  • A little expensive (but 20% discount on the official website)

TestoGen is a really decent testosterone booster for both athletes and the average gym goer.

The efficiency of the ingredients (courtesy of the new improved formula) found in TestoGen are backed by science, the positive effects it has on your physical and mental development are more than real, and there are barely any side effects to worry about (as long as you don’t mix TestoGen with other supplements, of course). 

True, the price isn’t extremely appealing, but the quality more than makes up for it.

TestoGen has been hyped as being the best testosterone supplement on the market. What’s more, it’s also advertised as being completely natural.

Well, I decided to check out this supplement, and share my findings with you guys. I’ve combed the web for customer opinions, studies, and other sources of info to see if TestoGen is really as amazing as everyone says it is.

At a Glance

  • Who makes TestoGen? Well, the company behind TestoGen is called Wolfson Berg Limited, and they’re apparently quite well known as being trustworthy, and offering safe, quality supplements.
  • TestoGen is basically a testosterone supplement that boosts muscle and strength gain, and can also help you increase your stamina and mental fortitude. The premise essentially is that, with this supplement, you can train harder and longer, and recover faster.
  • While the supplement can be used to address issues that come with age (low libido, inability to focus, and so on), it should be noted that TestoGen does not work as an anti-age supplement.

Who Is TestoGen Right for?

The great thing about this supplement is that there aren’t any restrictions that can keep the average man from taking advantage of it. As long as you are over 18 years old, you can take TestoGen.

Of course, that doesn’t mean TestoGen isn’t ideal for athletes or gym buffs. In fact, given its huge efficiency when it comes to muscle and strength development, I highly recommend people like that use TestoGen to enhance their results.

How Does TestoGen Work?

TestoGen uses natural ingredients exclusively to help men combat decreasing testosterone levels (it’s not something one can easily stop, as our T levels tend to take a hit when we reach 20 years, and keeps going down afterwards).

The main way it accomplishes that is by targeting free testosterone levels, and increasing them. What is free testosterone? Just think of it as testosterone that’s in your bloodstream but isn’t attached to any proteins and it’s just free-floating.

As a result of all that, people who take TestoGen tend to experience:

  • Restored vitality
  • Enhanced strength and muscle development
  • Increased stamina 
  • Better mental capacity 
  • Increased libido 

All in all, this supplement is meant to rejuvenate your body. Obviously, it won’t keep you from getting old (wouldn’t that be something?), but it can help you feel (this is the key word here) young - even if you’re “past your prime” like some people would say.

TestoGen Ingredients - What’s in It?

testogen new formula label

One of TestoGen’s main selling points is that it’s completely natural. Well, I’m happy to say that’s no exaggeration. I went over the ingredients found in the supplement and researched them in-depth - they’re truly legit.

Plus, the supplement now comes with an improved formula too. Initially, TestoGen only contained 6 ingredients. The new revamped formula, however, not only adds 5 additional natural ingredients, but also tweaked some of the other ingredients a bit as well.

So, overall, TestoGen numbers 11 ingredients. I’ll go over each one of them so that you can see how they work together to help your body regain its youth.

1. Vitamin D

Vitamin D has quite a powerful impact on testosterone levels in men. For one, according to this study, men with higher Vitamin D levels had significantly more testosterone than men with lower VItamin D levels in their blood serum. Other things worth noting:

  • Vitamin D has a positive effect on sperm quality and motility (the ability to move actively and spontaneously while also consuming energy) - for both human and rat males.
  • Older men who take Vitamin D supplements tend to have higher chances of not having to deal with low T levels.
  • Also, according to this study, older men who have low Vitamin D levels tend to be associated with low free testosterone levels (as well as increased risk of experiencing fractures).

TestoGen relies on Vitamin D3 (also known as Cholecalciferol) to lift your free testosterone levels and also slows down the rate at which testosterone is converted into estrogen in your body.

Plus, Vitamin D seems to work really well when it’s taken alongside:

  • Vitamin K
  • Magnesium
  • Boron

And, as luck would have it, TestoGen already has those ingredients in the mix.

