Bhasin's study is fundamentally flawed in that it sampled muscle size while they would still have inflated muscle size from increased glycogen and water retention from the steroid use and didn't use a method of measurement that compensates for it. It is not a direct comparison of contractile tissue, which is presumably what we would care about.

Belgian Blues grow that large because of a mutation with their myostatin gene. This is hardly the same method of action.

That study was on untrained subjects. Steroids increase your baseline musculature, but only to a point.

You're not going to accidentally an Arnold by injecting testosterone and sitting on the couch every day.

Your spell checker made wonder what ghosts are doing with steroids.
