Testogen contains some excellent ingredients. In fact, the ingredients cover pretty much everything we could ask for from a natural testosterone booster. The only problem is that the doses are all way too low! Testogen has clearly modeled itself on some of the most popular testosterone boosters on the market right now, but the manufacturers have cut back far too much on the serving sizes. Whether this was done to keep costs down, or just because they didn’t know what they were doing, we have no idea. We do know that the end result is a seriously weak testosterone booster. Testogen can reasonably be described as a weaker version of Prime Male; many of the ingredients are the same, but the doses are lower!
This stuff is priced the same as many of the leading testosterone boosters on the market right now (and considerably more than a few of them). We really don’t see how the makers of Testogen can justify that kind of price for such a weak supplement!
Our Testogen Review
Testogen doesn’t really need much of an introduction. It is without doubt one of the most recognizable and well-known testosterone boosters on the market. This has been the case for some time now. Testogen was first launched by Wolfson Berg Limited a good few years ago. Since then, it has remained one of the most popular natural bodybuilding supplements out there. It is recommended by several supplement review sites, and there are thousands of individual reviews out there from satisfied customers.
So what does Testogen do then?
Why do seemingly so many people use it?
The box itself tells us right away what this product is all about. It lists four key benefits that users can expect:
Of course, increased strength, stamina, and libido will all follow from having higher free serum testosterone levels. That is what we are really looking for here.
Some testosterone boosters treat the symptoms of low testosterone individually without actually addressing the root cause of the issue. Or to put it another way, they give you a cheap energy boost and some aphrodisiacs without doing a damn thing for your testosterone levels!
Such scams are of no interest to us. We know that natural testosterone boosters can work. We look for products which actually increase natural testosterone production, decrease estrogen conversion, and put deficiencies right.
Does Testogen really work?
How does it compare to the best testosterone boosters available right now?

The first thing you’ll no doubt be wondering is “what is in Testogen?”
The website isn’t very helpful with this one; they’ve made it really difficult to find out what’s actually in Testogen. Sure, they talk about the new ingredients a lot, and what they can do, but the main pages don’t show a full ingredient panel.
As far as we can tell, there’s one shot of the full formula on the website – a tiny, blurry image found in the FAQs.
Here’s the best image of the Testogen formula we were able to pull from the website:
That is NOT the formula we were hoping to see.
Right away we’re struck by how small the servings are – just 40mg for both Nettle Leaf Extract and Ginseng?!
The ingredients themselves aren’t a problem. They all have a place in a natural testosterone booster. Fenugreek is not a potent testosterone booster in and of itself, but it does improve libido, so we do think it can add to a good supplement.
The only real issue is the doses. For a supplement which claims to be the most effective, potent product on the market, we really expected to see more generous servings!
Testogen shares ingredients with lots of other testosterone boosters, but other products have it beaten hands down on power. In many ways, Testogen is just a weaker, less comprehensive version of Prime Male!
For the price we’re expected to pay for Testogen, we would like to see TWICE this much Vitamin D, more D-Aspartic Acid (or a higher quality form of D-AA), more Ginseng, more Nettle Root, and about triple the amount of zinc. We don’t know how Testogen can possibly justify their price tag – which is more than some of the best testosterone boosters around today – with such poor serving sizes.
There’s also some big gaps in that formula.
There’s no Mucuna Pruriens, so no extra LH/FSH stimulation.
There’s no natural aromatase inhibitor.
For some reason, these guys have also gone with Vitamin K1 instead of K2; a big mistake we’ll come back to later.
Overall, this is a pretty poor supplement. We have no idea why Testogen has remained so popular over the years with such a low-grade, under-powered, thin formula.
However, things aren’t all bad. There are some very good aspects to this supplement which we should go through. Once we’ve done that, we’ll take you through the main drawbacks in more detail.
Main Strength – Good Collection Of Ingredients
One thing that cannot be denied is the fact that Testogen contains some excellent ingredients.
The formula actually provides many of the best natural testosterone boosters in existence. It definitely provides most of the true staples that we expect to see in every modern test booster.
For example, Testogen contains a fairly reasonable dose of D-Aspartic Acid (D-AA).
We’d go as far as to say that D-AA is a necessary ingredient for a testosterone booster now. We know that it works, and that it works very well for the vast majority of people. It is safe, it directly promotes your own natural testosterone production, and it isn’t very expensive in its basic form (which we have here). All in all, there’s no excuse for leaving this stuff out of your stack.
