Clomid and Nolva actions
Clomiphene works by blocking estrogen at the pituitary. The pituitary sees less estrogen, and makes more LH. More LH means that the Leydig cells in the testes make more testosterone....That right there is the difference. Doing this helps your testes come alive....Nolvadex stimulates the biosynthesis of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) that in turn initiate both intra-gonadal testosterone production and spermatogenesis as well as systemic testosterone secretion and virilization. The blood flow brings GnRH into the anterior pituitary where endocrine cells synthesize and produce FSH and LH. Nolvadex helps with LH(needed for natural testosterone) and FSH(helps produce sperm) in the pituitary but doesn't block estrogen from the pituitary--it blocks estrogen in your chest with the breast tissue.
