What do you mean by completely shut down? Is your T level like 10?
The standard is 200 mgs every two weeks, but that leaves you flat after day 10 or so. I was using 200 mgs a week but found my libido was better (which is all that matters) at 100 mgs every 5 days. That also brought my T to just over 800, which is right where I want it. If your testicles are totally atrophied, you may need more. And you may want to do some HCG to get the boys back in town first. Then, when it starts to wear off, (you no longer have morning wood), start the HRT.
