im pretty sure .5mg e3d or 2x week is a normal dose schedule for prolactin control when on a 19-nor. Now if your catching it to late (not starting the 19-nor and antiP at same time) then I suppose a heavy dose is needed for correction? You won't notice a prolactin level of zero like a low E2 level and I can't find the papers right now but I know you don't want it bottomed out at 0 for too long. A dose of 2.5mg e3 weeks would put any health male at 0 for a long time even if you were running a g of TA a week...
