Testosterone Hormone ID 1
As a steroid hormone produced naturally by the body, testosterone is a key component in maintaining health.
Testosterone stimulates growth in parts of the body sensitive to androgens, promoting muscle and bone development as well as growth of those parts of the body with specific gender characteristics.
Testosterone is primarily administered to treat conditions associated with hormonal deficiency but in sports its anabolic, growth effects are most sought after, where the synthesis of proteins in muscle tissue is significantly accelerated.
Testing
The most common anti-doping test is that of measuring the testosterone / epitestosterone ratio in a sample of an athlete's urine.
The limit of this ratio is normally set at 4:1 and in positive test results, that level has often been much higher.
Tests may also demonstrate that the testosterone found in the sample has synthetic rather than natural origins, thus generating clear evidence of doping.
