Once again an athlete has admitted using steroids despite testing negative numerous times. Marion Jones the olympic sprinter said she used steroids before the 2000 olympics where she won numerous medals and continued using them in world competitions where she tested negative a number of times. One test however came back positive but the back up test came back negative so she was declared clean.
There is a long list of athletes who test negative through out their career only to admitt using steroids later on.
The fact that the labs can be so wrong or inconclusive proves what ? Does it bolster Landis claim to be clean ? Does it call into question Lance Armstrongs clean test results ?
