We’ve rounded up five of the best testosterone booster supplements that are going to make you feel great, and we’ve included the top characteristic of them all in their titles. You will learn these supplements’ side effects, ingredients, benefits, and more when you read our review.

Why Should You Consider A Testosterone Booster? 

As us guys get older, the levels of this hormone decrease. We peak in our 20s and 30s, and then the downward slide begins. 

Your body functions that depend on testosterone decline, too. For instance, muscle growth slows down, body fat is harder to lose.

However, a testosterone booster helps reduce such symptoms and keeps levels where they were in your younger days. This, in turn, helps you feel more masculine and confident in yourself.

This is where Prime Male comes in. This supplement can help get the testosterone levels in your body up by over 40% after just 12 days of usage, so says their website.

How does It work? 

The supplement works in three ways. 

First, it increases the production of LH, or luteinizing hormone. The Leydig cells, in particular, are responsible for the production of testosterone, so by stimulating the LH hormone, those cells are stimulated, and more testosterone is produced.

The second thing this supplement does is to stop the production of prolactin and estrogen. These hormones are for females only, and the suppression of these hormones leads to greater testosterone availability.

Third and lastly, sex hormone-binding globulin is lowered, and by lowering this, more testosterone makes its way into your system. For more information, check out our full Prime Male review.

3. Testo-Max – Natural Alternative to Steroids

testo max testosterone booster

Steroids are something of a touchy subject. Most of us guys have probably thought about using them.  After all, they DO work… but it comes at a very high price and often at the high cost of your well-being and health. 

Thankfully, a solution is here, and it’s natural and safe. 

It is the legal substitute to Sustanon, an anabolic steroid used to treat testosterone deficiency in men. It’s made by CrazyBulk, a USA based sports supplement company.

Indeed, this is an excellent product for guys that want to feel like themselves again. Here’s what other guys experienced with TestoMax:

  • Increase in Stamina
  • Increase in Energy
  • Easier recovery after working out
  • Greater muscle mass
  • Greater strength


  • Panax Ginseng– Increases the numbers of luteinized hormones, boosts strength, and improves cognitive function and development.  40mg
  • Vitamin D3: Increases the amount of testosterone the body makes could even double the testosterone levels in the body. 52mcg 
  • Zinc-  Fast-tracks testosterone production and increases the number of red blood cells released by the body. 10mg
  • Fenugreek Extract-Improves the alertness, and sperm count of men as well as testosterone levels. 40mg
  • D-Aspartic Acid- Increases your athletic performance and increases the strength and size of your muscles. 2352 mg

How does It work? 

Thanks to the D-Aspartic acid, healthy production of testosterone is promoted. LH, or luteinizing hormone, is released, which increases testosterone production by stimulating the Leydig cells.

Combine this with a healthy diet and workout routine (especially one that focuses on strength training), and you will find that the higher levels of testosterone in your body help you build muscles and increase your stamina and strength.

How to Use? 

You will take four pills in the morning with your breakfast, even if you are NOT working out that day. You will take it for two months and then go for 1.5 months without it- otherwise known as cycling the supplement. 

By following the recommended dosage, it will take just a few weeks before you are able to see results. Thanks to the ingredients being natural and safe, you can take this without worry.  

Some users did report side effects such as headache, gas, and upset stomach, so make sure to take as directed.

TestoFuel is another very popular male supplement. This is for the guys who want to build muscle and build it quickly.

Ingredients Found in Natural Testosterone Boosters

As you can see, the ingredients to these testosterone boosters were pretty similar to one another. This is because they really work, and they are chosen because they address specifically an area of testosterone production that isn’t doing so well. 

For example, perhaps you need more LH, or to suppress estrogen, to get those T levels up again. 

Many of the boosters we featured on our review included ingredients like D-Aspartic Acid, ZMA, or Fenugreek.

Even if you do not choose any of the products listed here for your own purposes, we encourage you to look for these ingredients as you shop. 

ZMA combines Vitamin B6, Magnesium, and of course, Zinc. These are great at increasing T levels in the body and improving your sleep.

Having great sleep is essential for your good health. You will be well-rested and ready to handle whatever the day throws at you, perform well at the gym, and have a better attitude as you take on the day.

Sleep also helps you avoid overeating and reduces cortisol, the stress hormone. 

How to Tell If Your Testosterone Is Low?

There are a few signs that the T levels in your body have been slowing down.  In this section, we will discuss a few of these, which can help you decide if a T booster is right for you. 

  1. Body Fat Increase- Low T Levels mean you may experience an increase in body fat. Some men experience gynecomastia or enlarged breast tissue, thanks to estrogen and testosterone imbalances in their bodies.
  2. Losing Muscle Mass- Testosterone is needed for muscle mass. Low T levels mean you lose muscle mass and a decrease in muscle-building activity.
  3. Changes in Mood- Testosterone has an impact on mood. Men with low T levels may experience depression, become irritable, or even lack focus. Testosterone has a massive impact on both the physical and mental state of men.
  4. Smaller Testicle Size- Men with low T levels may notice a size decrease in testicles even when it is not cold. The scrotum may feel softer also.

