You only have one life, why would you choose to do that to yourself. Maybe they don't understand.
My guess is that most of them have no idea about side effects when they start taking the stuff.
They probably get the shit from some male trainer who promises that what they're getting is safe and 'weak'.

And heavier stuff is introduced.
All of a sudden, there is a permanent transformation.
Which probably feels like a one way street for these persons.
It's just fcuking sad.
