Don't worry about it man, 1mg of finasteride is nothing. It only lowers scalp DHT by around 30% and serum DHT by 70% which is hardly anything. I'm on 1mg of finasteride + .5mg dutasteride + 200mg of oral spironolactone + RU and I can still get erections but I'm still thinning.
A lot of the guys hating on...
