I’ve dieted for shows like you described, have done that for twenty years. My body responded to things that were opposites of what is supposed to be. I must say it was tough and I believe AAS can provide help when diet and training isn’t perfect. I’ve had a career that I would do 4 x 14 hours from 1830 to 0700 plus travel. On my feet a ton, sitting but never being able to eat 5 meals on a shift. I would have to sneak and eat in the restroom or go on a “smoke break” I also did the dreaded carbs before bed. The worst thing you can do with overnights is on off days try to switch schedule. I think anything done with dedication and consistency will work. I did better when I was instinctively getting food in. I pretty much would have my macros in order, and that’s it. But that’s genetics, training like it’s your last day and whatever. Did some years I get to do double splits and sleep and eat in between with no “work” ? Yep. Unfortunately, at that TIME the access to supplements were sketchy. What would I prefer? More access to better supplements. That’s my honest assessment if I was competing.
