TELL-ALL BOOK: Conrad Murray

Michael Jackson apparently received injections at 13 to keep him from growing up.

The Thriller hitmaker’s former doctor, Conrad Murray, claimed Jackson confided in him about the hormone treatment he had received in his early teens, meant to delay puberty and keep his voice high.

Murray was jailed for involuntary manslaughter after administering the fatal dose of Propofol which killed the King of Pop in June 2009.

Writing in his new book: This Is It, Murray  who met Michael three years before his death  said Michael was vague when he made the “cathartic confession”.

“But what Michael said left me the impression that he had been given injections, probably hormones, to delay puberty.”
