When you hear of testosterone boosters, you probably think of a bedroom issue, such as erectile dysfunction or low sex drive.

While testosterone boosters do address that, they are most often taken to help ramp up physical performance.

Testosterone levels naturally drop as we age, so we bid bye to our distinctly male physiology (i.e. bigger muscle muscle and stronger bones) and might need to supplement in order to maintain our physique.

After a month of research with 30 products studied, the Total Shape team came up with a list of testosterone supplement recommendations that will boost your male hormones to give your the most out of your workout routine.

Our Top Testosterone Boosters (2021)

1 - TestoFuel (Editor's Choice)

Testofuel thumb

TestoFuel has built a solid reputation and is a well-known testosterone booster amongst bodybuilders because of its ability to help produce larger, more well-defined muscles.

TestoFuel testosterone booster relies on three primary ingredients to improve muscle mass and strength. These ingredients are D-aspartic acid, oyster extract, and vitamin D.

D-aspartic acid is an amino acid that plays a key role in the biosynthesis of proteins, which are the building blocks of muscle mass tissue.

The rest of the ingredients, like Vitamin D and zinc (the key element in oyster extract), are also known for their role in promoting the production of healthy muscle tissue.

  • Rich in ingredients such as D-aspartic acid, vitamin D and zinc
  • Helps stimulate the formulation of HGH
  • Also contains the anti-inflammatory fenugreek
  • Satisfaction guaranteed or your money back.
  • Not the cheapest testosterone supplement

Combined as a formula, these three also stimulate the production of growth hormone which helps kickstart your efforts to pack on the bulk.

It is, however, not the cheapest among the best testosterone booster supplements. But if you want award-winning muscles but don't want the side effects of steroids, TestoFuel booster may be a right find for those who experience low testosterone levels.

2 - Testogen


This is another testosterone booster product that I have noticed a lot at the gym. And having talked to several men int he gym who have been taking it for several months now, I can tell from their appearance that something is working.

The ingredients aim to naturally boost testosterone levels, and is also packed with vitamins like D3.

This simple little extra helps release more testosterone into the bloodstream. It reduces the amount of testosterone being converted into estrogen, which is a completely natural process to maintain a healthy testosterone level.

  • Naturally increases strength and stamina, and energy
  • Helps to reduce inflammation in muscles and joints after workouts
  • Indirectly triggers growth hormone release for faster bulking
  • 60-day money back guarantee shows how confident they are in the results
  • A Little bit more vitamin D3 would be great

The only thing I would say is that they could have improved the amount of D3, as bodybuilders usually require a higher dose.

3 - Prime Male

This is one of the natural testosterone boosters in the market, and the brand has developed a large and loyal following over the years for one simple reason:

It works.

Like TestoFuel, this testosterone booster relies heavily on ingredients like D-aspartic acid to drive muscle growth. D-aspartic works by helping boost testosterone levels over the short term.

What you do with that elevated testosterone level is up to you. Most put it to work in the gym where they carve out a new, massive, and more well-defined physique.

  • A full range of natural muscle building ingredients
  • Helps promote muscle growth and tissue strength
  • Includes D-aspartic acid and luteolin as its essential ingredients
  • Facilitates improved blood flow
  • Online sales only

The Prime Male testosterone booster also utilizes Korean red ginseng, which helps to facilitate the increased blood flow muscles require, as well as bioperine and luteolin, which is a powerful antioxidant and helps delay apoptosis (cell death).

All in all, this brand is a reliable testosterone booster that will help you achieve that body that you want.

4 - CrazyBulk Testo-Max

Another recommendation on our best testosterone booster list is Testo-Max from CrazyBulk.

CrazyBulk has become known for top quality health supplements, and Testo-Max is no exception.

This particular testosterone booster uses natural ingredients to help your body naturally increase testosterone levels for higher energy levels, improved sexual performance, and increased muscle mass and strength.

The main active ingredient is the amino acid D-aspartic acid which triggers an increase of luteinizing hormone. This hormone directly impacts how much testosterone your body releases.

  • Legal testosterone boosting ingredients
  • Natural ingredients makes it safe to take product
  • Helps to increase lean muscle gain
  • Also works as an active fat cutting agent
  • Requires taking 4 capsules per day

However, if you don’t have all the minerals needed for the testosterone production, then it won’t do much no matter how much luteinizing hormone you make.

