If you don't come off after your cycle, you are effectively still cycling, as far as your recovery is concerned. You need to be off all steroids in order to start recovering. The longer you are on, the harder you will be shut down. So you either have to bite the bullet, come off and do a PCT. Or prepare to use test replacement for the rest of your life. I would suggest that if you are young, that you think this one through. In the long run, do you want kids at some point? Do you mind being tethered to a drug? If you are in your 30’s and have a family, it might be less of a concern. This is a question you have to answer for yourself.
