Testogen Review: Our Certified Nutrition Coach’s Personal Results

by Joe Costello, CNC | Testosterone Boosters

Testogen testosterone booster supplementTestoGen is an all-natural testosterone booster that recently burst on the scene in an increasingly crowded marketplace for these oh-so-popular male performance supplements. We are impressed with this test-booster and with a thoughtful blend of all-natural ingredients in the right potencies, this TestoGen review will show you this testosterone booster is the next big thing.

For those new to test-boosters, let’s talk quickly about testosterone and the need for testosterone boosters.

As a man ages, his testosterone will slowly decline. By the time men reach the approximate age of 35, the symptoms of declining testosterone are usually beginning to surface.

Lower than optimal levels can result in insomnia, weight gain, low energy levels, depression, reduced muscle mass, and low sex drive. Can Testogen solve the problem? In my personal experience using Testogen, I got amazing results. That doesn’t mean it will work for everyone, but for me, this stuff was AWESOME. My personal results were just amazing…suffice it to say, I was killing it in the gym and the bedroom. As a Certified Nutrition Coach, I frequently recommend Testogen to my clients and strongly recommend it to my readers online as well.

Testogen is at the very top of our list of the top ranked testosterone supplements.

My Personal Testogen review: Is Testogen any good?

Testogen, made by Muscle Club, is undoubtedly one of the most effective testosterone boosters on the market right now. With the overall potency level nearing 3,000 MG per serving and over 10 total active ingredients, this formula is far superior to 99% of other test booster formulas when it comes to the potential to reach absolute maximum healthy testosterone levels and luteinizing hormone levels.

I have personally used this Testogen for muscle growth many times. I’m not quite at the point in my life yet where my testosterone levels are getting low (otherwise known as Low T), but I do lift weights a lot and have found that Testogen gives me a major boost in terms of lean muscle growth and recovery. The last time I took it, it was for about 3 months, and my results were awesome both in terms of muscle growth and enhancing exercise performance. I gained 15 pounds of lean muscle mass very quickly. Plus, as I mentioned before, it helped me out in bedroom as well.

Testogen simply checks all of the boxes…high potency, quality ingredients, diverse formula, and excellent customer reviews. Plus, my personal experience with this product was great. I’m a big fan and will certainly be buying again! If you want to learn more about my analysis of the product, watch the video below. As a NASM Certified Nutrition Coach, I have to say this is one of the best formulas I’ve ever seen and the best personal experience I’ve ever had with a test booster. I actually got my testosterone levels tested after using it (as well as before), and my testosterone levels increased very significantly.

What does Testogen do?

What does Testogen do for you? This powerful supplement utilizes a combination of clinically researched natural ingredients to help ignite internal testosterone production. In other words, the formula is designed to get your body to naturally create more of its own testosterone. If this doesn’t sound like it’s possible to you, wait until you see what’s in it in the “Ingredients” section of the review. But first, here’s a bit about how natural dietary supplements like Testogen can actually boost testosterone levels.

Natural testosterone supplements are designed to support and optimize testosterone levels in the body through various mechanisms. It’s important to note that while these supplements may have some impact, they are not a substitute for medical treatment, especially in cases of diagnosed testosterone deficiency, otherwise known as “Low T” or Low Testosterone. Testosterone deficiency syndrome is not intended to be treated with natural dietary supplements.

You should always consult your doctor if you have been diagnosed with Low Testosterone or Erectile Dysfunction. Your doctor may say that you can go the natural dietary supplement route, but I’m not a doctor, so you certainly should check with them first. They generally recommend testosterone replacement therapy because testosterone therapy is simply the most clinically proven option. I personally don’t like testosterone therapy because it can involve injections and nasty side effects. In my opinion (again, I’m not a doctor), if you can stimulate testosterone production without testosterone therapy using a herbal and dietary supplements, I’m all for it.

