I do a form of microcycling, but not as strict as some. It's mainly strength for me with size building in between, but I'm going to size build this winter with a vengeance. Watch this space.

I think the best way, long term, to solidify gains is to treat your training as a long term venture. Build slowly, lose slowly. You have to expect to lose some size and strength short term along the way, whether you cycle AAS or not. With muscle memory and improved training and knowledge of training and diet and how you react to both you will get bigger and stay bigger as you age anyway (within reason obviously).
