Oscar Pistorius' representatives have named the substance found in his bedroom after the shooting death of his girlfriend as Testis compositum, and say it is an herbal remedy used "in aid of muscle recovery."

A product called Testis compositum is also marketed as a sexual enhancer, good for lack of stamina. Some online retailers advertise oral and injectable forms as testosterone boosters.

South African police say they found needles in Pistorius' bedroom along with the substance, which they initially named as testosterone. Prosecutors later withdrew that statement identifying the substance and said it had been sent for laboratory tests.

Pistorius family spokesperson Lunice Johnston said in an email to The Associated Press on Wednesday that the athlete's lawyers confirmed that the substance is Testis compositum.
