Testogen Review: Is It Worth Your Money and Time?

The popularity of testosterone boosters has certainly skyrocketed in recent times. These supplements come with the promise of stimulating your own T production, thus making you manlier. One of the top dogs in this category is undoubtedly Testogen.

And in this authentic Testogen review you’ll find what it is, what it contains, how it works, what it did for me and more.

My Personal Experience with Testogen in Short

I’ve personally tried Testogen as I used an entire bottle and it simply delivers.

After around a week of taking this product, I started to notice some of the effects such as:

  • Rock-hard erections
  • Noticeably increased sex drive
  • Increased strength
  • Improve muscle saturation
  • A distinctive alpha male feeling

A quick look at its ingredient profile is enough to realize why this is one of the best testosterone-boosting supplements.

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!

And to make this Testogen review the most detailed and useful out there, in this article, I’ll cover relevant topics such as:

  • What Testogen is used for and who can benefit from it
  • The pros and cons of Testogen
  • My results and experience with Testogen
  • The ingredients and their effectiveness
  • Where to buy the original Testogen
  • Testogen side effects

TestoGen review, an open box containing 5 TestoGen bottlesQuick Overview of Testogen

  • Product: Testogen
  • Manufactured by: MuscleClub Limited
  • Price: $59.99 (FREE international shipping included)
  • Servings per container: 30 (120 capsules)
  • Guarantee: 100-day money-back (if you buy 2 or more bottles)
  • Testosteronerd’s rating: 5/5 (my all-time favorite T booster)

This is What Testogen is Used For

Testogen is a modern testosterone boosting supplement that’s used to naturally increase testosterone production in the body.

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.

Testosteronerd Recommends Testogen for Naturally Boosting T levels

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!


This is Who Can Really Benefit From Testogen

Any man who’s looking to optimize their testosterone in a natural manner can benefit from taking this product.

To make sure that no one feels left out, you might see great results from Testogen if you’re a man who:

  • Seeks to increase their testosterone levels naturally
  • Deals with low testosterone
  • Wants to make the most of their workout program
  • Suffers from low libido issues
  • Looks to gain control over their body fat levels
  • Wants 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, man showing thumbs up

The Pros of Testogen

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 weigh the pros and cons of this supplement.

Without further ado, the PROS 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, guy showing a thumbs down

The Cons of Testogen

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 CONS 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, before and after images

My Results from Taking Testogen for 1 Month

I’ve used this product to great success and it does what it promises.

I enjoyed firmer erections, greatly improved libido, increased drive, a more muscular look and decreased body fat.

All of this was achieved only by going through a single bottle! I can only imagine that these effects would compound even greater if you’re buying two or more bottles.

However, it’s worth noting that you should never expect steroid-like results from ANY supplement, period.

Although anabolic steroids yield superb results, it comes at the cost of your health.

While testosterone boosters (i.e. supplements) work by naturally increasing your own testosterone production.

This means they’re less potent but way safer as well.

After around 1 week I really started 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, this is what I noticed:

  • Rock-solid 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 body fat)
  • Noticeable determination for success
  • 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 official 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.

My sex drive and libido skyrocketed as I experienced some pretty amazing and fun erections that I last had when I was a teenager.

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 be wrong with you (or you have to be 14 year old).

TestoGen Review, a man jumping into the water

This Is What You’ll Most Likely Feel After Taking Testogen

Increased energy levels, improved libido + sex drive, enhanced muscle strength, more productive workouts and reduced body fat levels.

Notice that these are the things that you’re most likely to feel when taking this product!

No one can promise you that you’ll experience all of them.

But you can rest assured that you’ll at least feel some of the effects associated with having higher testosterone levels.

Since Testogen contains tested and proven ingredients, your natural T production is bound to increase.

Now, here are some of the most prominent effects related to elevated testosterone:

  • Increased muscle strength and mass
  • Higher sex drive and libido
  • Better and longer-lasting erections
  • More stamina and energy
  • Boost in confidence
  • Sharper concentration and focus
  • Decreased body fat

Basically, the more testosterone coursing through your veins the manlier you’ll feel.

