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.
A 29-year-old male on 1 mg Finasteride for 3 months has experienced a significant increase in testosterone and estradiol levels, with no major side effects except slightly oilier skin and increased emotional sensitivity. The user is concerned about these hormonal changes and seeks advice, as their general practitioner is not knowledgeable about the issue.
The user has been using finasteride and minoxidil for hair loss but experienced worsening temple recession. They suspect they might be more sensitive to testosterone and are considering trying RU58841 or CB 03 01 as additional treatments.
Finasteride can affect hormone levels within two weeks, and a break of several weeks is recommended for baseline results. Monitoring E2 and testosterone is suggested to assess the risk of gynecomastia.
The user got blood work to check hormone levels before starting Finasteride for hair loss and is seeking advice on interpreting the results. They are considering hormone levels in relation to potential side effects of Finasteride.
