Letrozole

Powerful non-steroidal aromatase inhibitor for estrogen suppression research.

Letrozole is a non-steroidal aromatase inhibitor that competitively binds the cytochrome P450 aromatase heme group, sharply reducing estrogen (estradiol and estrone) synthesis. A single 2.5 mg tablet provides pronounced, long-lasting estrogen suppression. Used in oncology adjuvant therapy research and in endocrine studies investigating aromatization during anabolic protocols and post-cycle recovery. Pack of 50 tablets. Not for unsupervised use — consult a qualified specialist for any off-label research context.
