About each compound
About Anastrozole
Anastrozole is an FDA-approved aromatase inhibitor used in TRT protocols to manage estradiol levels that become elevated during testosterone therapy. By blocking aromatase enzyme activity, it prevents excess conversion of testosterone to estradiol, mitigating estrogenic side effects such as gynecomastia and water retention. It is one of the most commonly prescribed ancillary medications in men's health and hormone optimization.
About Progesterone
Bioidentical progesterone is FDA-approved for use in women and is a key component of female hormone replacement therapy, balancing estrogen's proliferative effects on the uterus and breast. It also has calming, sleep-promoting, and neuroprotective properties via its neurosteroid metabolite allopregnanolone. In optimization medicine it is used in both women and some men for hormonal balance and sleep improvement. Oral micronized progesterone (Prometrium) is the gold standard.