Fortunately, Testo-Max provides zinc and vitamin B6 which are vital for those who have low testosterone to see some serious muscle gains.

5 - Prime Labs Prime Test

This testosterone booster testosterone booster is an all-natural supplement that includes boron.

Boron, when added to the formula, is known to help facilitate the growth and maintenance of a strong skeletal system and to bolster muscle integrity.

Other ingredients include wild yam extract, orchic substance, nettle extract, Tongkat Ali extract and saw palmetto extract.

All of these ingredients see to it that they work together to boost short-term testosterone enhancement and increase energy levels so you can enjoy a more productive workout.

These testosterone boosters also increase the body's stamina and energy and help improve circulation, which is essential in aiding new and larger muscles to work properly.

  • Claims to be safe and has all-natural ingredients
  • Helps improve circulation and increases stamina
  • Provides a temporary testosterone enhancement
  • No known adverse side effects
  • Ingredient levels hidden behind “proprietary blend” designation

Most of the users of this testosterone booster brand also claim that the supplement aids to boost their libido and sex drive as well.

Prime Test is only available online, but unlike some other supplements, it can be found at quite a number of reputable websites.

6 - Sheer Alpha

Sheer ALPHA thumb

Sheer Alpha testosterone booster makes a lot of claims about improving your sleep, reducing your stress levels, raising your IQ score and more (just kidding about the IQ scores).

Some of those claims are questionable at best but what cannot be denied is that Sheer Alpha will provide a short to moderate-term boost in your production of testosterone levels, which can then be leveraged to help generate massive, more powerful muscles.

As we age, we naturally begin producing less testosterone, which can lower physical performance and sex drive, and Sheer Alpha is designed to offset that tendency.

To do the job, it employs a combination of natural ingredients, such as horny goat weed extract, maca root powder and ginkgo biloba, along with various other ingredients that stimulate the production of testosterone in the gonads and adrenal gland.

  • All natural ingredients
  • Helps stimulate the production of testosterone
  • Enhances physical performance
  • May also help improve sex drive
  • Can cause upset stomach or loss of appetite in some users
  • Some claims not related to physical performance are suspect

The result is more of this vital hormone available as you enter the weight room for your workout.

7 - Nugenix Test Booster

Nugenix thumb

Nugenix is a relative newcomer to the testosterone booster landscape, but it has quickly gained a reputation from people who used to have low testosterone levels for being both effective and safe.

While we found it to be one of the best testosterone booster supplements on the market, the fact that it masks ingredient proportions behind the veil of a proprietary blend means we can't put it at the top of our list.

The fact is, this type of physiological manipulation is no joke, and therefore transparency is important.

That said, there's no doubt that its blend of Testofen, L-Citrulline Malate, and Tribulus Terrestris produce a noticeable performance boost in the gym and that it's supporting cast of vitamins and zinc are well-considered.

  • A reliable ingredient list, including tribulus terrestris, testofen, and L-citrulline malate
  • Vitamins B6 and B12 to bolster muscle integrity
  • No known side effects when used as directed
  • Proprietary blends undermine transparency
  • Among the most expensive testosterone supplements

As such, if knowing exactly how much of what is in your muscle building supplement isn't all that important to you, then you will likely find plenty to like in Nugenix - except for the price.


1. What are Testosterone Boosters?

pills for boosting testosterone

Contrary to popular belief, testosterone boosters don’t provide a load of testosterone in pill form. They don't work that way.

Studies show that synthetic testosterone supplements may do that, but the effectiveness and safety of such products is a cause for great concern.

Such straightforward shots of testosterone present a very real likelihood of nasty side effects both short and long-term, including the possibility that they may inadvertently shut down the body’s natural testosterone production.

In contrast, natural testosterone supplements help stimulate the physiological mechanisms your body uses to produce testosterone on its own which then causes its levels to rise.

Other top testosterone boosters we've ranked:

It's a far safer and, most believe, more effective method for obtaining the additional male hormone you need to maintain robust health as you age and to power your muscle building efforts.

There are several methods for boosting testosterone production and the supplements profiled above all take slightly different paths to achieve the same results.

2. Do Testosterone Boosters Work?

Yes. At least the t boosters we have chosen for our list. As with any supplement though, you need to be careful which ones you choose since supplement production is not supervised or regulated by the FDA.

