The International Cycling Union has today issued a warning to riders, teams and National Federations concerning the black market substance GW501516.
The World Anti-Doping Agency (WADA) requested that athletes from all sports be warned about this substance.
The side effects of this chemical compound are so serious that WADA has taken the rare step of warning “cheats” to ensure that there is complete awareness of the possible health risks to athletes who succumb to the temptation of using GW501516 for performance enhancement.
GW501516 was a developmental drug that was withdrawn from research by the pharmaceutical company and terminated when serious toxicities were discovered in pre-clinical studies. Clinical approval has not, and will not be given for this substance.
However, GW501516 has been available for some months on the black market, through the Internet and elsewhere.
