the graph was to give you an idea. i'll figure out the 100ed vs 200mg eod. like the graph shows on the eod inj. the blood level will drop then go back up( not what you want) with the ed the levels increase and don't drop. this will be the same with 100mg ed or 200mg eod, it might be the same mg in aweek but 100mg ed will give you a steady increase. with 200mg eod it will drop on the days you dont inj.
