I dont have the answer, but a long time ago I use to hear 1.5-2mg 2x week. Later it came out that the half life is only a couple hours and that it should be dosed 2 times a day in smaller doses to equal 3-4mg a week.
So be weary of the protocols people present to you, it's all over the place. Given the half life, daily would make the most sense to me but ultimately I am not positive