We all want to feel young and full of energy and testosterone plays a vital role in this regard.

In fact, our natural testosterone production drops at roughly 1% every year once we hit 30.

And to reverse that, you have to focus on your lifestyle i.e. diet, training and supplementation with proven testosterone boosters like Testogen.

I Didn’t Feel Any Unwanted Reactions While Using Testogen

Using Testogen was smooth sailing for me as 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.

I’d say that Testogen is perfectly safe since apart from some increased aggression at times, I didn’t experience any actual side effects (e.g. nausea, vomiting or acne).

And the extreme horniness at times might be considered a plus but this depends on your relationship status as I personally didn’t fully enjoy this due to the fact that I have 2 kids at home.

So to put it short, I 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 list

Testogen Ingredients

Testogen contains 11 natural ingredients consisting of herbs, amino acids, plants, vitamins, minerals and extracts:

  • D-Aspartic Acid (DAA) – 2352 mg
  • Fenugreek Extract (Trigonella foenum graecum) (50% saponins)  – 40 mg
  • Korean Red Ginseng Extract (Panax Ginseng) – 40 mg
  • Magnesium (from Oxide and Citrate) – 200 mg
  • Vitamin K1 (from Phytonadione) – 20 mcg
  • Vitamin B6 (from Pyridoxal-5-Phosphate) – 20 mg
  • Vitamin D3 (Cholecalciferol) – 52 mcg
  • Nettle Leaf Extract 4:1 (Urtica dioica) – 40 mg
  • Zinc (from Citrate Dihydrate) – 10 mg
  • Boron (from Citrate) – 8 mg
  • Black Pepper Extract (95% piperine)(Bioperine) – 5 mg

What makes this product so effective is the fact that all the ingredients are scientifically validated, which means that they’re proven by science.

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:

1. D-Aspartic Acid (Boosts T by 20%)

TestoGen review, ingredients - D-Aspartic acid, cheese
There’s plenty of DAA to be found in dairy products like cheese!

Dose per serving: 2352 mg

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

This HAS to be the most used substance 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?

2. Fenugreek (Boosts T by 46%)

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.

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 is dosed at 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…

3. Korean Red Ginseng Extract

TestoGen review, Ginseng

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!

4. Magnesium (boosts T by 25%)

TestoGen review, ingredients - Magnesium - avocado
Want more Magnesium in your diet? Eat avocados!

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.

5. Vitamin K1

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!

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.

6. Vitamin B6

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

7. Vitamin D3 (Boosts T by 20%)

TestoGen review, sunshine - Vitamin D
Sunshine is naturally what triggers Vitamin D synthesis.

Dose per serving: 52 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 is 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).

The 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?

8. Nettle Leaf Extract

TestoGen review, ingredients - Stinging Nettle leaf extract
Be careful if you touch these leaves – they sting!

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!

9. Zinc (Boosts T by 92.8%)

TestoGen review, ingredients - Zinc - Red meat
Red meat and Zinc content go hand in hand.

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.

10. Boron

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 (7 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!

11. Bioperine

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 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.

TestoGen review, a box and 3 bottles of TestoGen

This is Where to Buy the Original Testogen From

The only genuine place from which you can buy this product is the official Testogen website.

By doing so you ensure that one bottle will cost you exactly $59.99 (there’s a $10 discount), it will last you an entire month and you’ll also benefit from massive multi-buy savings.

As for its availability on Amazon, you’ll most likely find it there offered by an unauthorized seller.

The reason for not authorizing any third-party stores is quite simple.

The company that manufactures Testogen (Muscle Club Limited) wants its product to be of unprecedented quality – every single bottle that’s shipped worldwide.

As a result, they haven’t authorized any retail stores or supplement shops to sell their popular T booster.

That’s why my personal advice would always be to always buy Testogen from the original source.

