The main goal of PCT is to recover your natural test. If you are on an HRT program, you will not need to do PCT. When the cycle is complete, you will just go back to your normal HRT dose. I would urge you to get your labs done about 4 times a year, to make sure that your lipids, kidney and liver liver are all healthy. Recovering from a cycle isn't just about natural test recovery(for guys not on HRT). It's about letting everything heal up.  So just because you don't need to worry about recovering natural test, doesn't mean there aren't other factors in your body that need to normalize. Keep up on the labs and you can run cycles, then HRT with no issue
