Toremifene citrate is an oral selective estrogen receptor modulator
(SERM) which helps oppose the actions of estrogen in the body.
Licensed in the United States under the brand name Fareston,
toremifene citrate is FDA-approved for use in advanced (metastatic)
breast cancer. It is also being evaluated for prevention of
prostate cancer under the brand name Acapodene.
It has already been covered that Toremifene is a SERM, and serves
to block Estrogen at various receptor sites in certain tissues
within the body (breast tissue in particular). As a layman
explanation, Toremifene pretends to be a 'fake' Estrogen that
occupies Estrogen receptors within breast tissue. With these
receptors occupied by Toremifene, real Estrogen cannot perform
their jobs there.
Toremifene does not reduce total blood plasma levels of Estrogen.
In addition to being antagonistic to Estrogen receptors in breast
tissue, it is also antagonistic to Estrogen at the hypothalamus
gland (this essentially 'tricks' the hypothalamus into thinking
there is little or no circulating Estrogen levels in the body,
causing it to increase its manufacture of Testosterone so that it
can utilize aromatization to restore these levels.
Toremifene is also agonistic to Estrogen receptors in other tissues
in the body (within the liver in particular). This means that
whileToremifene will act as an anti-estrogen in breast tissue and
the hypothalamus, it will act as an Estrogen within the liver. This
can have beneficial impacts especially during an anabolic steroid
cycle, such as improving and shifting cholesterol levels into a
more favorable range.
Originally developed to fight breast cancer, bodybuilders have used
Fareston to successfully fight gynocomastia caused when
testosterone converts to estrogen in the body and men grow breasts.
This substance can be used for little else and other similar
compounds, such as Nolvadex or Clomid, are much more effective in
It is also being evaluated for prevention of prostate cancer under
the brand name Acapodene.Used for Metastatic breast cancer in
postmenopausal women.PO 60 mg once daily with or without food.
