Dont get greedy or you will experience the rule of diminishing returns...you have made good gains and although being on is fun! and feels great! Your gains will eventually dwindle down to nothing no matter how much gear your on. The longer your on the longer it is to come back and the less gains you keep so sure you could stay on and gain 40lbs but when you come off you will loose the majority of what you have gained.

My advice run your stuff for 12 weeks, do proper pct, go back on in 12-16 weeks or when your body is ready.
