How does an anabolic/androgenic steroid get banned from sport competition?

摘要

What is an androgen (anabolic-androgenic steroid)? Most would state that it is a derivative of the major sex steroid in men and most mammals, testosterone (T). Others might answer in the more generic sense: any compound that is an agonist (or partial agonist) at the androgen receptor (AR). There are seemingly enough forms of T activity available to satisfy the needs of the medical population with oral, buccal, cutaneous patches (really, drug delivery devices) and gels, injectables of various durations (days to months), and implantable forms with a duration of action of 6 months or more.
