5 mg is obviously more, but the question is about the rate of dosing really. is twice a week at 2.5 going to be as or more effective than more frequent dosing with less.
I'm doing EOD..half life is long but always better more often than Bulk Dosing although your Bulk dose is too high...would be 1.5mg 2x per week...2.5mb is 5 days worth at standard dose.
