IMHO:
* You don't need to be big/ripped to have taken the juice. Look around the board! 95% of the board members are smaller than Dre, Carrot, Bale, etc. I'd give maybe 30-40% of the board members Edward Norton's size. Many of those people are taking various forms of anabolic steroids.
* The celebs have the time, the money, and the motivation (the "role", the "look", etc), so why wouldn't they? Just because they don't look like professional BBers or WWE wrestlers doesn't mean they don't juice. I'd guess a large number of the people in that list did/do take various pharmaceuticals (including AAS) because they CAN.
I agree with this. And about the rich having all the "perks" of chefs and dietitians and all that, well if you learn about nutrition you will be your own dietitian and a better one than anyone can be - because you know your own body better than anyone.
And as for the rich and famous having superior food - why exactly is Dr. Dre's Fillet of Tuna sauteed to perfection any better than my can of tuna that cost a dollar? Protein is protein and while good healthy food can be made to taste better, its always going to take discipline to get in shape, no matter how rich.
Also while stars have lots of off time to do what they want and train when they arent making a movie, it is a pretty hard lifestyle when making a film. Working 12-16 hour days is not uncommon and has been one of the reasons that many stars turn to coke and other uppers to stay on top of their game. I don't think stars deserve the tons of money they get by any means, but its not an easy job when filming.
First of all anyone over 35-40 probably doesnt have perfect hormone balance so they can get on some form of TRT. All of it can be subcribed by a doctor and most dangers removed. So why would they take the hard road? Because all these peeps love bodybuilding so much? No. Because they have such high moral standards? No. Most have their muscles for show, few do it for the love of it IMO. So steroids is the perfect way to have a great physique and not have to live a lifestyle of perfection. I would say most stars take this route.
Thing is we don't know. Just like that guy at the gym that is jacked - we don't know so we can't say for certain. But i would put money that if you think they "might" be on something and especially if they "got big" for a single movie or in a short time, they are on something.
