Best Testosterone Boosters Sold at GNC

You might be wondering, "Why would I go to GNC for my testosterone boosters?" Well, that's because you need to be certain that you're getting a good deal, for one thing.

GNC is a trusted veteran for supplements, with almost 90 years of experience providing top-notch products designed to improve your health.

Now without further ado, let's get into the best testosterone boosters that GNC offers so that you can pick out the best one for you!

1. TestoPrime - Best Overall

This is the best testosterone booster you can get, and that's because of what's inside it! TestoPrime comes packed with DAA and Fenugreek for more testosterone support.

Everything in this supplement is designed to help you reduce fat and pack on muscle mass, and they don't hide what's inside their product, either!

Other test-boosting supplements have "proprietary blends," which means they don't tell you exactly how much of each ingredient is inside their supplement.

TestoPrime is completely transparent with its ingredients and dosage. You can pick it up here.


  • No proprietary blends here
  • Doesn't require a prescription to pick up


  • It cannot be used if you have a medical condition
  • You need to visit their website for the right version

2. Testo-Max - Best Natural Testosterone Booster

This is an all-star from Crazy Bulk, also known for making muscle-building supplements.

Testo-Max is no different from the rest of the Crazy Bulk roster because it's designed to help you get stronger!

It does this by featuring some of the best ingredients around, like ZMA and D-Aspartic acid, which will help you work out harder and spend less time recovering. You can pick it up here.


  • Buy in bulk to save money
  • Higher recommended dosage


  • Only sold through their official website
  • It may need to be stacked for the best results

3. TestoFierce - Best For Muscle Gain

This is a completely legal and safe t-boosting supplement full of staple testosterone-boosting ingredients that have been proven to work.

TestoFierce has ZMA, DAA, and fenugreek extract to help you build muscle and lose weight, but it's not a miracle supplement. You still have to exercise to get the best results.

The only slight downside to this supplement is its extremely high recommended dosage, at 7 capsules per serving. It's a lot but worth taking for the muscle gains.

You can pick it up here.


  • Grow muscles and get stronger faster
  • Perk up with more energy


  • Premium option
  • The dosage might be too much for some

4. Nugenix Ultimate - Best For Males Over 40

There are several kinds of Nugenix out there, so don't get confused! This is the Ultimate version, which has different ingredients from its cheaper brethren.

Like some of the best testosterone boosters, Nugenix Ultimate sports a good amount of fenugreek extract to bolster its effectiveness.

The science behind this testosterone booster is a specific protein called the sex hormone-binding globulin, also known as ShBG.

The fenugreek within Nugenix Ultimate pairs with ShBG for a surge of testosterone. You can pick it up here.


  • Very high recommended dosage
  • Clear and transparent about their blend


  • Pricier than some of its competitors
  • Missing a few of the best testosterone-boosting ingredients

5. TestoFuel - Best GNC Testosterone Pills

This is the final testosterone booster here, and it features a unique ingredient: oyster extract! TestoFuel uses oysters as a second source of zinc and has plain zinc.

As a testosterone support supplement, this booster doesn't contain any testosterone but rather ingredients that will push your body to create more testosterone.

Another plus for this supplement is its approachable recommended dosage. The manufacturer suggests taking 1 pill with food 4 times a day.

You can pick it up here.


  • Packed with essential vitamins and minerals
  • Great way to increase natural testosterone


  • It can only be found on the official website
  • It might take longer to see results

What Is a Testosterone Booster?

As the name says, testosterone boosters increase the amount of testosterone your body has to work with. It's also helpful to think of them as "testosterone support."

They do this by going straight to the source: your blood. Taking the best testosterone boosters will cause your body to produce more testosterone within your blood.

what is a testosterone booster

This will let you enjoy all of the benefits of masculinity, like increased strength and an improvement in your sexual performance.

Don't think that only men will benefit from higher t-levels, either! T-boosters can also help women who are experiencing a lower sex drive.

There's another thing: test boosters are usually sold as over-the-counter medicines, so you won't need a prescription to get your supply.

How Does the Testosterone Booster Work?

People on testosterone replacement therapy run the same risks as people who misuse anabolic steroids. These include side effects like being more hostile, testicle shrinkage, and more.

