200mg is pretty high for a clinic to prescribe to a first timer, typically 80mg to 120mb/week is what clinic will start at and work its way up. So at 1500 I am guessing they reduce your weekly dosage?
I am brand new to TRT as well, I am prescribed 80mg/week to start. From everything I read and people I’ve talked to, thats sounds like a good place to start. Good luck.
