What Makes You a Man

Just like any other man, you most probably aspire to gain muscles quicker, have incredible strength, build a strong body, and get rid of displeasing fat storages.

Also, you may strive for a high sex drive and a better sex life.

These goals are reachable with testosterone booster supplements.



#1 TestoGen: Best Natural Testosterone Support

TestoGen managed to become a leader in its realm due to the availability of the recently renewed formula which relies on the results of the latest clinical trials.

This formula represents the highly innovative approach to the creation of testosterone boosters. You can know for sure which ingredients and in which amount you take in order to:

  • Enhance testosterone synthesis in a natural way
  • Develop more muscle much quicker, spending for this purpose just months, but not years
  • Replace fat storages with strong, well-toned muscles
  • Increase strength substantially
  • Feel much more energized regardless of whether you are working out in the gym or trying to fulfill the daily tasks


#2 TestoMax

Testo-Max is a well-working supplement with a safe formula. This supplement is considered a worthy legal substitute to Sustanon which is a popular anabolic steroid.


It’s a perfect choice for the bodybuilders who strive to refuse from the use of anabolic steroids and, at the same time, find the product that will not be inferior to steroids.

Testo-Max offers you such an opportunity because it:

  • Enables substantial muscle growth
  • Maximizes strength
  • Increases stamina
  • Decreases recovery time between workout sessions
  • Boosts energy and power
  • Improves libido and bedroom performance
  • Is suitable for bulking and cutting cycles


#3 D-Bal

D-Bal is one of the top-class legal steroids invented by CrazyBulk in order the bodybuilders and other athletes could avoid the necessity to use real steroids.

This supplement was in fact created as a substitution option for Methandrostenolone which is more famous as Dianabol.

This is a natural testosterone supplement that ensures efficacy similar to Dianabol, but it is free from shortcomings peculiar to the mentioned real steroid.

The ingredient content of this testosterone booster has recently undergone very important changes.

It was substantially strengthened so that now the renewed formulation is more effective than the authentic version of D-Bal.

Due to these renovations, the supplement maximally supports anabolic state, promotes unbelievable muscle development, and upsurges strength.


Who Typically Has Testosterone Deficiency

It’s a widely known fact that low testosterone which also has the name of hypogonadism is a common issue for all men regardless of their social status and country of living.

According to the clinical trials, the severity of aging process has a direct impact on the degree of hypogonadism which in its turn makes men resort to the help of different testosterone boosters.
In fact, the clinical trial carried out in 2006 has indicated that 39% of the male study subjects in their late 40s seriously lack testosterone. Just a tiny percentage of these men take any measures to improve the situation.

Another study has shown that 13 millions of American male population suffers from testosterone deficiency. And by the way, these men finally become the constant users of natural testosterone boosters.

Also, one more clinical trial found out that insufficient testosterone levels and aging process are really interrelated. In particular, 20% of male Americans who have already entered their 60s regularly face testosterone deficiency symptoms. In addition, 30% of American men who are in their 70s and 50% of American men in their 80s are testosterone deprived. Some of them want to combat this issue and take testosterone boosters of natural origin for this purpose.

Testosterone Deficiency Symptoms

The men often start thinking about the supplementation with testosterone boosters when they notice the symptoms related to the decline of testosterone levels.

  • Unpredicted Fat Formation. Sudden fat deposits which can’t be explained occur quickly. And it’s not an easy task to successfully cope with them, as well as with already existing fat storages.
  • Sluggishness. Low testosterone is fraught with the decrease in energy levels. This refers to both physical and mental tiredness which doesn’t let the men enjoy the life.
  • Weak Muscles. Muscle mass and strength always suffer when testosterone levels fall. What even worse is that conscientious exercising doesn’t assist in building muscle mass and boosting strength.
  • Muscle Atrophy. Insufficient testosterone levels are even able to provoke the development of muscle atrophy. This makes weight lifting and intense exercising impossible.
  • Osteopenia. Lack of testosterone may substantially increase bone fragility in men. It means that the likelihood of bone fractures grows considerably proportionally to your age increase.
  • Impaired Erectile Function. Poor testosterone production in the man’s body leads the lack of sex drive. The lower sexual interest the less erections you have. And your bedroom performance worsens.
  • Emotional Swings. Inadequate testosterone levels disturb emotional stability. As a result, you may frequently have bad mood, rapidly get nervous, irritate, fall into depression, and experience temper outbursts.
  • Increased Diabetes Probability. According to the clinical trials, type 2 diabetes may develop when testosterone levels drop with age. This happens because low testosterone contributes to insulin resistance.

