This is interesting because I’ve thought the same. Theoretically it shouldn’t be true, but you’re right many guys on forums don’t seem to get sexual sides on dut as bad as fin.
I think that monty guy who took both remarked that fin was a lot worse for his libido than dut.
From what I’ve read dut users seem to perhaps encounter stronger brain fog issues, which isn’t surprising.
I wonder if , as some have suggested, the longer half life of dut seems to lessen the possibility of a crash. It seems silly to suggest fin is safer when dut blocks even more DHT but we haven’t seen a load of victims. Obviously that’s due in part to it not being licensed for hairloss but many are taking it.
