I started fin before HRT and it caused some gonad pain of a few weeks. I had major depression and suicidal ideation prior to fin and HRT so I do not think it fueled any additional depression. I went on a SSRI just prior to coming out and stopped after GCS. I just did not need the SSRI's anymore.
I was on fin for years and stopped just before coming out. My depression was spiking and I did not need any potential increased depression from fin. At that time I stopped fin I did not have any detectable T in my system for I guess a year and before that it was 20 to 30 NG/DL.
I did not notice any increase in depression from fin. HRT, fin and minoxidil stopped and helped to reverse some MPB. I had 2 sessions of hair grafts ( 6000 grafts) which has made a huge difference in my life.
Fin (dutasterid is better), minoxidil and HRT are the best resources to combat MPB. I am just on E presently and have no way to make T. My hair is pretty good and getting better as the grafts get longer
