Reviewed Product: TestoTEK
TestoTEK is a testosterone supplement that aims to help both young and older men, as well as active and inactive men improve their bodies’ production of testosterone. While pricey, it does come with 12 100% natural ingredients whose efficiency and health benefits are backed by science.
TestoTEK is relatively new on the T booster market, and there aren’t so many reviews that cover this supplement out there. So, I decided to do my own research by checking out what other customers have to say, giving it a try myself, talking with TestoTEK’s customer reps, and researching the ingredients themselves.
Due to its versatile ingredient list, Testo TEK is a perfect choice for just about any man out there. Whether you’re just dealing with fatigue and lack of motivation, are active only in your spare time, or are an athlete or full-time gym-goer, TestoTEK has got you covered.
In fact, I think it’s safe to say that TestoTEK would be ideal for pretty much any man who is over 30. After all, after men reach 30 years of age, their T levels start to drop. And TestoTEK’s main marketing slogan is that it’ll help your body start producing testosterone like it did “in your twenties.”
The Testo TEK natural testosterone booster relies on a mix of 12 scientifically-tested ingredients that are proven to both improve T levels and male health. The main goal of this supplement is to trigger the production of testosterone throughout your body, and focus on (and fix) the any low testosterone symptoms you might be dealing with, such as:
Besides boosting testosterone levels, TEK Naturals claim their product can also:
First, I want to mention that TestoTEK contains 12 ingredients, even though it might seem like it only has 11 ingredients at first. That’s likely because, on their website, they don’t mention one ingredient (Vitamin K) in the main copy on the Ingredients page. However, that ingredient is present on the booster’s label.
With that out of the way, the number is more than decent. It really makes you feel like you’re getting your money’s worth to be honest.
Better yet, all of the ingredients found in Testo TEK are completely natural. That’s not just a sales pitch used by TestoTEK’s marketing team. I went over all the ingredients on their website, did my thorough research, and saw for myself just how efficient and “clean” they are.
In fact, I’ll go ahead and share my findings with you:
Vitamin D3’s main purpose in relation to T levels is to lift free testosterone levels and slow down the rate at which testosterone gets converted into estrogen. The second issue actually tends to happen to older men at a faster rate.
And it’s already a well-known fact that Vitamin D, in general, has positive effects on testosterone production. For one, here’s a study that clearly shows that mean with lower Vitamin D levels in their blood serum had way less testosterone than men with higher Vitamin D levels.
Here’s another study that should bring a smile to any man who’s over 30 years old as well. According to it, Vitamin D supplements can help older men to avoid dealing with low T levels in their bodies. What’s more, this research shows how low Vitamin D levels in older men are associated with low testosterone levels as well.
Besides aiding with testosterone, Vitamin D3 has other perks as well:
All in all, Vitamin D3 is an excellent ingredient that should be present in any testosterone supplement to be honest. My only concern is that the dosage is too low. Normally, to get the best results, you should get around 125 Mcg per day, not 50.
Quite unsurprisingly, low levels of Vitamin B6 in the body are actually associated with low T levels. Don’t just take my word for it - here’s a study that proves that. Basically, it all comes down to the fact that Vitamin B6 is essential when it comes to healthy testosterone production in the body.
“Yeah but that study was done on male rats not humans!”
Yes, I’m aware of that, but you should also be aware that Wistar rats have reproductive organs that are similar to ours - well, except for the size, of course.
Oh, and here’s another thing worth mentioning - Vitamin B6 promotes the production of androgens. Don’t forget that androgens are directly correlated with high T levels in the body.
Furthermore, Vitamin B6 can also keep prolactin levels down in your body. If you’ve never heard of “prolactin,” I think it’s enough to say that it’s the hormone responsible for the “man boob” look, as it causes a drop of testosterone levels.
Another thing I really like about VItamin B6 is that it’s known to improve your mood, and get you to feel more motivated.
Vitamin B2 has been known to be an efficient energy-booster, something that would definitely come in handy if you like to hit the gym on a regular basis. But there’s more to this little vitamin than that. For one, Vitamin B2 is an antioxidant, which means it benefits testosterone greatly since it can help combat the age-related reduction of testosterone.
