You wouldn't need much at all to power it. You are still in range so I dont see an issue honestly. If you want it lower you could start off with about 10mg EOD and then retest after a few weeks to see where you are
Your E isnt too bad so I would err on the side of caution. I would prolly go 1/4 ml 2x a week (assuming 25mg/ml)and see what labs tell ya next time around..
