Sorry, but you are wrong. Mike Matarazzo once (jokingly) said that at least half the audience in a show like the Mr Olympia are on more drugs than the competitors themselves! But then very few of them look like the pros onstage, don't they? Going by your theory, everyone in the pro level should be of the same or similar size as Ronnie Coleman of 2003 or Dorian Yates when he weighed 270 lb in 2007. The reason they don't is because of genetics.
At the top level, all pros do similar amounts of juice, yet some are bigger than others. They all have access to the best gyms and there are no secrets with dieting or juicing or training, but there is only one Phil Heath with arms like the ones he has or Dorian Yates with his calves. Johnnie Jackson probably lifts heavier than Dorian does (not that it matters if he doesn't) and even if he takes the same or more of the drugs than what Dorian did, he'll never have Dorian's calves in a billion years.
Throughout their reigns as Mr Olympia, both Dorian Yates and Ronnie Coleman had competitors trying to equal or surpass them in terms of size and muscularity. And save for a couple of guys who had the genetics for it (like Nasser and Jay), no one else could come close to them muscularity wise. Genetics are the reason why you can take someone like Kenny Jones, inject him with everything you can get your hands on and still not have him come anywhere near the shape Ronnie Coleman displayed at his best onstage.
Drugs will help you build more muscle than what you can naturally and do it quicker. But no drugs or training or dietary principles will change your calves to resemble those of Dorian Yates if your calves were 11" to start with, to give an example. Genetics is also the reason why some pros stay healthy (relatively speaking) and retain a head full of hair in spite of mega dosing stuff, while others have their body and organs break down and fail.
Absolutely right!
mike isn't exactly going to come out and tell the truth - i.e anyone could be as big as him if they took illegal drugs too. he's not the only 'pro' to make this claim, yet as soon as they all come off they look like aids victims i.e. prince, titus, levrone, etc
yes genetics does involve a load of things, insertions, structure etc as will said. However your argument that ronnie and yates were special or genetic freaks is simply a guess. you have no clue what they take, and saying that every pro is on virtually the same thing is a guess too, in fact , many like milos, gh15, doggcrapp, priest, disgusted etc all disagree regading dosages. i read kamali and johnny jackson say the dosages chad wanted them to take would kill them - clearly ronnie didn't mind - and funnily enough was the largest ever.
reg park was considered a genetic freak, never to be beaten on size, then arnold, then haney, then dorian, then ronnie. the one thing they all have in common is larger doses.
steroids + training = size
diet + training = cuts
the rest i leave to genetics, which will be reflected in the judging or should i say 'personal preference' in the same way someone compares 2 faces and decides who is better looking.
