Anastrozole

Highly selective non-steroidal aromatase inhibitor — estrogen modulation research grade.

Anastrozole is a potent, selective aromatase inhibitor that blocks conversion of androgens (testosterone, androstenedione) into estrogens (estradiol, estrone). At 1 mg daily, circulating estradiol can drop by 70–80% within 1–2 weeks. It has no androgenic, estrogenic, or progestogenic activity. Used in oncology and endocrine research for estrogen-dependent pathways, and in sports-pharmacology research for aromatization control during anabolic cycles. Each pack contains 50 tablets at 1 mg. Prescription-grade compound — research and educational reference only.
