Police say they found two boxes of testosterone and needles in the bedroom of Oscar Pistorius' bedroom, but his defense lawyer says it was an "herbal remedy" and not a banned substance.

Detective Hilton Botha made the revelation in a bail hearing Wednesday after Pistorius was charged with premeditated murder in the shooting death of Reeva Steenkamp. Botha said police made the discovery but offered no further details.

Pistorius' lawyer Barry Roux said it was "not a steroid and it is not a banned substance." Roux says police "take every piece of evidence and try to extract the most possibly negative connotation and present it to the court."

An International Paralympic Committee spokesman says Pistorius was drug tested on Aug. 25 and Sept. 8 last year and both were negative.
