Nothing to do with shut down level. Once on TRT, any dose completely shuts you down.
Acne leveled to prior dose. It never went to pre TRT.
I believe both of us are taking (especially your dose) more than we ever produced naturally, even in our teenage hormonal peaks. For me, even during those times, I had zero acne, none at all. Now at 33 I am breaking out. I simply have more test than I ever had. I am considering dropping down to 84mg/week.
