Comparison of Finasteride (Proscar) and Serenoa Repens (Permixon) in the Inhibition of 5-Alpha Reductase in Healthy Male Volunteers

Saw palmetto, a 5-alpha reductase inhibitor, caused unexpected side effects like breast changes and altered semen consistency, which resolved after stopping its use. Concerns about similar side effects with finasteride or dutasteride were expressed, and another user reported low libido and depression from saw palmetto.

The conversation is about determining which type of Saw Palmetto, either Chamaerops humilis or Serenoa repens, is effective for inhibiting the 5 alpha reductase enzyme related to hair loss. Specific treatments mentioned are Minoxidil, finasteride, and RU58841.

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 experienced anxiety and side effects from topical finasteride and is considering switching to saw palmetto. Another user reported no improvement with saw palmetto and experienced liver issues.

The conversation discusses using topical serenoa oil, a natural anti-DHT treatment, for hair loss. It is considered less effective than finasteride and dutasteride but can be added to a routine with topical minoxidil.

Finasteride is the most effective treatment for reducing DHT and addressing hair loss compared to fish oil and saw palmetto. Topical treatments like RU58841 and minoxidil are also discussed, but finasteride remains the most effective option.
