HOLLYWOOD hero-turned politician Arnold Schwarzenegger has defended his use of steroids and said he has no regrets about using performance-enhancing drugs.

The Terminator star has long acknowledged using steroids as a professional body-builder but admits he would not change a thing.

"I have no regrets about it because at that time, it was something new that came on the market, and we went to the doctor and did it under doctors' supervision," he said.
