Superset Nutrition XenaTest Hardcore Review


We’re looking at one of the most popular testosterone boosters in France here – XenaTest Hardcore. Although it’s not as popular in the USA, it’ll be interesting to see whether this product can make it into our top three test boosters list this year.

Claimed to promote:

  • Testosterone levels
  • Muscle growth

After taking a quick look at the ingredient list, we’re glad to see that there’s no proprietary blends in this testosterone booster. However we’ve also realized that some ingredients have been underdosed (we’ll explain this in more detail later in this review).

About The Company

We’re guessing that this company is French, however, we can’t say for sure as their ‘about us’ section was empty on their website. We won’t lie; we hadn’t heard of this company before this product, so we only know as much as you at this point…

But fortunately, we know a thing or two about nutrients and ingredients inside these supplements. So let’s see what Superset Nutrition has added into XenaTest Hardcore…

The Ingredients and How They Work

In terms of ingredients, XenaTest Hardcore doesn’t contain an overload of nutrients, which is great. However, even looking the ingredient list quickly, we can see that key test booting ingredients are have been left out of XenaTest Hardcore.

The only proven nutrient inside XenaTest Hardcore is vitamin d3 and d-aspartic acid, and from first glance, they both seem very underdosed anyway.

See for yourself:


D-Aspartic Acid 

You might have seen this on the ingredient list of other supplements as ‘DAA’, which is the shorter name for it. In a nutshell, DAA helps to regulate testosterone in your body, so it only makes sense that it’s able to encourage your body to produce more of this hormone.

There’s been numerous studies that prove DAA boosts your test levels, but they show that this nutrient is only effective in dosages between 2,000-3,000mg. If you look at the ingredient list for XenaTest Hardcore, then you’ll see that Superset Nutrition has only added 1,500mg DAA into their testosterone booster supplement (meaning it’s been underdosed).

As a result, there’s a chance that DAA won’t have any effect on your test levels – making it a potentially ineffective ingredient. It’s a shame, as DAA is a key T-Boosting nutrient when dosed optimally, but this shows how important it is for companies to dose their products correctly.


This compound is known for being in red wine, and is the reason why the myth that red wine can expand your lifespan exists. Yes, it was originally believed that resveratrol prolonged your life.

However, since then, studies have shown that resveratrol isn’t some-kind of miracle ‘fountain of youth’ ingredient. Not only that, it hasn’t shown to improve your testosterone levels either – making it an ineffective addition to XenaTest Hardcore.

In a nutshell, resveratrol might be able to slightly improve your general health, but it won’t boost your T levels.

Coleus Forskohlii 

We’d be lying if we said we knew every single detail about this herb. It’s a relatively new ingredient that’s thought to be able to improve your test levels and promote fat loss…and if it’s proven to work, then it’ll be a perfect ingredient in the supplements industry.

However, as you know, there’s no such thing as perfect – there’s drawbacks to almost everything. And if we’re being honest, coleus forskohlii sounds too good to be true at the moment.

We believe that studies will find that coleus forskohlii will be effective at delivering 1 benefit (either promoting fat loss test levels, not both). But until then, we’re not sure whether this is better suited to a testosterone booster or fat burner supplement.

Urtica Diodica 

Also known as stinging nettle root extract, this has shown promising signs of being able to improve your testosterone levels. So it’s no surprise that studies have shown that it’s effective.

How does it work? As well as being able to sting you, this plant is able to reduce the amount of SHBG (which is responsible for lowering the amount of testosterone available to your system). As a result, this directly elevates your T levels, helping you make more muscle gains.

However, studies have also shown that you need at least 150mg urtica diodica for it to work. As there’s only 80mg in XenaTest Hardocore, it might not be very effective here.

Boric Acid 

Otherwise known as hydrogen borate, this contains boron (a mineral that’s shown to positively affect testosterone. Basically, boron is believed to be leftover from the big bang, and studies have shown that it works to raise your T levels.

However, we’re not sure why Superset Nutrition didn’t simply add boron instead of boric acid in XenaTest Hardcore.

Copper Glycinate & Zinc 

This can be a good addition to a supplement containing zinc, which XenaTest Hardcore does. Basically, it’s shown to be beneficial to balance your levels of zinc and copper to keep your body running at peak levels.

However, it’s only recommended that you consume a ratio of 10:1 (zinc:copper), so there should only be 1mg in this product; as XenaTest Hardcore contains 5mg copper and 9mg zinc, your level of these minerals won’t be balanced anyway.

Vitamin D3 

Superset Nutrition has saved the best ingredient until last here. In a nutshell, vitamin d3 has shown to be one of the most effective ingredients at boosting your T levels – making it a perfect addition to a testosterone booster supplement.

However, studies have shown that you need at least 3,332IU for it to work; as XenaTest Hardcore only contains a tiny 5mg dosage, vitamin d3 won’t work here.

It’s a shame that Superset Nutrition has underdosed this ingredient, but again, this is a reminder of how important getting the dosage right is.

Pros and Cons


  • Contains vitamin d3 & d-aspartic acid
  • Urtica diodica shown to promote test levels


  • Every ingredient has been underdosed (likely to be ineffective)
  • Missing other key test boosting nutrients
  • Contains ineffective nutrients

Side Effects

One of the best things about XenaTest Hardcore, is that it doesn’t contain any nutrients that’ve been reported to cause side effects. As a result, this seems to be quite a safe test booster supplement – but that doesn’t mean it’ll work either.

Review Conclusion

Superset Nutrition must have done some research while formulating this test booster supplement; they’ve added some great ingredients, such as vitamin d3, d-aspartic acid and urtica diodica.

However, they’ve made the same mistake as other companies, by not dosing these nutrients correctly. Ultimately, this means that this product, as a whole, isn’t likely to be effective.

As a result, this is also why it’s important to research the optimal dosages of ingredients inside the products you’re interested in buying. So you’ve made a great choice by visiting our website and reading this review today.

But unfortunately, XenaTest Hardcore doesn’t contain the necessary nutrient profile to compete with the best testosterone boosters on the market.
