  • Increase in libido.

Before we try to understand the science behind the above claims of the manufacturer, we must know about testosterone, the symptoms of testosterone deficiency, testosterone replacement therapy, its side effects, process of testosterone production in the men’s body etc.

What is testosterone

Testosterone is the prime and most important hormone found in male body. This hormone is responsible for the growth of male reproductive tissues which include testes, prostate etc.

Testosterone also promotes other male characteristics such as hairs on the body, lean big muscles, hoarse voice, strength and vigor.

Small amount of testosterone is also found in females which helps them in increasing bone mass and in general well being. Testosterone is useful for improved cognitive functions also in both the sexes.

In males testosterone is produced in the testicles while in women very small amounts of testosterone is produced in the ovaries. The quantity of testosterone in adult men is about 7 to 8 times greater compared to adult women.

In men the metabolism of testosterone production is phenomenal. Daily production of testosterone in men is 20 times higher than in women.

Testosterone has both anabolic as well as androgenic effects. The anabolic effects of testosterone are responsible for the muscle and bone growth, strength, increase in bone density etc.

The androgenic effects of the testosterone is responsible for the maturation of the sexual organs and various secondary sexual features such as deep bass voice, facial hair etc.

Why at all testosterone should decline in men

 Though Nature has given enough provision for the production of testosterone in men, the testosterone levels start declining after the age of 30. The production of testosterone reaches its zenith during the childhood and the adolescence period.

After the age of 30 men testosterone declines at the rate of 1% each year. But the symptoms appear with significance only after 40. In some adult men the symptoms are not pronounced even after declining levels of testosterone.

But some men find testosterone deficiency debilitating. Such middle aged and elderly men need testosterone replacements to live happily and healthily. This phenomenon is known as hypogonadism.

The other reasons of low levels of testosterone

  • First and foremost reason for low levels of testosterone is aging.
  • As testosterone is produced in testicles in men, any injury or infection of the testicles will cause disruption in the production of testosterone, causing low levels of testosterone.
  • Some such metabolic dysfunctioning such as hemochromatosis in which the amount of iron in the body is much beyond safe limit.
  • The pituitary gland sends the signals to the testicle for the production of testosterone. Any dysfunction of the gland or tumor in the pituitary gland may cause disruption in testosterone production.
  • Some medication for the treatment of conditions such as prostate cancer may reduce testosterone levels in men.
  • Severe and chronic ailments.
  • Too much dependence on alcohol
  • Kidney failure
  • Inflammatory conditions
  • In one disease called Kallman syndrome, the hypothalamus gland gets an abnormal growth. The hypothalamus gland of the brain controls secretion of many hormones including testosterone.
  • Overweight or obesity
  • Production of excess estrogen which is a female hormone.
  • Abuses of anabolic steroids.
  • Hypothyroidism
  • Head injury
  • Sleep apnea

Symptoms of low level of testosterone in men

  • Fatigue
  • Chronic tiredness
  • Increase in belly fat
  • Gain in weight
  • Low levels of libido
  • Reduced feeling of well being
  • Loss of memory
  • Depression
  • Irritation and unpredictable mood changes
  • Muscle loss
  • Delayed repair after training
  • Less stamina and drive
  • Declining body hair
  • Mild anemia
  • Growth of breast
  • Infertility
  • Osteoporosis

How can you diagnose testosterone deficiency

 The levels of testosterone can be measured by doing blood tests. The normal levels of testosterone in adult males is 300 to 1000 ng/l. But one should not get nervous simply due to  low levels of testosterone.

The testosterone levels vary throughout the day. The doctors prefer 7 AM to 10 AM because the levels of testosterone remain high during this time.

Many doctors suggest testing multiple times to a conclusive result. A level which falls in the range 200 to 300 is considered a gray area by the doctors. You may not have any symptoms.

Once you have phenomenally low levels of testosterone along with symptoms of low testosterone you will need to enhance testosterone levels.

How to treat testosterone deficiency

 The only available treatment for low levels of testosterone is testosterone replacement therapy. In this therapy synthetic anabolic steroid mimicking testosterone is used to replace the testosterone.

Synthetic testosterone can be applied in various modes such as

  • Intramuscular injection to be given every 2 weeks
  • Patches on the skins to be applied daily
  • Applying gel and rubbing on the skin to be applied daily
  • Pallets which are to be implanted under the skin which is to be done every 3 to 4 months.
  • In the form of tablets ( but this mode is being discarded in various countries )

The duration of the treatment may vary depending upon the needs of the person. Six months may be a reasonable duration for increasing drive and libido.

People having disease of the pituitary gland the therapy is to be continued lifelong.

