Inhibin A Is Downregulated During Chemotherapy in Patients With Breast Cancer

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

The conversation discusses concerns about starting topical finasteride due to high estradiol levels and the potential risk of gynecomastia. Suggestions include using ultrasensitive estradiol tests and considering aromatase inhibitors like zinc, ZMA, or DIM supplements.

Finasteride treatment is being considered, and it's advised to track DHT, testosterone, estradiol, and SHBG levels to monitor hormonal changes. These tests will help understand the treatment's impact.

A user discusses their hormone blood test results before starting finasteride for hair loss, noting high DHT and estradiol levels. They tried topical finasteride for a few days but felt tired.

A 22-year-old with high estradiol levels is considering starting finasteride for hair loss. They have an upcoming endocrinologist appointment to discuss whether they should proceed with the treatment.

A user has been taking finasteride 1mg for 10 years without side effects but is concerned about high estradiol levels affecting weight loss. Another user suggests using estradiol blockers under medical supervision to manage the levels.