Unlike what we've mentioned above, testosterone boosters attempt to stimulate your body's natural testosterone production.

While it's true that your levels of testosterone will naturally go down with time, that doesn't mean you have to suffer the effects of old age.

Thanks to a natural blend of ingredients, t-boosters can help you build lean muscle and melt off your fat no matter how old you are!

Some t-boosters have ingredients that will also increase the free testosterone your body has to work with.

What Are the Common Ingredients Used in Testosterone Boosters?

Most testosterone boosters will come with an ingredients label, which might seem like nothing to you.

We've listed a few common testosterone support mainstays for you to look out for!

testosterone booster ingredients

To help you find the best testosterone boosters, make sure that you see some of these ingredients on that label:

  • Maca root: Maca is a plant that has been described as "Peruvian ginseng." As that nickname implies, this plant has seen lots of use in Peru as traditional medicine.

Lately, it's become a mainstay in t-boosters because of its positive effect on sex drive. The root is the most important part of this purpose, and it's often powdered and mixed into foods.

Maca root has also been shown to help perk people up, both in terms of energy levels and their mood. Plus, it's safe to use and has a pleasantly sweet taste!

  • Tongkat Ali: This ingredient is also known as LongJack or Eurycoma. It's used in health supplements because of its testosterone-boosting capabilities.

Tongkat Ali is packed full of antioxidants that help your body repair itself and lower your stress levels at the same time. This makes it ideal for muscle recovery after heavy workouts.

  • Fenugreek seed extract: While fenugreek is normally a delicious seasoning, it's used in testosterone boosters to help increase your t-levels.

The fenugreek seed extract used in Nugenix Ultimate is refined until they become saponins.

These saponins mimic the molecular form of a steroid hormone without being either hormones or steroids.

The saponins help you produce more testosterone within your body by binding with an important protein found in your blood.

  • Horny goat weed: Also known as Barrenwort, these leafy plants are a staple ingredient in male enhancement supplements. They're mainly used in t-boosters to treat erectile dysfunction.

But they don't just stop at helping you get it up! They are also used to treat heart and blood problems, like high blood pressure.

Ensure you don't take horny goat weed if you're pregnant or if you have any hormonal conditions. This ingredient works similarly to estrogen, so beware!

  • D-aspartic acid: Also known as DAA, this is one of the most natural ingredients on this list. DAA is an amino acid, making it foundational for protein synthesis.

This amino acid is specifically involved in the body's production of testosterone, which is why it's earned a spot in the most effective t-boosters.

  • Tribulus Terrestris: Another traditional medicine, Tribulus has gained recent popularity for its health benefits.

Said benefits include a stronger immune system, higher t-levels, and an increased libido.

It's also known to improve your condition if you have heart problems and sexual performance issues.

  • Human Growth Hormone: Also known as HGH, this hormone is naturally produced by your pituitary gland.

You'll eventually have acromegaly if your body makes too much HGH while growing up. Taking test boosters will help you build muscle mass, but you won't get too big.

Fortunately, the amount of growth hormone used in t-boosters isn't enough to result in acromegaly. That's also why taking t-boosters isn't advised if you're under 18!

  • ZMA: This one is a formula of a few different testosterone-boosting ingredients. It stands for Zinc, Magnesium Aspartate, and Vitamin B6.

Every part of ZMA is great for improving your body's natural muscle protein synthesis, so athletes and bodybuilders mainly use it.

It's most effective on people deficient in Zinc and Magnesium, but going through the day will naturally deplete your minerals anyway.

Unlike other t-boosting supplements, ZMA is meant to be taken at night since it can make you drowsy. This also means you shouldn't take it if you're already on other medications.

It's more helpful to think of ZMA supplements as a sleeping aid in the world of t-boosters.

What Are the Benefits of Using a Testosterone Booster?

Taking a testosterone booster will directly increase your body's natural testosterone levels. This will come with various benefits, which we'll explain here.

benefits of testosterone boosters

Improved mental focus: A clear connection has been drawn between higher t-levels and better memory.

Higher levels of testosterone have also been shown to speed up how quickly you think and lower your risk of developing Alzheimer's disease when you get older.

You won't exactly develop photographic memory, but you'll be less likely to lose your things and forget what people have just said to you.

