A substance found in star athlete Oscar Pistorius's home during a search by police probing the killing of his girlfriend is a herbal remedy for muscle recovery, his publicist said Wednesday.
The remedy which can be bought online, including on Amazon.com, is marketed as a homeopathy remedy used for temporary muscle relief and symptoms associated with male sexual weakness.
"We have had confirmation from Oscar's legal team that the herbal remedy that he used was called Testis Compositum - which is used to aid muscle recovery," his spokeswoman Janine Hills told AFP.
The prosecution claimed during the Olympian medallist's bail hearing last week that police had found two boxes of "testosterone" and needles, but the defence had countered that it was a legal herbal remedy.
Prosecutors said they were awaiting the results of forensic tests to determine what the product is.
Pistorius, 26, an Olympic and Paralymic hero, was freed on bail on Friday ahead of a trial on a murder charge over the Valentine's Day killing of his girlfriend Reeva Steenkamp.
The International Paralympic Committee said the double amputee was tested twice during the London Paralympics in 2012 and tested negative.