Side effects of testosterone replacement therapy

  • Fluid retention
  • Oily skin
  • Prostate gland stimulation
  • Development of prostate issues
  • Enlargement of breast
  • Risks of blood clotting
  • Sleep apnea
  • Reduction in the size of the testicle
  • Aggressiveness
  • Mood swings
  • Cardiovascular disorders
  • Blood cell count may increase
  • Lipid profile as well as cholesterol may show changes
  • Infertility due to reduced sperm count
  • More PSA

What is the alternative treatment

Due to the many severe side effects of testosterone replacement therapy most people are scared to resort to such therapy. They are trying to find some alternative therapy which will be effective as well as safe.

Fortunately for the people needing enhancement of the levels of testosterone there is alternative treatment available in modern medicine. Testogen is the novel and simple solution for testing low testosterone syndrome.

Taking cues from the various schools of alternate and parallel systems of medicine which have been practiced by the tribals and ancient people of the world for thousands of years, the scientists have come out with health supplements which are able to enhance testosterone production.

Testogen contains 11 natural ingredients.

The ingredients of Testogen

  • D-Aspartic Acid 2352 mg
  • Fenugreek 40 mg
  • Vitamin D3 50 mcg
  • Zinc 10 mg
  • Korean Red Ginseng 40 mg
  • Boron 8 mg
  • Nettle Leaf Extract 40 mg
  • Magnesium 200 mg
  • Vitamin K1 20 mcg
  • Vitamin B6 20 mg
  • Bioperine 5 mg

 Science Behind the Claims of the manufacturer

In order to look for the science behind the claims of the manufacturer of the health supplement Testogen, we have to delve deep into each of the ingredients.

D-Aspartic Acid

To understand the effects of this bioactive phytochemical we have to know the process of the production of testosterone in men. The secretion of the testosterone hormone and for that matter for a number of hormones, the pituitary and the hypothalamus glands play vital roles.

In the production of testosterone the pituitary gland sends signals to the testicles for starting the production process. The pituitary gland performs this action through a hormone called Luteinizing Hormone. This Luteinizing Hormone in turn triggers the Leydig cells which are there in the testicles to produce testosterone.

So if we are able to enhance the quantity of Luteinizing Hormone in the pituitary gland it will be possible to enhance the production of testosterone.

Now D-Aspartic Acid which is basically an amino acid, supports the Luteinizing Hormone Production. So by enhancing the production of Luteinizing Hormone D-Aspartic Acid helps in increasing the levels of testosterone in the male body.

To support such vital action of the ingredient D-Aspartic Acid manufacturer of the supplement Testogen has included more amount of D-Aspartic Acid to the extent of 2352 mg which is rarely found in other competing supplements.


 In our body there are some enzymes which are after the conversion of free testosterone into estrogen which is primarily a female hormone.

Fenugreek contains some particular compounds which can inhibit this conversion process by binding itself to the enzymes responsible for such conversion of testosterone to estrogen.

Many clinical studies have been done to confirm this activity of the compound in the ingredient Fenugreek. All the studies have confirmed that fenugreek does play a significant role in improving the levels of testosterone in men.

The participants of the study have improved a lot with regards to energy level, strength & stamina, well being, belly fat and libido.

Vitamin D3

Scientists have found a close relation of vitamin D3 with testosterone levels. The people with high amounts of D3 have been found to have sufficient levels of testosterone while the opposite is true for the people with D3 deficiencies.

That is why the manufacturers of the supplement Testogen have included vitamin D3 in the supplement so that the users of the health supplement can get a regular dose of vitamin D3.

This aspect of the supplement will ensure that the user never goes down on vitamin D3 which is a must for the production of testosterone.

The supplement Testogen provides the vitamin D3 in the form of cholecalciferol which is considered as the best form of vitamin D3. Furthermore, the manufacturer of the supplement Testogen has cleverly included other ingredients such as vitamin K and magnesium for some specific reasons.

Because vitamin D3 becomes much more effective in enhancing the testosterone levels in conjunction with vitamin K and magnesium. Thus we find the selection of the ingredients does have some concrete scientific basis behind it.


Zinc is a trace mineral which our body requires for many vital functions. As the amount of such minerals which is required for the body is minimal hence we call such minerals as trace minerals.

It has been found that zinc has a close link in the production of testosterone in the body. But we do not get much of the trace mineral from our food leading to zinc deficiencies.

This is the specific reason why the company added zinc in the supplement so that the users get some zinc for their body. Zinc has other beneficial effects such as improving immunity and fighting infections.

Regular intake of zinc through the supplement helps you to increase testosterone production.

