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 HCG
Human chorionic gonadotropin (HCG) is an LH-mimicking hormone used in TRT to maintain testicular function, prevent atrophy, and preserve fertility during exogenous testosterone therapy. It is also used in male hypogonadism as a monotherapy to stimulate endogenous testosterone production. Compounded HCG remains available after FDA discontinued most branded injectable formulations. It is an essential component of fertility-preserving TRT protocols.
