this is kind of odd, but the answer depends on how long youve been at a certain size. Look at the post Big A made a week ago where he posted a pic saying he was only training once a week and just had a 3 month lay off. He's huge!
The question is why is he so huge still?
Well as Dante said a long time ago , setpoints.
The longer you maintain a certain size the longer it takes for it to go away with or without drugs.
So how do you avoid the post cycle crash? Well thats simple, not easy but simple.
Get as massive as you can naturally and hold that size for a long time. take AAS, get bigger and hold that for even longer. If you can find it there's a post where Dante gives a hint of insight on his views on dosing, he doesnt flat out say anything but if you read carefully he does give you a clue. You can hold a lot of size on a small HRT cruize dose, 100-150 mg/week if you try hard enough especially with the food part of it. and thanks to the access everyone now has to HGH and other peptides it's even easier to do.
Here's how I would do it.
Drop to an extremely low cruise dose or come off. I don't like PCT because your throwing more drugs at a problem caused by drugs in the first place. I've done PCT, havent done PCT, it didnt seem to matter either way.
Next you have to do somethign I don't normally reccommend. Force Feed. Eat WAY more, and on top of that you may need some cardio just to keep from getting fat. Reduce training volume, add more rest days, increase intensity to fight just to keep every possible pound you gained. Make sure the training is heavy short and frequent, I dont know, DC maybe?
There will be a slight crash but I think over 6-8 weeks you can hold onto almost 80% of your gains. This, ofcorse will also depend on how long you have maintained a certain size.