4 Reasons to Never Buy Testogen from Third-Party Sellers!

Here are 4 very valid reasons for buying Testogen only from the real source:

1. The Product Might Be Fake (Not Genuine)

This is a very likely scenario if you’re getting your Testogen from third-party sellers.

By doing so, you’ll have absolutely no idea if what you’ve ordered is what you’re expecting to get.

It might be a counterfeit product or a supplement that has nothing to do with boosting your testosterone in a natural way.

2. You Lose Access To The Related Discounts

By opting to buy your Testogen from an authorized seller, you won’t be able to take advantage of the official discounts for this product.

Subsequently, you’ll be paying more.

Also, you won’t be getting any stuff for free e.g. extra bottles or other goodies.

3. There Is No Money-Back Guarantee

Yep, buying this testosterone booster illegally means that you can’t use the official money-back guarantee.

So even if you’re unhappy with this product for whatever reason or you just want to return it, you’ll have to suck it up and move on.

That’s the price you pay for going the unauthorized way.

4. You’ll Most Likely Get Charged For Shipping

By trying to play it smart (or so you think).

Or to put it short – by not ordering this product via the genuine website, you’re exposing yourself to extra shipping fees.

The shipping for Testogen is completely free if you get it through the original source.

However, that’s not the case with 3rd-party retailers.

TestoGen review, does GNC sell TestoGen, question
By Raysonho @ Open Grid Scheduler / Grid Engine – Own work, CC0,

Does GNC Sell Testogen?

GNC doesn’t sell Testogen and this product has never been part of their portfolio.

In fact, you won’t find genuine Testogen products in any of the highly popular online retailers like Amazon, Walmart, GNC etc.

But if you do find it listed on any of these places, remember that this is most likely someone reselling this supplement.

Although I’ll have to repeat myself, I think that it’d be justified as this is really important:

Pro tip: DO NOT buy Testogen from ANY third-party source, other than the official site!

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

TestoGen review, TestoGen works banner

Testogen Side Effects

Testogen is considered a safe product that shouldn’t usually cause any adverse reactions.

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.

TestoGen Review, jacked man posing and flexing

These are the Potential Side Effects of Testogen’s Ingredients

Potentially and generally speaking you might experience things like increased nervousness, headaches, irritability, acne and even aggression.

However, it’s highly unlikely that you’ll encounter ANY of these adverse reactions!

That’s because the ingredients in this supplement are dosed correctly and some are even underdosed.

Still, let’s take a look at some of the ingredients that have higher doses:

1. Vitamin B6 (Pyridoxine) – 20 mg (1428% of normal daily values)

The fact that Testogen uses a dose that’s 1428% greater than the nutrient reference values (i.e. daily values) for Vit B6 might seem frightening, sure.

But it shouldn’t be! Relevant research shows that the safe upper limit for Vitamin B6 supplementation is 100 mg (13).

This is FIVE times more than what’s inside Testogen so stop worrying.

Vitamin B6 can cause neuropathy at doses of 1000 mg daily – now compare that to the mere 20 mg dose here!

The same study also points out that occasional toxicity might occur at doses between 100 and 300 mg per day.

In this regard, this supplement is as safe as they get, as you’ll be well within the safe range for this vitamin.

Nonetheless, here’s what you might expect if you take too much Vit B6 (over 100 mg or more likely over 1000):

  • Diarrhea
  • Nausea
  • Stomach
  • Cramps
  • Vomiting
  • Headaches
  • Sleepiness

Anyhow, B vitamins are water-soluble, meaning they dissolve in water and as a result, your body doesn’t store them.

2. Vitamin D3 (Cholecalciferol) – 50 mcg (1000% of normal daily values)

Again, don’t let the three-digit numbers here freak you out.

It’s widely accepted that Vitamin D doses of around 4000 UI (100 mcg) are safe.

In fact, studies show that doses of up to 10000 UI (250 mcg) didn’t show any toxicity in healthy individuals (14).

