Specifications
tamoxifen citrate is a serm that acts as both antagonist and agonist in relation to the estrogen hormone. it is an anti-estrogen in that it binds to estrogen receptors in certain parts of the body, particularly in the mammary tissue.
this action prevents estrogen from acting on its originally intended point of binding. this makes tamoxifen citrate valuable to breast cancer patients as breast cancer feeds off of estrogen. and it's valuable to steroid users as increased estrogen levels can bind to the mammary tissue and lead to gynecomastia.
