Besides setting a bad example by cheating and/or trashing one's body PEDs use can disuade people from working out. People assume all the results these athletes obtain is from the drugs and not the workout routine many of they go through while using PEDs. The benefits of basic fitness and nutrition get lost in the shuffle. There are gains/benefits to be made from simply working out or eating right/taking vitamins.

PEDs use helps/speeds up recovery whichs allows people to workout longer and harder. This also means without a serious strength and endurance workout routine PEDs wind up not aiding many. The benefits of working out and general fitness should never be ignored.