D-AA supplementation stimulates the production of Luteinizing Hormone in the pituitary gland. LH then acts as a ‘trigger’ for the production of testosterone in your testes. The Leydig cells in your testes recognize LH and they immediately begin releasing more test. Some studies have found that D-AA supplementation can significantly raise free serum testosterone levels in men in as little as 12 days (ref).
Testogen provides 2352mg of D-Aspartic Acid. This isn’t the largest dose we’ve seen, but it is enough to give the vast majority of users some good benefits.
Testogen also utilizes Stinging Nettle Extract.
In our opinion, this is a really under-appreciated ingredient. Stinging Nettle Root is an excellent natural testosterone booster; safe, reliable, and its mechanism of action is a little different to most of the ingredients you’ll find in your average test booster.
Stinging Nettle Root contains compounds called lignans. These compounds bind to Sex Hormone Binding Globulin. This reduces the amount of SHBG that is ‘active’ in the blood. Normally, SHBG binds to testosterone. This mean testosterone can’t act on your androgen receptors. In other words, SHBG renders free serum testosterone useless. By binding to SHBG, the lignans in Stinging Nettle Root ‘take the bullet’ for testosterone. The end result is higher free and total testosterone (ref).
There is one VERY IMPORTANT thing to note here, however.
Lignans are found in large quantities in Stinging Nettle Root.
Everything we have said above has been about Nettle Root.
Testogen contains Nettle Leaf Extract.
Nettle leaves do not contain anywhere near as much lignans as the root does. All of the studies looking at Nettle supplementation and testosterone have used Nettle Root Extract, not Nettle Leaf Extract. There is no reason to think that the two would work equally well for elevating testosterone.
The use of Nettle Extract is definitely a positive, but this could easily be viewed as a weakness in Testogen because of the fact that it is a leaf extract and not a root extract.
Main Weakness – Low Doses
Without doubt the biggest flaw here is the poor servings.
Pretty much every ingredient in Testogen – every important ingredient at least – is dosed lower than we would expect from a top quality testosterone booster today.
For example, the D-Aspartic Acid mentioned above is dosed at a very strange 2,352mg per daily serving.
Most studies looking at D-AA and its ability to boost testosterone have used 3.2g per day. So that’s what many good quality testosterone booster provide. High-end testosterone boosters today sometimes use a more refined, potent form of D-Aspartic Acid called D-Aspartic Acid Calcium Chelate. This form of D-AA is highly bio-available. In fact, you only need about 1,500mg of D-AACC to get the same results as 3.2g of regular D-AA.
Testogen uses regular D-AA. As such, we’d ideally like to see a lot more per daily serving.
A bigger offender is the Vitamin D. Each serving of Testogen provides just 50mcg of Vitamin D3.
We expect to see 5000IU of Vitamin D3 – or 150mcg – per serving from a premium testosterone boosting supplement. Today, 5000IU is pretty much the standard, benchmark dose for D3; the vast majority of top quality testosterone boosters provide this much.
Vitamin D is, after all, safe to take in large doses. It is extremely effective, and most people in northern Europe and North America are deficient. The more the merrier. So why dose it so low?
Then there’s the Nettle Leaf Extract. We’ve already mentioned above that Nettle Leaf Extract may not have the same effects as Nettle Root Extract. But even if it did, 40mg would not cut it. Not even close.
Top quality testosterone boosters will usually go heavy on the Nettle Root Extract. Prime Male, for example, contains 160mg of potent Nettle Root Extract. That’s 4 times times the Nettle Extract we get from Testogen. On top of that, it’s the lignans-rich Root with Prime Male rather than the ineffective leaf we get from Testogen.
We could go on and on here. Compared to other products – good products at least – Testogen is under-powered. Even the zinc and magnesium doses are low!
If you’re going to include ingredients like Nettle Extract, Ginseng, and Fenugreek, you may as well dose them properly.
That Testogen under-doses these ingredients so severely is a major problem. It is unlikely that users will see the full potential of what these substances can do using such small quantities. In our opinion, they may as well not be in the formula at all.
Massive Flaw – No Aromatase Inhibitor
Another huge flaw with the Testogen formula is that it lacks some key ingredients.
There are substances which we know to significantly raise serum testosterone levels in healthy men. They are well-proven, widely-used, and safe. They are commonly found in premium testosterone boosters today.
Yet Testogen lacks these staple, core ingredients which we look for in every good testosterone booster.
For instance, Testogen is missing a natural aromatase inhibitor.
