Testosterone Definition

Everyone has already heard of Testosterone and for good reason: it’s the miracle hormone for gaining muscle!

But do you really know what it is?

Its chemical formula is C19H28O2 and its melting point is 155°C.

Testosterone defines our sexual characteristics; it has enormous influence on our everyday lives. The first hairs of adolescence, voice changes, the first erection.  Sexual desire in young and not-so-young adults.

Testosterone plays a large role in our physique (our muscles and physical condition), our mind (stress, competitive spirit) and our libido.

Some use testosterone-based treatments simply to revitalize a failing libido. Others use it within an anabolic steroid cycle to increase their athletic and physical performance or simply to feel good about themselves.

Let’s go into more detail about testosterone, its role, its uses, how to use it…everything you need to know can be found on Testo-Steroids.com

 

What is Testosterone?

Testosterone plays a key role in health, well-being, sexual function and blood cell production. An androgenic hormone steroid, testosterone is naturally secreted by the testicles and by the adrenal glands in smaller quantities. It’s the main male sex hormone and the “original” anabolic steroid.

Here is a small, simplified “identity card” for testosterone that should help you understand this hormone.

This table, simplified as much as possible to give you a general overall view of testosterone, its origin, its effects, its purpose and its receptors. We will elaborate on these aspects in the following pages.

 

Testosterone levels in relation to age

For example during adolescence testosterone is responsible for the growth of sexual traits:

  • Increased size of testicles and penis
  • Hairiness
  • Increased muscle mass
  • Interest in sexuality
  • Appearance of so-called erogenous zones

One of the signs of puberty is genital activity. When entering an erection, the penis will allow the emission of sperm and form sperm cells and spermatic fluid. The first hairs appear on the lower abdomen and then on the face, torso and limbs. Growth accelerates, shoulders, musculature develops. The voice becomes lower after the larynx grows (voice change).

These phenomena occur between ages 12 and 16.

The body experiences increasing testosterone levels until reaching its peak around the ages 25-30. This explains why this age group is more intensely interested in sex!

The the levels will gradually begin to decrease according to the rhythm of your biological clock. This is why after the age of 40, supplementary testosterone treatments are used to revive libido.

These rates differ according to the time of day as well. Over a 24 hour cycle, your testosterone levels generally peak in the morning.

 

Testosterone in the body

Testosterone is derived from cholesterol, distributed to the tissue by the blood, and connected to a specific transport plasma protein, “Sex Hormone Binding Globulin”(SHBG).

Sleep contributes to testosterone regeneration; a lack of sleep can have a negative impact.

Testosterone levels in the blood peak in the early morning.

The anabolic properties of Testosterone make it one of the most widely used doping products, whether by athletes who want large muscle mass gains or an older person who wants to regain libido.

It lets you work out more often and get maximum effects from strength training.

Now that we’ve talked about the role of testosterone in adolescents and athletes, lets not neglect the elderly.

Testosterone also plays a role for them.

Taking testosterone after the age of 40 is beneficial, not just sexually but in general, and particularly for the heart and blood vessels. However after turning 40 it is important to have your prostate checked before taking testosterone.

Although it can’t prevent you from getting older, it does play a significant role in:

  • Diminishing fat mass 
  • Increasing libido
  • Increasing muscle mass

 

Types of testosterone for a treatment

Scientific advancements have made a variety of different testosterones available on the market. 

Cypionate, Propionate, Enanthate, Phenylpropionate, Iso Hexanoate and Decanoate are some of these forms. We’ve left out plenty, but we will go into this more deeply on our esters page.
