What are anabolic steroids?

Anabolic steroids are substances with an action similar to that of the male hormone testosterone. Substances, like the hormone, by binding to specific cell receptors induce typical changes related to sexual differentiation, mainly an increase in muscle mass and strength.

In the synthetic steroids the masculinizing effect is reduced but maintaining the stimulating effect on the protein metabolism (muscle matrix deposition). Doping doses (50-200 mg per day) are ten times higher than those recommended for therapeutic use. You can take it by mouth or by injection delay.

In the United States statistics on the use of anabolic steroids are available: between 92 and 93, at least 500,000 people have used steroids, with an estimated turnover of 100 million dollars a year. At least 1 boy out of 15 has used it; 25% of these boys invoked a purely aesthetic reason for taking substances.

The intake of steroid hormones induces an increase in muscle mass and this, in turn, allows you to tackle heavier workouts and consequently more marked improvements resulting from training itself in shooting and power tests. In addition steroids induce reduction of fat mass. Intake of steroid drugs inhibits endogenous testosterone synthesis. In a study conducted on weight lifters taking anabolic steroids it was found that at the cessation of administration, plasma testosterone concentration was reduced to half of normal and remained lower than normal for 12-16 weeks.

They include substances with anabolic effect when administered systematically (salbutamol, salmeterol, terbutaline, beta-agonists).