There are several methods for stimulating testosterone production that are backed up by scientific research and the best testosterone boosters utilize them to achieve positive results.

Some testosterone booster products use the amino acid D-aspartic, while others utilize what is known as horny goat weed extract and other natural ingredients.

But, they all have the effect of stimulating testosterone production in the gonads and adrenal gland, which in turn bolsters your ability to push through physical barriers that used to limit your performance in the gym. (1)

Here's a video from Shredded By Science explaining if these testosterone booster supplements work.


3. What Are the Potential Side Effects?

Unlike synthetic testosterone boosters or pills that can wreak havoc on your system and produce everything from headaches to confusion to a shutdown of your adrenal gland, these boosters are typically safe and effective when used as directed.

At most, you may experience a slight upset stomach or loss of appetite, but that usually only occurs when a person has a naturally sensitive digestive system.

The fact is that most men who use these will not experience any adverse side effects from using testosterone boosters, as long as they confine their consumption to the recommended dosages.

Like other supplements and medication, testosterone therapy comes with risks and possible side effects. This is particularly true if you try to take it for normal aging rather than for treatment of a condition.

4. What foods are best for boosting testosterone?

If you're in search for some foods that can increase testosterone levels naturally, you might want to include the following in your diet -- ginger, leafy greens, olive oil, and oysters.

While supplements are a great way to give you that extra boost, it’s always best to try and get as many supporting nutrients as possible through the food you eat.

Let’s take a closer look at the suggestions.

  • Ginger: There is a very good reason that ginger has been used for madical purposes throughout the world for thousands of years since it's generally good for your health. Most people just look at it from the point of view of immune system benefits. But a recent study from 2016 [1], found some direct links between ginger and testosterone levels. Simply add some to your meals or boil it up in hot water and drink it as a tea.
  • Leafy Greens: Vegetables like spinach and kale have high levels of zinc and magnesium. Magnesium is a mineral that is required in the production of testosterone. This is supported by the results of a 2011 study [2] which showed a significant increase with athletes in particular.
  • Olive Oil: Many people use olive oil as one of the healthiest alternatives to other plant-based oils. While it has benefits to heart health and is believed to prevent certain cancers, there is also a link to fertility and testosterone levels boost production in men.
  • Oysters: Oysters are one of the most zinc-rich foods available and have long been eaten by cultures around the world for its aphrodisiac properties. With zinc being a vital nutrient for the production of testosterone, oysters are a simple seafood that will help give you a boost. This increase in testosterone levels help in improving physical performance and increasing energy levels and sex drive, thus preventing the occurrence of erectile dysfunction.

What to Look in for in Testosterone Boosters

For most older men, low testosterone levels can get in the way of your quality of life day after day. It affects your capability to do things and weakens your sexual drive by experiencing erectile dysfunction more often.

I understand that choosing the best testosterone booster for men can also get confusing at times, so here are things you have to look into to help you choose a good product.

  1. Formula. Before you go gulping the first t booster you get your hands on, make sure that the product has the necessary formula for your needs. Considering the correct formula will not only help you achieve your goals; it will also ensure that what you're putting into your body is safe.
  2. Ingredients. Testosterone boosters come in various forms and may contain ingredients that are natural or synthetic. The t boosters presented in this article use natural ingredients, as most users and coaches prefer to go the all-natural route. The herbal ingredients have very little to no side effects while providing the desired testosterone boost.
  3. Dosage. You can't just go buy and use a product and not consider the recommended dosage. The best way to go about this is to always consult a physician, especially if you have specific goals in taking a t booster. Your doctor may request you to undergo tests and have the results reviewed regularly to make sure you're getting the desired results without overdosing.
  4. Effectiveness. The effectiveness of a product may not be absolute, but it's best that you do your research and read user reviews before starting a t booster supplement. Ask your doctor about some recommended products, and take time to read on studies about the brand and the ingredients they use.

Among the several highly effective testosterone boosters on the market today, TestoFuel is considered one of the top products due to its reliable formulation and benefits.

The quality of its production and the fact that it includes the anti-inflammatory fenugreek is what makes it a favorite in the gym, especially if you’re looking at bulking up.

If you are looking for the best way to ramp up your workout efforts without endangering your health or having to live with odious side effects, then you should consider choosing TestoFuel test booster.
