The only down side I can see is ed or eod injections. Like everyone else said, faster recovery is the reason. The human body will repair itself no matter what, so as far as not doing as much damage I don't know.
Less results!
I've tried short cycles, and to me it seems just about the time things start to click your cycle is over.
Now I go 12 to 20 weeks, and life is gooood.
Well, as a female, that is about all I run. Can't do the 12+ week cycles or I will no longer be female. I would think a shorter cycle for a guy would equal less damage in the long run. Like with natural test and gyno issues. Also cheaper.
another favorite catch phrase of mine "clit weiner". In my book, if your into or even do a girl with a weinerish clit, then your gay, plain and simple.
