Why Not 0.75mg Finasteride?

In the past, you have reccomended .5mg of propecia for those experiencing side effects. Why not .75mg?

As long as you have a good way to split a 1mg oval/circular pill into the correct geometry to make it 0.75mg, I don’t see a problem. Then you can take the 0.75 and save the 0.25 remaining for the next three days when you can combine three 0.25 to take the 0.75 dose. Or I guess you can just throw away the 0.25. Get the point? It makes practical sense to split a 1mg pill in half to make 0.5mg.