2. Vitamin K1 (New Addition)

Vitamin K1 mostly has positive effects on your bones, keeping them strong and healthy, and also helps with coagulation.

However, like I’ve just mentioned, it also does wonders when put alongside Vitamin D. Basically, it helps your body absorb Vitamin D much easier.

As a result, you get to enjoy enhanced testosterone-boosting capabilities from TestoGen (especially compared to the previous formula).

3. Vitamin B6

Vitamin B6 is quite essential when it comes to your body’s health, but it’s also linked with healthy testosterone production. Here is a study to show you what I mean. Basically, according to it, Vitamin B6 deficiency is correlated with low levels of circulating testosterone.

And yeah, I know that the study was done on Wistar rats, not human males. However, do keep in mind that their reproductive organs are mostly similar to ours, so the findings are valid.

Also, you should know that Vitamin B6 promotes the production of androgens, which are directly linked with higher testosterone production in the body. That, and Vitamin B6 is known to keep prolactin levels down.

What is prolactin? It’s a hormone responsible for low T levels in human male bodies, and also the culprit behind the “man boobs” syndrome.

Besides that, TestoGen’s B6-rich formula will help you keep fatigue at bay, and keep you in high spirits and motivated too.

4. Zinc

Not many people realize this, but Zinc has quite a huge influence on our bodies’ production of testosterone. Even the smallest daily Zinc intake can help increase T levels - in both professional athletes and average Joes.

Oh, and Zinc tends to act as an estrogen-blocker too, so bonus points for that.

And since oysters are one of the richest foods in Zinc, it’s clear that it’s just easier to take TestoGen then to stuff your mouth with oysters on a daily basis (unless you can afford to, and you enjoy it).

That’s not all, though. Zinc is also seen as an aphrodisiac, meaning it can help boost your libido. And I’m not just saying that - this study showcases how Zinc can enhance the sexual competence of male rats (once again, since our reproductive systems are similar, the results are relevant for human males too).

If you’re an athlete or just like going to the gym on a regular basis, TestoGen will really come in handy since our bodies tend to lose Zinc whenever we sweat - especially since our bodies can’t synthesize Zinc on their own.

5. Bioperine (New Addition)

Bioperine works very well with testosterone supplements in general, making it easier for your body to absorb the ingredients, which - in turn - makes the supplement way more efficient.

So, thanks to this new ingredient added into the mix, TestoGen is now more effective than it was before - so all the more reason to use this supplement if your T levels need a boost!

6. Fenugreek Extract

Fenugreek extract doesn’t just have positive effects on your body’s testosterone - it can also do wonders for your libido. It can also promote muscle development because the extract increases insulin release in the body.

And since Fenugreek is safe and has antioxidant properties, it can also benefit your health.

What’s more, Fenugreek is extremely efficient when combined with Zinc and Magnesium (both ingredients found in TestoGen). As a result, you can expect the testosterone-enhancing properties of this supplement to be even better.

7. Red Ginseng Extract

Red Ginseng is a plant that’s a very well-known aphrodisiac. Not only that, but its libido-enhancing abilities can actually help keep your testicles healthy by keeping dioxin damage at bay and promoting strong erections.

And those aren’t just claims, by the way. There have been plenty of studies done that showcase how efficient this plant is:

  • This study found that Red Ginseng can actually be used to treat erectile dysfunctions.
  • Here’s another study showcasing the same thing - that men taking Red Ginseng were more satisfied with their erections.
  • And, here’s a study that can showcase the testosterone-boosting abilities of Red Ginseng. According to it, this plant can decrease blood glucose levels in humans. Well, don’t forget that high blood glucose levels are usually associated with low T levels.

So, there’s no doubt that this ingredient makes TestoGen an excellent choice for any man who wants to take his sex life to the next level, or just wants to make sure his libido stays healthy.

8. Nettle Leaf Extract (New Addition)

The main idea is that this extract likes to bind itself to the SHBG (Sex-Hormone Binding Globulin) protein (the very same one testosterone tends to bind itself too).

Thus, the testosterone that would normally be binded to the protein in question will now be free to roam in your body’s bloodstream, which is much better for your body’s health as a male.

