Right now just started on 750mg a week. 2nd week. Still debating on whether or not to stay at 750 or go down to 500mg next week. Me, as i always have, i shoot it up all in one day. Sus has fast acting and long acting esters so it really doesn't matter if u do it once or twice a week. The buildup from the long acting esters will keep blood levels more stable. Now if it were just test propionate and that's it then yeah u need to do it every other day or every third day.
