Consider this Nautica - The point of the two week cycles is that you are on half as much time as you are not using steroids.
If you had been running longer cycles before, then I imagine you did it something like this:
"On" weeks 1-10
"Off" weeks 11-30
I imagine that "if", in that 20 week period without androgens, you were able to maintain your 260 pounds at say, X bodyfat, then there is no reason you would not be able to maintain this weight with 4 smaller cycles spread out over the 30 weeks. You claim, instead, that you lost around 30 pounds of muscle. How were you able to maintain that 30 pounds during the looong off weeks of your previous cycling method, but not on the 2on/4off method? I think it would be best to look at what cycles you ran before hand to get you to 260, then see what cycles you ran that supposedly caused you to lose 30 pounds of muscle. I am not at all saying it is impossible, I would just like to look at all the factors involved. Thanks!
