The questionnaire of 25 questions (Cronbach Alfa 0.84) which was distributed among 320 bodybuilders as sample from different areas of Karaj city. Research data by using the descriptive and inferential statistics (P≥0.05) were analyzed. The results demonstrated 82.4% of these athletes taking supplements. Also, it was found that the level of education, sports history and championship history of participants in this study is significantly correlated with the prevalence of use (P≥0.05). But, there was no significant correlation between level of education, sports history and championship history with knowledge and attitudes. Most used supplement were combination (46%), creatine (21.9%) and protein powder (15.3%). The most important reason for using supplements were, increase muscle mass (54%) and increasing strength (25.6%) and the most important sources of information, were coach (62%) and Teammates (17%).
