I see people running test for 14+ weeks with orals mixed in at the front and back and it seems to be the norm. I understand that this is because test takes time to kick in.

But that is still 14 weeks of being "on" and shut down. Is a 10 week oral cycle that much worse? And no I don't mean 10 weeks of methylated compounds. Something like 5 weeks of ultradrol into 5 weeks of trenavar for example. Can someone explain exactly why this is not a good idea?
