Some people get large gains done don't. I theorize those who don't get big gains from test are already at there genetic max and the test just isn't strong enough to takethem much over it. A test cycle will prob yeild around the same weight as a decent designer steroid such as epi will yeild, but the test will take longer but make you feel better and easier to keep gains.
The time off thing really opens up a can or worms. Not every one sticks to the time on time off rule but just cause some recover fine doesn't mean you will. When it comes to long steroid cycles I don't think the time off has to be even since staying off for four months is a long time. However with ph cycles since they are usually shorter I think the time on time of rule is good.
This whole topic only brings peoples opinons to the table and nothing more. Some are cool with only a month or two off otheres need more time. No way too tell till it's too late. Also you have to think about te moretime you spend on the longer time you spend with bad lipids, liver values ect; mainly for orals, the worst your long term health problems will be.
