We decided to do a Testogen review because this male supplement promises to increase testosterone levels, energy, and focus using all-natural ingredients.

After three months of testing and back-and-forth consultations with a urologist, here’s what our research and testing revealed.

What is Testogen?

Testogen Supplement

Testogen is a natural testosterone-boosting supplement designed to naturally increase the amount of testosterone in your body.

Our first-hand experience found that it may also help you become sharper and less irritated, among other benefits.

As our bodies age, testosterone levels naturally decrease. This can leave you feeling older than you actually are.

Another purported use of this product is to help you lose excess body fat and build lean muscle mass, with a fair few happy customers claiming it does just that.

All of those dietary supplements' ingredients are then contained in simple capsule form, making it a convenient alternative to testosterone in your body .

  • All-natural ingredients combined together in FDA-approved facilities, with no artificial colors or flavors
  • 60-day money back guarantee if not completely satisfied
  • Helps build muscle growth and helps burns excess fat
  • Increases libido, thus increasing sexual desire and improving sperm quality
  • It is a relatively expensive product
  • Can cause side effects (on rare occasions) if allergic to any ingredients

Testogen Benefits

Testogen contains a blend of natural ingredients that are scientifically proven to boost testosterone levels naturally, making it effective for testosterone replacement therapy.

But with added nutrients, users can expect other benefits within just two weeks, such as:

  • Increased energy and stamina
  • Lower fatigue levels
  • Improved recovery times
  • Enhanced lean muscle mass
  • Better libido
  • Clearer mind
  • Better focus
  • Lower body fat

Any Side Effects?

Side effects appear to be relatively rare, but this natural testosterone booster has some potential side effects that should be addressed in this Testogen research. It applies even when used for testosterone replacement therapy.

  • Zinc - It’s possible that when using zinc, which Testogen contains high amounts of, you may experience nausea, flu-like symptoms, and stomach pains [1].
  • Fenugreek - Although fenugreek often does not have any side effects, some people may be allergic to it, which can cause reactions such as stomach pains, diarrhea, or constipation.
  • Bioperine - If you’re allergic to black pepper, Bioperine is made of it, and thus, it may be best to avoid it. Some side effects may be nausea, gas, diarrhea, and respiratory problems.

Testogen Ingredients

Supplement facts of Testogen

Now, let's find out how each ingredient works and how much of each you get in one serving.

1. D-Aspartic Acid (2352 mg)

Its main purpose is to promote the production of luteinizing hormone, which then stimulates testosterone production.

A study from Reproductive Biology and Endocrinology has shown that daily supplementation of D-aspartic acid boosts testosterone levels after 6 days, with an up to 42% increase after 12 days [2].

Testogen has more D-aspartic acid per serving than other similar dietary supplements on the market, and our test results showed this could help you lose more weight.

2. Magnesium (200 mg)

The amount of magnesium per serving of Testogen is enough to support healthy testosterone production, as higher free testosterone levels are linked to higher magnesium levels.

Studies show that men receiving daily magnesium supplementation had an increase in free and total normal testosterone levels, and this is especially true for active men who exercise regularly [3].

3. Fenugreek Extract (40 mg)

Fenugreek stimulates testosterone production and increases strength and endurance levels.

Men aged 50 showed an increase in testosterone levels by up to 46% after 12 weeks of daily fenugreek supplementation. Aside from that, they experience significant improvements in terms of energy, strength, endurance, overall mood, and libido [4].

After two weeks of taking Testogen, I started to feel some changes in terms of energy, endurance, and strength. There was also less fatigue during my training sessions, so that's a really good sign.

4. Nettle Leaf Extract 4:1 (40 mg)

Certain compounds in nettle leaf extract called ligands prevent the binding of SHBG or sex hormone binding globulin to testosterone. This increases the amount of free testosterone in your body, which does all the work [5].

Research shows that ligands in nettle leaf extract prevented the sex hormone binding globulin from binding to DHT, a type of male hormone, by up to 67% which then boost free testosterone levels [6].

