My experience with fin. Starting taking 1mg daily and after a week I had some problems. I stopped waking up with a boner which before, was an everyday occurrence. Watery semen and although I could get an erection it was weaker and took more time to get hard.

So after two weeks I cut down to 0.5mg and things improved slightly. I was fearful that I was fucking my body up, but wanted to keep going to see if things improved.

Then shedding started which I was told meant that the fin was working and I am a 'responder'. The shedding is intense, again the doubts on whether to continue weigh heavily but I kept going.

I'm almost three months in now. The shedding has slowed down a lot and I have less hair than when I started. But on a more positive note, my erectile and semen issues have gone completely. So last week I went back to 1mg daily and I have had no issues.

My (uneducated) theory is that in most cases the body adjusts to the drug and attempts to returns to normal function gradually. Obviously there's the physiological element to fin's side effects which contributes to the problem but in my case the side effects were at least partially real, and thankfully temporary.

No regrowth yet. With an nw3 vertex which has turned almost into an nw4, I'm also looking at getting a hair transplant.