This means that you need well over 50 mcg of this vitamin to even remotely experience any side effects.

And such side effects are the direct result of calcium buildup in the bloodstream, due to massive amounts of Vitamin D in the body.

The scientific name for this condition is hypercalcemia (15) and it can potentially lead to certain unpleasant reactions such as:

  • Vomiting
  • Nausea
  • Weakness
  • Diarrhea
  • Constipation

Still, the dose presented in Testogen is far from being excessive so you should be fine.

3. Zinc – 10 mg (100% of normal daily values)

Okay, okay I know that this is the optimal Zinc dosage per day according to the nutrient reference values (NRV).

Regardless, I still wanted to tackle Zinc as some folks might be afraid of not overdosing with it.

I’m here to tell you that 10 mg of Zinc won’t kill you, especially since the upper intake level or UL for this mineral is 40 mg/day.

Anyway, if you ever decide to go overboard with Zinc supplementation (e.g. doses over 150 or even 100 mg), here’s what you might encounter:

  • Vomiting
  • Metallic taste
  • Nausea
  • Diarrhea

On a side note, one particular study found that 150 mg Zinc per day over 6 weeks may cause vomiting (16).

In fact, more than half of the test subjects in this research experienced vomiting with this dose.

But 150 mg is like 15 times more than the amount of Zinc found in Testogen, so you’ll be well and alive.

Other Key Testogen Facts to Consider

Below I’ve compiled a few important facts about Testogen that you might want to keep in mind:

1. Testogen is not an Anabolic Steroid

Testogen is a natural supplement and it has absolutely NOTHING to do with anabolic steroids.

Testogen is a natural product i.e. a supplement and it doesn’t contain anything illegal or banned.

Sure, it may not be as effective as anabolic steroids, but it won’t cause your own T production to shut down.

It will increase your testosterone by stimulating your body to produce more of it, unlike steroids.

You see, anabolic steroids i.e. synthetic testosterone simply replace your natural T with some synthetic crap.

And by receiving x10 times the testosterone of a normal male your body simply stops producing this hormone altogether.

So not only will your balls shrink, but you’ll also have the “privilege” to potentially experience the wide array of side effects related to using steroids.

I’ll pass, thanks.

2. Testogen is FDA Approved

Testogen is manufactured in FDA-approved facilities, which means that it needs FDA’s manufacturing standards.

It also contains natural ingredients only, hence its ‘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.

3. Testogen is not a Scam Product

Testogen is a 100% legit testosterone-boosting supplement that works according to the majority of reviews (including mine).

7 Bulletproof Reasons Why Testogen is Totally Legit!

Now, let’s have a look at some bulletproof reasons as to why Testogen is totally legit and why it’s NOT a scam product.

1. This Testosterone Booster Doesn’t Hide Behind Proprietary Blends

TestoGen review, different capsules and pills

Testogen’s ingredient profile is 100% transparent and fully disclosed on the back of each bottle.

Thus, you know the precise amount of each ingredient that you’re getting per serving.

To me, this means one thing – the manufacturer has nothing to hide.

It’s quite modern for T boosters and other supplements to have the so-called ‘proprietary blend’.

This term stands for a non-transparent ingredient label.

Or in short, you’re only shown the total amount of all ingredients in grams or milligrams.

With Testogen you know the exact amount (per serving) of every single ingredient listed. Talk about transparency!

This can be quite problematic as you have virtually no idea exactly how much you’re getting from ingredient X and ingredient Y.

For example, only one of the ingredients may be adequately dosed, while all the other ones are underdosed.

You can never really know.

2. It Relies on Scientifically-Validated Ingredients Only

The unique formula of this product consists of 11 tested and proven ingredients that are backed by science.

Each of these ingredients works in a direct or indirect way for two primary reasons:

  1. To stimulate your testosterone production
  2. To enhance your libido.

Also, the formulation utilizes some clever features to make the big hitters like D-Aspartic Acid, Fenugreek and Red Ginseng even more effective.

