Tamoxifen is a selective estrogen receptor modulator (SERM) that works by binding to estrogen receptors in certain tissues, particularly breast tissue, thereby blocking the effects of estrogen. This anti-estrogenic action makes it highly effective in treating and preventing estrogen receptor-positive breast cancer in both premenopausal and postmenopausal women. In bodybuilding and athletic contexts, Tamoxifen is commonly used during and after anabolic steroid cycles to prevent and treat gynecomastia (development of breast tissue in men) and to help restore natural testosterone production during post-cycle therapy (PCT).

Post-Cycle Therapy (PCT):

Week 1–2: 40 mg per day

Week 3–4: 20 mg per day

Gynecomastia Prevention: 10–20 mg per day, depending on individual needs.

Cycle Length: typically 4–6 weeks for PCT or as needed for gynecomastia treatment.

Tamoxifen is typically taken orally in tablet form. The dosage and duration of use depend on the purpose of the treatment. For preventing and treating gynecomastia or during post-cycle therapy, a common dosage is 10 to 40 mg per day, depending on the severity of the condition and the user's response. For breast cancer treatment, the dosage is usually higher, often around 20 to 40 mg per day, as prescribed by a healthcare provider.

It is important to take Tamoxifen exactly as prescribed by a healthcare professional and not to exceed the recommended dosage. Regular follow-up appointments and monitoring are essential to ensure the safe and effective use of Tamoxifen.

While Tamoxifen is generally well-tolerated, some users may experience side effects:

Hot Flashes: hot flashes are a common side effect of Tamoxifen, particularly in women undergoing breast cancer treatment. These are typically mild and may subside over time.

Nausea and Gastrointestinal Discomfort: some users may experience nausea, vomiting, or gastrointestinal discomfort while using Tamoxifen. These symptoms are usually mild and can be managed with dietary adjustments.

Visual Disturbances: Tamoxifen can cause visual disturbances, including blurred vision and cataracts, particularly with long-term use. Regular eye exams are recommended for those on extended Tamoxifen therapy.

Risk of Blood Clots: Tamoxifen can increase the risk of blood clots, particularly in the legs (deep vein thrombosis) or lungs (pulmonary embolism). It is important to be aware of the symptoms of blood clots and seek medical attention if they occur.

Mood Swings and Depression: some users may experience mood swings, depression, or changes in mood while taking Tamoxifen. These side effects are usually temporary but should be monitored closely.
