The 7 Best Testosterone Boosters for Muscle Gains 2021

(Last Updated On: May 7, 2021)

If you are looking to build muscle, then having more testosterone would be a good place to start. More testosterone generally means you have more muscle and an easier time building it.

Think about it, the biggest and strongest kid in 7th grade was the kid who had gone through puberty before everyone else and had way more testosterone than the other kids. It’s also why men are bigger and stronger than women. And how do you think those female bodybuilders get big muscles anyway? They take testosterone that’s how.

The truth is:

Having more testosterone makes it much easier to build muscle.

That’s where the best testosterone boosters for building muscle come in, these natural supplements are more popular and more effective than ever and will make muscle building much easier and faster for you than it normally would be.

Let’s take a look at the facts you should know about natural testosterone boosters as well as the best ones for muscle gains.

Going with Natural Testosterone Boosters vs Synthetic

When it comes to boosting your testosterone, you can either go the natural route or go synthetic. The synthetic route means going to the doctor and getting shots on a regular basis. It also means your natural testosterone production will likely shut down and you will be stuck taking shots the rest of your life or have next to no testosterone in your body. Synthetic testosterone should definitely be a last resort.

On the other hand…

Natural testosterone boosters, on the other hand, are made from select herbs, vitamins and minerals that have been scientifically shown to work with your body to increase your own natural production of testosterone. And the great part is if you stop taking a natural test booster your testosterone levels will simply go back to where they were before you started taking them. This makes the natural route much safer and preferred.


Best Testosterone Boosters for Muscle Gains

Now it’s time to look at the best testosterone boosters for building muscle gains.

#1 Testogen

best testosterone boosters for muscle building

Testogen is a unique supplement because it doesn’t rely on weird ingredients from far away that you’ve never heard of.

It’s a collection of vitamins, minerals, and herbs that have all been proven in scientific studies to naturally increase testosterone. If you want to know how to build muscle with all-natural supplements, this is your answer.

Let’s review the ingredients in Testogen and how they help to boost testosterone for muscle gains.

An amino acid regulator that supports hormone production, D-aspartic acid has been shown to enhance testosterone production. One study found there was an increase of over 45% in just a few weeks! [1]

One study showed that men taking magnesium supplements while engaging in a strength-training program for seven weeks had higher levels of testosterone as well as muscular strength and power output. [2]

When you aren’t getting enough vitamin B6 in your diet, you are at a higher risk for lower testosterone and higher estrogen levels. Vitamin B6 promotes androgens and metabolizes estrogen. It also increases levels of pyridoxine, which is needed to produce serum growth hormone. [3]

An important daily mineral, zinc has long been associated with healthy testosterone production. When it’s paired with magnesium and vitamin B6, the trio is called ZMA. There is a synergistic relationship and the benefits of ZMA include improved sports recovery and healthy testosterone levels. [4]

There is a direct correlation between low testosterone levels and low vitamin D levels. By supplementing with vitamin D3, you can keep t-levels healthy. The best vitamin d supplements are always paired with vitamin K1. Speaking of which… [5]

Testogen also contains vitamin K1, which helps your body absorb the vitamin D. By increasing the bioavailability of vitamin D, you might see even better results. [6]

Also called stinging nettle, this herbal ingredient blocks testosterone from binding with a protein called SHGB. The boost in testosterone in your bloodstream allows it to do more useful things like support muscle gains. [7]

A well-known aphrodisiac, Korean red ginseng is often used as a natural remedy for erectile dysfunction, but it’s also used to support healthy testosterone production.

A popular ingredient in men’s health supplements, fenugreek extract contains furostanolic saponins, which have been linked to higher testosterone production. [8]

Several studies have demonstrated that this trace mineral can promote healthy testosterone production while it lowers estrogen levels, making it an ideal muscle building ingredient. [9]

Finally, we have piperine. Derived from black pepper, piperine by itself doesn’t increase testosterone. However, when included in a test booster like Testogen, it has been shown to significantly increase the bioavailability of all the other ingredients.

This means that your body can absorb and utilize the ingredients more efficiently. Better bioavailability could mean better results.


Testogen before and afterPros

  • Many birds with one stone: Increases testosterone, promotes muscle growth, and boosts libido

  • One month can be pricey. It’s more cost-effective to buy a few months at once.

 #2 Centrapeak


Centrapeak is a newer product to the market and if you are looking to build muscle then this bad boy will definitely deliver.

This product works to increase testosterone production in 3 ways. First, they use Leydig cell stimulation to stimulate your testosterone-producing cells to help maintain peak test production. Second, Centapeak reduces the amount of globulin in your blood which your testosterone is bound to, this leaves you more of the desired free testosterone coursing through your veins. Lastly, Centrapeak uses natural aromatase inhibitors block the conversion of testosterone to estrogen, it also helps to directly reduce estrogen activity in the body.

