5 Best Supplements To Increase Testosterone | Detailed Comparison

After putting the top five testosterone boosters on the market to the ultimate test—the outright winner is undoubtedly Testogen.

This potent product, packed with 11 scientifically proven T-boosting ingredients, is the most effective and natural way to safely restore your vitality, enhance libido, boost muscle mass, and drop the unwanted pounds.

ArticleThis article explains the power behind the supplement, why it’s the best testosterone booster and the reasons you should use it as part of your male wellbeing regime.

The Low Testosterone Problem

Since your teenage years, your testosterone has been on a downward curve. As this is a natural process associated with aging—the statistics show that it’s incredibly common.

The scary facts are:

  • Between four to five million men suffer from low testosterone in the United States.1
  • Your testosterone levels drop at the rate of one percent per year after the age of 30.2
  • Around 43 percent of men over the age of 65 suffer from low testosterone levels.3
  • Declining T-levels are accelerating—in 1987, men possessed 17 percent more testosterone compared to those of a similar age today.4

While the numbers alone are alarming—they don’t fully explain the enormous impact that low testosterone levels can have on the individual.

Man presenting in front of peopleLet me share with you my personal experience—and how using the best testosterone boosters turned my life around.

My Story

I’ve always led a reasonably active lifestyle—trying to ensure that I exercised frequently and ate a healthy diet.

Man holding a dumbbell

However, once I entered my mid-30s—my body seemed to be operating in a lower gear. I just felt like I’d lost the vitality that had been present throughout my life. Work, sports, and daily tasks were becoming physically more challenging—and my lust for life kind of waned.

Although I found it annoying—I just put it down to becoming older—and something I had to accept.

But then, things took a turn for the worse.

Irritated faceI was beginning to lose interest in being intimate with my partner. Sex three times a week used to be the standard—but now I found it a chore more than a pleasure.

Eventually, sex once a month was the most I could muster. Even my partner stimulating me had little effect on my sex-drive. She began to believe that I no longer found her attractive—to the point where I found her crying in despair alone in the bedroom.

This broke my heart—I knew I had to find a solution.

I’d heard about testosterone boosters—and how they could help to raise libido—but I was skeptical. However, I decided to take the plunge. I sought out the top testosterone boosters on the market and decided to give them a try.

The results were incredible.Two hand holding a box

Through a five months of trial and error experimenting with these supplements—all of which slightly varied in their formulation—I found that Testogen was the most powerful of all.

After a few weeks of use, my energy levels had risen, my libido was higher than it had been in years—and my partner was reaping the rewards in the bedroom too.


I was a convert.

Let me show you why I consider Testogen to be the best testosterone booster currently available.

Overview of The Testosterone Boosters

Before we get into the serious detail behind Testogen, the best testosterone booster, here’s a quick overview of the five supplements I tested.

5 Best testosterone boosters

Why Testosterone Booster Work?

Male signLet me make something clear.

Even the best testosterone booster on the market doesn’t contain any of the male hormone itself.

That’s the domain of steroids and TRT (testosterone replacement therapy)—which rely on delivering exogenous testosterone directly into the body—usually through the use of hypodermic needles.

While effective, they can induce side effects, including:

  • Increased risk of prostate cancer.5
  • Insomnia and interrupted sleep.
  • Problems with the urinary tract.
  • Elevated red blood cell production.
  • Inhibition of natural testosterone creation.

However, testosterone boosters work in a much more body-friendly way.

PillThese supplements are usually supplied in pill form. When taken daily, they work in conjunction with your physiology to raise T-levels.

How Do Testosterone Boosters Work?

The best testosterone booster will contain ingredients which science shows can:

  • Encourage the testes to produce more testosterone.
  • “Freeing” testosterone which has been tied to SHBG (sex hormone-binding globulin) rendering it unusable.
  • Inhibiting the effects of the female hormone estrogen—which can otherwise restrict the power of testosterone.

As these supplements contain no synthetic steroids or hormones—they’re virtually side effect free. The ingredients are natural and will not impinge negatively on your physiology.

Is a Testosterone Booster Right for Me?

PharmacistAs natural supplements, testosterone boosters can be purchased over the counter and used by any male over the age of 18.