5. Korean Red Ginseng Extract (40 mg)

Our findings indicate that men who have been taking Korean red ginseng extract showed an increase in testosterone levels as well as luteinizing hormone, which boosts testosterone production [7].

By the end of my third month of taking Testogen, I was amazed by how my body and mind were transformed. I felt more energetic and focused than before, which helped me a lot since I really struggled with my overall mood.

6. Vitamin B6 (20 mg)

Together with zinc and magnesium, vitamin B6 is also linked to testosterone production, as vitamin B6-deficient men have low testosterone levels [8].

During the next 2 weeks of consistent use of Testogen, I noticed that my muscles got toner, and I generally felt stronger as I was able to lift heavier weights at higher reps than before.

I also had shorter recovery times in between sets, and I definitely had an increase in energy and endurance that made it possible for me to get more out of my training sessions.

7. Zinc (10 mg)

Zinc acts as an antioxidant to prevent oxidative damage to Leydig cells, which are cells that produce testosterone.

A study reveals that daily supplementation of ZMA, which contains zinc, magnesium, and vitamin B6 in a span of 8 weeks, increases free testosterone by up to 33% [9].

Testogen uses zinc citrate, which our tests proved to have better absorption than other forms like oxide [10].

8. Boron (8 mg)

Boron is an essential mineral to increase lean muscle mass and bone strength, but it also converts total testosterone to free testosterone, which contributes to healthy testosterone levels.

Aside from testosterone metabolism, our experiments also show that it can decreases estradiol, a type of estrogen, meaning boron can help significantly boost testosterone levels.

Boron also improves the absorption of vitamin D3 and magnesium, which are both in the Testogen formula [11].

9. Bioperine® (5 mg)

Aside from boosting energy metabolism, Bioperine® also increases the bioavailability of ingredients in Testogen by up to 30% [12]. It's added to enhance the effectiveness of Testogen to give you faster and better results, which I can confirm from personal expereince.

10. Vitamin D3 (50 mcg)

This vitamin is known to help with bone health, but like zinc, it's also involved in testosterone production. Studies link vitamin D to testosterone levels as men with enough vitamin D have generally higher testosterone levels.

In a study of men with vitamin D deficiency, doubling daily vitamin D intake increased free testosterone by as much as 20% [13].

Testogen uses cholecalciferol or vitamin D3 which has been proven more effective than other forms.

11. Vitamin K1 (20 mcg)

Although vitamin K is a fat-soluble vitamin essential to blood clotting and may improve bone density, its primary role in Testogen is to aid vitamin D absorption [14].


Does Testogen Work?

Yes, Testogen does work. Based on my experience for the last three months, I can confirm that it’s effective.

It optimized my energy, strength, and focus, which helped me perform better at the gym and develop more toned muscles.

Clients also sent me their feedback, and they reported experiencing similar results.

For many people who have purchased the supplement, it has worked wonders.

If you’re experiencing signs that could be related to low testosterone levels, Testogen may be the way to seize the day and claim back that lost drive.

Proper Dosage And How to Take Testogen

The recommended dosage is four capsules per day, and you should aim to take them first thing in the morning. During our testing phase, we took a few different approaches to validate this recommendation.

First of all, two people on our testing team took all four capsules in the morning, with breakfast still a few hours away.

Another group took the four capsules with breakfast. And then, a third group took one capsule at four different times.

Based on our test results and comparing the effects after six weeks, we found that taking them with or without breakfast worked best.

But if you spread out the dosage over the day, it’s a bit slower to see the major benefits.

Is Testogen Safe?

Yes, Testogen is safe to use. The organic ingredients included in Testogen are tested in FDA-approved facilities.

There are also scientific studies available on their official website which support the effectiveness of the product. Our testing encountered no negative effects at all.

Testogen is also safe for long-term use to increase low testosterone levels in a completely natural way. However, you may experience an occasional plateau after several months of usage as a result of your body adapting to the supplement.

When Should You Consult a Doctor?

