Take the hcg during the cycle and no more than 2 weeks at a time. If you take HCG to long or to much, your testes wont be as sensitive to LH. This is bad. I would take 500ius ED for 2 weeks with arimidex or nolvdex mid cycle and for the last 2 weeks. Dont take it with clomid as clomid will be useless. Keep the arimidex going straight through clomid.
