Quick Summary

Aromatase inhibitor — estrogen control for TRT and growth plate optimization

Also called: Arimidex, AI, Aromatase Inhibitor

What is Anastrozole?

Anastrozole is a potent, selective non-steroidal aromatase inhibitor (AI) that blocks the conversion of androgens to estrogens. Primarily prescribed for breast cancer treatment, it is used off-label in males for estrogen management during TRT, to maintain testosterone-to-estrogen ratios, and — controversially — by younger individuals seeking to delay growth plate closure and maximize height potential. Research indicates estrogen plays a key role in epiphyseal fusion; aromatase inhibition delays this process. Hero et al. (2005) and Wickman et al. (2001) documented increased predicted adult height in adolescent males treated with AIs.

How It's Made

Anastrozole is a synthetic triazole compound produced through chemical synthesis. Available as 1mg oral tablets.

Potential Benefits

Estrogen control during TRT
Potential height optimization in adolescents (controversial)
Improved testosterone-to-estrogen ratio
Reduced gynecomastia risk
Improved body composition (less water retention)
Studied in adolescent males for height augmentation
