Testosterone preparations. The role of testosterone
There are several male hormones – androgens, the main of which is testosterone. It controls the work of body systems, even affecting creativity, way of thinking, intelligence, energy and behaviour. Not to mention its impact on human health and life expectancy. It is a hormone that is produced in the testes, in special Leydig cells. In the testes, sperm also forms in cells of another type – Sertoli cells. The coordinated work of these two types of cells ensures normal sexual and reproductive function in men.
The role of this drug in the body
The role of testosterone in the male body is difficult to overestimate. It has anabolic and androgenic effects. Below we look at the main effects of this drug. First of all, it promotes the growth and development of both the whole body of a man and his reproductive system. Under its influence, there is an increase in the hairline on the body of a man. And also the type of pubic hair growth is formed according to the male type. But, oddly enough, it is testosterone at a more advanced age that affects the formation of bald spots.
Testosterone in different age groups
In adolescence, it is responsible for a growth spurt and the so-called breaking of the voice. This occurs when, under the influence of male hormones, the vocal cords increase in thickness. As a result of this process, the timbre of the voice is reduced. The main effect of this drug, which athletes use in bodybuilding and sports, is muscle growth. The hormone takes part in the processes of protein synthesis and hypertrophy of muscle fibres. It is this property of testosterone preparations that will be used in official medicine. There, anabolic steroids are used in the treatment of cachexia for cancer, after serious injuries or burns.
Accordingly, if there is a lack of this drug in the body for one reason or another, the muscles will atrophy, and the strength of the body will gradually decrease. Testosterone is also important for the skeletal system. This hormone affects the metabolism of calcium and phosphorus in the body. With a lack of this hormone in older men, osteoporosis often develops. One of the causes of sexual desire is a rapid increase in testosterone in the blood. Throughout the day, the volume of this substance in the human body can vary. However, the highest level of this hormone is usually in the morning, and the lowest – in the evening and at night.
Influence on the behaviour of the person
The hormone also affects the behaviour of a person, the state of his central nervous system. It is responsible for the formation of libido and human mood. Also, a high level of testosterone improves the ability to concentrate and make decisions. Analytical thinking also improves under the influence of this male hormone. With a decrease in its levels, memory and reaction rate decrease, spatial orientation worsens, performance and overall vitality decrease.
Reducing of the testosterone levels
The amount of testosterone in the blood can also change with ageing. So, most often a decrease in the level of this hormone happens after 30 years. In most cases, this is accompanied by a decrease in interest in sex, a deterioration in erection, and impaired muscle tone. As a result, by the age of 50-55 (and in some cases even earlier) the hormone content can be only about 1/2 of its amount at a young age. In addition, with age, the amount of a particular protein in the blood, which binds sex hormones, increases, which also leads to a decrease in biologically active testosterone.
Types of testosterone drugs
Testosterone among all anabolic steroids has the largest number of derivatives and release forms. This is as drug esters, such as Testosterone propionate, enanthate, cypionate, phenylpropionate. So are the mixes of various esters, which include Sustanon and Omnadren. It is also available in the form of tablets for oral administration, and a gel for external use. Below we will examine in detail various preparations of this drug, their positive and negative effects. Let’s start with Testosterone Propionate.
Testosterone propionate is one of the most popular steroids in bodybuilding, it’s a means for rapid muscle growth. It was designed to develop muscle mass and strength. Due to the nature of the action, athletes usually use it during the drying period. It has a short action time. Injections are usually performed every other day. This is one of the main disadvantages of using propionate, in comparison with its more long-lived counterparts, for example, with enanthate. Sportsmen can use it both when working on the mass and during the drying period. Another feature of the drug is that, with the right dosages for most athletes, it does not retain water in the body or these manifestations are minimal. The drug suppresses its own production of testosterone, which usually goes back to normal at the end of the course after 2-3 months.
Testosterone Enanthate is an ester of natural testosterone. In bodybuilding, it is one of the most popular steroids for gaining muscle mass. Testosterone Enanthate is a long-acting steroid. Perhaps the main advantage of testosterone enanthate is a pronounced increase in both muscle mass and strength. Along with the anabolic effect, the drug has a pronounced androgenic effect. Rapid weight gain occurs with a significant accumulation of water, due to sodium retention and estrogenic action. At the end of the course, a tangible rollback phenomenon can happen.
Testosterone Cypionate is one of the longest testosterone esters available today. Its half-life in the body is approximately 15 to 16 days (half-life is 6-8 days). The drug is available in the form of an oil solution. The disadvantage of testosterone cypionate is that it aromatizes, or in other words, turns into estrogen.
