The 37-year-old singer said that he used testosterone jabs to kill his lethargy. “It has changed my life. I feel I’m getting a second wind,” he told to British Tabloid TheSun.

He said, “To cut a long story short I went to get some HGH. It’s what all the old fellas are on out there in LA that’s making them look 40 instead of 60.

“It’s improving their health, their memory, their hair, skin.

“Could give you cancer. I weighed that up. Thought I’d have it anyway. Went to see a Hollywood doctor.

Had my blood tests. Went back. He added, ‘You don’t need HGH. You’ve got the testosterone of a 100-year-old man.’

“And then everything made sense. It was kind of an epiphany that day.”
