Youth—with ripped abs and perfect bikini bods—is Hollywood's most precious commodity.
The new issue of Vanity Fair reveals stars of a certain age are turning to HGH, or Human Growth Hormone, to get that youthful glow, and they're naming names.
Among them are 70-year-old Nick Nolte.
And 65-year-old Suzanne Somers, who told INSIDE EDITION's Jim Moret, "The reason I take it is I want to keep my bones strong. I want to keep my muscles strong."
Sylvester Stallone, and famed director Oliver Stone are also named as taking HGH.
According to Vanity Fair, HGH is also used by many other "top stars, filmmakers, and studio executives."
Many of them go to Beverly Hills anti-aging specialist, Dr. Uzzi Reiss, who says he's been injecting himself with HGH for years.
Dr. Reiss said, "I'm 67. Most of my friends are declining. I'm working 12 hours days. I have a full social life."
But the fountain of youth is not risk free.
Drug companies warn of an increased risk of cancer, heart failure, and diabetes. Actress Alana Stewart, the late Farrah Fawcett's best friend, once used HGH but stopped because she was worried about the side effects.
On the Today show, Stewart said, "If there's even a slight possibility that it could contribute to cancer cell growth, I wouldn't put it in my body."
But Nolte says the risks are outweighed by the benefits of ripped abs, fewer wrinkles, heightened sex drive, and more energy.
Stallone once defended his use of HGH in an interview with the Today show.
"It's really archaic the way people perceive HGH. It's amino acids," said Stallone.
And Suzanne Somers has also advocated HGH for years. Somers told INSIDE EDITION's Jim Moret, "Most people are practicing 50-year-old medicine. I'm practicing a brand new kind of medicine."