Better blood flow: Being testosterone-deficient can lead to an increased risk of heart problems. Fortunately, t-boosters are designed to combat this.

Taking a testosterone booster will improve your blood flow and the health of your heart.

With more testosterone flowing through your blood, you'll have more oxygen while exercising.

Lower body fat: The best part of taking a testosterone booster is the gains you'll see in your muscle mass. Testosterone is the most important hormone when it comes to building muscle.

Combing t-boosters with a healthy diet and a solid exercise regimen is a surefire recipe for more bulk and less fat!

Plus, you'll experience higher energy levels, which will let you work out for longer and perform more intense workouts!

Are There Any Side Effects of Using Testosterone Boosting Supplements?

When the science around muscle building wasn't so clear, people used to inject steroids directly to grow bigger muscles.

side effects of using testosterone boosting supplements

The problem with this method is that they were using anabolic steroids, which we now know are very unsafe. So they suffered side effects like premature hair loss and severe acne outbreaks.

Now, these testosterone boosters aren't like that at all! They're mostly made up of herbal ingredients plus the occasional growth hormone, which is purely natural.

You won't experience any side effects from these test boosters as long as you follow the proper recommended dosage while you're taking them!

But while these boosters are safe, the natural ingredients they're made from can cause a few side effects. These include headaches and nausea, plus dizziness.

Don't forget to ask a professional physician for their opinion before picking up a test booster!

How to Choose the Best GNC Testosterone Booster for Your Needs?

Picking up the best testosterone supplement will depend on a few key factors. These are dosage, the ingredients used, price, and how the supplement was made.

choose the best gnc testosterone boosters
  • Dosage refers to the number of ingredients that make up your testosterone booster. Every ingredient has a safe threshold to take in, so ensure your t-booster's blend follows this.

The ingredients are clear. You don't want to take in a supplement full of ingredients that don't have any research to back up their effectiveness.

  • Price is for practicality. Putting health aside, the best testosterone booster for you should let you achieve the results you want without the risk.

Hopefully, if you don't see much change after taking it, it comes with a money-back guarantee, so you don't waste your money.

Then there's how the supplement was made. Look for test boosters produced in GMP-certified and FDA-approved facilities to ensure your safety.

Finally, don't forget to notify your doctor and ask for their advice before you start taking any testosterone boosters.

How Can I Increase Testosterone in My 50S?

If you're going through andropause in your 50s, then t-boosters should work fine. But there are a few specific ingredients you should look for, namely Vitamin D, Zinc, and Magnesium. Taking more of these vitamins and minerals will net you a marked increase in your t-levels, letting you enjoy the strength of youth for longer!

Who Should Not Take a Testosterone Booster?

These supplements aren't for everyone. Before looking into test boosters, ensure you're at least 18 years old. None of these supplements are designed to be used by people under 18. You should also consult your doctor before looking into any testosterone booster here. If you have a medical condition, this might also affect your results.

How Long Does It Take for Testosterone Boosters to Kick In?

The first sign that your testosterone booster is working is an improved sex drive. This effect will kick in after roughly 3 weeks of consistent use, but muscle growth will take a little longer than that. After using a test booster for 3 to 4 months, you'll bulk up. Remember that no one's the same, so you might take longer to see the effects.

What Is the Best Testosterone Booster for Men Over 70?

Senior citizens will have a tough time increasing their t-levels, but it's not hopeless! You could take a t-booster, but at this age, we would suggest going back to the basicsPractice eating a balanced diet and get lots of regular exercise in. Plus, get a good night's sleep since this will help your body recover and aid in stress reduction.

Are Testosterone Booster Supplements Safe?

It's natural to be concerned about your safety. So before you take a test booster, you should see if it's safe first. The good news is that every testosterone booster on this list is safe for consumption! Unlike anabolic steroids, which can result in very severe side effects, these supplements won't hurt you in the long run.


The best T-booster in this list is TestoPrime, but Testo-Max and TestoFierce are great too!

TestoPrime stands at the top because they have the most research to back up their supplement's effectiveness, plus they have a complete refund guarantee, no questions asked!

Testo-Max is a great booster with a fair money-back guarantee, but it needs to be stacked with other Crazy Bulk boosters if you truly want to bulk up.

TestoFierce is safe and legal with proven ingredients, but the recommended dosage might turn off some users.
