Tamoxifen Citrate – SERM for Breast Cancer Research & Treatment
Tamoxifen is a first‑generation selective estrogen receptor modulator (SERM) that acts as an antagonist in breast tissue while exhibiting partial agonist activity in other tissues like bone and uterus. It competitively binds to estrogen receptors, blocking estrogen‑driven growth of breast cancer cells. Tamoxifen is clinically indicated for the treatment of estrogen receptor‑positive (ER+) breast cancer in both premenopausal and postmenopausal women, as well as for metastatic breast cancer and reduction of breast cancer risk in high‑risk individuals. Standard dosing is 20 mg daily, typically for 5–10 years as adjuvant therapy. Buy Tamoxifen Citrate online!!
