Nolvadex – Understanding Tamoxifen
Nolvadex (Tamoxifen) is a Selective Estrogen Receptor Modulator (SERM) in the subclass of Anti-Estrogen. Like Clomid many incorrectly assume that Nolvadex will lower the estrogen in the blood when in reality only Aromatase Inhibitors such as Aromasin (Exemestane) and Arimidex (Anastrozole) do that by eliminating the production of Estrogen. Nolvadex binds to estrogen receptor sites so estrogen can not bind and render it ineffective. It basically acts as a fake estrogen to block real estrogen specifically at the breast tissue. Nolvadex is used as an breast cancer treatment in females and as such it is highly regarded by steroid users for the anti estrogen capabilities to prevent gynecomastia or the development of breast tissues.
Prevention of gynecomastia is the primary purpose of Nolvadex as it will not block estrogen at other areas only at the breast tissue. It is highly regarded as there are very few side effects in body builders. While Nolvadex does up regulate Progesterone in females it does not do that in males. For Gynecomastia many men will take 10-30 mg a day with 20 mg being most common. Higher dose of Nolvadex does not make the item work faster or stronger so there is no reason for higher doses. In Post Cycle Therapy (PCT) after a steroid cycle, Nolvadex can help increase stimulating the brain to signal an increase in the production of FSH and LH which in turn increases testosterone production. It is reported that individuals in PCT are taking 20-40 mg per day for 4-6 weeks and often combine this with Aromasin or HCG or both during PCT. As Nolvadex will not counter act the suppression of testosterone production during cycle there is no reason to use nolvadex during cycle.
