The Effect of Simvastatin on Plasma Steroid Hormone Levels in Metformin-Treated Women with Non-Classic Congenital Adrenal Hyperplasia

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 user received hormone test results showing normal estradiol and testosterone levels, low SHBG, and normal free androgen index. They are considering starting finasteride but are concerned due to being slightly overweight.

Combining dutasteride and an aromatase inhibitor may increase testosterone levels significantly, potentially enhancing athletic performance but also posing health risks like elevated blood pressure and worsened cholesterol. The user is experimenting with dutasteride, anastrozole, minoxidil, and ketoconazole shampoo to manage hair loss and estradiol levels, while monitoring side effects and hormone levels.

Some users have experienced good hair regrowth with estradiol, cyproterone acetate, spironolactone, and bicalutamide, but these treatments may cause feminization and other side effects. It's advised to consult a doctor before using these treatments, as they can lower testosterone and have significant risks.

Finasteride has no effect on the user's estradiol levels, and body fat may influence aromatization. The user is on testosterone replacement therapy and uses everyday injections to manage high RBC count, with plans to measure DHT, DHEA-S, and pregnenolone levels.

A 30-year-old man experienced significant hair regrowth and improved libido after using finasteride and dutasteride for androgenetic alopecia, with no adverse effects. He plans to reduce dutasteride dosage when trying to conceive and has been using topical minoxidil since 2015.
