During the course of the second day of Pistorius's bail hearing, police described what they found in the athlete's house after the death of model Reeva Steenkamp.
Investigating officer Hilton Botha told the court that police had found two boxes of testosterone and needles in the bedroom.
Defence lawyer Barry Roux said the box contained a herbal medication, not testosterone, and ascertained that the officer mis-read the label in the darkened room.
Botha told the court that a gun holster was found on the left side of the bed where Steenkamp’s slippers and overnight bag were lying.
According to Botha, Pistorius illegally possessed .38-caliber ammunition in a safe in his bedroom; but the defence lawyer said it belonged to the athlete's father.
In the safe there was also a memory stick containing details of offshore accounts and a house in Italy, according to prosecutors - the defence claims that he does not own such a house.
Botha said he discovered a firearm on the shower mat, one bullet cartridge in the passageway and three in the bathroom.
Mr Roux told the court that there was a spent bullet inside the toilet bowl, which Botha had failed to find.
An iPhone 4 and iPhone 5 were both found on the shower mat, neither of which Botha said were used to call the ambulance.
Roux told the court that Pistorius had called Netcare hospital at 3.20am and the housing complex manager received a call asking for help.
Botha found Steenkamp’s body lying on the ground floor at the bottom of the stairs.
Botha told the court Steenkamp was dressed in white shorts and a black top and covered in towels.
