Intro: What does TESTOXZEN do?
This is our review of TESTOXZEN, which is a testosterone booster from GX8 Labs.
It has claims to promote:
- Lean Muscle Mass
- Sex Drive
But how well will it work for you?
In this supplement review, we look closer at the ingredients, servings and side effects and see what the science has to say.
This is what we’ve found…
Ingredients: What’s in this testosterone booster?
Quite a lot. Some good, some bad. However, we’re happy to say there’s more good here.
Many of the ingredients in here can help to promote testosterone and have the studies to support them.
Some don’t, and some may even raise estrogen levels.
There’s a lot to get through here, but we’ve covered it as best we can along with our recommendations on how it could all be improved.
Take a look:
We highly recommend Magnesium when building any testosterone boosting stack, and we’re glad to see it here in TESTOXZEN.
So, how exactly does it help you?
The main way Magnesium supports you here is by promoting free testosterone.
Free testosterone is the amount of the male hormone which is available to you and currently circulating in your blood stream.
Magnesium promotes free testosterone by how it interacts with a protein in your blood known as Sex Hormone Binding Globulin (SHBG).
SHBG is a protein that binds to your free testosterone and removes its anabolic potency. This means your testosterone that’s affected stops being effective.
Magnesium helps by binding to the protein and inhibiting it. This reduces SHBG’s overall influence and allows more testosterone to circulate freely throughout your system.
GX8 Labs have made another great choice for their supplement by including Zinc in here.
Zinc is a mineral which doesn’t help with free testosterone, but it can help with general testosterone production.
It does this because your body uses Zinc for specific chemical reactions in your brain. Zinc is key to your body producing the Luteinizing Hormone (LH).
LH is the hormone in your body which is responsible for making testosterone and growth hormone in your testes. It is the precursor for these hormones – and Zinc makes it all possible.
By supplementing Zinc you can make sure that your body has enough of the mineral in your system to make the optimal amount of LH which can give you a big boost in testosterone.
It’s a great addition to this supplement.
Horny Goat Weed
This however, is not as potent in GX8 Labs’ TESTOXZEN.
Horny Goat Weed is a herb which is more commonly known as Epimedium. Some supplement companies claim that it can help promote testosterone levels, however, there’s not much evidence to confirm this.
The only benefit Horny Goat Weed may have for you is a mild boost in sex drive and libido. This is good for your mood, but it won’t do much for your actual testosterone levels.
It’s not the strongest choice in this supplement that we’ve come across.
Again, this isn’t an effective ingredient in TESTOXZEN.
We have to say it: Tribulus Terrestris is a terrible testosterone booster and companies need to stop using it.
There are no studies out there which support it working in isolation to promote testosterone levels in humans.
It’s terrible. Until proven otherwise, Tribulus Terrestris is still the #1 in our list of the worst testosterone booster ingredients.
You can read all that here:
That will cover our views in more detail.
To keep it short here you just need to know that it hasn’t worked effectively for testosterone in any human studies, and at best it is a libido enhancer.
This is a much better option from GX8 Labs. Ashwagandha is a great herb when it comes to helping your testosterone levels.
Because it helps to create a better hormonal environment for your testosterone levels to rise.
Ashwagandha can do this because it can help to lower and regulate your cortisol levels.
Cortisol is your body’s stress hormone, the higher it is the more stressed you are, and also the lower your testosterone.
Due to a hormonal balancing process in your body known as homeostasis, the more you have of one hormone the less you have of another – in this case the more cortisol you have, the less testosterone.
By using Ashwagandha to help keep the balance, the more support your testosterone levels have to grow.
This is a much better addition to TESTOXZEN. Stinging Nettle is an effective choice when it comes to promoting free testosterone levels.
In a similar effort to Magnesium, Stinging Nettle helps to increase free testosterone levels by how it interacts with the protein Sex Hormone Binding Globulin (SHBG) in your blood.
The Beta Sitosterol in the Nettle inhibits the SHGB and reduces its overall impact on the testosterone flowing freely in your system.
This allows you to have more testosterone available for you to use throughout the day.
This is a component that doesn’t have the studies to support it (yet), but research is looking promising.
DIM is a molecule that is commonly found in green vegetables like broccoli and is thought to work as an aromatase inhibitor.
An aromatase inhibitor is essentially an estrogen suppressant. Supplementing one can help reduce your overall levels of the female hormone estrogen which can also help give your testosterone have more of an impact in your system.
Although DIM hasn’t been confirmed to work like this, preliminary research is looking promising.
Time will tell if this will have the clinical backing to work for you.
Pygeum Africanum & Saw Palmetto
These are nutrients that does not boost testsoterone in GX8 Labs’ supplement, but it can help in other ways.
We’ve grouped them together as they both do similar things.
Pygeum is a type of tree bark extract, whereas Saw Palmetto is a berry and both are used as aid to prostate health.
There’s pretty clear evidence that they can help to reduce the overall effects of benign hyperplasia (enlarged prostate).
They’re a good support for male health, but honestly it’s not going to do much for boosting your male hormone.
This isn’t a strong option either for raising testosterone either in this supplement (despite what some may claim).
Avena Sativa is a form of Oat Straw and is thought to help raise testosterone. Unfortunately, there aren’t enough credible studies out there at the moment to confirm it.
