Duchaine began competitive bodybuilding in his home state of Maine in 1977; however, after he had no luck (describing himself as a "miserable bodybuilder"), he began using anabolic steroids that he persuaded his family physician in Portland to prescribe as a training aid. However, after beginning their use he said "I still wasn't very good. Obviously something wasn't working, and the doctors and the pharmacists couldn't really answer my questions. So I started looking into steroids on my own." This was the start of the quest for knowledge that would eventually land him the title of "Guru" on the subject. He moved to Los Angeles in 1978.
