It looks to me that you just spent the last 30 minutes on Wiki looking up anabolic steroids.
What you lack is empirical evidence working directly with alpha males who are natural and those who are dirty. No amount of internet research will take the place of empirical evidence.
Strength gains, for the lucky few (generally young, strong males), CAN be maintained if one is smart about it. And even if there is a small reduction in said strength gains, the OVERALL performance can be buoyed up with other factors (such as being around other big leaguers, better living and traveling conditions, better coaching, etc.).
