Nolvadex is very comparable to Clomid, behaves in the same manner in all tissues, and is a mixed estrogen agonist/antagonist of the same type as Clomid.The two molecules are also very similar in structure.


It is not correct that Nolvadex reduces levels of estrogen: rather, it
blocks estrogen from estrogen receptors and, in those tissues where it
is an antagonist, causes the receptor to do nothing.The claim that Nolvadex reduces gains should not be taken too seriously. The fact is that any number of bodybuilders have made excellent gains while using Nolvadex.