Essentially, your body will enjoy higher free testosterone levels, which can be put to good use by the rest of the ingredients found in TestoGen.

9. D-Aspartic Acid

D-Aspartic Acid’s main job is to help produce hormones - especially the luteinizing hormone, which is responsible for triggering the Leydig cell production of testosterone in males.

To prove how efficient D-Aspartic Acid is for T levels, here’s a study showcasing how men who took D-Aspartic Acid over a period of 12 days experienced an average increase of 42% in testosterone levels.

Besides that, D-Aspartic Acid has also been shown to improve sperm quality and even help men who experience infertility issues - to a certain degree, of course.

10. Boron (New Addition)

You wouldn’t think that a mineral that’s apparently a left-over since the Big Bang would also be a T-booster, but here we are. Yes, as it seems, even a small amount of Boron can do wonders for your body’s testosterone production.

I mean, just check out this study. According to it, after a week of taking a small daily dose of Boron, the study participants experienced the following:

  • A 39% decrease in free estrogen levels
  • A 28% increase in free testosterone levels
  • A significant drop in inflammation biomarkers

Gotta say - I’m definitely impressed by this, and am more than happy they decided to add this ingredient to TestoGen.

11. Magnesium (New Addition)

Magnesium isn’t just a vital nutrient for your body - it’s also quite good when it comes to enhancing testosterone production. It’s so good that it can actually increase free testosterone levels in your body by 24% - especially if you are engaging in intensive exercises.

Plus, according to this study, it seems that older men who had higher serum Magnesium levels also had higher T levels.

So, if you’re not getting your daily dose of Magnesium (and it seems that most people are not getting it nowadays), TestoGen has got you covered since they added a decent dose of Magnesium to their supplement.

TestoGen - How to Take It

The thing I like about TestoGen is how easy it is to take it. All you need to do is take up to 4 capsules a day right after you eat something - pretty simple, right?

So, you don’t need to worry about not being able to space out Testogen over the course of a whole day.

As how long you need to take TestoGen for - well, as long as you want. However, I do recommend taking a short break (2-3 weeks) from the supplement every few months or so - you know, just to make sure your body is functioning well on its own too.

And no, you don’t need to make any specific changes to your diet (though improving it with some testosterone-enhancing food certainly won’t hurt).

TestoGen Results - What Can You Expect?

Essentially, it all depends on what you are taking TestoGen for. If you want to enhance your mental focus and fortitude, you’ll probably see some changes within a week/a week and a half.

However, if you are taking TestoGen for muscle and strength development, you will have to settle for a month to six weeks - depending on your workouts, and physical and mental health, naturally.

In my case, I saw changes take place at the 2 week mark on the mental part. I was suddenly able to concentrate better and for longer periods, and no longer felt as tired in the morning as I usually did before taking TestoGen.

The physical changes took place at the 3 week mark, but there were some signs of changes taking place at the 2 week mark as well (faster recovery time after a gym session).

Around the 3 week mark, though, I’ve started feeling stronger than before, and was also able to lift more than before.

Here's a collection of before/after pics I've collected from different online sources. These are results with Testogen by customers who pictured their "before" physique and then after 3-4 months of taking it.

TestoGen Side Effects

The part many of you were probably quite interested in reading. I know how you feel - when it comes to testosterone boosters, I always check the side effects first.

Well, you’ll be happy to know you don’t have much to worry about with TestoGen.

Personally, I haven’t really experienced any side effects, but I’ve heard some customers complain about increased acne issues since they started taking TestoGen.

Now, before you start worrying, you should know that acne outbreaks are usually a sign of increased testosterone.

I mean, just think about it - when testosterone is increased, the big number of androgens in your body will cause the sebaceous glands (the base of the hair follicle) to produce more sebum. When that happens, there’s plenty of chances a pimple will develop.

If that happens to you, my advice is to double-down on your bodily hygiene (since it’s paramount to preventing pimples when dealing with excess sebum).

You can also try using some skin clearing products, or see a dermatologist too.

