Usain Bolt on the track

The Daily Telegraph of Australia has reported on rumors that Selective Androgen Receptor Modulators have been used during the Berlin World Championships:

The word out of Berlin last night was that the PED of the day is SARMS (selective androgen receptor modulation). The most popular version is Ostarine which has the body building qualities of an anabolic steroid but does not touch the athlete’s endocrine profile and is thereby undetectable in current tests.

SARMS have been available in limited supply on the United States market for the past few years, and their widespread use in sports doping has been both predicted and speculated, although this is the first recorded incidence of their use at a specific event.
