Ryan Braun's relationship with Tony Bosch and Biogenesis began during the summer of 2011, according to a report by ESPN's T.J. Quinn.
The link was established several months before the October 2011 drug test which would trigger Braun's long battle with Major League Baseball.
Quinn's sources allege Braun "was on a performance-enhancing-drug regimen for high-end clients," including mint- or cherry-flavored lozenges containing testosterone that a user would place under his tongue.
