Best Testosterone Booster Supplements

If you’re thinking about giving your testosterone levels a leg up, here are the best testosterone boosters that you can buy right now. Read on for a detailed review of how they work, what they do well, and what sets them apart from other supplements.

#1. TestoGen: Strongest T-Booster

testogen lipido performanceThe undisputed leader in testosterone boosters, Testogen has cemented its place with medical-grade ingredients, the best production facilities, and the highest-quality ingredients. Whenever you get a bottle of Testogen, you’ll always be sure that you’re getting nothing but the best stuff ever put in a testosterone booster.


Testogen has a “Triple Action Formula” of the key compounds that help your body produce testosterone, and other ingredients that help the product work better. These include:

D-Aspartic Acid

This amino acid starts testosterone production in the body, aside from increasing sperm production. It also helps increase muscle mass, improve libido, and improve your mental performance. With plenty of D-Aspartic acid, your body can increase testosterone levels steadily and consistently!


Zinc is responsible for processes like protein production and cell division, which determine our muscle mass and helps improve our natural strength. Your body needs a consistent amount of zinc to metabolize the nutrients you get from food, so having a source of zinc can help you avoid weight loss and a weakened immune system.

Vitamin D

With so many of us spending most of our time indoors, a healthy dose of this sunlight vitamin is just the thing you need to support and boost testosterone production. It allows our bodies to process other ingredients needed to grow muscle mass and increase energy levels, aside from making us more resilient to sickness and sudden changes in our bodies.

Other Ingredients

Aside from the 3 core compounds, Testogen also comes with natural extracts from the fenugreek plant, selenium, and Tribulus Terrestris. These ingredients support the active components of Testogen, allowing your body to cope better with the changes brought about by a boost in your testosterone levels.

Testogen works by increasing your body’s testosterone production, using its active ingredients to send signals for your body to produce hormones in earnest. The synthetic and natural ingredients in Testogen work to improve hormone production, allowing you to both create and use existing testosterone in your body better.

The other ingredients in Testogen also help boost testosterone production by working in sync with the active ingredients. They help your body cope better with the increased levels of hormones in your body and do a great job in boosting the already potent effects of the “Triple Action Formula”.

Dosage & Beginner Advice

One serving of Testogen is 4 capsules a day, as each bottle contains 120 pills for 1 month. Ideally, you should take 1 serving a day before you eat breakfast. This helps kick-start your testosterone production early and allows the active ingredients to support additional hormone production by utilizing the nutrients from the food you’ll eat.

For beginners, it’s important to check that your bottle of Testogen is the latest version. Unlike a lot of brands, Testogen always changes their supplement to account for the latest studies and research about testosterone production. That’s not to say that their older bottles won’t work, but the newer bottles will give you better results.

Overall, with its commitment to quality and its top tier ingredients, Testogen is one of the best testosterone pills on the market that you can buy right now. It gives you all the benefits of a testosterone booster like muscle growth and an increase in energy and libido, and also works well as an all-around male supplement!

With one of the highest concentrations of pure testosterone, TestRX is one of the heaviest hitters in testosterone boosters. If you want to see a steady improvement to your testosterone levels, this is the supplement for you.


The secret behind TestRX’s speed at boosting low testosterone is in its carefully selected and measured ingredients. Made in clinically approved facilities, here are some ingredients you’ll find in your bottle:

D-Aspartic Acid

This powerful amino acid is a key component in our body producing and boosting our testosterone levels. It can help add muscle mass, improve brain activity, and regulate things like sex drive and mood. With consistent use, D-Aspartic acid can greatly increase energy levels and natural strength.

Fenugreek Extract

Fenugreek extract supports the sudden increase in testosterone levels by stopping the excess hormone from turning into estrogen. Not only does this ensure that you get to use all the free-floating testosterone in your body, but it also helps increase your metabolism, helping you turn fat into muscle.


Aside from helping build strong bones, zinc also functions as a check against one of the key side effects of low testosterone like erectile dysfunction.

One warning: TestRX is strong stuff. This isn’t something that you should take if you’re new to the world of testosterone boosters. The formula in this supplement is like the one used for testosterone therapy, which can have bad side effects for people that don’t have to boost testosterone levels that much.

Aside from some minor side effects, TestRX is one of the best ways you can increase testosterone with fast and visible results. While this product is stronger than other testosterone boosters on the market, it’s one of the best supplements you can use when you need to boost low testosterone.

What Does Testosterone Do?

Let’s get this out of the way: testosterone is responsible for muscle growth, affects your sex drive and libido, and is found more in men than women. All of this is common knowledge, so what else do you need to know?

For starters, testosterone levels in our body is a key factor in making sure our bodies stay in one piece. Here’s a list of what testosterone can do for you:

  • Control red blood cell production
  • Regulates fat
  • Determines your sperm count
  • Boosts your energy levels
  • Increase your bone mass
  • Improves your cognitive function
  • Affects your mood

Testosterone isn’t just for men either: women need testosterone to increase their bone density, improve their ovarian health, and affect their reproductive system. Regardless of gender, testosterone is an important hormone that can help us adapt and grow with our environment.

Why Testosterone Levels are so Important

Now that you know why testosterone is so necessary, let’s move on to why testosterone levels can shift. First, it’s important to remember that our testosterone levels won’t stay the same for all our lives.

The body’s supply of testosterone peaks around puberty stays at a plateau for most men until 40 years old and starts declining from there. This isn’t a BAD thing – there are risks to having too much testosterone, as we’ll discuss later – but it’s important to note that this is the way things are SUPPOSED to go.

Several factors can affect this progression like genetics, injuries, and lifestyle habits. Even the time of day can play a role: testosterone levels spike during the mornings and decrease as the day goes on. That’s why it can be so difficult to pin down how much testosterone a man needs since the “normal” testosterone levels are hard to pin down between different men.