I’ve seen a lot of horror stories with friends of mine who were diagnosed with low testosterone and tried testosterone therapy to achieve normal testosterone levels. A bunch of guys I know said the testosterone therapy itself is awful because it requires weekly doctor visits and injections. I also know several guys who tried testosterone therapy AND have also tried a natural testosterone boosting supplement, and they said it was the exact same in terms of their improved ability to stimulate natural testosterone production, boost muscle growth, and just really get noticeable results in general.

Again, I’m NOT saying natural supplements can cure low testosterone. I’m just saying I know guys who suffer form low testosterone, and many of them have said that herbal supplements worked very well for them. Here are some ways in which a natural supplement like Testogen may help out in terms of supporting healthy testosterone levels…

Nutrient Support

  • Some natural testosterone supplements contain vitamins and minerals that are essential for testosterone production. Key nutrients include zinc, vitamin D, magnesium, and vitamin B6.

Herbal Ingredients

Certain herbs found in a natural supplement like Testogen are believed to have testosterone boosting properties. Common herbal ingredients in natural testosterone supplements include:

    • Tribulus Terrestris: Stimulates testosterone production and increases luteinizing hormone levels according to certain clinical studies done by the NCBI.
    • Ashwagandha: Associated with improved fertility and testosterone levels.
    • Fenugreek Extract: Fenugreek extract may help increase testosterone levels, luteinizing hormone levels, and enhance exercise performance.

Zinc Supplementation

Zinc is a crucial mineral for testosterone synthesis. Natural testosterone supplements often include zinc to support healthy testosterone levels and stimulate testosterone production.

Vitamin D

Adequate levels of vitamin D are associated with healthy testosterone production. Some supplements such as Testogen include vitamin D to address potential deficiencies while also naturally increasing testosterone levels.


Magnesium plays a role in various physiological processes, including testosterone synthesis. Magnesium supplementation may support healthy testosterone levels, especially in individuals with deficiencies.

Lifestyle Support

Natural testosterone supplements often promote healthy lifestyle habits known to support testosterone production. This may include recommendations for regular exercise, exercise performance enhancement, stress management, and adequate sleep.

Adaptogenic Herbs

Adaptogens like ashwagandha and Korean red ginseng are believed to help the body adapt to stress, potentially supporting hormonal balance, including testosterone. Adaptogens are quite amazing in this way…they can help support healthy testosterone levels AND relieve stress, which is pretty awesome.

Testosterone Precursors

Some supplements include compounds that are precursors to testosterone, such as DHEA (dehydroepiandrosterone). The body can convert these precursors into testosterone. Testogen does not directly contain DHEA, but it does contain ingredients that have been shown to stimulate DHEA production within the body.

Anti-Estrogenic Effects

Some natural compounds such as stinging nettle leaf extract may have anti-estrogenic effects, helping to balance estrogen and testosterone levels. Examples include DIM (diindolylmethane) from cruciferous vegetables. Higher testosterone levels combined with lower estrogen levels is the key and ultimately leads to higher energy levels overall.

Testogen ingredients list

Here are the primary ingredients in Testogen:

D-Aspartic Acid

D-Aspartic Acid is a very powerful naturally occurring amino acid that has an enormous body of research supporting its potential with regard to promoting healthy testosterone levels. As a matter of fact, we do not recommend ANY test boosters that don’t contain this potent amino acid. We see D-Aspartic Acid as an absolute necessity and typically look for a dosage of about 2,000 MG. I have personally read many clinical studied on D-Aspartic Acid, its effect on exercise performance, and its potential to boost testosterone production. It’s a very promising T Booster ingredient.

Tribulus Terrestris

Tribulus Terrestris is progressively becoming more of a staple ingredient in natural testosterone boosters due to the growing body of research showing the tremendous benefits this natural herb can produce for the user. More specifically, many studies have shown Tribulus has big potential with regard to increasing libido in males as well as potentially contributing to increased testosterone production. I personally read a clinical study that suggested Tribulus Terrestris may in fact directly contribute to the achievement of healthy testosterone levels in some men. This hasn’t been proven, but the studies are very promising.

