Dutasteride vs Finasteride

[Shwareb]

Is it true that Fin 1mg ED inhibits 85-90% of 5AR2 (and 1% of 5AR1) whereas Dut 0,5mg ED inhibits 98-99% of 5AR2 (and 50% of 5AR1)? Since type 1 inhibition doesn’t prevent hair loss is that extra 8-14% suppression of 5AR2 really worth the 50 times greater suppression of 5AR1? By worth it I mean if it makes a huge difference in terms of regrowth/maintenance of hair. If so can the extra 8-14% suppression of 5AR2 really be the reason because some studies show that Dut produces far superior results?
