Braun became the latest star tripped up by baseball's drug rules.
The sport was criticized for allowing bulked-up sluggers to set power records in the 1990s and only started testing in 2003. Since then, testing and penalties have become more stringent and last year San Francisco's Melky Cabrera was suspended for 50 games, just weeks after he was voted MVP of the All-Star game.
Four All-Stars this year have been linked in media reports to Biogenesis: Texas outfielder Nelson Cruz, San Diego shortstop Everth Cabrera, Oakland pitcher Bartolo Colon and Detroit shortstop Jhonny Peralta.
Other players tied to Biogenesis in media reports include Melky Cabrera, now with the Toronto Blue Jays, Yankees catcher Francisco Cervelli and Seattle catcher Jesus Montero.
"I guess this gives an example to the kids what not to do," Cincinnati manager Dusty Baker said.
