Description: Femara is a new drug developed for the treatment of advanced breast cancer in women. Femara is the second in a new class of third-generation selective oral aromatase inhibitors. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen. Since many forms of breast cancer cells are stimulated by estrogen, it is hoped that by reducing amounts of estrogen in the body the progression of such a disease can be halted. This is the basic premise behind Nol vadex, except this drug blocks the action and not production of estrogen. The effects of Femara can be quite dramatic to say the least. A daily dose of one tablet (2.5 mg) can produce estrogen suppression greater than 80 % in treated patients. With the powerful effect this drug has on hormone levels, it is only to be used (clinically) by post-menopausal women whose disease has progressed following treatment with Nolvadex. Side effects like hot flushes and hair thinning can be present, and would no doubt be much more severe in pre-menopausal patients. When used with strong, readily aromatizing androgens such as Di anabol or test osterone, gynecomastia and water retention can be effectively blocked. In combination with Propecia (finasteride), we have a great advance. With the one drug halting estrogen conversion and the other blocking 5-alpha reduction (testosterone, methyltestosterone and Halotestin only), related side effects can be effectively minimized. Here the strong androgen testosterone could theoretically provide incredible muscular growth, while at the same time being as tolerable as nan drolone. Additionally the quality of the muscle should be greater, the athlete appearing harder and much more defined without holding excess water. Applications: Letr oz ole is intended for use only by women who are no longer of childbearing age. Possible candidates must have already ceased to menstruate. It is often used in patients who have already undergone other cancer treatments, such as radiation, chemotherapy, and used other cancer drugs, like tamoxifen. This nonsteroidal aromatase inhibitor may help prevent any remaining cancer cells from spreading. Femara is used for the treatment of post-menopause breast cancer. Femara is a powerful Aromatase Inhibitor that was developed to fight breast cancer. For athletes and bodybuilders, it is a drug used to combat the estrogenic side effects of anabolic steroids water-retention, acne and gynocomastia. It will also raise testosterone levels because of the lowered estrogen in the body. Side effects from include a lowered sex drive and continuous use can lead to lowered lipid function and an impaired immune system. Packing: Discreet packing ways as your requirement, 100% go through.
