TestoLabs Review


TestoLabs is a testosterone booster by a company also called TestoLabs. It’s worryingly similar to one of our favourite testosterone boosters, TestoFuel, but TestoLabs’ ingredient list doesn’t match up.

Claimed to promote:

  • Testosterone levels
  • Libido and sex drive
  • Lean muscle growth

We’ve analyzed this product to see whether it’s simply a bad copy of a market leader, or whether it can hold its own as a testosterone booster.

Take a look:


About the Company

We couldn’t find much information about this company. They only inform you that this testosterone booster is their “most advanced, researched and complex muscle building supplement” they’ve ever produced. This is interesting, as it looks like this is their first product.

There’s another thing that concerns us about this product – TestoLabs doesn’t come with the box that it’s pictured with on their website. Already, we’ve started to think that this company is only concerned about its profit margin and isn’t bothered about giving customers great value for money.

The one thing we could find out about TestoLabs is that they’re based in Leeds, England. This could mean trouble if you’re a customer in America as it could take a while to get to you. Their address comes up as a residential house instead of an established office, which could mean that these products are created in someone’s house, not in any cGMP or FDA approved facility – this risks the safety of this product.

However, instead of speculating, let’s analyze TestoLabs’ contents and see whether it’s an effective testosterone booster.

The Ingredients and How They Work

The bottle and color scheme of this product are strikingly similar to one of the market leaders in testosterone boosters, TestoFuel. Even the ingredients are similar, but the doses are different – the dosages in TestoLabs are significantly smaller than its established competitor, TestoFuel.

See for yourself:


Tribulus Terrestris 

The roots and fruits of this plant are believed to possess testosterone boosting, libido enhancing properties. It’s for this reason that Tribulus Terrestris is sometimes used in testosterone booster supplements.

However, numerous studies have shown that Tribulus Terrestris doesn’t deliver any improvements in healthy males. Even the evidence for the increase in testosterone in infertile men isn’t strong enough to state it helps them.

The worrying thing is that this ingredient takes up the majority of this product (1,000mg), meaning that it could be in danger of being ineffective overall.

Also, Tribulus Terrestris comes with risks of side effects – it can cause an increase in prostate weight and is possibly unsafe to consume by those pregnant or breastfeeding, which are concerning.

D-Aspartic Acid 

This is a great ingredient to have in a testosterone booster. It’s an amino acid that encourages the release of hormones such as luteinizing hormone, follicle-stimulating hormone, and growth hormone.

However, here’s where the problems start with TestoLabs. The optimal dose of D-aspartic acid is between 2,000mg-3,000mg, and there is only 500mg contained in this product.

This means that the D-Aspartic Acid will be ineffective – TestoLabs have seriously underdosed this ingredient and should’ve increased the amount of D-Aspartic Acid to 2,000mg-3,000mg to give you its full benefits.

Asian Red Panax Ginseng 

This is part of the plant family of ‘Ginseng’ and is effective in boosting your mood, immunity, mental function (memory and reaction time). It’s also effective in improving the quality of your erections, testosterone, and exercise.

This is a great ingredient to have in a testosterone booster, and we recommend that you look out for Asian Red Panax Ginseng on your search for a quality product.

Cordyceps Sinesis 

This is a mushroom that’s traditionally used in Chinese medicine as it’s believed to possess anti-aging and testosterone boosting properties.

However, there haven’t been any studies that have proved Cordyceps to be effective in raising your testosterone levels – also, the patients in the studies were given 1,000-3,000mg daily. There is only 125mg of this ingredient in TestoLabs, so there is no chance of it being effective in this product.

Also, Cordyceps comes with risks of side effects such as diarrhea, dry mouth, and nausea, which would ruin your workout and progress in the gym. We recommend that you stay away from this ingredient to avoid these side effects, and search for a product that’s free from side effects.


This is a herb that’s popular in India and Arabic regions, which is proven to enhance your libido and testosterone levels.

It works as one of its compounds, 4-hydroxyisoleucine, regulates glucose metabolism – it’s shown that testosterone levels can decrease by 25% after you take on a glucose load, so keeping your glucose levels balanced means keeping your testosterone levels high.

Fenugreek is a great addition to any testosterone booster and you should look out for it on your search for a quality T-booster.

Vitamin D3 

This is the best ingredient in TestoLabs, as Vitamin D3 is technically a hormone. It’s been proven to boost your testosterone levels when taken around its optimum dosage of around 3,332IU daily.

Here’s where we run into a problem with TestoLab. They’ve made a huge mistake in seriously underdosing Vitamin D3 in this product, as it’s the most beneficial ingredient in boosting your testosterone.

We strongly recommend searching for a product that allows you to have 3-4 servings spread throughout the day, with a Vitamin D3 serving size of over 3,332IU (it’s safe to consume up to 10,000IU per day).


TestoLabs looks like a cheap rip-off version of market leading testosterone booster, TestoFuel. It doesn’t even come delivered with the box pictured above.

Side Effects

Although the majority of the ingredients in TestoLabs are side effects free, there are two that have cause for concern – Tribulus Terrestris and Cordyceps.

These two ingredients can cause such side effects as an increase in prostate weight, diarrhea, nausea, and dry mouth, which would ruin your workout.

Here’s a list of the possible side effects from taking TestoLabs:

  • Increase in prostate weight (Tribulus Terrestris)
  • Diarrhea (Cordyceps)
  • Nausea (Cordyceps)
  • Dry Mouth (Cordyceps)

TestoLabs Review Conclusion

While TestoLabs has a fairly good ingredients list, the dosages of the ingredients inside ruin this product – most of the ingredients aren’t in their optimal amounts, meaning it could be a ineffective product overall.

Also, this testosterone booster includes two ingredients that come with risks of side effects such as increased prostate weight, which is very worrying.

We recommend searching for a product that contains optimal amounts of such ingredients as Vitamin D3, Fenugreek, Asian Red Panax Ginseng, and D-Aspartic Acid to ensure you receive an effective, top quality product that gets you results.

Also, it’s important that you make sure any supplements that you buy are manufactured in a cGMP and FDA approved facility. This ensures that the product you use is safe and was created to a high standard under strict regulations – We couldn’t find any evidence that TestoLabs is manufactured in any cGMP or FDA approved facility, only that their address provided on their website is a residential house.

Ultimately, this could mean that what you’re getting is effectively made in a house in potentially unhygienic conditions – this would also mean you’re getting an unsafe product and are risking your health by taking it.
