Anthony Bosch, former owner of the anti-aging clinic Biogenesis in Coral Gables, in August pleaded not guilty to charges of selling illegal steroids to baseball players.

In October, Bosch will plead guilty to those same charges. He signed a plea agreement Wednesday admitting to criminal activity at Biogenesis. 

Bosch and six others were arrested last month on charges of conspiring to sell illegal steroids to professional and high school baseball players.