We don’t think it’s the best ingredient in here, and you’re unlikely to get much testosterone benefit from it.
This is a riskier choice in TESTOXZEN as the results could go either way.
DHEA is a hormone that your body makes naturally in your body, and is either converted into testosterone or estrogen depending on what your body thinks it needs.
More often than not, it’s likely that your body will use it to balance out whichever hormone is doing better which could lower your testosterone levels if they are already elevated.
It’s also worth noting that some sporting organizations class it as a banned substance. You may not be able to compete with this in your system.
We’re not fans of DHEA, and don’t recommend using considering how it could potentially raise your estrogen levels.
This isn’t a testosterone booster in GX8 Labs’ TESTOXZEN. Bioperine is literally just black pepper.
Although Black Pepper doesn’t help testosterone levels, it can support you in other ways. It promotes nutrient absorption.
This means it can help you to get more out of the other ingredients in this supplement. You’ll absorb more of the other ingredients and they may activate quicker in your system.
Nutrient Profile Overview:
There are lot of ingredients in TESTOXZEN, some are winners, some are losers.
For us, we think the best ingredients are the following:
- Magnesium – Free Testosterone
- Zinc – Testosterone Production
- Ashwagandha – Better Testosterone Environment
- Stinging Nettle – Free Testosterone
- DIM – Potential Estrogen Suppressant
Whereas these are the areas we don’t have as much confidence in:
- Horny Goat Weed
- Tribulus Terrestris
- Avena Sativa
The rest don’t help testosterone, but could benefit you in other ways like with your prostate.
Regardless, we think there’s a lot of room for improvement.
What ingredients would help TESTOXZEN?
D-Aspartic Acid, Vitamin D3, Boron and Fenugreek would all work well here. They all have studies behind them that support them as boosters of testosterone.
These would all work well in this supplement. We’re going to cover them quickly here, but if you want more information on them, definitely check out our page on the testosterone booster ingredients that work, complete with studies and references:
Here’s why they would be a good fit:
This is a nutrient that works in a similar way to Zinc. Supplementing DAA can help promote your overall levels of the Luteinizing Hormone (LH).
As we’ve covered, the more LH you have in your system, the more support your body has to make growth hormone and testosterone.
This is a great addition to any testosterone, mainly because it’s technically a hormone.
Most people don’t get enough D3 throughout the day, as your body naturally absorbs it through your skin via sunlight. With most of us spending the majority of our time indoors, it restricts how much you can get each day.
This is a shame as your testosterone levels and D3 levels are closely linked. By supplementing it, you can help restore balance and give your testosterone levels more of a boost.
Another good mineral that GX8 Labs could use. Boron has numerous studies showing it to help promote testosterone and free testosterone.
What’s more, is there’s also some evidence of it helping to reduce estrogen levels.
It would work really well here.
This is our final recommendation. Fenugreek works in a similar way to Ashwagandha, only Ashwagandha helps regulate your cortisol levels whereas Fenugreek helps regulate your insulin.
Insulin can have the same damage to your testosterone levels as cortisol as they are both governed by homeostasis.
By using something like this to help keep your blood sugar under control, your testosterone levels would have a better environment to rise in.
Safety Check: Could TESTOXZEN cause any side effects?
Nothing serious, but we think you should be wary of the DHEA.
DHEA is banned in some sporting organizations and in some cases it has even been seen to raise estrogen levels.
It’s not something that we would use in a testosterone booster.
If you have any concerns we suggest speaking to your doctor before supplementing this product.
Directions: How are the servings?
There’s only two servings a day. One in the morning, one in the evening.
We’re not sure this is enough.
A typical serving only lasts for a few hours. Meaning this may not be enough to cover you for the whole day.
You should be looking for a testosterone booster that has 3 – 4 servings a day. This gives your body a constant supply of the nutrients you need to keep your testosterone levels on the rise for as long as possible.
It’s unfortunate that GX8 Labs didn’t dose TESTOXZEN this way.
Is this the best Testosterone Booster?
No. There’s better:
We review an endless amount of testosterone boosters every month searching for the most effective one on the market.
We look for supplements that deliver:
- Effective Testosterone Production
- 100% Natural Ingredients
- Increases in Overall Free Testosterone
- Noticeable Strength Boosts
- More Energy
- Enhanced Mood and Sex Drive
- Faster Recovery and Muscle Growth
- Value for Money

Review Summary: Is GX8 Labs TESTOXZEN effective?
We have to say there are some great ingredients in TESTOXZEN, better than many of the other boosters out there on the market.
But it is not perfect. There are still some problems here that we can see. DHEA has the potential to raise estrogen levels, whereas Tribulus, Avena and Epimedium don’t do much at all when it comes to raising the male hormone.
From our review of GX8 Labs’ TESTOXZEN, this is what you need to know:
- Some Ineffective Ingredients – Not all nutrients in here help promote testosterone.
- Potential Estrogen Booster – DHEA could raise levels of the female hormone and is banned in some sports.
- Missing Core Nutrients – Vitamin D3, D-Aspartic Acid, Fenugreek and Boron could all help here.
- Servings could be better – Two a day may not be enough for maximum benefit.
As you can see, this isn’t the best supplement that we would suggest adding to your stack.
