TestoGen Review [2021]: Boost your T by 203%!? My Results

Gaining an advantage in the hunt for more natural testosterone is a tricky task. You can adjust your nutrition, sleep, and exercises accordingly in order to optimize your masculinity, but there’s more to it. Apart from challenging Anthony Joshua to a boxing match (it might be counterproductive though), there are other ways that could boost your T and my TestoGen review will help you in that direction!

Click Here to Try TestoGen Risk-Free for 100 Days!

I’ve tried TestoGen personally and to be perfectly honest with you, it simply delivers.

This supplement is definitely one of the best (the best in my opinion) testosterone boosters out there, without a shadow of a doubt.

Not only did it made me feel more like an alpha male, but it also boosted my libido.

All of this on top of being stronger and looking more defined (due to a decreased body fat percentage).

Even a quick look at its ingredient profile is enough to cement its place among the very best products in this category.

FORMULA UPDATE: TestoGen’s formula has been updated and as a result, it’s now vastly improved to deliver even better results!

GUARANTEE UPDATE: TestoGen now boasts an industry-leading 100-day money-back guarantee!

It now features new ingredients, more absorbable versions of the older ones, while some ingredients like Tribulus (which is useless) were removed!

It’s been on the market for a few years now and its reputation is rather stunning. So hey, let’s dive into the action… NOW!

What Exactly Is TestoGen?

TestoGen is a modern testosterone boosting supplement that’s designed to naturally increase your T production.

It has nothing to do with anabolic steroids and there’s nothing banned inside!

Truth be told, I’m personally skeptical towards testosterone boosters having too many bells and whistles these days.

If anything sounds too good to be true, be SURE that it damn is!

When a supplement promises you Mr. Olympia-kind of gains, Arnold’s deep voice or beard that can cut through diamonds, it’s just a bit too much.

Let’s cut to the chase now and take a look at what Testogen has in store for us, according to the manufacturer:

  • Improved muscle mass
  • Increased strength levels
  • Boosted libido
  • Enhanced performance (mentally and physically)
  • Lower body fat (mainly around your waistline)
  • A potential reduction in cholesterol levels and lower blood pressure

On paper, this sounds amazing, stunning, breath-taking.

In a minute I’ll share my own take on whether there’s any truth to these claims.

For now, we can just conclude that this one has a lot to prove!

TestoGen review, two TestoGen bottles

How Good Is TestoGen?

It’s REALLY good and it does what it promises – to increase your natural testosterone production.

TestoGen is one of the top and best-selling testosterone boosters out there for a reason.

It contains a total of 11 science-backed ingredients that are meant to naturally stimulate your testosterone production.

I’m personally a huge fan of it as I went through 2 bottles of this stuff and fell in love with it.

There are also no banned or harmful substances in this product.

So if you’re an athlete or someone who competes – you can use TestoGen without any issues whatsoever.

It’s safe, effective and affordable. Honestly, what’s not to like about this testosterone booster?

Now it’s time to check who is a fit candidate for TestoGen, rock on!

Who Can Benefit From TestoGen?

Anyone who’s looking to optimize their manhood in a natural manner.

To make sure that no one feels left out, let me give you a quick list of the guys who can utilize TestoGen:

  • Men seeking to increase their testosterone levels naturally
  • Men dealing with low testosterone
  • Men who want to make the most of their workout program
  • Men with libido issues
  • Men looking to gain control over their body fat levels
  • Men who’d like to reach that ‘alpha male’ status

Now, although it very well may help with you decreasing your BF percentage, I’m not implying that this T-booster is a fat burner.

The main point here is that the more fat you carry, the more estrogen you are going to have.

Increasing your testosterone can reverse that by helping you burn more fat.

Also, TestoGen is a supplement and as you probably know, supplements are OTC (over-the-counter) products.

They’re safe and they are NOT anabolic steroids. If you’re still bewildered, take a look at my article related to the safety aspect of testosterone boosting supplements.

And please, don’t mistake this TestoGen for Ronnie Coleman’s Testogen-XR, which is an entirely different animal (although it also contains D-Aspartic Acid).

Know what? It’s that time again – the time for me to lift up the curtain and share my OWN experience with TestoGen, with YOU guys!

TestoGen review, before and after images

My Personal Experience With TestoGen

Overall, I was in awe with this testosterone booster! It took around a week to really start noticing the effects of TestoGen.

This includes positive changes in both appearance and attitude, which I attribute to the increased testosterone levels that I had.

And I also can’t neglect the fact that TestoGen now comes with a new and improved formula that’s bound to optimize your testosterone levels even further!