It’s a proven fact that testosterone boosters of natural origin can effectively deal with the majority of these symptoms without the necessity to use artificial testosterone.

Testosterone in the Men’s Body

The man’s body uses testosterone for everything what allows a man to be a man. In particular, muscle strength and growth, sex drive, energy levels, body fat percentage, motivation, concentration, and many other masculine features depend on testosterone concentration in the men’s blood.

But when the man is getting older, the levels of this hormone start drastically falling. This becomes evident because of the negative changes in the body, such as poor libido, loss of strength, muscle size reduction, constant fatigue, detachment, etc.

And this is where testosterone boosters come into play. These products are usually of natural origin. And they are designed specifically for aligning the hormonal processes in the men’s body in a natural way. It’s a scientifically proven fact that the top-notch boosters really raise testosterone levels in men.

Let’s consider’ how exactly the boosters influence the male hormonal balance.


What Testosterone Booster Pills Are Intended for?

Testosterone boosting pills are created to:

  • Stimulate testosterone synthesis in a natural way
  • Accelerate muscle gain
  • Gain bigger muscle
  • Promote faster muscle recovery
  • Increase muscle strength
  • Decrease body fat, replacing fat storages with lean muscle mass
  • Rebuild self-esteem and lift mood
  • Boost motivation to work out more persistently
  • Restore high energy levels necessary for effective muscle building process

It should be noted that there are the men who have a great genetic potential to successfully build muscles almost without any efforts and regardless of their eating plan and exercise routine.

At the same time, there are the men who must sweat their guts out to see some positive changes. That is, they have to strictly follow the diet plan, consume much protein, and exercise a lot for a very long time.

Testosterone boosters are invented for the men who work without letup to get ideal muscles. These products will remove all obstacles, letting you easily reach your goals.

Why High Testosterone Is Important

The primary purpose for which the men, especially sportsmen take testosterone supplements is a desire to develop new bigger muscle mass.

If hormone levels are high, it’s a quite easy task to increase muscle size. And the achievement of this goal doesn’t take too much time. But if the hormone levels are low, the situation is the opposite. Thus, you will not have muscle gains and even will not be able to preserve the existing muscle mass.

The increased testosterone production is also crucial for the reduction of body fat storages. So, if you take care of maintaining sex hormone levels high, you will not only get rid of excessive fat, but also make your dream of a desired body composition a reality.

Sufficient testosterone concentration in the man’s blood is highly beneficial for libido. In this case, it’s possible to restore sex drive in men and hence revive sexual activity. As a result, sexual satisfaction will also grow.

There are also the additional benefits which each man with high testosterone levels gets. They include enhancement of mood, improvement of cognition, reduction of stress, and better sleep.

What Is the Mechanism of Testosterone Pills’ Actions?

The most effective supplements consist of the powerful mixtures of ingredients able to make the man’s body produce a higher amount of testosterone.

Their mechanism of action implies:

  • Normalization of Testosterone Synthesis

Brain and endocrine system play crucial role in testosterone synthesis. To urge them to perform this function properly, the man should take some important ingredients which are typically absent in the daily meal plan. The mission of testosterone boosting products is to make up the deficiency of these ingredients. In such a way, it’s possible to stimulate testosterone secretion.