Korean Red Ginseng Extract

Ginseng is extracted from a root plant, and it has been touted as a natural aphrodisiac. It is said to have the ability to reignite the libido and lead to stronger erections. In addition, Korean Red Ginseng Extract has long been linked to helping naturally increase energy levels. Clinical trials conducted by the National Library of Medicine suggest it can also potentially contribute to increased testosterone production. You can really start to see at this point why I Testogen is in my opinion such a comprehensive supplement when it comes to boosting testosterone levels.

Fenugreek Extract

Fenugreek is a seed that not only has antioxidant properties, but it has also been shown to have the potential to boost libido and increase testosterone levels. Due to the amount of research backing this ingredient, we see it as one of the most critical inclusions and consider it an absolute staple ingredient in the test booster industry. Every one of our top recommended natural testosterone booster supplements has a healthy dosage of Fenugreek extract in it due to the vast array of research supporting the idea that it may contribute to increased testosterone production and therefore lead to healthy testosterone levels for the user.


Zinc is a mineral that many people aren’t aware that they’re deficient in. It is also a known aphrodisiac and is believed to help men’s bodies to produce more sperm. Additionally, researchers believe zinc may increase free testosterone levels and therefore libido. Look for Zinc dosage sizes of at least 25 MG. Zinc has been shown across several clinical trials to be linked to higher free testosterone levels, which makes it a very attractive addition to a potent formula like this one.

Stinging Nettle Leaf Extract

Stinging Nettle Leaf Extract was recently added to the Testogen formula due to the fact that it previously did not contain an estrogen blocker. Many researchers consider Stinging Nettle Leaf Extract to be an effective estrogen blocker, so this was a key addition to the Testogen formula…you definitely want to avoid estrogen levels getting too high. If you want to increase testosterone production and maintain healthy testosterone levels, you need a component of the dietary supplement you choose to contain sex hormone binding globulin SHBG in order to block estrogen levels, which is the purpose of Stinging Nettle Root. The bottom line is you want higher free testosterone levels and lower estrogen levels.


Testogen pros and cons

Here are the benefits and side effects of Testogen testosterone booster.

Testogen benefits

There’s a long list of potential Testogen health benefits we could cover, but let’s talk about this most important ones. When you use a testosterone supplement as potent as this one, you can experience health benefits including but not limited to…

  • Boost testosterone levels
  • Higher sex drive
  • Elevated energy levels
  • Improved athletic performance
  • Increased confidence
  • Enhance lean muscle growth

Imagine how you felt when your testosterone levels were at their peak in your early-mid twenties…that’s the best way I can describe how Testogen makes you feel if you use it properly. It’s typically most effective when used for a 2-3 month period, but you should start to notice results pretty quickly with regard to lean muscle growth. I personally noticed higher testosterone levels almost immediately, and as I said before, I actually went to get my testosterone levels tested to ensure I was correct, and they were in fact higher. I noticed a major change in my natural energy levels as well.

Testogen side effects

If you examine the SFP (supplement facts panel), you will not find a single synthetic ingredient. This is a 100% natural formula consisting strictly of herbs, vitamins, and amino acids. Therefore, side effects are highly unlikely unless you’re particularly sensitive to one or more of these ingredients.

With that being said, it is a very powerful supplement and can dramatically boost testosterone levels, so side effects are possible. Here are some of the ones that have been reported: headaches, upset stomach, and anxiety. I’m not a betting man, but if I was, I’d bet that the people who reported these side effects took Testogen on an empty stomach…don’t take it on an empty stomach. With more testosterone production comes higher testosterone levels, and your body needs to be prepared to handle all of the new testosterone. It is after all a hormone, so very high levels of it can cause mild side effects.

Testogen complaints & praise (Testogen reviews from real users)

We took a look at some of the verified buyer reviews on Amazon to get an idea of what real users of Testogen are saying. Generally with dietary supplements, you want to make sure to check Amazon verified buyer reviews, as those are usually the most trustworthy. We discovered a total of about 320 Testogen reviews…let’s analyze some of the data we found.

