The system that has worked for me time and time again is. 500iu HCG eod during... Nolva 20mg daily during... stop both at end of cycle... Then 3 weeks after last Test shot... Start 300mg Clomid day 1 then 100mg for 10 then 50 for 10... Nolva 20mg daily the entire time running Clomid.. The first week and a half HCG 500iu eod starting the same day I start the Clomid.. Thats what works well for me never had any problem...