 How Do Testosterone Boosters Work?

In this section, we will look at three ways in which Testosterone boosters help men increase their T levels. 

Lowers Estrogen and Prolactin Levels– These are two female hormones that men do have, but the body mostly suppresses them. If they are not suppressed, which can happen, they inhibit the effects of testosterone. It prevents men from feeling their best.

Estrogen rising in the body of a male is thanks to the enzyme aromatase. It stimulates estrogen to levels so high that testosterone production reduces drastically. T boosters inhibit aromatase production. 

Raises Free Testosterone Numbers: T boosters work by increasing levels of testosterone already in the body. There are always sufficient testosterone levels in a man’s body, but only so many of them are available at one time, thanks to Sex Hormone Binding Globulin.

When the sex hormone binds to SHBG, the anabolic effects can no longer be used. Thus, it becomes useless to a man. T boosters stop the release of the SHBG so that it can set free any born testosterone and let the male’s body use it.

Normalizes Testosterone Levels– The body is capable of producing testosterone naturally, but this goes down as age increases. The endocrine system and the brain are responsible for helping produce testosterone. To help them out, natural ingredients can be used. These are not found in foods we eat, so supplements crafted with these ingredients can help. 

Benefits of Taking A Testosterone Boosting Supplement 

Curious about what can happen when you take a T booster? Here are some benefits: 

  • Increased Bone Strength: Increased testosterone levels will help you maintain healthy bones. You will be able to work out harder, which helps keep bones healthy and increase their density. The ingredients contained in these boosters include ones that help bones grow strong.
  • Better Mood: Imagine not feeling tired, irritable, or depressed. These are all symptoms of low T levels, and they are not present in males whose testosterone has declined with age. Taking a testosterone booster may help improve your mood.
  • Building Muscle: T boosters are great at increasing muscle mass when used with proper diet and exercise. They lower fat levels and increase energy levels. A T booster could help guys that want to build muscle and lose body fat.
  • Promotes Healthy Heart: If your heart is healthy, blood can get everywhere it needs to go. With enough blood going where it needs to be, muscles can work at peak efficiency. Testosterone helps boost the production of red blood cells in the bone marrow.

Any Side Effects?

With these T boosters, you can generally count on your experience is positive. The ingredients are natural and well researched. 

However, there are some side effects that have been reported you should know about. If you experience any of these, do stop using and speak with a healthcare professional.

Too Many Red Blood Cells: It is a good thing that the body produces a larger amount of blood, as this means you can perform better at the gym, among other benefits. 

However, too much blood leaves the body open to clots forming, and this may lead to ailments such as pulmonary embolisms, which can be fatal.

Prostate Growth: Known as benign prostatic hyperplasia, this is a noncancerous growth of the prostate which can happen when using a T booster. If you already had prostate cancer, a T booster could speed up the growth of cancer.

Exacerbated Acne: If you are a man who already struggles with acne, you may wish to talk to a dermatologist before using a T booster. Escalations in the condition have been reported. 

Exacerbated Sleep Apnea: There is a relationship between low T levels and sleep apnea, and it could get worse if your body negatively reacts to the T booster. 

Read the Research

It is no secret that T levels go down when men get older. So, it’s perfectly normal and natural that guys want to prevent this from happening. 

Thus, they turn to natural T boosters to help out. Thankfully, the ingredients are all backed by scientific studies that show their efficacy.

That being said, a lot of research is still being conducted on these and other top testosterone boosters to see how they work, and how they are affecting men who take them. They are always being improved as time goes on. 

That being said, we encourage men to read carefully about the testosterone boosting supplement they are most interested in and schedule an appointment with their doctor before using to ensure no negative side effects occur as a result of interaction with the medication they are taking, or to simply get an opinion from a trusted professional.

Take the Recommended Dosage

Every T booster you purchase has a label prominently displayed that tells you how much of the supplement you should take. This will vary from booster to booster, but you should stick to the recommended dosage and follow it to the letter.

It may be tempting to take more to get faster results, but such an action could lead you to feel sick, unwell, or even experience negative side effects.

Conclusion: Should You Use a Testosterone Booster?

If you are a male aged 18 and up and want to feel and look your absolute best, consider using a T booster to help out.

The benefits of these boosters are numerous. For starters, it is comforting to know that the ingredients are natural and safe. Second, the supplements are good for guys of all ages, especially men who are in their middle ages but looking to feel their best again. 

With these in mind, we recommend starting with either Prime Male or Testogen, as they will be the most effective from the beginning.

Another “pro” is that the supplements can be ordered online and sent to you anonymously. Some companies we reviewed noted their items were sent in plain packaging so that you can remain discreet about your purchase.  

Given the world’s current state, it is much safer to have items sent to you instead of having to go get them yourself.

Our bottom line is, yes- testosterone boosters should be on your radar if you feel your T levels are low. Make sure to research the one you like carefully and talk to a healthcare professional to ensure your safety. Best of luck and enjoy feeling like yourself again!