While studying how zinc helps in enhancing the levels of testosterone it was found by the scientists that zinc acts as an antioxidant. We all know by now that sometimes our body is infested with free radicals due to various reasons.

These free radicals are very harmful for the body. The free radicals are responsible for the oxidative stress. Free radicals also damage tissues and organs.

In the case of testosterone production, leydig cells play an important role. Due to the oxidative stress such leydig cells get damaged. Damaged leydig cells cannot produce testosterone lowering its levels in the body.

Zinc’s role here is to eliminate the free radicals and reduce oxidative stress. In this way the trace mineral zinc helps in recovering the health of the leydig cells which in turn helps in the production of testosterone.

The form of zinc used by the formula of the supplement Testogen is zinc citrate which is absorbed fast and in a better way by the  body. Thus we find that the designers of the formula for the supplement have rigidly kept science behind them.

Korean Red Ginseng Extract

This ingredient is also known as Panax Ginseng. Ginseng is one of the most popular medicines of the alternative system of medicines. For thousands of years this ingredient has been used by the ancient people for treating many ailments such as low energy, diminished libido etc.

Modern science has found that the ingredient has a significant effect in enhancing the levels of testosterone as well as in increasing libido in men.

Ginseng contains one compound called ginsenosides which is thought to be effective in imparting beneficial effects on the body.

The scientists also observed that ginseng has an effect in increasing the levels of neurotransmitters such as dopamine and acetylcholine of the brain. Brain neurotransmitters are linked with mood and various other cognitive functions.

Ginsenoside also has other beneficial effects of enhancing the levels of nitric oxide in the body. Enhanced nitric oxide in the body increases blood flow to the different organs of the body.

More blood means more oxygen to various tissues improving the functioning of the whale body. 


Boron is another very essential trace mineral which our body needs in small amounts. It enhances the levels of testosterone by increasing the testosterone metabolism. More and more total testosterone of the body gets converted to free testosterone.

Free testosterone is the form of testosterone which gives immense benefits to the men’s body. Scientists have found that boron inhibits the production of Estradiol which is a form of estrogen, the female hormone.

At some point of time the men’s body starts converting a large amount of testosterone to estradiol which is not good for men. This phenomenon reduces the levels of testosterone in the body.

SHBG is another hormone which binds to testosterone making it ineffective for the body. It is important to put brakes on this. Boron has been included very intelligently by the designers of the formula of Testogen to perform this very job.

By binding itself to SHBG it helps in increasing the levels of free testosterone. You get more energized, well focussed and full of stamina and drive.

Boron has another important function for the proper absorption of other ingredients of the supplement. Boron helps in the fullest absorption of magnesium and vitamin D3. Both these ingredients are included in the supplement.

Nettle Leaf Extract

We have heard that sex hormone binding globulin or SHBG get itself bound to testosterone making the effects of testosterone blunt. There is one compound called ligans in Nettle leaf extract which prevents SHBG from binding to the testosterone.

In this way nettle leaf extract helps in freeing the testosterone means increasing the amounts of free testosterone in the body. It also prevents the free testosterone from getting converted to estrogen.


Magnesium is such a mineral which seems to love those men who are fond of exercising. It has been found in studies that in people who are on exercises magnesium helps significantly in enhancing the testosterone levels.

Unfortunately most of the people do not get enough of magnesium through food and the men fail to get the effects of the mineral. This is particularly true for the elderly men who are again at risk of low levels of testosterone.

The formulation of Testogen finds enough amounts of magnesium to do away with such conditions. The supplement contains 200 mg of magnesium per dose so that the users of the supplement Testogen get enough magnesium to restore the levels of testosterone.

Vitamin B6

It is a part of the group of vitamins which we call vitamin B complex and is often prescribed by the doctors for weakness, muscle ache and various bone health.

Many studies have been done to understand the connection of vitamin B complex with the testosterone levels. It has been noticed that vitamin B complex deficiency is closely linked with low testosterone as well as high estrogen levels.

So it is concluded that vitamin B complex enhances testosterone levels and decreases the levels of estrogen which is a female hormone.

It is also essential for the general well being of the users. The elderly persons must get regular doses of vitamin B complex for the restoration of the testosterone.

Vitamin K1

Vitamin K1 makes the effects of vitamin D3 more pronounced.


This ingredient is included by almost all the supplement manufacturers for its bioavailability. It enhances the bioavailability of the supplement Testogen by 30 %. It enhances the rate of absorption of all the ingredients.

Miscellaneous ingredients

For the capsules the manufacturer uses Hypromellose making the capsules suitable for the vegans.

Maltodextrin, silica and magnesium stearate are used for the flow and anti-binding effects so that the capsules do not get attached.
