The extent of the drug abuse by the really big men would make your eyes pop. And not just from the financial side of things. To make the money to fund this sort of huge drug bill leads some of the big guys to get into crime, gay prostitution, selling illegal drugs, and advising people on how to use illegal drugs. And some of them are dead. I've always had the discipline, integrity and strength of character to avoid truly destructive habits and people.
Health comes first.
As important as muscle and might are to me, I've never been willing to put my health and even my life on the line in the name of bodybuilding. In this sense, I practice what I preach. Yes, but only if you really know what you are doing. If you follow the conventional training advice that is promoted by most gyms and bodybuilding publications, you will get minimal or no progress, and will likely follow the same route to failure that millions of others already have. To build a terrific physique and level of fitness from only a few hours' work each week is totally realistic.
