Christ… 200mg a week? Have you had your DHT checked? T converts to DHT and hence your hair loss.
I have a picture of me when I was on 150mg a week and you can see my scalp through my hair and I don’t have male pattern baldness.
Like the others, I don’t recommend an alpha 5 reductase inhibitor. Instead lower your T dosage to 75mg a week and watch your hair fill out nicely.
