mdl is microdose Lupron. It is used to suppress you somewhat, but is used with poor responders instead of long Lupron. It is often used alone, as is estrogen priming (which are the patches you described). They are not often used together, but Dr. Davis at Cornell has some protocols where they are used together (or he did anyway). I used his protocol. Erin on this board posted the exact protocol specifics at one point (maybe on the over 40 board), but I'm not sure how to find the post.
