Investigating officer Hilton Botha said the substance was found by police investigating the killing of Pistorius’s girlfriend Reeva Steenkamp on Valentine’s Day.

“We found two boxes of testosterone and needles and injections,” Botha said.

Testosterone is on the list of substances banned by the International Olympic Committee.

But defence lawyer Barry Roux said: “It’s a herbal remedy and he can use it and he has used it before.”

Craig Spence, a spokesman for the International Paralympic Committee, said Pistorius was tested twice during the London Paralympics in 2012 and tested negative.

At the games he won gold in the 400m, silver in the 200m and came fourth in the 100m.
