Well, I'm not completely sold on N-dex taking the place of clomid, but here is what is said to be effective.
Week 1 to 10: cycle
Week 11 to 12: 500-1000IUS of HCG with 20mg of N-dex ED
Week 13: 20mg N-dex ed
Week 14 and 15: 10mg N-dex ED
I do everything above but during weeks 14 to 16, I would run a regular clomid cycle.