Also, according to a study, testosterone boosters can usually cause other side effects such as:

  • Gynecomastia
  • Decreased sperm count (in older men)
  • Prostate enlargement (in older men)
  • Testicular atrophy
  • Liver issues
  • Hormone suppression

I’m not mentioning this to put you off from TestoGen, but because I feel like I should be open about this. However, it is paramount to understand that most of these issues tend to occur if you take multiple testosterone or hormone supplements at the same time.

That, and the study itself refers to testosterone supplements in general, and doesn’t refer to TestoGen by name.

So, to be on the safe side (especially if you’re older), you should just stick to TestoGen and nothing else. You can also just do a “test-drive” for a few weeks or up to a month to see how your body reacts to TestoGen as well.

TestoGen - Where to Buy

Now this is something some customers have a problem with - you can only buy TestoGen from their official website. So, you shouldn’t get your hopes up about being able to find a better deal by accessing a TestoGen Amazon link or anything like that.

Personally, I don’t have such a huge issue with this - the supplements are a bit pricey but the number of capsules per bottle is pretty decent. On top of that, you can also take advantage of a “buy 2 get 1 free” or “buy 3 get 2 free” offer.

Plus, think of it this way - at least this way you don’t have to worry about any scammers out there trying to take your hard-earned money since you know there’s only one way to purchase TestoGen.

TestoGen - Pros and Cons


  • Can offer a decent libido boost, and can also help you enjoy stronger erections.
  • It keeps your mind more alert, and enhances your ability to focus.
  • Reduces recovery time after gym sessions, and helps you lift more.
  • Some of the ingredients help enhance the quality of your sperm.
  • Most customers are extremely pleased with the product.
  • TestoGen comes with a 60-day money-back guarantee, which means your investment is quite safe (plus you have enough time to see if you experience any results).

  • Can get a bit pricey (a minimum of around $55-60/month).
  • Some users might experience acne issues, or other side effects if taking other supplements alongside TestoGen.
  • Might take a while to see results, so patience is key.
  • Can only be bought through the official website (so no budget deals). On the flip side, at least you know that you won’t need to worry about any scams or so.


Prime Male vs. TestoGen

prime male

Well, the main difference is that Prime Male is more suitable for men who are over 30 years old, while TestoGen is suitable for any man who is over 18 years old. So, TestoGen is much more flexible in that regard. 

Regarding results, both supplements aim to offer you the same thing - restored vitality, enhanced strength and libido, and increased T levels.

And when it comes to the formula, Prime Male has 12 ingredients compared to TestoGen’s 11 ingredients. So not a huge difference. Here’s a quick overview of both supplements’ formulas:


  • Fenugreek extract
  • Red Ginseng extract
  • Magnesium
  • Vitamin K1
  • Zinc
  • VItamin B6
  • Bioperine
  • Nettle Leaf extract  
  • D-Aspartic Acid 
  • Boron 
  • Vitamin D 

Prime Male:

  • Zinc
  • Vitamin K2 
  • Vitamin B6 
  • Vitamin D3 
  • Nettle Root extract 
  • Mucuna Prurien extract 
  • Magnesium  
  • Luteolin 
  • Red Ginseng extract 
  • Bioperine 
  • Boron 
  • D-Aspartic Acid 

While Prime Male is missing TestoGen’s Fenugreek extract, it does make up for that with its T-boosting Vitamin K2 ingredient, and its dose of aromatase-blocking Luteolin.

In terms of side effects, customer reviews seem to point to Prime Male causing nastier effects, such as:

  • Mood swings
  • Headaches
  • Diarrhea
  • Upset stomach
  • Acid reflux
  • Changes in blood pressure

Naturally, this can vary from person to person, and you’ll probably be less likely to experience any of those symptoms if you take Prime Male alone - without adding any other supplements to th diet.

As for price, Prime Male is a bit steeper if you’re just buying month-to-month since it’s around $60/box.

The bundle deal is similar in price to TestoGen (around $179-180), but the deal itself is inferior since you only get 4 boxes (3+1 free) from Prime Male, while TestoGen’s deal gets you 5 boxes (3+2 free).

