There are obviously a lot of factors involved when estimating your 2nd cycle gains, like steroids used, training experience, diet etc. Assuming you have a good cycle lined up and you eat like a horse you should be able to put on a stone.

With regard to time on/time off I play it very safe. If I run a 12-14 week cycle I usually take off 4-6 months. The traditional formula is time off = time on.
