About The Product

Testo HT is a testosterone booster by Eiyolab. It costs €25.90 on Toutelanutrition.com for 30 serving containers, with a serving size of 3 capsules per day.

This is a good serving size; studies have shown that 3-4 daily capsules is optimal for keeping your body topped throughout your day.

Anyway, well analyze Testo HTs nutrient profile for you in the next section. But first, well try and find out more about the company behind it.

Who are Eiyolab? 

Eiyolab are a supplements company that appears to be based in France, where they have become a popular brand. It markets a variety of supplements, from fat burners to protein powders.

In all honesty, we couldnt find much more information about them (such as the year they were founded). But 1 thing we do know is which ingredients are inside Testo HT - so lets take a look…

Testo HT Ingredients Explained

Our first impressions of Testo HT are pretty good; it doesnt contain any proprietary blends, meaning you can see the exact dosage of each ingredient.

However, we can also see that Testo HT is missing some key testosterone boosting nutrients such as Vitamin D3 (which has proven to raise your T levels effectively).

Not only that, theres one problem we can see straight away; this T-Booster contains Tribulus Terrestris, which has been reported to increase the weight of your prostate, which can cause serious male health issues in the future.

Anyway, well expand on everything as we take you through each ingredient inside Testo HT. By the end of this review, youll know how safe and effective this product really is.


Heres Everything You Need To Know:

Tribulus Terrestris 

We just mentioned that Tribulus Terrestris can cause an increase in your prostate weight. This is a side effect you should avoid at all costs, as it can lead to serious male health issues in the future.

But the worst part is that Tribulus Terrestris hasnt shown to have any effect on your testosterone levels. The only thing its able to do, is slightly raise your sex drive (but its not worth it, due to the potential side effect this ingredient can cause).


In case youre unaware, this is a vegetable that belongs to the brocolli family, commonly grown in Peru.

We believe that Eiyolab has added this nutrient into Testo HT to try and counteract the side effect of Tribulus Terrestris; Maca might be able to reduce the increase in prostate weight, but its not shown to be 100% reliable at delivering this benefit.

But the good news is that Maca has shown to raise your libido, which is a useful benefit to have in a testosterone booster.

Saw Palmetto 

Also known as Serenoa Repens, this is another ingredient thats believed to suppress the side effect of Tribulus Terrestris (prostate growth).

However, Saw Palmetto hasnt shown to raise your testosterone levels in many studies - making it an unreliable ingredient in Testo HT.

Also, we dont like that Eiyolab have added nutrients specifically to counteract Tribulus Terrestris side effect; it doesnt even raise your testosterone levels, so they should have simply left it out of Testo HT completely.

Avena Sativa 

If youre thinking that this some kind of complex ingredient, then youll probably laugh when you hear what it is - oats.

Yes, its the same oats that is used in porridge. It might be a healthy source of carbohydrate, but its not going to raise your testosterone levels.

Ultimately, we would have rather Eiyolab added a tried-and-tested nutrient at raising your testosterone, such as Vitamin D3.

Fenugreek Seed Extract 

Finally, this is a key testosterone boosting ingredient in Testo HT.

Fenugreek has proven to raise your test levels and libido, making it a perfect addition to any T-Booster supplement. Its also one of the most efficient nutrients, as its shown to work in dosages as little as 50mg per serving.

As Testo HT contains 200mg, its likely to work here. Good job by Eiyolab.

Poivre Noir 

This is simply Black Pepper Extract (the same stuff you sprinkle on your food to make it taste better).

However, its more useful than you think; Black Pepper Extract has shown to improve your digestion and the absorption rate of supplements its added to.

But the problem is, it doesnt have any effect on your testosterone levels. So while it can be a great bonus to have in supplements, its not really needed either.


We dont understand why companies add L-Arginine in their testosterone booster supplements; it has no effect on your test levels, and only a minor effect on your blood flow.

Basically, we believe that companies add L-Arginine in an attempt to strengthen your erections. But its not shown to be reliable at delivering this benefit, due to L-Arginine having a poor absorption rate when orally supplemented.

For this reason, we consider this to be mostly an ineffective addition to Testo HT.