This product is a bit different from testosterone boosters out there in that it is also a nootropic designed to increase your mental energy, focus and give you a positive mental state. It does this by using ingredients that support serotonin, dopamine and GABA production.

Centrapeak is premium priced but they do offer free shipping on all order and you can also save when you buy in bulk. Buy 2 boxes and you save $13 and if you buy 3 boxes you get 1 free.

#4 Testofuel

Best Testosterone Booster

Testofuel is one of the premier muscle-building testosterone boosters out there right now. It has been out for a few years now and many competitors are is still trying to catch up with it.

One of the reasons Testofuel is such a good muscle builder is because it contains a massive dose of D Aspartic Acid which is great for raising testosterone levels and also increasing muscle size.

Testofuel also boasts a nice dose of oyster extract as well making it a very potent testosterone booster. On top of that it has generous doses of zinc, magnesium, fenugreek, and vitamin D. The nice part is there aren’t any filler ingredients or proprietary blends to watch out for. Everything is straightforward and the ingredients are top-notch.

Another nice thing about Testofuel is that it will give you a boost in sexual function and libido as well. It is made to build muscle and increase testosterone, but when you increase testosterone levels you will feel in the bedroom as well make no mistake.

This one also offers a money-back guarantee so there really is no risk, if it doesn’t work for you then you get your money back. None of the others on the list will do that. It also has excellent reviews. Put all that together and you can see why it is in our top spot.

TestoFuel costs $65 per bottle – which isn’t cheap by any means. That said, it still costs less than some of the newer testosterone boosters on the market.

#5 Super Test by Beast Sports Nutrition

Super Test Review

Coming in third place we have Super Test from Beast Sports Nutrition. This one another one to consider for a good muscle builder.

One major difference with this one compared to the others is that this one is actually available in both capsule and powder form. This is great for people who don’t like to swallow the capsules, some of which can be pretty large when it comes to supplements. There is a downside with the powder form though in that the flavor has some pretty bad reviews, many people said it tasted like battery acid. All test boosters that come in powder form have bad reviews on the flavor though so this is nothing new. Some people have had luck mixing it with Gatorade so give that try and see if you have any luck. If not you may have to choke down the capsules.

Looking at the ingredients this one has four complexes in it for testosterone boosting, estrogen control, DHT control, and a liver and kidney detoxification complex. In these complexes, they have some good ingredients like Ashwagandha Extract, Tongkat Ali, Fenugreek and Puncture Vine. The problem is they are all in a proprietary blend so we have no idea what kind of dosing they use on these ingredients.

Overall the reviews on this one are mixed but most of the negative reviews are about the flavor and not the effectiveness. Price is another thing to watch out for on this one as it is the most expensive on the list. It is the best of all the testosterone boosters that come in powder form though so that is why it is in third place.


  • Best testosterone booster on the market in powder form
  • Boosts testosterone and lowers estrogen


  • Proprietary blends make it impossible to know the doses of ingredients
  • Negative reviews on the taste of the powder form
  • Most expensive on the list

#6 Hypertest XTR by Axis Labs

Best testosterone boosters for muscle gain

Coming in fourth place on our list of top testosterone boosters for muscle gains we have Hypertest XTR from Axis Labs. This one is another pretty good one with some really solid ingredients.

Hypertest is made to be both a muscle builder as well as a libido enhancer so if you are having trouble in the libido department this one could help while also being an effective muscle builder.

Looking at the ingredients Hypertest XTR uses a nice dose of D aspartic acid along with zinc, magnesium, and vitamin B6. They also use a big dose of Ashwagandha Root to help keep the cortisol levels down which is really nice. All are good ingredients and we like that it has the shortest list of ingredients on our list. They picked what was effective and left the rest out.

We also like that it isn’t a proprietary blend and that everything is simple and straightforward. They use some pretty solid ingredients and the reviews are mostly favorable.


  • Solid ingredients
  • No proprietary blend
  • Simple formula


  • Some reviews are unfavorable
  • Only one dose per day allowing test levels to drop between doses

#7 Test Freak by Pharmafreak

Testosterone booster test freak

Rounding out our list we have Test Freak by Pharmafreak. This one is a good muscle builder and it helps with libido as well. In fact, it is also on our list of the best testosterone supplements for vitality. This one does both of these things pretty well and is one of the best testosterone products on the market obviously.

