It takes the same amount of time because human behavior hasn't changed.
It's kinda like the big massive mistakes men make by dating certain people, for example almost 100% of the time if you date a junkie, single mom, stripper etc things will end up in a massive disaster. The information and warnings are out there all over today yet more than ever people feel they know better.
How about the dangers of smoking? More warnings and info about the topic than ever before, the crackhead know it all will contiue to smoke, after all he knows someone that is 180 years old that smoked 16 packs a day since they were 9.
Bodybuilding is same BS. So much good honest info out there, the real info is not what people want to hear just like the guy refuses to hear that as nice as that strippers ass is, dating her seriously will lead to hell. He feels the stripper he met is the exceptions o the rule.
So yea, to make quality gains you must eat real meals not drink shakes, you must train properly and consistently, the quick 7 minute programs won't do much for ya.
As far as drugs go, well I don't advocate it, however every beginner is convinced that dbol and creatine is all one needs, after all who wants to hear about needles and expensive chemicals.
Sorry for going on and on, however, the first step to becoming sane is to realize how we are pre-programmed to be completely insane.
