From what I've read nolva and clomid bind to the estrogen receptors in the body with specificity to different areas and thereby don't allow estrogen to produce it's effects (simplified version). So this must mean that there will still be estrogen circulating in the blood correct? Given this, would it be beneficial to add in something that reduces circulating estrogen, such as an ATD based product (eg Novedex XT), or is this just overkill?
