Me and a gym buddy of mine were discussing this yesterday, maybe you guys can help us out.

I was just thinking, if you body only naturaly creates roughly 10-15lbs of new muscle per year if your training and eating like a mad man, how can you hope to hold onto 30-40lbs of new muscle in a year (for a newbie)? I know it can be done because you see it all the time but is there anything else to it besides keeping your diet and training up while off cycle and having good pct?

Does gear that hardens and densifies (if thats a real word) muscle have any effect on helping you to keep your gains? Things like winny, anavar , masteron , eq, etc.
ie: After two large bulking cycle would it be smart to use some of these agents along with a low dose of test to help solidify gains before going into a large cycle again?

I ask because I think I'm one of the few ppl that has a set goal as to what weight and size I want to be before I stop, once I get there I'll come off gear and maintain natty as well as I can, but will I be able to in the long term...
