Is 2.5 mg of dut even worth it?

Recently started 0.5 mg yet now I’m seeing a bunch of posts claiming 2.5 mg is even better.

But most studies I’ve read show that there is a diminishing returns in hair counts increases in 2.5 mg despite there being way more suppression of scalp DHT.

Unless you have the most extreme hairloss (you went from NW1 to 4 in under a year) it seems like you either don’t need it, or you have another condition causing hair loss.
