How Andreas won gold as doping-victim Heidi.

Having been crowned European shot put champion in 1986, Heidi Krieger was one of the stars of the former GDR.

But having been subjected to a doping program like thousand of other former East German athletes, Krieger realised on her 1990 retirement that the effects of testosterone hormone abuse had left her with all the traits of a man.

She opted for a sex change operation and is today known as Andreas whose birth certificate has been altered and, sporting a moustache, he now owns an army clothes shop in Magdeburg.

The confident, strapping man of 1.87m shows a copy of his photo from his competition days as Heidi, and a timid girl stares out from the image with short brown hair and broad shoulders hidden in a tracksuit.