And while I didn’t become the new Incredible Hulk (who expects that from a supplement, really), these are the things that are worth mentioning:

  • Superb erections (some of my all-time best)
  • Libido and sex drive through the roof
  • More strength (I was able to lift heavier)
  • Less body fat
  • More muscle definition (as a result of less BF)
  • Determination for success (directly correlated to higher testosterone levels)
  • Alpha male attitude

One of the things that put the biggest smile on my face as a result of being on TestoGen was actually looking better naked.

As summer is approaching faster than ever, the timing just couldn’t have been better for me!

Aside from that, less fat means there was less of it to be turned into estrogen by the aromatase enzyme, so hooray for that.

And fat comes with the “bonus” of having the aromatase enzyme, which helps to convert testosterone to estrogen.

As for my dosing protocol, I followed the directions on the bottle – 4 capsules per day.

Logically, each bottle (I did two bottles, back to back) lasted me exactly 30 days.

I chugged down the whole 4 caps dose all at once, but you’re free to spread the doses throughout the day if that suits you.

You know what the Hodge twins say – “you can do whatever the F#%& you wanna do

My Sex Drive And Libido Skyrocketed!

But boy, oh boy, the true beauty of TestoGen could very well be its libido-boosting capabilities!

I mean, I haven’t had such dense, rock-solid erections since I was 14 perhaps (I’m married, so I’m not afraid to admit it… no shame whatsoever).

Honestly, guys, if you don’t share similar results, something has to wrong with you (or you have to be 14 yo).

Did I Encounter Any Unwanted Reactions While Using TestoGen?

As a whole – no. I didn’t experience headaches, nausea, vomiting or anything like that.

It was pretty much smooth sailing with the only exception of two supposedly negative aspects:

  • Excessive aggression
  • Too much horniness

Both of these are completely controllable so don’t panic! In terms of excessive aggression, don’t think of it as a sort of uncontrollable rage or bloodlust.

It’s just that when something (or someone) pushed my buttons too much, I had a tiny bit more aggression at my disposal.

Nonetheless, while I was more aggressive than usual – no one was hurt during the use of this product.

And the extreme horniness at times might be considered a plus, depending on your relationship status.

I personally didn’t enjoy this all that much as I’m married and have 2 kids.

So to put it short, me and my wife don’t have an awful lot of free time on our hands so this can get rather frustrating!

Now, I’ll get into MORE detail about ‘the good’ and ‘the bad’ of TestoGen further down this review.

But for now, as you already have a sense of my positive vibe towards it, maybe it’s a good idea to check the formulation behind this testosterone booster? Come on!

As you can see, TestoGen contains 11 natural ingredients with proven testosterone and libido-boosting track record!

TestoGen review, ingredient profile

As you can see, TestoGen contains 11 natural ingredients with proven testosterone and libido-boosting track record!

TestoGen’s Ingredient Profile

This is TestoGen’s primary weapon – its outstanding formula.

As evident in my TestoGen ingredients article, all 11 herbal extracts and compounds in this product are scientifically-validated.

This means one thing – this testosterone booster delivers!

  • D-Aspartic Acid (DAA) — 2352 mg
  • Fenugreek Extract 4:1 — 40 mg
  • Ginseng Extract — 40 mg
  • Magnesium — 200 mg
  • Vitamin K1 — 20 mcg
  • Vitamin B6 — 20 mg
  • Vitamin D3 — 50 mcg
  • Nettle Leaf Extract — 40 mg
  • Zinc (Citrate) — 10 mg
  • Boron — 20 mg
  • Bioperine — 5 mg

And It’s plain as day that TestoGen means real business if you just glance at the ingredient label.

Every ingredient is proven, solid and dosed accordingly – there’s not much room for criticism here.

120 capsules, 30 servings, full month supply. Let’s put our scientific glasses and dive deeper into the formula of TestoGen:

TestoGen review, ingredients - D-Aspartic acid, cheese

There’s plenty of DAA to be found in dairy products like cheese!

D-Aspartic Acid (Boosts T by 20%)

Dose per serving: 2352 mg

Is there anyone out there that’s not familiar with DAA, honestly?

This HAS to be the most used substances in T boosting supplements.

There’s a good reason for that folks – I personally adore it as D-Aspartic Acid does play an active role in both the production and regulation of testosterone in men.

Here in TestoGen, it comes at a neat 2352 mg dose per serving, which is superb.

Studies show that DAA can increase testosterone by up to 5-10% in healthy men and up to 20% in guys with lower T levels (1)!

