The positive result was triggered by elevated levels of testosterone in Braun's system, the sources also told "Outside the Lines." A subsequent, more comprehensive test revealed the testosterone was synthetic -- not produced by Braun's body.
Every individual naturally produces testosterone and a substance called epitestosterone, typically at a ratio of 1-to-1. In Major League Baseball, if the ratio comes in at 4-to-1 or higher during testing, a player is deemed to have tested positive. The sources did not indicate how high above the threshold Braun's sample tested.