Oh, and since it’s an antioxidant, that also means it fights free radicals - substances that are associated with nasty health issues like cancer development, for instance.
What’s more, Vitamin B2 also acts as a testosterone 5 alpha-reductase inhibitor. That’s basically a fancy way of saying that it can slow down the rate at which testosterone is converted into dihydrotestosterone, an endogenous androgen that has been known to cause pattern hair baldness and prostate issues.
This is definitely a top-notch addition. It’s not called the “testosterone vitamin” for nothing. That’s because this vitamin helps your body produce cholesterol. And contrary to popular belief, cholesterol is actually extremely important for your T levels!
How come? Well, consider this - cholesterol is a precursor for all your male sex hormones, including testosterone. The Leydig cells in your gonads convert cholesterol into testosterone. And if you body doesn’t have enough cholesterol, your liver will start synthesizing it.
If you find that hard to believe, here’s a study that should put your fears to rest - it clearly shows how high levels of high density lipoprotein cholesterol have a positive impact on T levels.
And, once more, if you are an avid gym goer, this ingredient will really work in your favor. That’s because Vitamin B5 manufactures red blood cells that carry oxygen throughout the body, which - in turn - helps with performance-based training.
Few people know about Vitamin K2 since its K1 counterpart seems to be more popular. While Vitamin K1 has some positive effects, K2 has some testosterone-boosting properties that shouldn’t be overlooked either.
Here’s a Japanese study that should show you what I mean. Basically, the Wistar rats that were administered Vitamin K2 for 5 weeks, showed an over 70% increase in plasma testosterone levels (and an almost 90% increase in the testicles).
Again, please don’t forget that male Wistar rats have a reproductive system similar to ours.
Other things that make Vitamin K2 such a great addition to this supplement are the way it enhances bone formation, how it reduces prostate cancer risk, and how it can reduce the risk of dealing with cardiovascular diseases.
You wouldn’t really expect a bean-like climbing herb from India to aid with testosterone production, but here we are. Here are 3 studies I managed to find that showcase just how vital it is:
True, Mucuna Pruriens doesn’t have too much of a huge impact on fertile men, but the testosterone boost offered by the plant is still decent. Plus, the plant can lower estrogen and prolactin levels in the body too.
And here’s another great thing about Mucuna Pruriens - it provides L-Dopa, a precursor to the brain neurotransmitter and hormone dopamine which helps to create the human growth hormone in your body. Essentially, that means it makes it easier for you to burn stored fat, and gain lean muscle mass to achieve that “ripped” look.
First and foremost, Zinc is quite an excellent estrogen-blocker. Furthermore, it also has libido-boosting properties, as seen in this study conducted on male rats. Again, human males have similar reproductive systems to male rats, so the results are very relevant.
Also, please keep in mind that low levels of Zinc in the body have been associated with severely decreased testosterone production.
Plus, if you’ve got an active sex-life, TestoTEK will really come in handy with its Zinc ingredient, since ejaculating can actually deplete your body of up to 5 Mg of Zinc!
It’s true that Fenugreek doesn’t have a particularly strong impact on testosterone levels (though it still helps with them to a certain extent since it has antioxidant properties), but that doesn’t mean it isn’t useful for a man’s health.
After all, this herb can naturally enhance your sexual performance! The saponins (chemical compounds) found in Fenugreek actually aid in increasing the sex hormones in your body.
Fenugreek also seems to be extremely efficient when paired up with Zinc and Magnesium. While TestoTEK doesn’t feature any Magnesium, it does contain Zinc, so that’s still nice.
Lastly, keep in mind that Fenugreek has a positive effect on muscle development as well. That’s because it increases the release of insulin in the body.
One thing you should know about testosterone is that the Sex-Hormone Binding Globulin (SHBG) likes to attach itself to it, essentially making some of the testosterone inactive. The good news is that some of the substances found in Stinging Nettle Root can block this issue to a certain extent, as they attach themselves to the SHBG.
In turn, that leaves testosterone free to roam in your body’s bloodstream, effectively meaning that the free testosterone levels in your body will rise.
Oysters are a pretty good aphrodisiac, and can actually help improve performance in bed, and this has been known since the Roman Empire (and well all know how “interested” those guys were in sex).
