Sylvester Stallone admits human growth hormone use

Sylvester Stallone says he used human growth hormone to get buff for the new "Rambo" movie, and defends its use.

"HGH (human growth hormone) is nothing," the 61-year-old actor tells Time magazine in its February 4 issue.

"Anyone who calls it a steroid is grossly misinformed."

Because it is nearly undetectable, HGH has become a substance of great concern in major league baseball and other sports battling allegations of rampant doping.