The best testosterone booster is the optimum route to elevate low T-levels. If you’re suffering from any of the following symptoms, your testosterone production may be restricted, and therefore benefit from supplementation:

  • Lack of sexual interest and desire.6
  • Problems attaining and/or sustaining an erection.7
  • Reduction in the size of the testes (testicular atrophy).8
  • Diminished semen production.9
  • Tiredness and lethargy.10
  • Lowered sensation during orgasm.
  • Inhibited motivation.
  • Anemia.
  • Hot flushes.
  • Loss of self-confidence.
  • Reduced muscle mass.11
  • Increased likelihood of bone breaks and fractures.12
  • Loss of body hair.13
  • Elevated accumulation of body fat—especially around the abdomen.14
  • Depression and lowered mood.15

BoyHowever, it’s not just older men with impaired T-production that can benefit from the best testosterone booster.

Studies show that elevating T-levels are ideal for athletes and bodybuilders—increasing strength, muscle growth, and stamina.16

Why Am I Experiencing Low Testosterone Levels?

The combination of physiological, genetic, and environmental factors can contribute to low testosterone levels.

The most common reason is our age.

ManDuring puberty—your testosterone levels reached the highest level they will ever attain during your life. This massive surge in the male hormone powered your change from boyhood into manhood—driving muscle, penis, and testicular growth, encouraging body and facial hair, and lowering your voice.17

Then the decline begins.

Although the decrease in testosterone is initially gradual, you experience a rapid reduction around 50 years of age—being around 50 percent of previous levels.18

ScientistScientists suggest that this decline (known as late-onset hypogonadism or male andropause) is due to the reduction of Leydig cells in the testes. These are the powerhouses that facilitate T-production, which replenish themselves less rapidly as every year passes.19

Using the best testosterone booster can help to reverse this aging decline—restoring your T-count to that of a much younger guy.

However, while advancing years are the most common cause of low T-levels, there are other factors which can have an impact, including:

  • Genetics—the inherited genes from your parents influence how much testosterone your testes produce.20
  • Poor diet.
  • Over-exercising—extensive endurance sports can interfere with the HPTA (hypothalamus-pituitary-testes axis)—the signal from the brain to the testes to produce testosterone.21
  • Obesity—experts have shown that those who are overweight exhibit lower testosterone production than men of a “normal” weight.22
  • Sleeping person in bedPoor sleep—testosterone is highest during REM (rapid eye movement) slumber.23
  • Abuse of steroids—synthetic hormones can inhibit the production of testosterone.24
  • Excessive alcohol consumption.25

How to Increase Testosterone Levels?

In scientific terms, doctors diagnose low testosterone when it drops below 280 to 300 ng/dl (nanograms per deciliter). To give you some idea of context, your T-count during puberty reaches 896 ng/dl reducing to around 400 ng/dl at the age of 40. 26 27

If testosterone levels do drop to the clinically defined low level—your physician may recommend TRT.

PrescriptionHowever, doctors only usually prescribe TRT in severe cases of hypogonadism. There are less invasive methods of elevating T-levels that are budget-friendly and only require small adjustments to your lifestyle.

These include:

A Healthy Diet

Studies show that nutritional intake plays a significant role in testosterone production. The poorer the diet—the lower your T-count.28

Healthy diet can increase testosterone

Avoiding excessive fat consumption—and ensuring you receive adequate amounts of zinc, magnesium, and vitamin D can help to maintain healthy androgen creation.29

Powerful T-boosting foods include:

  • Oysters.
  • Lean red meat.
  • SpinachPomegranates.
  • Spinach.
  • Sunflower seeds.
  • Broccoli.

Use Vitamin Supplementation

Sometimes your personal food preferences or intolerances can make the intake of the critical testosterone-enhancing vitamins and minerals tough.

Supplementing with multivitamins, especially those high in iron, zinc, magnesium, and vitamin D can help to ensure you ingest adequate quantities.

Exercise Regularly

As mentioned earlier in this Best Testosterone Booster article—excessive endurance exercise can lower testosterone production.

WeightlifterHowever, providing you don’t take it to the extreme—a regular workout is beneficial for elevating your T-count.

Studies show exercise, especially resistance training (weightlifting) heightens testosterone levels.30

Quit Smoking

In addition to causing cancer—smoking can rapidly interfere with testosterone production.

Research shows that using cigarettes reduces the potency of testosterone—inhibiting its ability to promote healthy hormones in the male body.31

Sleep Soundly

As already explained in this Best Testosterone Booster article—REM sleep promotes testosterone production.

Sleeping person with pillowThe more you sleep, the more of the vital androgen you will create.

You can improve the quality and duration of your slumber by avoiding stimulants such as caffeine before bedtime, partaking in sexual intercourse, and taking a warm bath before retiring.

