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 Testosterone Cypionate
A synthetic ester of testosterone, testosterone cypionate is an intramuscularly or subcutaneously administered androgen that provides sustained release of the hormone over approximately one to two weeks. It binds to androgen receptors throughout the body, promoting protein synthesis, muscle development, bone density maintenance, and secondary sex characteristics. The compound is primarily used in the treatment of male hypogonadism and as a component of gender-affirming hormone therapy.
