Can I take finasteride every other day to avoid a decrease in libido?

Hello, I am taking finasteride to counter hair loss. We are talking about a 5 mg pill cut in 4, so about 1.25 mg per day. For a while now, I've been taking 1.25 mg every other day to avoid any problem of low libido. This decision was motivated by a YouTube video from 2 Australian doctors who specialize in hair loss. They mentioned that taking 1.25 mg every other day had no negative side effects, as the concentration level in the body remained high enough to accomplish the task of inhibiting the testosterone molecule that causes hair loss.
