Oral is one thing, I specifically mentioned injectable steroids though. Athletes all over the world get sports related injuries every day and a lot of the other stuff you pointed to is minor/ anecdotal and not backed up by medical studies.
Well, have you personally known any lifters who suffered a muscle tear? It's a career ending injury. It's like who are you trying to kid. Muscle tear injury while lifting a massive weight in an exercise by a steroid user isn't caused by arthritis or the flu.
I get injured regularly, ankle sprain, hamstring pull, etc. All minor injuries. I've even had major injuries, concussion, ACL tear, torn shoulder labrum. I've been in sports all my life. You are comparing apples to oranges. It is rare and/or difficult for a steroid user to get back into bodybuilding after a muscle tear injury.
I'm not saying there are zero side effects, I'm saying that they are much safer than most people realize and much safer than many other things which are legal.
Just because it takes a long time for negative side effects to take place doesn't mean something is safe. You can drink massive amounts of alcohol for decades before you permanently ruin your liver and require a transplant. Alcohol is legal too.
You can choose to take care of your body or not. Someone else already said it, users need to go through cycles when using steroids for best effect. During the times when the user is off steroids, their muscle mass atrophies. It's a mental thing to want to get back to the size that they attained and even larger. If you completely get off steroids, you shrink in size. Your strength goes down. You can't lift what you used to. If you measure your arms or chest, your numbers go down. It's tough for someone who used to be bodybuilder huge, and proud of it, to going down to looking above average.