You should consult a doctor before taking Testogen if you have a major testosterone deficiency that is being treated with steroid medication like testosterone replacement therapy.

First of all, even safe herbal ingredients like in Testogen could have an interaction with medication. You could end up nauseated or even counteract the medicine you’re taking, which is never a good thing to do.

The other thing to keep in mind is that Testogen could further boost testosterone levels. And your doctor should be aware of this in order to fine-tune any other medication you’re taking.

Testogen: Before and After

After taking the Testogen for almost 3 months, I noticed a significant difference in how I perform during workouts and feel throughout the day.

It took around 2 weeks to start to feel some changes in terms of energy, endurance, and strength. There was also less fatigue during my training sessions, so that's a really good sign.

During the next 2 weeks of consistent use of Testogen, I noticed that my muscles got toner and I generally felt stronger as I was able to lift heavier weights at higher reps than before.

By the end of the last week of my third month, I was amazed by how my body and mind were transformed in a short period of time. I felt more energetic and focused than before, which helped me a lot since I really struggled with my overall mood.

I had shorter recovery times in between sets, and I definitely had an increase in energy and endurance that made it possible for me to get more out of my training.

Where Can You Buy Testogen?

You can buy Testogen on their official website, where you can get authentic products at a discounted price with free shipping.

But you can also buy Testogen from the company's authorized sellers on Amazon.

Shipping and Returns

Testogen offers worldwide shipping to almost anywhere in the world, except the ones on this list.

All orders have free worldwide shipping, regardless of amount, quantity, and location. In my case, it took about three days for the package to arrive.

For orders of 2 bottles or more, Testogen provides a 100-day money-back guarantee, provided that you have used the product for at least 50 days.

Brand Reputation and About The Company

Testogen is made by a company called Health Nutrition Limited, which is a well-known brand in the sports and nutrition supplement space.

It specializes in products that focus on improving free testosterone levels but also has some good fat burners.

Having looked at online Testogen reviews and forum comments about the company’s other products, it definitely looks like there is a lot of trust in this brand.

People regularly comment about the great customer service and the benefits they are getting for weight loss, muscle growth, and general health.

Testogen User Reviews

Many customers are raving about Testogen online. Here are a few Testogen reviews that stood out to us.

“I have a lot more energy during the day and especially for workouts. I feel like I’m in my early 20s again.”

-Brent, USA

“I’m feeling better, leaner, stronger, and my friends, family, and trainer have noticed the changes, too.”

- Mitch, AUS

“A better alternative for me than testosterone therapy. Testogen is helping me achieve my strength and muscle goals.”

- Greg, USA

“Testogen changed my life. I feel amazing. By the end of the second week I could already start noticing a difference.”

- Jason, USA

Testogen Alternatives

Here are three other products that may help to increase free testosterone levels, and we’ve done extensive testing on these as well.


This herbal supplement was mainly designed to counteract the effects of low T-levels that naturally happen with age, like low energy levels, weight gain, and loss of libido.

But the same effects that get you more active in bedroom activities will also contribute to athletic benefits like muscle growth and faster training recovery.

We spent many weeks testing Aphro-D with clients and saw some impressive blood test results.

When we compared the before and after T-levels, there was an increase of over 25%, which is pretty impressive for a natural supplement.


TestoFuel is another natural supplement that aims to support healthy testosterone levels with amino acid ingredients like D-aspartic acid and minerals like zinc.

The formula is highly focused on only sourcing proven ingredients, and we found that it’s very easy on the stomach, even if you take it while fasting.

But in our experience reviewing TestoFuel we found it can also help with general improvements in health and mood.

Prime Male

After reviewing Prime Male, it became one of our recommended natural testosterone boosters for athletic performance and muscle growth.

It’s the leading dietary supplement we recommend for vegan athletes, as it only uses plant-based ingredients.

Overall, testosterone concentration in our test subject went up, and we were able to verify this with blood and saliva tests.

Diet and Lifestyle Factors Impacting Testogen Efficiency

Diet and lifestyle significantly influence the Testogen's efficacy. A balanced diet rich in healthy foods, coupled with regular exercise, especially strength training, enhances testosterone production.

