There are a lot of factors involved with staying on. It depends on a lot of different things if you decide to go that route. To be honest, it is actually easier on your body to stay on a maint dose than cycling on and off, but you must remember that the longer you stay on the harder it is to recover and get back to your body's natural levels, but not everyone is concerned with getting their natural test levels back up to par. If you are not competing and you are planning on having kids, its not the best idea, even though if you do everything right, reproducing should still not be an issue, but why risk it if it is something you feel is important, the chance is there. If you have already popped out all the kids you want and you are a little older, than it is actually healthier for you to stay on a maint dose than taking off 8 - 10 weeks and getting back on. Those that do stay on year round, most of them anyway, still run HCG throughout to keep things kicking. Like I said though, there are a lot of factors involved and staying on shouldnt be something you just jump into, you should definately put some thought behind it and make sure it is something that you definately want to get yourself into.
