London: Singer Robbie Williams says he has experienced change after he started injecting himself with a sex hormone twice a week.
The 37-year-old admits he uses testosterone jabs to fight crippling lethargy, reports a website.
"It has changed my life. I feel I`m getting a second wind," said Williams, who took to injections after a doctor told him he had the sex drive of a 100-year-old.
The singer had visited the doctor for some Human Growth Hormone (HGH) - popular with wealthy middle-aged men trying to battle the march of time. He had blood tests in Los Angeles that showed he had extremely low levels of testosterone - a hormone that boosts sex drive.
So, Williams began injecting himself with testosterone twice a week.
"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 said, `You don`t need HGH. You`ve got the testosterone of a 100-year-old man`. And then everything made sense," he said
Williams has now been injecting himself for two years.