It’s been proven to play a vital role in the synthesis of testosterone and LH (luteinizing hormone).

I’ve covered this amino acid more in-depth in my ‘What is in a testosterone booster‘ article.

Oh, just in case – the main perk of DAA is its ability to help turn cholesterol into testosterone. Cool, eh?

TestoGen review, ingredients - Fenugreek seed extract

These are Fenugreek seeds in raw form, before they become the extract that you find in testosterone boosters like TestoGen.

Fenugreek (Boosts T by 46%)

Dose per serving: 200 mg

This plant has a weird name, but it’s not Greek, really!

However, it HAS to be one of the most potent ingredients to give your manliness a boost to date.

The Fenugreek extract from the seeds of the plant, are 200mg here, which is more than many other testosterone boosters on the market.

Science is conclusive – supplementing with Fenugreek not only boosts testosterone levels by 46%, but it also has a positive impact on libido (2)!

As a matter of fact, this little fellow has libido-enhancing properties as well.

So in addition to giving your natural T a lift, you could benefit from more oomph below your belly, if you catch my drift…

TestoGen review, Ginseng

Red Ginseng Extract

Dose per serving: 250 mg

Eastern cultures know a thing or two about natural remedies to low T or just something to spark your sex life.

In this regard, the guys behind TestoGen decided to add a hefty 250mgs of Panax Ginseng (root extract).

And guys, this is the sh!t when it comes to different variations of ginseng.

Researchers claim that red (Asian) Ginseng may be a superb natural treatment for erectile dysfunction (ED) (3).

Hailing from Korea, this plant is known as the ‘man root’ for a reason!

And it seems that Ginseng also plays a major role in the function of androgen receptors, thus helping with testosterone production (4).

Ginseng safeguards your nuts from dioxins which in return means improved libido with some rock-solid erections.

Overall it’s a tool to deliver the goods in terms of more stamina, energy, virility etc… the lot!

TestoGen review, ingredients - Magnesium - avocado

Want more Magnesium in your diet? Eat avocados!

Magnesium (boosts T by 25%)

Dose per serving: 200 mg

This is the first brand new addition to TestoGen’s formula and it’s a must-have for every great T booster.

Magnesium is a vital mineral that plays a crucial role in the creation of our favorite hormone and it also promotes better sleep.

But as far as testosterone goes, a relevant study from 2011 found that individuals who supplement with Magnesium and work out, experience an increase in their free testosterone by almost 25% (5)!

Not only that but Magnesium also plays a role in neuromuscular transmission and muscle contraction, making it a viable anti-muscle cramp tool.

TestoGen review, Vitamin K - green leafy vegetables

Green leafy veggies are what you’re looking for if you want more Vitamin K in your diet!

Vitamin K1

Dose per serving: 20 mcg

This is a water-soluble vitamin that provides a plethora of benefits.

Apart from helping with blood clotting, Vitamin K1 is also responsible for maintaining healthy bone tissue and even teeth.

All of these goodies are due to Vitamin K1 transporting Calcium to your teeth and bones.

Relevant studies have found that Vitamin K1 and Vitamin D work brilliantly together, thus amplifying Vitamin D’s testosterone-boosting capabilities (6).

But also, this vitamin works in synergy with Vitamin D (it actually increases its absorption rates), thus providing an even more powerful T-enhancing effect.

TestoGen review, ingredients - chickpeas - Vitamin B6

Apart from poultry, fish and wholegrain cereals, chickpeas also contain plenty of Vitamin B6.

Vitamin B6

Dose per serving: 20 mg

Can’t go wrong with the addition of any vitamin from the B group, especially B6.

Many manufacturers are accepting this idea and it’s a common sight to see a T booster with B vitamins in it.

Science shows that in combination with Magnesium and Zinc (TestoGen contains both), Vitamin B6 is able to boost serum testosterone levels (7). This combo is also known as ZMA (Zinc, Magnesium and Vit B6).

TestoGen is boat loaded with B6 and that’s absolutely brilliant.

B6 is involved in more than 100 unique processes in the body.

Plus it also aids in the assimilation of amino acids by your system and even helps with testosterone production.

TestoGen review, sunshine - Vitamin D

Sunshine is naturally what triggers Vitamin D synthesis.

Vitamin D3 (Boosts T by 20%)

Dose per serving: 50 mcg

Sunshine is naturally what triggers Vitamin D synthesis

If you live somewhere in the cold north, where enjoying the sunshine is as rare as a decent song by JB (you know who I’m referring to), then I’ve got some BAD news for you bro!