  • Elevation of Free Testosterone Levels

According to the studies, sex hormone binding globulin binds to approximately 60% of testosterone available in the body.

Being bound, this sex hormone can’t give an anabolic effect anymore. It becomes almost useless for the man’s body. Testosterone boosters suppress globulin secretion. This makes free testosterone levels grow.

  • Estrogen Reduction

There is an enzyme called aromatase which has a strong impact on estrogen synthesis. And for this purpose, testosterone is used. That is, this sex hormone is turned into estrogen.

Testosterone supplements include the ingredients which can suppress the mentioned enzyme and, therefore, save testosterone. As a result, estrogen levels plummet, while testosterone levels raise.

Are Testosterone Booster Pills Truly Effective?

Many men still believe that the only sure way to boost own testosterone is to take pro-hormones or steroids. But this belief is far from reality.

If you also prefer steroids, natural testosterone pills are here to change your opinion. And though the power of these boosters doesn’t surpass the power of the synthetic drugs, their efficacy is enough to satisfy the men’s needs.

Recently, numerous studies have been conducted to confirm that natural ingredients truly can substantially promote testosterone synthesis. And the findings of these studies were positive. It’s remarkable that such ingredients don’t pose a threat to the men’s health.

Most Promising Testosterone Booster Ingredients

In fact, it’s also mistaken to think that each testosterone booster works well. There is a wide range of products manufactured with the use of completely outdated technologies. That’s why these products consist of the ingredients, the efficacy of which slims to none.

We have carried out own investigation to help you understand which now existing ingredients are the most promising ones.

This list of ingredients is backed with the results of different clinical trials. And if you are looking for the testosterone supplement, check whether it has at least some of these ingredients in its formula:

D-Aspartic Acid

This amino acid plays an important role in testosterone secretion. Acting in the brain, it’s responsible for the release of numerous hormones. Among these hormones, it’s possible to distinguish the luteinizing hormone, which regulates the testes’ functioning, and growth hormone, on which muscle development mainly depends.

According to some studies, d-aspartic acid helps eliminate rate-limits of testosterone production.

Also, the study was conducted to find out how 3-month d-aspartic acid supplementation influences on testosterone levels in male participants between 27 and 43 years old. The study has finally shown that testosterone levels in men grew by 30-60%.

The other studies have indicated that d-aspartic acid can enhance sex hormone synthesis in inactive men, as well as in men with testosterone deficiency.


Just a small number of supplements have this trace mineral in their formulas. And it’s really a glaring omission since boron has a great ability to stimulate testosterone production. It helps build muscle mass and make bones stronger.

The scientists found out that boron not only can elevate free testosterone levels, but also reduce estrogen synthesis. The intake of this trace mineral is able to facilitate and accelerate the achievement of your both sports and intimate goals.

The study has demonstrated that the male bodybuilders from the study group had much higher testosterone levels after the 7-week supplementation than the men from the placebo group.

Another study gave evidence that the 1-week intake of 10 mg of boron per day contributed to the free testosterone growth by 28%, estrogen reduction by 39%, and dihydrotestosterone growth by 10%.

One more study has indicated that the 2-month supplementation with 6 mg of boron per day caused testosterone growth by 29%.

Oyster Extract

Oysters are extremely rich in zinc which participates in the release of luteinizing hormones and promotes the increase in serum testosterone levels. The studies also have proven the importance of zinc for sex hormone secretion.

The 1-month study that involved 32 male road cyclists has shown that the supplementation with 20 mg of zinc daily led to the substantial elevation of free testosterone levels. During the study period, the men did high intensity exercises.

Another study in which 55 football players participated has also demonstrated that the 2 month supplementation with 30 mg of zinc daily considerably intensified testosterone production. Also, it led to the improvement of strength and power.

In addition, oyster extract contains a large number of the other crucial nutrients, including taurine, amino acids, omega 3, omega 6, and vitamins. Thus, this extract contains much vitamin D. People often take not enough vitamin D. But this vitamin is a great stimulator of testosterone production. It also enhances muscle strength and helps cope with the lack of sex drive.

