Intranasal Delivery of Testosterone and Its Effect on Doping Markers

Summary

Hypothesis: Intranasal administration of exogenous testosterone results in a characteristic profile during anti-doping testing, which is different than the profile seen when testosterone is administered into muscle, on skin or under the tongue. Objective: The investigators aim to characterize the unique steroid doping profile following administration of intranasal testosterone to healthy, active volunteer subjects.
