description:
1 . this product is most often referred to as "nolvadex" by bodybuilders. nolvadex is not a steroid, rather
a selective estrogen blocker. while nolvadex doesn't prevent the buildup of estrogen in the body, it does
prevent it from acting on certain receptors, most notably, those located in the nipples. this has obvious
benefits to bodybuilders, because this is the area in which "gyno" occurs during the use of aromatizing
steroids such as testosterone.
2 . nolvadex (tamoxifen citrate) 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.
3 . the belief that it reduces gains seems to stem from the fact that the scientific literature reports a slight
reduction in igf-1 (individuals using anabolic steroids were not studied though) from use of nolvadex.
thus, dan duchaine reported that it reduces igf-1 and therefore reduces gains. 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.,

applications:
1 . tamoxifen is an antagonist of the estrogen receptor in breast tissue via its active metabolite, 4-
hydroxytamoxifen. in other tissues such as the endometrium, it behaves as an agonist, and thus may be
characterized as a selective estrogen-receptor modulator. tamoxifen is the usual endocrine (anti-
estrogen) therapy for hormone receptor-positive breast cancer in pre-menopausal women, and is also a
standard in post-menopausal women although aromatase inhibitors are also frequently used in that
setting.
2 . tamoxifen is used to treat infertility in women with anovulatory disorders. a dose of 10–40 mg per day
is administered in days 3–7 of a woman's cycle.in addition, a rare condition occasionally treated with
tamoxifen is retroperitoneal fibrosis.
3 . tamoxifen is currently used for the treatment of both early and advanced er+ (estrogen receptor
positive) breast cancer in pre- and post-menopausal women.additionally, it is the most common hormone
treatment for male breast cancer.it is also approved by the fda for the prevention of breast cancer in
women at high risk of developing the disease.it has been further approved for the reduction of
contralateral (in the opposite breast) cancer.
4 . tamoxifen also increase the risk of adverse side effects. some cases of lower-limb lymphedema have
been associated with the use of tamoxifen, due to the blood clots and deep vein thrombosis (dvt) that
can be caused by this medication. resolution of the blood clots or dvt is needed before lymphedema
treatment can be initiated.
