I get the impression that we have some misunderstanding of 'shutdown' here.
You will stop producing endogenous testosterone and your nuts will atrophy while taking Eq and there's nothing that I'm aware of that you can do to avoid it. You run a PCT (post cycle therapy) after your cycle to get your natural systems up and running again.
Proviron will help with maintaining libido.
What do you mean when you say "shutdown"?