Test Freak has 3 complexes in it, they have one for testosterone boosting, one for estrogen control as well as one for DHT support. As for the ingredients, they use 2 forms of Fenugreek, Tribulus Terrestris, saw palmetto, zinc, and magnesium. This one also uses a proprietary blend in each of the three complexes so again we can’t be sure on the doses of most of the ingredients.

Test Freak can also be stacked with their other test booster Anabolic Freak. Anabolic Freak does have a large dose of D Aspartic Acid in it among other ingredients so it could be worth your while to use them together to get the most muscle building. It can be a bit of a pain to use them both and on the expensive side but both of them together should do well at building muscle.


  • Works for both muscle building and libido
  • Uses a complex for testosterone boosting, estrogen control and DHT support
  • Can be stacked with Anabolic Freak for an amplified effect


  • Uses proprietary blends
  • Can be expensive when stacked with Anabolic Freak

Best Testosterone Booster Ingredients for Muscle Gains

When it comes to natural testosterone boosters that build the most muscle these are the ingredients to look for:


D Aspartic AcidD-Aspartic Acid

This is a big ingredient to look for if you are looking to build muscle. This is because it has been shown to not only increase your testosterone and lower estrogen which will help build muscle in itself, but it has also has been shown to pack more protein into your muscles leading to more muscle growth.

Other studies have also shown D-Aspartic Acid to increase growth hormone in animals. This is definitely an ingredient to look for when it comes to muscle building.


Oyster ExtractOysters and testosterone

This is another really good ingredient that is actually pretty uncommon in testosterone boosters. As you may know, oysters are known to be a natural aphrodisiac. This is because they are loaded with testosterone boosting ingredients. Oysters are full of zinc which is the most important mineral when it comes to testosterone boosting.

They also have a large dose of magnesium in them and magnesium is another mineral that has been shown to boost testosterone levels. This is why the extract from oysters is such a great ingredient. Plus, eating oysters all the time would get old and expensive.


Zinczinc pills testosterone

As we just mentioned with the oyster extract, zinc is an important mineral when it comes to boosting testosterone. Studies have shown that increased zinc consumption leads to increased levels of testosterone. Studies have also shown that if you restrict zinc consumption then testosterone levels go down.

If you want your test levels up, then zinc is a big part of that. This is why most testosterone boosting supplements out there have a dose of zinc in them and usually a large one.


MagnesiumMagnesium ingredient

Now we move on to magnesium which is another important mineral for muscle gains. Magnesium has been shown to help with muscle fatigue, cramping, and soreness. This can lead to better workouts and more muscle gains.

Magnesium is also needed to metabolize proteins as well and as you probably know proteins are the building blocks of muscle. It has also even been found that men with more magnesium in their blood have higher testosterone levels as well.



Ginseng is a plant herb that is used for many things in the human body and boosting testosterone is one of them. Ginseng has been shown to increase sex hormones as well as boost testosterone levels. It is also a bit of an aphrodisiac which is a nice bonus.


Vitamin Dincrease testosterone

Vitamin D is something people get naturally from the sun. The problem is many of us don’t get enough and people lack vitamin D because of it.

Studies have shown that people with low vitamin D levels have significantly lower levels of free testosterone so it is important to be sure you are getting enough.


Ashwagandha ExtractAshwagandha ingredient

Ashwagandha Extract is a root powder that can lower cortisol levels in the body. This is important because cortisol can wreak havoc with your testosterone levels so keeping cortisol levels down can be a big help.

This ingredient works by reducing the effects of stress on the body, therefore the body produces less cortisol.


Tongkat AliTongkat Ali ingredient

This one is a Malaysian herb that has been used for many years to both raise testosterone levels and also lower estrogen levels, a very manly herb indeed.


What Low Testosterone Looks Like?

If your testosterone levels are low, you won’t feel the same as you likely did in your younger years. Some symptoms of lower testosterone levels include:

  • Lowered muscle mass
  • Decreased strength
  • Increased fatigue
  • Increased body fat
  • Low bone density
  • Lowered sex drive
  • Lowered sexual function

This is not a fun way to live and your testosterone levels will continue to drop as time goes on. Luckily a good testosterone booster can reverse these symptoms and raise your testosterone levels back to where they once were and sometimes even higher.

Watch for Proprietary Blends

Proprietary blends have become a bit of a problem in the supplement industry. What the supplement companies do is take a bunch of ingredients and mix them together in what is called a “blend”.

The problem is…

They only tell you how big the blend is and not how much of each ingredient is in there so you have no way of knowing. Many testosterone boosters and other supplements out there are proprietary blends, there will even be some on this list, unfortunately.

There are so many of them out there it is just unavoidable. When possible you should choose the supplement without the proprietary blend though so you know what you are getting.
