One of the Medistar Steroids in Canada, also known as Tamoxifen.
Nolvadex is very comparable to Clomid, it behaves in the same manner in all tissues, and is a mixed estrogen agonist/antagonist of the same type. 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 has made excellent gains while using Nolvadex.
However, if this effect exists at all, it must be very minor, due to the excellent gains that many have made, and from the fact that no one has noticed any such thing from Clomid which has the same activity profile.
The fact that Nolvadex will reduce water retention may result in the user agreeing that gains are less, since weight gain is less, thus reinforcing the bias. It has a half-life of 4-5days. It may cause nausea, bone pain, muscle pain, flushing, and change in the Menstrual Cycle, etc.