Plus, keep this in mind too - oyster extract contains decent amounts of Zinc as well. And you’ve just seen how beneficial Zinc is for T levels, so adding a little extra would definitely come in handy. Oh, and oyster extract contains some Vitamin D as well, which - again - has positive effects on T levels.
I got to say this ingredient is a nice surprise. Trust me, oyster body extract is much more pleasant than chugging oysters on a regular basis (unless that’s something you actually like).
Siberian Ginseng seems to be used in many alternative medicine practices, but one thing that stands out to me (and I’m guessing it’s gonna stand out for many of you too) is the fact that it can increase blood flow and nitric oxide that goes to the penis. In short, that means it can help increase sexual performance in bed.
Siberian Ginseng is also used to help lower blood pressure, improve heart health, and enhance the immunity system - some properties that are nice to have access to.
While there aren’t any conclusive studies that link Siberian Ginseng to enhanced testosterone production, the benefits mentioned above definitely make it a decent addition.
D-Aspartic Acid is quite well-known for its ability to help produce sperm cells and sex hormones - especially the luteinizing hormone. If that doesn’t ring any bells, keep in mind that the luteinizing hormone is the one that’s responsible for kick-starting the Leydig cell production of testosterone in your body.
What’s more, according to some research, D-Aspartic Acid can help improve the quality of a male’s sperm, and even help out infertile men (well, to a certain extent, naturally).
Besides that, here’s a study that showcases just how important D-Aspartic Acid is for optimal testosterone production. Long story short - men who took D-Aspartic Acid over 12 days experienced an increase of 42% in T levels.
This is where things get a bit complicated, funny enough (since you’d think this should be straightforward normally). Don’t worry - you don’t need to do anything complicated to take Testo TEK since it comes in capsules. Even better, no chemicals or dyes are used to color the capsules.
The problem arises when you try to figure out just how many capsules you need to take per day. All in all, after some research, I ended up with 3 answers! Basically:
A bit of confusion that can make you wary of trying it out when you’re ready to purchase to be honest. Personally, I went with the 4 capsules/day since that’s what the facts sheet recommends, it’s what others have done too, and I’ve even asked their customer support about this, and that was the dose I was recommended to take.
If you want to be sure, you can also contact their customer support to ask them about this.
According to TEK Naturals, you should take TestoTEK up to 3 to 6 months, or even longer preferably. Even just one month of Testo TEK can offer some results, but TEK Naturals themselves say it’s not a realistic plan for a real change - and I agree with them. It’s the same with any testosterone booster, in fact.
BurnerTEK is a fat burner that’s also manufactured by TEK Naturals. If you’ve heard of both that and TestoTEK, you might be wondering if taking the 2 together is a good idea.
Well, I believe it’s safe to say it is - TEK Naturals themselves promote that, in fact, since they’ve got a combo pack sales of TestoTEK + BurnerTEK on their main website. Taking the 2 together shouldn’t cause any issues, since Testo TEK focuses on your body’s production of testosterone, while BurnerTEK targets your body’s metabolism, aiming to increase it.
It doesn’t take a scientist to know that high testosterone production + high metabolism = an incredible physique - provided you do your part in the gym, or engage in any other physical activities.
Plus, BurnerTEK contains 12 natural ingredients as well, so you don’t need to worry about exposing your body to any harmful chemicals.
In terms of results, it all depends on what your expectations are, and what you are taking Testo TEK for. For instance, if you’re looking to put on muscle mass, burn fat, and overall get ripped, you’ll likely only start seeing results after 5-6 weeks, or even more.
But please remember that to get the best physical results, you should engage in a workout program too. It’s what TEK Naturals recommend as well.
If you’re looking to improve your mental fortitude, libido, and energy levels, you might notice changes taking place within the first or second week of taking TestoTEK.
In my case, I started noticing that - after one week of taking TestoTEK - my libido got a decent boost (I’m not going to go into details about that, so you’ll just have to take my word for it), and I become a bit more motivated and full of energy than usual.
Around the 3 week mark, I also started noticing that I recovered faster after my gym sessions, and that I started being able to lift heavier weights.
Even though this is a completely natural T booster, there’s still a chance you might encounter side effects. Now, I’m not saying that’s guaranteed to happen, but according to this study, testosterone boosters can cause side effects such as:
Keep in mind that study doesn’t specifically refer to TestoTEK, but to testosterone boosters in general. Also, those side effects are more likely to be experienced if you take testosterone or hormone supplements together.
