuilding.com customer reports noticing great results that justify TestroVax’s price.
Since this product is targeting men over 30, it makes sense that many of the people highly rating this product are in their fifties.
Here’s another review from somebody in their fifties who had good luck with this product.
Most of the one or two-star reviews are from customers who haven’t noticed a benefit.
Should You Take this Testosterone Booster?
The following are some of the advantages of this supplement:
- The research on D-aspartic acid is promising
- Novex Biotech’s website states it is targeting men over 30
- It contains over 13 ingredients in its blend
- It’s available from most major online retailers
The following are reasons why you shouldn’t take this supplement:
- The amount of D-aspartic acid in this supplement is low. It is less than the amount used in the research that found it can increase testosterone by 42%
- It’s moderately more expensive than many other testosterone boosters
- Exact dosages of ingredients in the blend aren’t listed
- The filler ingredients may dilute the effects of the research-backed ingredients
TestroVax Bottom Line
TestroVax needs to make a few changes to become one of the top testosterone boosters.
If they included more of their key ingredients and got rid of the filler, it would be a better investment.
If you’re under 30, the company itself says that you shouldn’t waste your money.
This supplement may be an option if you’re over 30 and looking to raise your testosterone back to baseline.
Research on D-aspartic acid looks very promising.
But TestroVax may not contain enough D-aspartic Acid to get the benefits from it.
The biggest complaint we have with this product is that it uses a blend of ingredients.
This means we don’t know how much of each ingredient is in the mix.
Some customers report positive results with TestroVax.
Despite this, but there are better testosterone boosters on the market for the same price.
