Running .5mg letro is going to be hard to measure if your tabs are 2.5mg. 1/4 tab would be .75mg and I would start lower, like .75mg EOD at most. See how you do and add more if needed. Outside of that, the cycle looks ok to me. 3 wks on the cut mix really is not that long. Maybe extend that part of the cycle to 4 wks. Outside of that, this looks good to me