All of our top rated testosterone boosters contain a natural aromatase inhibitor. The most commonly used aromatase inhibitor in natural testosterone boosters is luteolin.
Multiple clinical trials have found that luteolin is effective at inhibiting aromatase expression. One trial even found that luteolin administration “promoted aromatase protein degradation and inhibited estrogen biosynthesis in aromatase-expressing HEK293A cells”. The researchers from the cited study were confident enough in luteolin’s abilities to conclude the following:
“Estrogen biosynthesis in KGN cells was inhibited with differing potencies by extracts of onion and bird chili and by four other dietary flavonoids: kaempferol, quercetin, myricetin, and isorhamnetin. The present study suggests that luteolin inhibits estrogen biosynthesis by decreasing aromatase expression and destabilizing aromatase protein, and it warrants further investigation as a potential treatment for estrogen-dependent cancers.” (Published 2012 in Journal of Agricultural and Food Chemistry).
That Testogen is missing such an excellent ingredient is a pretty big flaw. The fact that it is missing any kind of aromatase inhibitor is a major issue.
All good testosterone boosters will come at the problem of low testosterone from multiple angles, and reducing estrogen conversion is a really important one.
Increasing your own natural testosterone production is great, but if aromatase is converting much of it to estrogen then your efforts will be fruitless. There is a reason that most bodybuilders use an aromatase inhibitor; excess testosterone might lead to excess estrogen.
The same is true when using natural testosterone boosters – you need a natural aromatase inhibitor!
Minor Flaw – Vitamin K1 Not K2
A small but not insignificant problem with Testogen is the fact that it uses Vitamin K1 instead of the much more useful K2. We don’t think there’s any point including K1 in a supplement; if you’re building a stack designed to maximize healthy and performance in any way, it’s always a good idea to use K2 instead of K1.
Vitamins K1 and K2 are not just slightly different forms of the same substance. They are actually quite different, and they do not have the same dietary sources at all.
K1 – also known asphylloquinone – is highly prevalent in the human diet. It is found in very large quantities in leafy green vegetables like spinach, chard, kale, and parsley. If you’re eating a healthy, well-rounded diet, then you’ll be getting plenty of Vitamin K1.
Vitmain K2, by contrast, is very difficult to come by in the normal human diet. The most abundant source is Natto; a dish of fermented soy beans very popular in Japan. Small amounts are also found in goose liver (as well as other organ meats), butter, egg yolks, and other fatty animal-derived foods.
Now, Vitamin K1 can be turned into K2 in the body (source). We therefore don’t need to worry too much about Vitamin K2 intake. The body will turn K1 into K2 as and when it is needed.
However, while deficiency is unlikely, we’re talking about maximizing testosterone synthesis. Our goal is to optimize, not just get by.
Since K1 is so abundant in the human diet, why have the makers of Testogen bothered including it here?
Wouldn’t it have made much more sense to just include some K2, since we hardly get any from our diets?
That is what supplements are supposed to be for after all!
We think this is another example of sloppy ingredient choices and cost-cutting which we see all over the Testogen formula. The use of Vitamin K1 instead or K2 is quite similar to the use of Nettle Leaf Extract instead of Nettle Root Extract – it’s either cheap, lazy, ignorant, or all three.
So What Does Testogen Do?
We’ve gone through the flaws and the strengths of this testosterone booster. We’ve explained what we like, and what we’d change. We have (hopefully) explained what each ingredient does, how it does it, and what that means for you.
But many of you will still be wondering what Testogen does!
What does all of this mean for you?
What does Testogen do in terms of actual, practical results?
In our opinion, not a lot.
Overall we think the weaknesses outweigh the strengths here. The ingredients are good, but the doses are just far too low across the board.
In more than one case, the manufacturer has been very sloppy with the ingredient selection. Nettle Root is a potent testosterone booster; Nettle Leaf is not! D-Aspartic Acid Calcium Chelate is an industry benchmark. Regular D-AA is not.
In short, we think the average Testogen user will experience the following:
- A moderate improvement in recovery time
- Slightly faster muscle growth
- Increased sex drive
Results are always going to be meager with such an under-powered supplement.
Testogen Side Effects – Is It Safe?
One big selling point of Testogen is the fact that it looks highly unlikely to cause any serious side effects.
Testogen only contains natural ingredients which you could conceivably find in the human diet – just not the average human diet!
Each ingredient has been extensively studied and has been found to be generally safe for human consumption. Most of the studies looking at these substances have been limited to about 28 days in length. However, we’re not aware of any paper which highlighted potential long-term dangers. The consensus is that these substances can be supplemented safely at these doses on a regular, long-term basis.
