Young guys will always have the more the merry attitude when it comes to drugs , if 700 is working than 1000 would do better. And when you have guys like Bostin Loyd telling them that who are they going to listen to anyway? Even if they were trying to downplay the dosages it's not likely to convince any young guys anyway
Dorian has always been a straight shooter it's his nature. When he was competing he admitted he was on steroids but he would never disclose the dosages. Well after he retired and his supposed cycle was disclosed and he addressed it as bullshit ye still didn't disclose the amounts. Now that he has , people don't believe it. I think this speaks on them more than the Pros who do admit it.
It's no coincidence that the guys back then trained harder and looked better. Dorian as many people have said is a very straight forward no nonsense type of guy , Kevin Horton who has known him for 30 years has said he's the most honest person , especially in a sport where a lot of shit if talked. Dorian was one of the first people to call out Victor Richard's 30,000 calories has bullshit. Shaw as well has always been known as a person who didn't hold back , even when competing he said he wasn't going to take it to the limits other guys would and mentioned Nasser by name.
In the end the only person who knows is the pro themselves. What does he have to gain by lying?
The whole bodybuilding industry is built on deception. Dorian has his own supplement company/line that didn't exist when he was competing yet he's using the Mr.O winning build to sell his products.
As someone here said much better than I can paraphrase, Kevin spent years as being a runner up in the sport he devoted his life to, his pushed the physical limits of his body, but he didn't experiment with using more drugs, whatever he claimed he used was the "sweet spot" for growth....... yet he hasn't revealed the same information with food consumption, weight poundages/exercise selection, and so on.
No doubt these are good dudes, who are all time greats and are extremely knowledgeable about the contests they dominated, however they would have a lot to lose if they were completely honest about their drug regimen, I mean one of Dorian's two losses came against a guy who died after winning the show.
Arnold said steroids are just the finishing touch, yet he's never revealed what he took, why? The answer is because the general public has no idea how much these guys sacrificed to get to that level, and they'd be shocked, even appalled if the truth did come out.
*Mike Morris did a video where he talked about his drug use, and no one questions him. Genetics are undoubtedly the most important factor, no amount of drugs or training will make someone a champion if their body/talent isn't there.
As you said some use more some use less, life isn't fair, but ultimately we don't know.
