About The Product

SkyTest is a testosterone booster made by Cell Nature Labs. It costs $49.95 for 30 serving containers, with a serving size of 2 capsules per day; studies have shown that 3-4 capsules daily is better for keeping your body topped with nutrients needed to raise your T levels, so this isnt great.

Anyway, well take analyze SkyTests nutrient profile for you in the next section. But first, well tell you more about the company behind it.

Who are Cell Nature Labs? 

Cell Nature Labs are a fairly new supplements company; we believe they were founded in 2016, but there wasnt any evidence to prove this on their website.

We did see that they offer 4 products, including a fat burner and this testosterone booster. But there was a serious lack of information on their website, so we hope that they create an about us section to provide customers with more info in the future.

Anyway, none of this affects the quality of SkyTest, so lets stop wasting time and see whats inside this testosterone booster below…

SkyTest Ingredients Explained

SkyTest contains 7 main ingredients that well analyze for you in this section. This is a good amount to have, as we always prefer supplements containing under 10 nutrients (as theyre usually dosed better).

We have very mixed first impressions of this testosterone booster; it contains some great ingredient such as Fenugreek Seed Extract and Stinging Nettle Root Extract, but every ingredient is part of a proprietary blend (well expand on this below).


Proprietary blends are mixtures of numerous ingredients thatre only shown to you as 1 quantity. As you can see from the SkyTest Blend on this products ingredient list, the overall amount is 1350mg - but youre not shown the dosages of each ingredient inside such as Tribulus Terrestris.

This increases your risk of side effects, and also makes it uncertain whether this testosterone booster will work. For this reason, we try to avoid any supplement that contains proprietary blends.

Anyway, now that you know why we dont like test boosters, well take you through each ingredient inside SkyTest. By the end of this review, youll know exactly how safe and effective this product really is.


Heres Everything You Need To Know:


L-Citrulline is a great addition to pre-workout supplements, as its proven to increase your nitric oxide levels; this leads to you experiencing enhanced muscle pumps in the gym.

However, while this benefit is great for when youre working out, its not really needed in SkyTest.

Why? Because the main reason you buy testosterone boosters is to enhance your T levels - not your muscle pumps.

Cell Nature Labs should have replaced L-Citrulline with a tried-and-trusted test boosting nutrient such as Vitamin D3 instead here.


Alright, so we just told you that L-Citrulline was an unnecessary addition to SkyTest. Well, L-Arginine is even worse, as it has a poor absorption rate - so its not likely to work.

What does it do? Well, its believed to offer the same benefit as L-Citrulline, so theres no need to have both in 1 supplement anyway.

Ultimately, the only thing you need to know here, is that L-Arginine has no effect on your testosterone levels.

Tribulus Terrestris Extract 

Tribulus Terrestris was once one of the most popular test boosting ingredients in the industry. But its being less and less used in supplements now, since modern research found that its able to increase the weight of your prostate (which can lead to serious male health issues).

Not only that, the same studies have shown that Tribulus Terrestris doesnt even have any effect on your T levels. However, we will acknowledge that it can raise your libido.

Ultimately, nutrients that target your libido arent needed in T-Boosters; if you consume nutrients to raise your testosterone, then your libido will naturally rise and stay that way too.

Not only that, as Tribulus Terrestris has been placed in a proprietary blend, your risk of side effects are seriously increased. For this reason, we usually recommend that you avoid products containing this ingredient.

Maca Root Extract 

Maca Root Extract is known for its ability to enhance your libido, which makes it a good bonus nutrient to have in a test booster supplement.

However, as its not able to raise your testosterone levels, we dont consider it to be a key addition in SkyTest. Again, we would have preferred to see a proven nutrient such as Vitamin D3 here.

Fenugreek Seed Extract 

Finally, this is a key addition to any testosterone booster; its been proven to raise your T levels in countless studies, and its even been used in ayurveda (traditional Indian Medicine) for decades.

Not only that its shown to work in dosages as small as 50mg per serving; so even though its inside a proprietary blend, its more than likely to still be included in this amount.

However, we would much rather SkyTest didnt contain any proprietary blends.

Stinging Nettle Root Extract 

Stinging Nettle Root Extract is another good addition to any test booster; its shown to have a positive effect on your T levels too.

However, its not the most reliable ingredient, as we have to point out that theres been studies showing that it doesnt deliver significant results. So its especially important that you consume at least a 100mg dosage of Stinging Nettle Root Extract.

So as you probably know by now, the main problem is that this nutrient is contained in a proprietary blend - so you dont know the exact dosage inside SkyTest.

Eurycoma Longifolia Extract 

In case youre wondering, this is a herb thats also known as Longjack or Tongkat Ali. Its very similar to Maca Root Extract, as its also shown to improve your libido.

However, the bad news is that Eurycoma Longifolia Extract has no effect on your testosterone levels either. For this reason, while it can be a good bonus to have in SkyTest, its not really necessary either.

Side Effects

As weve mentioned throughout this review, your risk of side effects are always increased when companies add every ingredient inside their products to proprietary blends.

This is a problem, as SkyTest contains Tribulus Terrestris, which has been reported to cause prostate enlargement on numerous occasions. For this reason, we advise that you try to avoid supplements containing Tribulus Terrestris - especially when its added into proprietary blends.

Heres the potential side effect from taking SkyTest: 

  • Enlarged Prostate (Tribulus Terrestris)

SkyTest Review Conclusion

We might sound like weve been very critical of SkyTest in this review, but we always try to be as honest with you as possible. And when companies dont add many nutrients that are proven to actually raise your T in test booster supplements, its not going to guarantee results.

Ultimately, we wish that SkyTest contained some tried-and-tested nutrients, such as Vitamin D3; experts and nutritionists recommend Vitamin D3 as one of the most important nutrients to consume to improve your general health and testosterone levels.

Cell Nature Labs SkyTest Review

Bottom Line

SkyTest doesnt contain the necessary ingredients to raise your testosterone levels, and comes with the risk of a side effect.

For this reason, we dont think it can compete with the highest rated testosterone boosters on the market.