Personally, I haven’t experienced any issues. I have read some reviews where people complained about developing acne after taking TestoTEK. While that can happen, it’s important to understand that acne is also a sign of high testosterone. After all, high T levels will cause the sebaceous glands to produce more sebum, likely resulting in pimples.
To prevent that issue or better contain it, just be extra diligent with your body hygiene. You could also try using some skin clearing products, or just talking with your dermatologist about it.
All in all, I’d say TestoTEK is generally safe, though if you have any concerns, you should definitely talk to your doctor before taking the booster. Test driving the booster for a few weeks to see how you’re feeling is also a good idea.
For the most part, you’ll be able to purchase TestoTEK directly from TEK Naturals. The pricing isn’t too appealing for a single box ($69.99), but you can get one for $59.49 if you use the Auto-Ship Policy.
Basically, it lets you choose to have TestoTEK delivered to you every 30, 60, 90, and 120 days. It isn’t too bad, as it gives you a 15% discount on every order, and you can stop the program whenever you want (just make sure to do it at least 24 hours before the next order).
You can also get bulk deals to save more money, with 3 boxes ($189.97) saving you $20, and 6 boxes ($319.96) saving you $100. Plus, the website also gives you a (quite spammy) 10% discount coupon whenever you try to leave, so that’s nice.
I’ve also managed to come across TestoTEK products on Amazon, and they are being sold by TEK Naturals, but the price just isn’t appealing. For example, this bottle of TestoTEK will cost you $74.99.
Both supplements aim to enhance your body’s production of testosterone, with TestoFuel also aiming to optimize your body’s metabolism and HGH production. Basically, that means TestoFuel tries to act as a fat burner on top of just being a T booster. Both supplements work well for young and older men who engage in physical activity, or who aren’t very active.
Compared to TestoTEK’s 12 ingredients, TestoFuel only has 9 ingredients. Here’s a quick rundown:
It’s pretty obvious both supplements rely on the same ingredients, with TestoTEK adding a bit more into the mix. But while TestoTEK has the upper hand regarding the number of ingredients, TestoFuel handles dosages better in certain regards. For example, TestoFuel offers a better dosage of Vitamin D and D-Aspartic Acid. Also, I can’t overlook the fact that TestoFuel also has Magnesium.
In terms of side effects, I haven’t come across any specific info (other than cases of acne) saying one supplement is “safer” than the other. I believe it all depends to how your own body responds to each supplement.
When it comes to pricing, a box of TestoFuel ($52.99) is definitely much cheaper than a box of TestoTEK ($69.99). The TestoFuel 3-box bundle is also more attractive, as it only costs you $158.98 (compared to TestoTEK’s $189.97 bundle), and you get a free extra box as well.
On the other hand, TestoFuel doesn’t have an Autoship policy that offers discounts. Though, they do make up for that with free worldwide shipping on some deals + a 90-day guarantee.
In the end, it’s up to you which deals sound more appealing to you. If you’re from the US, TestoTEK would be a decent choice since they offer free shipping in that country. Of course, if brand history and precision dosage is paramount to you, TestoFuel would be a better choice.
Both TestoTEK and Prime Male aim to do the same thing - improve your libido and strength, enhance your vitality and mental fortitude, and increase the production of T in your body. Both supplements are marketed as being ideal for men who are over 30, and both of them have 12 natural ingredients in their formulas:
Both formulas are pretty efficient at what they do in my opinion, though I do like that Prime Male has Magnesium, and the well-known T-enhancer: Boron. Also, Prime Male gets the Vitamin D dosage right as well.
When it comes to side effects, I have noticed more people complaining about Prime Male than TestoTEK. While the most complaints I’ve found regarding TestoTEK were related to acne, Prime Male side effect-related complaints included:
Naturally, that can vary depending on your diet, how your body reacts to the supplement, and whether or not you are taking other supplements together.
A box of Prime Male (around $60) is more budget-friendly than a box of TestoTEK ($69.99). The 3-box bundle is cheaper too (around $173 compared to TestoTEK’s $189.97), and you get a free box + free worldwide shipping.
