Pulsing in general is the worst idea i think DR.D ever came up with. He is very knowledgeable and has helped me out quit a bit when i first joined so i'm not knocking him, just his pulse protocol. This idea i highly disagree with as do many others. I never had any gyno issues nor am i prone to it. Did my first pulse a few yrs back. After a month i had rebound estrogen and noticed a lump that hurt like hell under my nipple. Thank god i had letro on hand. if your trying to avoid shutdown then don't run a cycle if you don't care then run the cycle straight through none of this pulse bull****. run a good pct 50, 50, 25 ,25 of clomid is perfect to get you back to normal.
