If you're going to taper down i would stay on a TRT dose. If not, there really isn't much of a point tapering down prolonging the inevitable of a PCT. When your PCT time frame starts just drop what you need to drop and PCT the shit out of your cycle. Unless you're going to maintain a TRT dose.
Personally I dont mind staying on long term. I'll cruise on a TRT dose for a bit. But im constantly getting bloods done.