Of course, everybody is different. We’re just talking about the average user here. There are obviously some circumstances in which Testogen will cause side effects. Perhaps you have a pre-existing medical condition which makes it unsuitable, or maybe you are currently following an unusual diet/supplement regiment which makes interactions a possibility.
That is why it is so important for each one of you to do your own research and consult with your regular family doctor before using Testogen, or any natural testosterone boosters for that matter.
On the whole though, we think 99.9% of you will be able to take Testogen without any issues whatsoever.
Our main issue with this supplement is the low doses, and low doses usually mean no side effects!
It’s extremely important for you to remember the following facts while reading our supplement reviews:
- We are NOT doctors
- This is NOT medical advice
- You must do your own research and talk to a doctor before using any of these supplements
If you think you are struggling with chronically low testosterone, you need to talk to a doctor asap. They might find that you are not producing anywhere near enough testosterone, in which case they might prescribe TRT.
Testogen User Reviews – What Are People Saying?
It’s always worth taking a look at what other people have been saying about a supplement before you buy.
User reviews aren’t always accurate – that’s putting it mildly.
But they do give you a taste of what a product has to offer.
Here is a selection of Testogen user reviews taken from the web:
Unfortunately, there aren’t many more Testogen user reviews out there for us to include here. The website claims that there are “thousands of satisfied customers”, but they don’t show their testimonials.
There aren’t many on Amazon either.
A lack of user testimonials or celebrity endorsements is always a bit of an alarm bell to us. It doesn’t mean it is necessarily a bad supplement. It’s just that lots of user reviews and celebrity endorsements is a good sign that something isn’t a total rip!
Testogen Review Summary – Is It Any Good?
So, what are our findings? Does Testogen work? Is it any good?
Testogen does look like it will work, but it doesn’t look like it works anywhere near as well as some of the other testosterone boosters out there right now.
In our opinion, Testogen just doesn’t cut it in today’s market.
The standard for natural testosterone boosters has been raised significantly over the last few years. Testogen dominated the market for a good few years, but it has definitely been overtaken by some f the newer arrivals.
Testogen contains some great ingredients, but the doses are way too low to make a big difference to your testosterone levels.
The ingredient quality is also poor in places; Nettle Root is a good SHBG binder, Nettle Leaf is not at all. This is either Testogen’s makers being cheap, or they just don’t pay attention to the details!
We see Testogen as basically a weaker, cheaper mash-up of Prime Male and Testofuel. It lacks the power of either, and the value for money is way lower than these two top-notch stacks.
All things considered, you can do a lot better than Testogen!
Does Testogen have an estrogen blocker or aromatase inhibitor?
No. Testogen does not have an “estrogen blocker”. People usually mistakenly refer to aromatase inhibitors as “estrogen blockers”; in practice, the end result is the same even if the terminology is inaccurate. The lack of an aromatase inhibitor is a major flaw with this supplement. Most top quality testosterone boosters today provide at least one aromatase inhibitor. Nettle Root may have some aromatase inhibiting properties, but there’s no reason to think that Nettle Leaves have the same effects.
Is Testogen FDA approved?
Testogen is a natural supplement, which means it falls outside of the FDA’s remit. It therefore lacks FDA approval, as do all nutritional supplements not sold as medicines.
How Long Does Testogen Take To Work?
The main ingredients in Testogen don’t work immediately. Manipulating hormone levels takes time, and it takes even longer for you to see a physiological difference (in muscle size, strength, energy, confidence, etc). In general, we think Testogen will start to properly work after about 3-4 weeks of regular, consistent use. You will probably notice the biggest differences during weeks 5 and 6. This is just how natural testosterone boosters work!
How To Take Testogen
Each daily serving of Testogen is split up into 4 capsules. In order to get the most out of any natural testosterone booster, it’s best to take it at regular intervals throughout the day. By doing so, you can keep giving your body a prompt to produce more testosterone all day. This will help keep your testosterone levels high round the clock.
That said, if you want to take 2 capsules with breakfast and 2 with dinner, there’s absolutely nothing wrong with that. The formula is designed to work over the long-term. Taking 4 capsules per day with food is just the optimal way to take it; it isn’t necessary.
Where To Buy Testogen
Testogen is sold exclusively through the main merchant site. We have seen some bottles appear on Amazon in the past, but we believe that these are unlicensed re-sellers; not to be trusted!
