Sylvester Stallone

Hollywood movie star Sylvester Stallone admits he used Human Growth Hormone, HGH, to improve the appearance of his body for his latest Rambo movie, and does not think it was wrong to do so.

In an interview with Time magazine, the 61-year-old actor says HGH is not a steroid, and he says everyone over the age of 40 should look into using it because it increases testosterone in the body and improves quality of life.

The latest installment in the Rambo series, which Stallone directed and co-wrote, opened in the United States Friday. 

Many sports in the U.S. have come under scrutiny because of allegations that top stars have used steroids and HGH to improve their performance even though most professional sports organizations ban their use.

Stallone says opposition to the use of HGH and testosterone will someday change, predicting that "In 10 years it will be" available without a prescription.
