I'll gladly swim upstream on this one, but consider yourselves warned. I have strong views on this subject.
You can't even begin to hope to maintain consistent levels of dbol, so that point goes right out the window. It's my belief that your stable hormone levels (whether or not you want them COMPLETELY stable is a whole other debate) should come from your injectables. Your orals would best be served to fuel workouts and the recovery process during the hours after said workout, especially if you're a powerlifter or other strength athlete. If you're taking orals for looks, I've got nothing for ya.
You can extend the duration of which you can safely run a given oral, and increase the preworkout dosage, by taking preworkout only on workout days only. Don't feel like you're reaping the benefits of increased protein/nitrogen synthesis? Then bump your test up. But using an oral for "consistent" increases in protein/nitrogen synthesis is like trying to drive a semi-truck cross-country with a gas tank the size of a 5-hour-energy.
As with everything else (when I'm not in a heated debate and have lost sight of temperance) I say experiment and see for yourself. You don't have to agree with me, but don't knock it unless you've tried it and didn't like it. So instead of taking 40mg per day, every day, in 4 even doses throughout the day, try 60mg preworkout on workout days only, and see if you don't have some great workouts. After all, recovery is great, but you have to have something to recover from and a killer workout is better than a marginal workout.