Stinging Nettle

This plant is known for its ability to free up testosterone and give the body an opportunity to actively use it. This is possible due to the fact that the plant root contains valuable substances called lignans. These substances can bind to sex hormone binding globulin instead of testosterone. As a result, the levels of free testosterone elevate.

The plant can also inhibit aromatase and, hence, decrease estrogen levels. This leads to the increase in testosterone levels.

The mentioned effects of stringing nettle have been proven with in-vitro and animal studies. Also, according to the studies, the plant root extract supports prostate health.

Vitamin D3

It’s considered a vitamin, but in fact it acts like a hormone. It belongs to 24 nutrients without which the human body can’t survive. It’s necessary to get the bare skin exposed to sunlight to receive enough vitamin D3. However, people always lack this vitamin because they spend very little time outdoors nowadays.

This vitamin has an impact on the release of luteinizing hormones which in their turn contribute to the release of growth hormone, follicle stimulating hormones, and testosterone.

According to the studies, for the men with vitamin D deficiency, the likelihood of testosterone deficiency is very high, comparing to the men who have normal vitamin D levels.

The men without health problems who undergo the one-year supplementation with a small amount of vitamin D may experience the growth of testosterone levels by 25%.


This plant is gaining more and more popularity with its ability to indirectly promote testosterone secretion. The Asian Red Panax Ginseng features the greatest level of efficacy.

Ginseng is mainly known for its high potential to stimulate nitric oxide synthesis in men. This substantially strengthens circulatory system, helps enhance sports performance, and improves sexual potency.

It lowers glucose levels and, therefore, doesn’t allow insulin to negatively affect testosterone synthesis. In addition, the plant contains saponins which also raise testosterone levels and activate luteinizing hormone production.

The studies in male mice and rats have indicated that Panax Ginseng supplementation contributes to the elevation of testosterone levels.

The scientists also found out that this plant has an oxidative effect and, at the same time, suppresses cortisol production. This helps maintain testosterone levels normal.

The animal studies and some human studies gave evidence that Ginseng contributes to prolactin reduction. Prolactin is highly beneficial for the breastfeeding women but has a negative influence on testosterone secretion in men. So, by inhibiting prolactin synthesis, the plant normalizes testosterone levels.


This plant that grows in south Europe and Asia has sex drive increasing properties known from the ancient times.

It promotes better release of insulin. Due to this, bigger muscles develop faster. Male potency also improves. High antioxidative potential of Fenugreek maintains the men’s overall health.

There is scientific evidence that Fenugreek can support healthy testosterone production. The study that lasted for 1.5 months and involved 60 men without any health problems has proven this. The study implied the intake of 600 mg of plant extract daily. The supplementation led to the normalization of testosterone and prolactin in men.

The other study during which the well-trained male participants without any diseases took 500 mg of plant extract daily during the whole study period has also shown the improvement of testosterone levels. This happens due to the extract ability to suppress the enzymes which destroy testosterone.


Black pepper is a source of Bioperine. In fact, Bioperine doesn’t belong to the ingredients which enhance testosterone synthesis. But when searching for a worthy testosterone booster, don’t forget to check whether this ingredient is included to the supplement.

This ingredient is crucial because it enhances the efficacy of the other ingredients which really activate testosterone secretion. Bioperine acts by improving the absorption of boron, vitamin D3, Fenugreek, etc. It means that you will get much better supplementation results.

The Choice of Ingredients: What to Focus on

When looking for the booster with the best selection of the ingredients, you should pay attention to some important aspects.

Thus, don’t choose the supplement with a proprietary blend in the formula. The mixture of such ingredients contains different dosages of each ingredient. And you never know how much exactly. This can be dangerous to your health.

It’s also strongly recommended to avoid the supplements which were developed earlier than a few years ago. The matter is that such products are already outdated and were created without the use of all the most innovative technologies and without a scientific proof.
