I lift 4 days a week 2on, 1off, 2on, 2off, hitting each muscle once a week directly.
Works great for me and what I plan to use most of the time, although I will do 3x a week fullbody from time to time and other ish. Never know what my trainings gonna be like. It's constantly evolving.
If I was on AAS, I'm guessing I'd workout 6on, 1off hitting each bodypart 2x a week and using a little more volume and intensity than I can handle naturally. That's best guess as I haven't used AAS, but even on 1-AD my recovery was faster than normal so I can only guess what it would be like on AAS.