Cut Back on Alcohol

Excessive alcohol consumption will lower T-levels—so don’t go crazy.

However, it’s not all bad news.

Research shows that enjoying an adult beverage a few times per week can actually increase your testosterone count.32

Use a Testosterone Booster

CapsuleThe best testosterone booster will contain the most powerful and scientifically proven natural ingredients to elevate T-levels.

They’re probably the most effective tools to raise your testosterone count without the use of needles or exogenous testosterone.

Natural Supplements To Increase Testosterone

You don’t need to take synthetic steroids to raise your testosterone levels. Nature has provided some severely potent enhancers that are completely side effect free.

Below are the most effective and scientifically proven T-raising compounds that should be included in the Best Testosterone Booster.

Tribulus Terrestris

Floral designA flowering plant which scientists have shown can heighten sex drive and increase testosterone production.42

Some experts also believe that Tribulus can inhibit the action of SHBG—ensuring that existent testosterone isn’t “imprisoned” and rendered unusable.


This Meditteranean herb, like Tribulus, restricts the binding ability of SHBG.43

Fenugreek seeds and leaves on the table


A potent aphrodisiac, which scientists have discovered heightens free testosterone, impairs the function of estrogen, and can raise fertility.44


MineralsOne of the most effective T-boosting compounds known, although experts didn’t discover this ability until 2011.45


The compound which provides oysters with their aphrodisiac power. Zinc encourages the testes to produce more testosterone.46 Oysters are high in zinc.

Oysters, ice and lemon on a plate


Experts have illustrated that this mineral elevates testosterone creation—and is even more potent when combined with exercise.47

D-Aspartic Acid

An amino acid, which under clinical conditions, elevates T-count.48

B Vitamins

Vitamins bottleFrom the eight B vitamins, the two that are most beneficial for testosterone are B6 and B12.

While directly, they don’t heighten T-production—they provide the perfect conditions for creation, enhance testosterone’s potency, and may raise semen fertility.49 50

Nettle Leaf Extract

Researchers have illustrated the nettle leaf binds to SHBG—preventing it from imprisoning free testosterone.51

How Does It Feel?

After just three to four days of using Testogen, I was feeling more energized. It had almost become an effort to get out of bed in the mornings. But now, I was feeling alert and ready to tackle the day ahead.

As the weeks progressed—the benefits increased. My vitality carried through all aspects of my life—whether at work, home, or most importantly, in the bedroom.

RocketOverall, my self-confidence has skyrocketed. For the first time in years, I’m actually feeling good about myself again—a sense of manliness and attractiveness that had been lost.

How Fast Do I See Results?

One of the most astounding things I found using Testogen was that you don’t have to wait long to feel a massive difference.

Here are some details from my Testogen diary.

Week 1

Within just 3-4 days, I noticed that my energy levels were beginning to rise. I was feeling more enthused about going to work and hitting the gym.

Week 2

FireworksAfter two weeks of use—my libido was beginning to return—I was overwhelmed. It had been so long since I had actually instigated intercourse—but now I was actually taking the lead with my partner.

Week 3

By the third week—my energy was still rising. I believe partly to the improved sleep I was now enjoying every night. Whereas before I was waking every few hours, I was now in sound slumber for a continuous 7-8 hours.

Week 4

One Tuesday morning, I stepped out of the shower and viewed myself in the mirror. The love handles didn’t appear to be as prominent. I jumped on the scales to check, and it was true. I’d lost four pounds.

Week 5

Sun with glassesAfter five weeks, my desire for sex was as strong as I could remember. I think my partner may have even been getting a little annoyed by my rampant needs. What’s more, while before I didn’t exactly have issues in the erection department, I swear they were harder and allowing me to last longer.

The Future

All the benefits I received from taking Testogen, the best testosterone booster, were too good to be lost again.

Hence, since my first trial of this supplement—I haven’t stopped taking it.

I feel that Testogen has taken years off me—both mentally and physically.

When To Take My T-Booster?

Once you have selected your best testosterone booster, in my opinion – Testogen, it’s crucial that you take it consistently.

Using a testosterone booster every day ensures that your testosterone levels continue to build—if you miss a dose, this can lead to some of your hard work being undone.

Always read the manufacturer’s instructions before use—although usually, they provide directions to take the testosterone booster first thing in the morning.

CalendarThe longer you use the supplement—the more impressive the results. While your energy and libido may rise in the first few weeks—for fat loss, muscle gain, and insatiable sexual appetite improvements—I recommend you use the product for at least two to three months.