Vitamin D synthesized when your skin is directly exposed to sunlight. What does that mean?

If you live in a region with crap weather (it’s ok, I won’t be mentioning anything specific), chances are you could very well be Vit D deficient.

Vitamin D supplementation has been shown to have a positive impact on free and total testosterone levels, while also improving erectile dysfunction symptoms (8).

Good news is that TestoGen offers Vitamin D as part of its formula, so you’re in safe hands.

Other research shows that men who supplemented with Vit D3 for 1 year experienced a 20% increase in their testosterone levels (8.1)!

And I guess there’s no need to mention that this AWESOME vitamin plays a role in testosterone production?

TestoGen review, ingredients - Stinging Nettle leaf extract

Be careful if you touch these leafs – they sting!

Nettle Leaf Extract

Dose per serving: 40 mg

This plant is known to be a potent diuretic since ancient times.

It also helps with urinary problems (logically), while also being a potent tool against osteoarthritis and joint pain in general.

Stinging nettle is a superb T-boosting ingredient due to its SHGB (sex hormone-binding globulin) binding properties, according to research (9). This means that you’ll have less “bound” and more active testosterone in your body!

Now, testosterone tends to bind to this protein, which makes T less potent as a result.

But when the nettle leaf extract binds to SHGB, it actually leaves more testosterone in its free form.

This, in turn, means that more testosterone will flow through your bloodstream freely, while you enjoy all the benefits of increased testosterone levels!

TestoGen review, ingredients - Zinc - Red meat

Red meat and Zinc content go hand in hand.

Zinc (Boosts T by 92.8%)

Dose per serving: 10 mg

Yet another staple amongst an awful lot of similar products.

For the 1000th time, it’s worth mentioning that Zinc is actually a PROVEN testosterone-boosting ingredient, according to relevant scientific data.

Zinc will not only improve your natural T production, but it will boost your sperm count too, according to studies (10)!

And the pretty cool 10 mg dose of Zinc found in TestoGen is awesome, as it provides 100% of the recommended daily intake for this mineral.

Another study shows more spectacular results as elderly men who were slightly deficient in Zinc saw an almost 93% increase in their testosterone levels after taking Zinc for 6 months (10.1).

It also comes in Citrate, which is a more absorbable version compared to other Zinc forms.

TestoGen review, ingredients - Boron - apples

Apples are a great way to add more Boron to your diet.


Dose per serving: 8 mg

Boron is a trace mineral that can be found either in the soil or in particular fruits and veggies.

You might be wondering what does this mineral has to do with testosterone, but it actually has A LOT to do with it!

According to studies, taking 10 mg of Boron over the course of one week (seven days) leads to a 28% increase in testosterone levels, while also lowering estrogen by 39% (11)!

Essentially, Boron not only boosts your testosterone levels – it even decreases your estrogen at the same time!

TestoGen review, ingredients - Bioperine - black pepper extract

Bioperine is basically a highly-concentrated black pepper extract.


Dose per serving: 5 mg

In essence, this is a black pepper extract.

While it doesn’t directly boost male hormone levels, what it does is it increases the absorption rates of all other ingredients that are part of TestoGen’s formula.

The active ingredient of Bioperine – piperine has been scientifically-validated to increase the bioavailability (absorption rates) of other ingredients (12).

And that’s great news since Bioperine essentially makes every single ingredient in this product more effective and more potent, leading to better results for you.

Does GNC Sell TestoGen?

No, it doesn’t. In fact, you won’t find TestoGen in any of the highly popular online retailers like Amazon, Walmart, GNC etc.

The only place online where you can buy this product from in a legit way is through the official TestoGen website.


Because the manufacturer of this supplement wants to ensure the optimal quality, purity and authenticity of TestoGen. Here’s what you get by buying from the genuine site:

  • The real thing i.e. the original TestoGen
  • Free shipping worldwide
  • Top-notch customer support
  • Great deals and offers

I’ve covered TestoGen where to buy in more detail in a separate article, but I still want to point something out.

DO NOT buy this testosterone booster from ANY place, other than the official source!

Otherwise, you lose access to all of the aforementioned perks and above all, you’re buying something potentially shady.

Is TestoGen FDA Approved?

Yes, because TestoGen is manufactured in FDA-approved facilities.

It also contains natural ingredients only, hence it’s ‘dietary supplement’ status.

And TestoGen is also free of any harmful and/or illegal substances i.e. anabolic steroids.

So overall, this is a perfectly safe and pure product that’s manufactured to FDA standards.

