there is no problem with running year round.
Blast and cruise,if the benefits outweigh the sides then go for it,example would be if you are not wanting children anymore,(you can still have kids its a small chance that sperm count will be lower) you have enough money to obtain enough compounds to last through out the year ect.
keep in mind that the longer your on the harder it is to come off.
how one would go about it is this, you run a heavy cycle of your choice, and then instead of doing PCT and coming off you simply run test by itself at a standard TRT dose for however long you will be "off" cycle. then when you plan and run the next cycle simply add in whatever compound you choose and run higher test. then repeat
I find this is much simpler than running PCT every time and trying to recover,when there is no logical need to recover.
