A substance found in the room of accused murderer Oscar Pistorius was not testosterone, but a herbal sex remedy, South African media have reported.
The "Blade Runner" star, who gained attention at the London Olympics, has been charged with the premeditated murder of his model girlfriend Reeva Steenkamp on Valentine's Day.
Steenkamp was shot through the door of a bathroom at Pistorius' home, but a judge on Friday bailed the 26-year-old sportsman to his uncle's Pretoria home.
Today AFP reported City Press as saying the substance police found in the accused's home following Steenkamp's death was not testosterone.
It was a legal mix of herbal cures made partly from animal organs and was used to boost sexual energy, AFP said.
The prosecution claimed the substance had been testosterone, but the defence said the remedy was known as testocompasutium coenzyme.
The National Prosecuting Authority is testing the substance to determine what it is.
Meanwhile, Pistorius' elder brother, Carl Pistorius, is also facing charges over the death of a woman in a traffic incident five years ago.
Carl Pistorius is charged with culpable homicide in the death of a motorcyclist in 2008. His family said he maintained his innocence.
A family statement said Carl appeared before a judge on Thursday and would be in court again in late March. His younger brother was freed on bail on Friday after a week of hearings watched by the world's media.
The family statement quoted lawyer Kenny Oldwage as saying: "There is no doubt that Carl is innocent and the charge will be challenged in court. Carl deeply regrets the accident.
"Blood tests conducted by the police at the time proved that he had not been under the influence of alcohol, confirming that it was a tragic road accident after the deceased collided with Carl's car."
Contacted by Reuters, Oldwage declined further comment. The family statement said charges had at one stage been withdrawn but then reinstated.
Carl Pistorius attracted little publicity until the arrest of his younger brother propelled the family into the glare of a global media spotlight. He and their younger sister Aimee and father Henke appeared in court to support Oscar, who denies the charge, saying he believed he was shooting at an intruder.
