Your natural test production will shut down within a few weeks. Of course it will eventually rebound, but you could be talking about months... losing all your gains, feeling like garbage, having no sex drive...

I don't understand what you are looking for to "make an informed decision"... you are already injecting yourself with a drug, why are you hesitant to take other drugs known and proven to aid in the recovery of your natural test?
Not to mention they are cheap, it would seem to be the easiest decision in the world to me.