Oh, and Prime Male offers a 90-day guarantee as opposed to TestoGen’s 60-day guarantee. Though, to be honest, that’s not really gonna make a huge difference since you’re supposed to see results under 60 days.

Personally, I’d say choosing between these supplements is up to your own preference (and age, of course). If you’re over 30 and are also engaged in serious physical activity, I’d recommend going with TestoGen (because of its formula and ingredient amounts). Otherwise, Prime Male can be a decent alternative too.

TestoGen vs. TestoFuel


TestoFuel and TestoGen aim to do pretty much the same thing, with the exception that TestoFuel also claims to improve your metabolism and your body’s HGH production. Both supplements are ideal for males who over 18 years old and engage in physical activity, or older males who want to regain their vitality.

Ingredients-wise, TestoFuel only has 8 compared to TestoGen’s 11 ingredients. Here’s a quick overview:


  • Fenugreek extract
  • Red Ginseng extract
  • Magnesium
  • Vitamin K1
  • Zinc
  • VItamin B6
  • Bioperine
  • Nettle Leaf extract  
  • D-Aspartic Acid 
  • Boron 
  • Vitamin D 


  • Zinc
  • Vitamin K2 
  • Vitamin B6 
  • Magnesium 
  • Fenugreek 
  • Ginseng 
  • Oyster extract 
  • Vitamin D 
  • D-Aspartic Acid 

TestoGen seems to have the upper hand in this case. And it’s not just because it contains more ingredients, but because the extra ingredients it has are quite vital for properly enhanced testosterone production (especially because it contains Boron).

When it comes to side effects, I haven’t really found much on TestoFuel other than some users complaining about an upset stomach and headaches, which sounds a bit better than TestoGen’s acne issues.

All in all, the side effects can vary according to your body and if you take additional supplements or hormones.

In terms of price, one box of TestoFuel is pretty much similar to one box of TestoGen (around $55).

TestoFuel’s bundle deal is a bit more budget-friendly (around $166 compared to TestoGen’s $179-180) but you’re only getting 4 boxes (3+1 free) instead of 5 (3+2 free).

TestoFuel comes with a 90-day guarantee as opposed to TestoGen’s 60-day guarantee, but you don’t really need that much time to see results.

As for what I recommend, it depends if you feel safer taking a supplement with some more history backing it. If that’s the case, you’ll probably prefer TestoFuel over TestoGen. But if the quality of the ingredients really matters to you, and you want to enjoy great deals too, TestoGen will be a better pick.

Testogen XR vs. TestoGen

testogen xr bottle

It’s easy to get the 2 confused - given their names. However, Testogen XR is part of the Ronnie Coleman Signature Series, so that might make it a bit more popular with the testosterone supplements crowd. 

Both supplements pretty much aim to do the same thing, with the exception being that Testogen XR focuses on increasing nitric oxide levels in the body too.

That, and Testogen XR usually comes in powder form, though you can also find it as pills too. Oh, and it’s available on Amazon and other retail websites - not just on one official website.

That means you might be able to take advantage of better deals.

In terms of ingredients, TestoGen has the upper hand both when it comes to numbers and quality.


  • Fenugreek extract
  • Red Ginseng extract
  • Magnesium
  • Vitamin K1
  • Zinc
  • VItamin B6
  • Bioperine
  • Nettle Leaf extract  
  • D-Aspartic Acid 
  • Boron 
  • Vitamin D 

Testogen XR:

  • L-Carnitine Tartrate
  • Horny Goat Weed 
  • D-Aspartic Acid 
  • Nettles Root 
  • Astragin 
  • Agmatine 

When it comes to Testogen XR side effects, the most common complaints seem to be about headaches and diarrhea, whereas some TestoGen users just complained about acne outbursts. In the end, the experience isn’t the same for everyone, and it all depends on your body.

I also highly recommend not taking any other supplements besides the main one.

As for the Testogen XR price, it depends on the retail website you buy from.

Usually, it seems to mostly be available on Amazon, where I’ve seen prices for 1 box/bottle range between $10 and $40.

