Courtney Love is so desperate to fight the aging process, she has started taking human growth hormones, insiders say.

The former Hole rocker, 45, reportedly takes a daily dose of Genotropin in a bid to look younger.

The hormone may also be responsible for Love’s recent shock weight loss.

“Courtney has been struggling with her weight,” a source told Britain’s Mail on Sunday newspaper.

“She’s been using the hormones to help her gain muscle and for anti-aging and likes the results.

“But she’s not very discreet. She even left a vial of it in her LA hotel room.”

A spokesman for Courtney — the widow of Nirvana frontman Kurt Cobain — said he was not aware that she was taking the hormone.