40% of users rated it 5 stars out of 5, which is a pretty impressive mark. An additional 20% of users rated it 4 stars out of 5, which is again highly impressive. Many people said they noticed it helped them experience muscle gains AND burn stubborn body fat. This is a bit surprising to me because I know from personal experience that Testogen can help with lean muscle mass, but I didn’t know it had the ability to burn stubborn body fat as well (such as areas like the stomach, love handles, etc.).

On the flipped side, about 15% of users reported a negative experience with it. There are a few outliers, but the vast majority of customer reviews reported positive results, which is very encouraging. This information helps support our theory that Testogen is effective, which was initially primarily based on analysis of the SFP (supplement facts panel).

Last but not least, as thesupplementreviews.org’s main testosterone booster reviewer and analyst, I felt compelled to try Testogen myself. My training as a Certified Nutrition Coach as well as a Nutrition & Wellness Consultant allowed me to gain a ton of knowledge regarding how nutrients and ingredients work in the body, plus I became very proficient in SFP analysis.

I touched on my experience with Testogen before, but I’ll recap it again here. As I expected, Testogen kicked in almost immediately in terms of enhancing my performance in the gym, promoting lean muscle growth, and skyrocketing my energy levels. I attribute the short term effects and results to the heavy dosage of D-Aspartic Acid, which is a naturally ocurring amino acid that is clinically proven and typically fast-acting.

Over the longer term period of three months, I was able to make very significant progress in terms of my performance in the gym, my lean muscle growth, and I was really happy with my muscle gains overall. I gained roughly 15 pounds of lean muscle mass over three months and have noticeably less body fat. My abs are much more defined, my arms are bigger, I was able to lose weight in the areas I wanted to (stomach fat, etc.), and I just feel better overall…I’m about to order more Testogen tonight.


Is Testogen worth it? Our Testogen test booster review conclusion

Testogen has one of the most potent and comprehensive formulas on the market. There just isn’t anything negative to be said about it in my view…it contains all of the vital key ingredients, uses large dosages, and has an exceptionally high overall potency.

Plus, let’s not forget that feedback we analyzed from the customer reviews and my personal experience. The vast majority of users (including myself) are confirming the conclusion we came to on the formula, which is that it’s likely to be highly effective. Suffice it to say, Testogen certainly earned its spot as one of our top three best testosterone boosters.



Is Testogen safe?

In order to answer this question, we can use the same reasoning we used when discussing Testogen side effects…the use of a 100% natural, herbal formula makes Testogen safe for most people. The whole point of natural test boosters is the fact that they’re a safe alternative to synthetic methods of fixing low testosterone levels.

Is Testogen legal?

Yes, Testogen is 100% legal. It contains no synthetic ingredients, no anabolic steroids, and nothing else that would cause the supplement to be rendered illegal. As I said earlier, it strictly contains 100% natural ingredients. There’s nothing sketchy in it whatsoever. With that being said, many people ask me is Testogen FDA approved, and that answer is no. The FDA will never approve natural testosterone boosting supplements like Testogen because they want people who have low testosterone to do testosterone replacement therapy instead.

Does Testogen cause hair loss?

No, Testogen is highly unlikely to cause hair loss. Hair loss is a side effect that is commonly associated with synthetic drugs like anabolic steroids, which are terrible for you and cause a wide array of side effects. Testogen is a natural alternative to dangerous drugs like steroids, and therefore does not cause the same side effects.

Does GNC sell Testogen?

No, you can not find Testogen in stores anywhere. It is strictly available online, and we strongly recommend only buying it directly from the manufacturer. Places like Amazon will overcharge you for it, so be sure to buy it directly from the company website.

When should I take Testogen?

We typically recommend taking Testogen or any testosterone booster in the morning after you’ve had a meal. Taking it too late in the day may cause some insomnia, and taking it on an empty stomach may cause some side effects. Therefore, we believe taking it in the morning after eating is best.

Does Testogen have an estrogen blocker?

Yes actually, it does. The old version of the Testogen formula did not contain an estrogen blocker, but they recently added Stinging Nettle Root Extract to the formula, which is believed to be an effective estrogen blocker.
