I like to use Human Chorionic Gonadotropin (HCG) and nolvadex the last two weeks of a cycle, and then hit the clomid three days after the last Human Chorionic Gonadotropin (HCG) shot. Works the best for me, ive tried nolva only, clomid only, that combo works the best. I use 20mg of nolva ed when running the Human Chorionic Gonadotropin (HCG), becuase Human Chorionic Gonadotropin (HCG) makes some susceptible to gyno.