Stress reduction and adequate sleep are also crucial, as they naturally boost testosterone levels [15]. Combining these lifestyle practices with Testogen ensures optimal results, synergistically elevating testosterone for improved health and vitality.

I can confirm this from personal experience with several of my clients who were able to transform their health and fitness efforts with this combination.

Is Testogen Considered Anabolic Steroids?

No, Testogen is not considered anabolic steroids. Testogen uses all-natural ingredients to boost testosterone levels in your bodies. Due to these ingredients, it is seen as one of the safest ways to treat low testosterone levels.

Anabolic steroids are often synthetic substances, and Testogen contains only natural ingredients. It is therefore not anabolic steroids, but a natural and organic alternative.

How Long Does Testogen Take To Work?

Testogen takes around two weeks for results to begin to show with daily intake. This can be decreased by increasing the number of tablets taken every day.

What Will Testosterone Booster Do for Me?

Testosterone boosters for men aim to boost and bolster the amount of free testosterone in your body. This is supposed to have a wealth of benefits including more energy levels, sexual stamina, and faster recovery at the gym.

Organic boosters such as Testogen use natural and scientifically proven ingredients to boost testosterone production such as Korean red ginseng and nettle leaf extract.

Should I Take Testosterone Booster Before My Workout?

No, it’s not necessary to take a testosterone booster before your workout.

Testosterone boosters are a male hormone enhancer, not a protein shake. Even if you are taking them to improve your progress and recovery time, you do not need to take them at a specific time for maximum gains. Treat them more as multivitamin capsules that are best consumed during the morning.

Can You Overdose on Testosterone Booster?

No, you can’t overdose on a testosterone booster.

That would be difficult since they are testosterone supplements designed to increase the production of the hormone and not the actual hormone itself.

It's best to stick to the recommended dose to prevent any side effects. The effects of excess testosterone are hard to spot in adult males, but if you’re worried, you should seek a doctor’s advice immediately. They can help guide you with testosterone replacement therapy.

What Are the Symptoms of Low Testosterone?

Some common symptoms of low testosterone levels include fatigue, low libido in male reproductive system, low sexual performance, low motivation, weight gain, stubborn belly fat, and muscle degeneration.

While it's good to take testosterone blood tests to make sure that you have low testosterone levels, it can sometimes become irrelevant since ranges for healthy testosterone levels for a particular age are quite large.

The best thing to do is to pay attention to your performance and mood before testosterone treatment. If you think your performance or mood has dropped, it may be a sign to take testosterone booster supplements to help you get back to your old self.

Is Testogen legal?

Yes, Testogen supplements are legal. It is made from completely natural ingredients that claims to boost testosterone production. However, there may be some differences among countries where certain herbs are banned, so it’s important to check your country's regulations if you are ordering from overseas.

Do I Need to Make Any Changes to My Diet?

No, you don't need to make changes to your diet.

Testogen is a natural and organic testosterone booster supplement that helps you make the most of your current diet. Since testosterone levels are correlated with how proteins are used by the body, taking Testogen can help you build muscle mass without going on crazy diets.

However, it's still recommended to have a healthy, well-balanced diet to get the results you want faster.

Is Testogen FDA Approved?

No, Testogen is not FDA-approved but is manufactured in an FDA-approved facility. The FDA does not regulate dietary supplements like it does medications, so purchasing testosterone supplements from a reputable source is critical to ensure you are getting a safe product.

Our Verdict on Testogen

If you’re experiencing fatigue, weight gain, low libido, high excess fat, and muscle degeneration due to low T levels, based on the data presented in this Testogen review, I believe this product can help address your health challenges.

With its potent lineup of natural ingredients, I and many others have experienced a boost in energy, strength, and endurance.

These dietary supplements also improved my recovery times and aided my muscle development.

Testogen is a product that stays true to its promises. And for that, I have no qualms about recommending it to anyone looking to boost their testosterone.