This is especially true when it comes to the Bioperine extract included in the formula.

Bioperine is a patented black pepper extract that increases the absorption rates of other ingredients (17).

This means that your body will be able to absorb more of the key ingredients. And that’s crucial.

Who cares if you’re getting optimal doses if your body cannot absorb them.

3. There Are No Banned or Illegal Substances in Testogen

TestoGen review, a lot of syringes

Another reason that proves this product’s genuineness is the fact that it’s free of any harmful substances.

This means nothing banned or illegal such as anabolic steroids.

It utilizes only natural compounds, nothing else.

Testogen is free of any fillers, preservatives and banned or illegal substances!

Sure, some people might automatically assume that this is the case with every other supplement out there.

That’s what US swimmer Jessica Hardy assumed before the 2008 Olympics.

She started taking a muscle-building supplement prior to the event.

Long story short, she got banned because they found Clenbuterol in her system.

And In case you didn’t know, Clenbuterol is on WADA’s list of banned substances i.e. World Anti-Doping Agency prohibited list.

Eventually, the Court of Arbitration for Sport dismissed her 1-year ban issued by WADA so Mrs.

Hardy’s situation wasn’t all bad.

But it just shows how important using a banned substance-free supplement is.

4. There Are No Known Or Reported Side Effects

While I was on Testogen I didn’t experience any adverse reactions and that seems to be the rule, not the exception.

After going over various online reviews I realized that I wasn’t an isolated case.

Testogen is indeed perfectly safe and virtually side-effect-free.

So if you’re concerned about any potential side effects – don’t be.

This supplement is totally safe to use. It doesn’t contain anything harmful or particular compounds that result in more frequent side effects.

Still, if you’re overly curious – some potential side effects of Testogen might include:

  • Irritability
  • Nervousness
  • Aggression
  • Headaches

But it’s extremely unlikely that you’ll feel any of these or any adverse effects at all for that matter.

It’s all smooth sailing while taking Testogen so relax.

I’m yet to come across someone who felt unwanted and unpleasant reactions to this product.

5. Almost All Of The Testogen Reviews And Client Feedback Are Positive

Indeed – it’s almost impossible to stumble upon a negative review of Testogen.

In fact, I challenge you to show me one.

I’ve been trying to find a review or just some client feedback that bashes the product and I couldn’t find any.

This can mean only two things.

Either Testogen is truly a sensational testosterone booster or everyone is paid to endorse this supplement.

While there’s no doubt that option 2 is valid, it’s still impossible for everyone to be THAT biased.

Thus, it’s safe to say that Testogen simply works and men are genuinely happy with the results. Including me.

6. There’s an Iron-Clad Money-Back Guarantee

That’s right, the manufacturer is so confident in their product that they’re willing to offer you a complete refund if for some reason you’re unhappy with Testogen.

You can request a 100% refund within 100 days of receiving your order.

Once you’ve sent an email to their support, the manufacturer will assess your claim within 24 hours!

All you have to do is let them know what didn’t work for you and you’ll be 100% refused, although this excludes a 15 fixed claim fee that’s there for admin and shipping costs.

Another great thing is that they’ve updated their refund policy, so now there’s no need to send any unused Testogen bottles back to the manufacturer.

However, this 100-day money-back guarantee is only applicable if you buy a 3 or 5-month supply.

Additionally, you can use their refund policy only once.

Nonetheless, I highly doubt you’ll ever need to use their money-back guarantee.

Why? Because you’ll love the results!

7. Testogen Is Manufactured In FDA-Approved Facilities

TestoGen review, scientist in a laboratory

Testogen not only relies on high-quality ingredients, but it also utilizes cutting-edge manufacturing practices.

More specifically, this T booster is made in FDA-approved facilities on US soil.

Apparently, the company that manufactures this supplement is all about quality.

They don’t cut corners when it comes to creating supplements of the highest quality.

And it shows since their Testogen continues to help men across all ages throughout the globe.

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?
