well I am not so sure about this either, maybe 5 mg fin decreases serum DHT more than 1 mg but does not have a considerable effect on the scalp DHT? also 0.5 mg dutas decreases serum DHT by nearly 92% however it only decreases scalp DHT by 50% smth. I heard that 5 mg finas decreases scalp DHT by 38%.
so I was wondering, if I took 0.5 mg dut and 1 mg fin daily, can I decrease it more than 50%? or additional fin will not make a difference since dut is already stronger than fin?
PS: btw I am not looking to decrease my sex drive by 100% doing that

actually that's the only thing that keeps me away from doing it