L-Ornithine is another ingredient thats added to supplements in an attempt to improve your blood flow. However, its not proven to deliver this benefit either.

If Eiyolab wanted to improve your blood flow, then they should have added Citrulline Malate.

But in any case, this shouldnt be a key benefit you look for when choosing a testosterone booster. The main focus should be on you raising your testosterone levels.


Zinc is a very useful ingredient in any testosterone booster, as its proven to help support peak testosterone levels in countless studies.

In fact, its an essential mineral that is commonly known to be beneficial for many things (general health, less fatigue, test levels).

The only issue is that you shouldnt consume more than 40mg per day, as this is the TUL (tolerable upper limit). But this isnt a problem in Testo HT, as it only contains 15mg per serving.

Ultimately, this serving size is enough for you to benefit from, while allowing you to consume other foods containing zinc. Good job by Eiyolab here.

Most Effective Test Booster Ingredients

As this TestoTek review is quite negative, we dont want to seem like were criticizing it without any evidence to back up our claims. For this reason, were giving you a quick overview of what you should be looking for on your search for the best testosterone booster.

Simply put, the best T-Boosters deliver these benefits:

  • Increased Testosterone Production
  • Enhanced Libido
  • Pack on Lean Muscle Faster

We strongly believe that these are the 3 key benefits of purchasing taking these supplements - why else would you buy one?

Personally, these are the main reasons why we tried numerous testosterone boosters - before finally finding our top 3 favorite products. The reason why it took almost 20 years to find a test booster that actually works, is because theres so much sh*t on the market - it was like trying to find the best grain of sand in a beach.

Anyway, especially after starting to work in the supplements industry, we noticed that there were key ingredients to look for in these supplements…

Here are the ingredients proven to raise testosterone levels:

  • Vitamin D3 - This is technically a hormone thats proven to be safe and reliable. This is how good it is: Doctors believe if youre going to choose just one ingredient to benefit your overall health, then Vitamin D3 is the best option. Whats even better, is that its shown to significantly increase testosterone levels in numerous studies. One thing to remember; make sure to consume the optimal dosage (at least 3,332IU per serving).
  • D-Aspartic Acid - DAA  is very important, as it helps to regulate your testosterone levels. For this reason, giving your body a helping hand by supplementing between 2,000mg-3,000mg can really give you that kick of testosterone that you need as you get older. DAA is one of our favorite ingredients, and deserves a place on this list.
  • Fenugreek - This herb has been used in ayurveda (traditional Indian) medicine for centuries. So what does it do? Well, its proven to boost libido and testosterone levels in numerous studies. The best thing about Fenugreek, is that its effective in dosages as small as 50mg (meaning Frenugreeks a reliable addition to any T-Booster that you dont need in huge amounts).
  • Asian Red Panax Ginseng - This is not often seen on ingredient lists of testosterone boosters - its not well known, and we know that companies prefer to add more reputable ingredients such as Tribulus Terrestris (but Tribulus Terestris has shown to be ineffective in numerous studies). This is where Asian Red Panax Ginseng comes in; its proven to have a positive effect on your T-Levels, and even your general health (making it an all-round great ingredient).

Side Effects

The only side effect you need to be concerned about with Testo HT is possible prostate enlargement - due to it containing Tribulus Terrestris.

Eiyolab have added Maca and Saw Palmetto to try and counteract this side effect. But Saw Palmetto has been reported to cause numerous side effects itself.

Heres the potential side effects from taking Testo HT: 

  • Enlarged prostate (Tribulus Terrestris)
  • Nausea (Saw Palmetto)
  • Headache (Saw Palmetto)
  • Diarrhea (Saw Palmetto)

Testo HT Review Conclusion

Eiyolab hasnt done a bad job with Testo HT here. Its likely to boost your libido, which is a great benefit from taking a testosterone booster.

However, Eiyolab seem to have forgotten to include ingredients that are proven to actually raise your testosterone levels.

Ultimately, a raise in test levels will result in most key benefits (such as raised libido, strength, mood and confidence). For this reason, we dont believe Testo HT can compete with other products containing optimal amounts of key ingredients such as Vitamin D3.
