I think you should of mentioned how the side effects associated with steroids can be prevented.(Gyno,Hair loss,Testicular atrophy,Liver problems,ect)
If you think you can "Scare" people into not using you're wrong. If the media bullshit you hear all of the time doesn't scare them..Nothing will.
Those who want to use will use. Nothing can be done about that.
The best thing you can do is educate them on proper cycling methods and how to reduce side effects(What this forum dose very well).
Saying you'll go bald and get bitch tits if you use steroids isn't going to work.
