Personally to me the compounds are the last factor in what it takes to be a pro. It takes genetics for a base. Countless years of hard work, dedication, discipline, education, execution, training, eating, dieting, refineing, sacrifice. To me all of this is what makes the pros a cut above. There bodies didn't just happen from having bad ass genetics(which they do) nor did their bodies come from slamming a few cycles together and then walking onstage. It took them years of hard work to achieve what they have and the drugs simply support their work ethic.
