Former European 1,500metres champion Sureyya Ayhan Kop has been banned for life from athletics by the Court of Arbitration for Sport.
The Turkish athlete failed a drugs test in September 2007 when a sample she gave revealed stanozolol and methandienone metabolites.
It was Kop's second doping offence after she obstructed a test in 2004 before the Athens Olympics.
The 31-year-old, who won the 2002 European title before coming second at the following year's World Championships, was initially given a lifetime ban by the Turkish Athletics Federation although that was subsequently reduced to four years by the Arbitration Tribunal of the General Directorate of Youth and Sport.
Her husband and coach Yucel Kop was also banned for two years by the TAF for negligence which was confirmed by the Arbitration Tribunal.
Athlete and coach filed appeals with CAS requesting the annulment of the tribunal's decisions while the International Association of Athletics Federations wanted a lifetime ban.
While the life ban was imposed on the athlete, CAS lifted the suspension imposed on her husband was lifted as there was no evidence to say he had violated any disciplinary or anti-doping rule.
