Potency of a Novel Saw Palmetto Ethanol Extract, SPET-085, for Inhibition of 5α-Reductase II

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.

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.

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.

Saw palmetto, particularly the standardized extract with 85% fatty acids, is discussed as a potential hair loss treatment, but opinions on its effectiveness vary. Some users combine it with other treatments like finasteride, minoxidil, and ketoconazole, noting mixed results in hair retention and shedding reduction.

Topical saw palmetto is discussed as a mild anti-androgen for hair growth, with some users combining it with other treatments like spironolactone and ketoconazole shampoo. Users share mixed experiences, with some not noticing regrowth and others hopeful for positive results.
