Brief summary
Testosterone abuse is extremely prevalent in athletes globally and especially in the United States professional sporting leagues
Detailed description
Because human bodies make testosterone naturally, it can be difficult to determine whether the testosterone in your body is natural or if it came from administering testosterone. Currently, testosterone abuse by athletes is detected by anti-doping laboratories in urine samples and use can also be inferred by testing blood samples. As a pharmaceutical preparation, testosterone is available to administer to your body in different ways. However, due to lack of controlled data on the various preparations of testosterone administrations related to the anti-doping field, this study id designed to look at five different testosterone preparations delivered three different ways and how they compare to each other in terms of anti-doping detection and how long they will be in circulation in your body.
Interventions

A daily dose of testosterone gel
A twice-daily pill of testosterone pill to swallow
