The most common version of formestane sold was in a topical gel form and it was dosed at 100-200mgs per application. Users would apply it onto clean, dry skin and rub in thoroughly; usually on the thighs or upper arms. It took 1 to 5 minutes to dry.
The injectable version for both breast cancer purposes and bodybuilders is 125mgs twice per week or 250mgs once per week.
How Does Formestane Works For Breast Cancer?
By significantly reducing estrogen levels in the blood, methanesulfon may exhibit antitumor activity. In a trial involving 147 postmenopausal women and advanced breast cancer drug resistance, 22% of patients received partial response and 20% achieved disease stabilization.
In comparing the non-steroidal aromatase inhibitor anastrozole with methotrexate, it was found that anastrozole was more effective and consistent in inhibiting estrogen levels in vivo. However, these results are unproven clinical significance.
Formestane is a second generation irreversible steroid aroma inhibitor. It inhibits the aromatase responsible for converting androgen into estrogen, thereby preventing estrogen production.
Breast cancer may be estrogen-sensitive or insensitive. Most breast cancers are estrogen-sensitive. Estrogen-sensitive breast cancer cells are dependent on estrogenic activity.
Therefore, removal of estrogen from the body can become an effective treatment for hormone-sensitive breast cancer. Formestane is specially designed for the treatment of postmenopausal women.
Unlike premenopausal women who produce the most estrogen in the ovaries, postmenopausal women produce most estrogens in peripheral tissues with the help of aromatases.
The aromatic compound inhibitor Formestane can help reduce the local production of estrogen by blocking peripheral tissue (ie, aromatase in breast tissue) to treat hormone-sensitive breast cancer.

Treatment of Breast Cancer:
Because of its potent estrogen-suppressing action, formestanes has been used clinically to treat breast cancer patients in a number of countries including England, Germany, Switzerland, Spain, Australia, New Zealand, Italy, and Malaysia. It has been shown to be an effective option as a second line of defense after , an estrogen receptor antagonist, has failed to elicit a positive response with patients, and produces an overall response statistically similar to when administered as the first-line therapy. In terms of overall potency, formestanes is not as strong as the selective third generation inhibitors like Arimidex () or Femara ().
Use for Bodybuilding:
Formestane can lower SHBG up to 34%, which will increase free levels. SHBG (sex hormone binding globulin) is a protein that binds to sex steroids, and renders them inactive, for as long as SHBG is bound to them. There is a difference between 'free' , and 'bound' . Free testosterone is what matters, so lowering SHBG will increase 'free' testosterone. Higher means more strength, muscle mass, less body fat, better sense of well being, and libido.