TestoGen is obviously more expensive, but it’s easier to purchase it, and the official website offers decent deals.

I’d personally recommend sticking with TestoGen in this case because of its superior formula and better accessibility.

TestoGen Reviews - Overwhelmingly Positive

how testogen works

NOTE on Post-Cycle Therapy

Although not a prerequisite it is recommended that you take a break from Testogen every few weeks so that your body doesn't go into hibernation mode since the supplement will be doing all the hard work increasing your test for you.

Although natural and with no science to date to claim otherwise, there are no side effects associated with Testogen.

However, since everyone's body reacts differently, do keep in mind that perhaps it's best to test drive it for a few days to weeks before concluding on its safety and ultimate efficiency

TestoGen FAQs

What about Shipping?

As far as I know, TestoGen is shipped worldwide by the supplier. Still, it’s a good idea to contact them by phone to let them know what country you are from. This way, they’ll be able to provide you with a more accurate delivery estimate.

Also, you should always do your research to see if the country you live in considers the substances found in TestoGen to be “problematic.” They are completely safe, but you know how governments can be, so it’s better to be safe than sorry to make sure you won’t have any nasty surprises when the package reaches your country.

Can TestoGen Be Used in Sports or Competitions?

Basically, it depends on the rules the regulative authorities in your country impose for the type of competitive sport you practice. You need to research them before ordering TestoGen to make sure the ingredients in the supplement (or the supplement itself) are allowed.

Does TestoGen Cause Prostate to Be Enlarged?

Like I already mentioned, something like this might happen if you take other supplements alongside TestoGen.

Yes, chemical testosterone has a tendency to cause users to experience prostate enlargement. However, please keep in mind that TestoGen is pretty much natural (as you’ve seen, it’s just made from completely natural ingredients). So, it doesn’t really fall into the chemical testosterone category.

Does Taking TestoGen Increase Risk of Cancer?

A heavy question, but one that should never be omitted. As far as I can tell from my research, the supplement hasn’t be found to have such an effect on a user’s prostate. However, since it does contain Zinc, there might be a risk of developing prostate cancer according to this study - if you take too much, that is.

Apparently, over 100 mg/day of Zinc can increase your risk of developing prostate cancer. How much Zinc do TestoGen capsules have in them? Well, I got in touch with their customer support, and - according to them - a daily dose has around 72 mg.

Besides that, here’s what else you should know:

  • Boron (one of the ingredients in this supplement) has been found to help protect against prostate cancer, so there’s that too.
  • According to this study, Fenugreek (another ingredient found in TestoGen) actually has potential to act as an anticancer agent since it is cytotoxic (kills living cells) but only for cancer cells, not normal ones.
  • Magnesium (yet another ingredient) seems to have an influence on prostate cancer. Apparently, if one has low blood Magnesium levels (especially as they age), they have a higher risk of developing prostate cancer.
  • Ginseng (you guessed it - another ingredient) has been found to seriously reduce the risk of cancer development. What’s more, Ginseng extract (exactly what you can find in TestoGen) is considered to be among the most efficient methods of preventing the onset of cancer.

So, as long as you take TestoGen the way it’s intended to be consumed, you shouldn’t have to worry about this.

TestoGen & Blood Pressure - Is There a Link?

As far as I can tell, you don’t need to worry about TestoGen raising your blood pressure. In fact, since its main purpose is to increase your T levels, that should reduce your blood pressure. After all, don’t forget that low testosterone levels in the body have been linked to high blood pressure.

Can You Get TestoGen Free Samples?

No, there is no way to get your hands on something like that. Still, you can get 1-2 free bottles of TestoGen if you buy their bulk deals.

To be honest, it kind of makes sense there are no free samples, since they’d need to offer you at least 2 weeks worth of TestoGen for free for you to start seeing results, which isn’t really profitable for them.

Bottom Line

If you’re looking for a decent T-booster to take your workout or sex life to the next level, or relive your youth (so to say) by increasing your libido, you can’t go wrong with TestoGen. Its ingredients are more than worth the money, the deals are great, and the results are more than real.
