On what date did Major League Baseball put in to effect the ban on Human growth hormone?

Answer 1

They actually call it a "steroid" in the contract for the joint drug and treatment program they ratified as an amendment to the existing CBA on January 13, 2005.

Answer 2

HGH is a joke. It's never been proven to give you any kind of advantage. They should eat it like cereal.
