Fulvestrant is a potent selective receptor antagonist estrogenic. Manifests its action in the body, not stop production of estrogen, but by preventing it to show their properties. It does this by binding to estrogen receptors in a competitive manner, making them unavailable for estrogen circulating in the blood pool. This kind of action makes it very similar to Nolvadex and Clomid, except that fulvestrant has no agonist properties mixed / atagoniste. It is a pure estrogen receptor antagonist. This preparation is the first antagonist injection type, which attracted the bodybuilders and athletes. Although not widely used, can successfully eliminate adverse effects caused by estrogen, in a course of anabolic steroids and androgens. These side effects are gynecomastia, increased fat and water accumulation in tissues.
Faslodex is a potent antiestrogen, much stronger than Nolvadex and Clomid. Although the targets are receptors for estrogen in the body can create very low estrogen environment, comparable aromatization inhibitors. In one study has shown that it is as effective in fighting breast cancer as Arimidex.
Fulvestrant does not pass into the brain, so lower side effects neural. These effects are hot flushes, mood swings and low energy.
Faslodex has been on the market in 2002, selling in many countries. It comes packaged in pre-filled syringes with a concentration of 50 mg / ml fulvestrant or a 5 ml syringe or two of each 2.5 ml each. The product is kept chilled.
The most common side effects of fulvestrant are met in gastrointestinal disorders such as nausea, vomiting, constipation, abdominal pain and diarrhea. Other common side effects are headache, backache, and sore throat. Side effects are rarely met irritation, weakness, urinary tract irritation, muscle pain, increased liver enzymes. It can also occur at the injection site irritation. Administration by athletes in order to reduce the estrogenic effects of steroids can increase the risk of cardiovascular disease by blocking the beneficial effects that estrogen has on the good cholesterol.
Administration is by intramuscular injection, the dose of 250 mg per month or one-inejctions 5 ml, or two 2.5-ml. Reduced administration (once, maximum twice a month for a 2.5 ml syringe) is an advantage of this antiestrogen.
It is an extremely expensive, less likely to find on the black market.