Testosterone levels don’t just affect your physical state: it also plays a role in your mental faculties. As an essential hormone to male development, having the right levels of testosterone can help you grow and develop. It also affects sexual performance, which has a drastic effect on men’s self-esteem and confidence.

So how do you know if you’re getting enough of it? A good way to check how your testosterone levels are holding up is to examine how your body responds when you have too much or too little of this hormone.

When You Have Too Much Testosterone

Many people attribute a high testosterone level to violent or aggressive behavior, but there’s actually no concrete scientific evidence that connects the two. However, there are several well-researched effects of high testosterone production levels in men:

  • Acne and overproduction of body hair
  • Liver disease and increased risk of heart attacks
  • Weight gain and heart muscle damage
  • Decreased mental faculty and irritability
  • High blood pressure and cholesterol
  • Increased likelihood of developing depression
  • Stunted growth, testicle shrinkage, and impotence

While an essential hormone, the body needs a consistent level of testosterone. Too much testosterone production causes the excess hormones to turn into estrogen, which can have a lot of side effects for the male body. Fortunately, having high testosterone levels isn’t a common problem among men.

When You Have Too Little Testosterone

Having low testosterone levels is a more common problem than you might think. According to that same Harvard article, more than a third of men over the age of 45 have lower testosterone levels than normal. And with the somewhat sedentary lifestyle changes today’s men face, low testosterone is more common than ever.

Here are some effects of having low testosterone levels:

  • Rapid mood swings and difficulty concentrating
  • Decreased energy levels and overall fatigue
  • A slowdown of muscle development and bone growth
  • Lowered libido and increased likelihood of impotence
  • Bodily changes like hair loss and gaining weight
  • Increase in breast size and reduced sperm count

Low testosterone levels can have a serious impact on your quality of life and can affect your self-esteem. That’s why you must look out for these signs.

How to Boost Testosterone?

There are two ways you can boost testosterone: testosterone therapy and testosterone-boosting supplements. Testosterone therapy is a medical procedure that’s used for men that need drastic testosterone boosting, either due to injury or pre-existing medical conditions. Unless you’re medically cleared, testosterone therapy might be a bit too much – and you wouldn’t need it.

But for men that need some help with their testosterone levels, a testosterone booster is a great way to bring your testosterone back to peak levels. Testosterone boosters can work in one of two ways:

  • It helps kick-start your body’s natural testosterone product, making you produce more hormones
  • It uses the already free-flowing testosterone in your bloodstream, so none of it goes to waste.

With prolonged use, your body will get used to the new way it uses your testosterone levels, allowing you to enjoy all the benefits of a steady and efficient supply of testosterone to draw on.

What About Steroids?

Something that will come up with boosting testosterone is whether steroids can accomplish the same thing. While steroids may have a more established reputation, the answer on which one to take is a little difficult.

While some steroids have been cleared for medical use, it’s often only approved of where no other options work as well. Getting your hands on legal steroids can be very difficult, and there’s no guarantee that any of the products you’ll see are the genuine thing.

Steroids are also very disruptive to your body’s natural rhythms. Since they’re made of synthetic chemicals that maximize results over method, manufacturers of steroids often gloss over the toll that your body can go through if you take steroids.

But unlike steroids, testosterone boosters work by changing your body slowly, instead of suddenly forcing changes on it. This allows your body to get used to the changes without having to catch and repair itself.

Another advantage that testosterone boosters have is that the side effects range from mild to non-existent. Steroids often cause enormous amounts of damage to the body when it changes it, but testosterone boosters don’t do that. So what’s the best testosterone booster on the market right now?

Before You Buy Your Testosterone Booster

Now that you know the best testosterone supplements you can get, you might be excited to get a bottle of your own. But before you look for a supplier, make sure that you clear things with your doctor about taking testosterone boosters.

This is important for two reasons. First, testosterone boosters are powerful stuff, regardless of which brand you pick. Second, there are some cases where even a testosterone booster won’t be enough.

Unlike most supplements, testosterone boosters have a drastic effect on your body’s development. Hormones are responsible for many of our body’s internal processes and taking testosterone boosters without consulting a medical professional can lead to some unexpected and unwanted results.

While testosterone boosters are a far cry from the formulas used in testosterone therapy or hormone replacement therapy, they share the same mechanism of action and can affect your body in drastic ways. This makes consultation with your doctor an important step you need to take before popping any pill into your mouth.

There are also times that testosterone boosters might not be enough. For cases of severe injury or pre-existing conditions, testosterone boosters might lack the effectiveness of medical-grade testosterone therapy. Using testosterone boosters when you might need something stronger is a waste of time and money.

Finally, testosterone boosters work best when your lifestyle can keep up with the changes. That means working out, changing your diet, and getting enough sleep. If you can’t commit to the changes that you’ll be making by taking a testosterone booster, then you’ll end up with subpar results, no matter which booster you pick.

Where to Get Testosterone Boosters

You should always know potential fakes or hoax products floating around. Always buy from the official manufacturers, since you’ll be sure that you’re getting nothing but the real deal.

You can also avail of perks like discounts, bulk shipping options, and returning promos if you end up buying from the same brand for a long time. This also allows you to skip out on charges like third-party resellers or premiums.

Frequently Asked Questions

Here are some other questions about testosterone and testosterone boosters that were a bit too short to make into their own section:

What does high testosterone do to a man?

How to test testosterone levels?

A blood test is the quickest and best way to test for your testosterone levels. Ask your doctor about the exact procedure you’ll have to go through. Since your testosterone levels fluctuate throughout the day, it’s difficult to get an accurate reading immediately.