TestoGen review, bottle of TestoGen held in a hand

TestoGen Side Effects – Does It Have Any?

Generally, no – this is a safe product that shouldn’t cause any adverse reactions.

As evident in my TestoGen side effects post, it’s highly unlikely that you’ll encounter any side effects with this T booster.

First and foremost, none of the ingredients are too highly dosed in any way that may trigger an unwanted reaction in your body.

And second, the only real side effects that you’ll possibly encounter would probably be related to having your testosterone levels increased as a result of taking TestoGen.

This is what I personally felt while I was on TestoGen in terms of side effects:

  • Excessive aggression
  • Excessive horniness

It wasn’t anything too crazy, but it was noticeable.

And guess what?

Both of these can be attributed to increased T levels.

So it’s somehow justified to come across such side effects while being on TestoGen.

As for other potential adverse reactions, some ingredients may lead to nausea, diarrhea and vomiting.

The keyword here is “may” as you’d need to take A LOT of e.g. Zinc to cause any of that.

But like I said, the ingredients in TestoGen aren’t dosed too high so you should be perfectly fine.

Pricing and Special Offers

TestoGen review, thumbs upTestoGen – The Good

I can say a lot of good things about TestoGen. It’s safe, natural and it works.

But don’t worry, we’ll also get to the cons of this product in a bit.

Keep in mind that I have personal experience using this one, so I’m confident in how I weight the pros and cons of this supplement.

Without further ado, the GOOD of TestoGen:

  • No proprietary blends – you see the exact amount of each ingredient
  • Natural and safe to use – nothing banned or illegal inside
  • International shipping
  • Proven and efficient ingredient profile
  • One bottle lasts you the whole month
  • Super-fast delivery and awesome customer support
  • Small caps, no problem to swallow
  • 60-day guarantee (only when you buy 2 or more bottles though)
  • Decently priced

These are the things that impressed me the most so I decided to include them under my ‘The Good’ section.

I should point out that delivery was super fast – arrived at my address after just a few days and it generally takes longer with other stuff I purchase online.

Can you conclude that TestoGen is flawless then?

Of course not. Not even Megan Fox is flawless!

TestoGen review, thumbs down

TestoGen – The Bad

There are two sides to every coin – this is when we turn out attention to the uglier one (do coins have ugly sides?).

This booster is fabulous, hands down, but I’m obliged to share the unpleasant side with you guys – that’s how Testosterone Nerd rolls!

Ready for the BAD of TestoGen? Here we go:

  • The guarantee only applies if you order two or more bottles (there are T boosters with better guarantee conditions out there)
  • Can’t buy in a supplement store – you can only order it from the official TestoGen website
  • It’s leaning towards the expensive side of testosterone boosters

It’s all about increasing the natural output of our primary male hormone and if it does the trick, I wouldn’t mind having something with a dubious reputation.

If it doesn’t negatively affect my health in any way, shape or form, then I’m all good.

Alright, I’m about to bring down my judge’s gravel (I don’t work in a court, chill)!

TestoGen review, judge gavel

Final Verdict

Would I conclude this review with a happy end, or would TestoGen suffer T.N.’s renounce?

With a hand on my heart, I’m glad to announce that TestoGen delivers.

It’s certainly a top contender for the best testosterone boosting supplement title!

Without being too picky or judgemental (who am I to judge anyone/anything though, only God can), this is one fine product for any guy looking to give his manhood a well-deserved lift.

Can I guarantee you the same results that I had?

Not, by any stretch of the imagination!

Get yourself a bottle and only then can you compare your experience to mine – we’re all different and our bodies (obviously) are too.

I’m just sharing my intake with you guys on the internet.

My intention is to put out valuable reviews (this is a review after all) with no added bullcrap and with 100% honesty.

Get TestoGen Now & Feel Real Results Yourself!

So, TestoGen is legit. It’s a legit supplement designed to enhance one’s masculinity.

Would it increase yours?

I wish I could tell you, but you’re the only one that could answer this question – you!

I genuinely hope that you found this quite detailed TestoGen new formula review helpful.

Now, tell me about your OWN experience with TestoGen – did it deliver… or no?

I've been fascinated by natural male hormone optimization since 2016. And ever since I've been going through boatloads of different meta-analyses and scientific data associated with increasing testosterone levels naturally. Currently, I'm working on my Ph.D. dissertation titled 'The Informed Choice of Dietary Supplements as a Problem of Health Literacy and Health Promotion". Thus, in my collective work on this site you'll find helpful tricks, natural remedies, detailed product reviews (including stuff I've personally tried) and more!