Another nice thing is that Prime Male comes with a 90-day money-back guarantee, which is definitely better than TestoTEK’s 30-day guarantee.
So, if you are on a budget, you’re better off with Prime Male in my opinion. But if money is not a concern, or you plan on making a long-term order, TestoTEK is a better option - plus, you can get some decent savings with their Autoship policy.
I’m not very sure why some people like to pit these two products against one and the other. TestoTEK is mostly a testosterone booster, while Virectin looks more like a male performance supplements (yes, THAT kind of performance).
In terms of ingredients, Virectin has more (16) than TestoTEK (12), though most of the ingredients found in Virectin are not exactly testosterone-enhancers. Still, here’s a quick overview:
As for side effects, Virectin seems to have the lead since I’ve found reviews of people complaining about issues like:
Of course, this mostly depends on how your body reacts to the supplement, but it’s still worth taking into consideration.
Price-wise, a bottle of Virectin is cheaper than a box of TestoTEK ($44.95 vs. $69.99), though it’s worth mentioning that a bottle of Virectin only comes with 90 capsules, while a box of TestoTEK comes with 120 capsules.
Both the 4-bottle ($179.80) and 5-bottle ($224.75) are more cost-efficient than TestoTEK’s bundles ($189.97 for the 3-box bundle, and $319.96 for the 6-box bundle). However, I’ve only seen mentions of standard shipping (which is free for $60+ orders) on Virectin’s website, meaning they probably only deliver in the US. TestoTEK, on the other hand, is shipped worldwide.
While Virectin might be able to raise your T levels a bit (thanks to the Zinc found in it), it definitely can’t hold a candle to TestoTEK. In my opinion, if you’re mostly looking for a libido boost, you should still choose TestoTEK over Virectin because it can help you with that. Plus, it seems way more trustworthy.
Oh, and keep in mind I have seen people complaining about Virecting not working for them at all.
No, it doesn’t.It’s true that, as T levels rise, so do estrogen levels, but - luckily - the Mucuna Pruriens ingredient that’s found in TestoTEK can lower estrogen levels in your body. Also, please keep in mind that Zinc (another TestoTEK ingredient) is an estrogen blocker as well.
It really all depends on what the rules of that specific competition say about supplements, and what the regulative authorities in your country have to say too. I highly recommend looking that up before ordering TestoTEK.
As far as I know, no. You can only purchase TestoTEK from the TEK Naturals website or on Amazon (also from TEK Naturals).
To my knowledge, yes. I researched all the ingredients found in TestoTEK in-depth, and found no traces of caffeine present in the supplement. In fact, some customers were happy that the energy boost they got from TestoTEK wasn’t the same “jittery” type of boost caffeine gives you.
Yes, it is, though it will cost you $25 extra to ship to countries outside the US, and $12.99 to ship to Canada.
I didn’t come across anything linking TestoTEK with prostate cancer in my research. The only thing that could be said about this is that TestoTEK contains Zinc, and Zinc has been linked with a probability of developing prostate cancer - but that’s only if you consume way too much Zinc on a daily basis (over 100 Mg/day). Luckily, TestoTEK only has 25 Mg of Zinc.
Plus, here are some good news - 3 ingredients found in TestoTEK might help combat prostate cancer:
This might happen if you combine testosterone supplements and hormones. The thing with prostate enlargement is that it’s mainly caused by chemical testosterone, and TestoTEK is 100% natural. Also, Stinging Nettle can allegedly help with an enlarged prostate as well.
It’s highly unlikely. Since TestoTEK will help raise your T levels, you shouldn’t have to worry about increased blood pressure levels - an issue commonly associated with low testosterone levels.
Not that I know of. To be honest, I can’t see how that would work, cause TEK Naturals would need to provide you with 1-2 weeks worth of TestoTEK to offer samples.
Yes, you’ll actually get a discount code pop-up on TEK Naturals’ website.
TestoTEK is definitely a decent testosterone booster. It might be a bit pricey compared to many other options on the market, but the 12 natural libido-enhancing, T-boosting ingredients make it worth it. There’s still room for a bit of improvement, but TEK Naturals seem trustworthy, and I expect them to deliver on that. Plus, the Autoship policy is really nice.
