The substance found in Oscar Pistorius' bedroom following the death of his girlfriend, originally said to be testosterone, was an herbal remedy used to aid muscle recovery, according to the UK's Daily Mail.
A Pistorius' family spokesperson, Lunice Johnston, said the substance was Testis compositum, which is also marketed as a sexual enhancer which can improve stamina.
A tablet form of the herbal remedy contains 23 ingredients, including pig testicles, pig heart, pig embryo and pig adrenal gland, cortisone, ginseng and other botanicals.
Pistorius is charged with murdering his girlfriend, Reeva Steenkamp, in the early hours of Feb. 14 at his luxury home near Pretoria. He says he fired four shots into a locked bathroom door in the mistaken belief that an intruder was lurking behind it.
Pistorius is out on bail, staying with his uncle in Pretoria awaiting trial. He faces life in prison if convicted.
