Random, unannounced blood tests for human growth hormone will take place three times a year, two during the season and once in the offseason.
Per the AP:
A positive test will result in a 20-game suspension for a first violation and a 45-game ban for a second violation. A player would be dismissed and disqualified from the NBA for his third violation.
Owners and players had agreed during collective bargaining negotiations in 2011 to determine a process for how HGH testing could be implemented. The league hasn’t previously done blood testing.
