but still, i'm sure it used to be somewhat more "popular", back when knowledge about steroids was more sparse. now, as others have said, everyone knows this endeavor is very unhealthy.
people will always be interested in having a better physique. now, i think most people look to youtube fitness stars and the like -- probably in greater numbers than ever followed real pro bodybuilders. even the streamers/bloggers generally peddle shady information. they push some "system" that has "worked for them", which they may or may not really follow, and hide behind drugs just as regular bbers.
the "problem" is and always has been fundamental to the activity: focusing on what you look like eventually becomes unhealthy. when you start pursuing a look at the cost of strength, agility, stamina, mobility, etc. you wind up with modern "bodybuilding": a joke.
