Despite advancing to Phase II trials, safety concerns and financial struggles led Aventis to abandon its development. Proskelia, which later merged into ProStrakan, couldn't prioritize the drug, leading to its eventual stagnation and failure to reach the market.

Natural vitamins like pumpkin seed oil, saw palmetto, and ecklonia cava are discussed for their potential to lower DHT levels. They may work similarly to finasteride but are significantly weaker.

Pyrilutamide is considered by some as an alternative for those avoiding 5AR inhibitors like finasteride and dutasteride, but opinions on its effectiveness vary. Some users report similar results with fluridil and pyrilutamide, while others find pyrilutamide less effective compared to prescription treatments.

Alfatradiol is discussed as a weak 5ARI and estrogen, not as effective as minoxidil, RU58841, or CB-03-01, but a safe alternative for those who can't use finasteride. Users express frustration over the lack of strong FDA-approved topical antiandrogens for hair loss.

Kintor Pharmaceutical's Phase 2 results with the drug Pyrilutamide, a potential alternative to 5-ARI drugs like Finasteride and Dutasteride but without the side effects. It could be used in combination with other topical treatments such as Minoxidil. The safety of the drug has been demonstrated in 6 months of use, however there are still questions about long term efficacy and systemic absorption.

The conversation discusses GT20029, a new topical drug for hair loss and acne without notable side effects, which has been accepted for investigational use in China. Some users express skepticism about the legitimacy of the company and the potential for other drugs like RU58841 to be developed due to patent expiration and lack of profitability.

The post discusses a hair loss treatment regimen using saw palmetto, pumpkin seed oil extract, EGCG (green tea) extract, grape seed oil extract, rosemary oil extract, and Zix. The user plans to use these DHT-blockers and 5AR inhibitors for six months and report the results.

Ursolic acid, found in apple peels, lemongrass, rosemary, and lavender, may have anti-androgen effects similar to finasteride. It might be beneficial for hair health when used with other treatments like Minoxidil, Finasteride, and RU58841.

New treatments for AGA are emerging, including pyrilutumide, gt0029, scube3, kx-826, and pp405. Verteporfin is mentioned as a promising option.

Pyrilutamide and RU58841 are androgen receptor antagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.

The conversation discusses GT20029, a compound by Kintor Pharma that degrades androgen receptors and is in trials, with potential as a hair loss cure. Another promising treatment mentioned is an antibody that blocks prolactin and has shown positive results in macaques.

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

Hair loss treatments, specifically the use of Alfatradiol as an over-the-counter topical 5AR inhibitor that has been shown to be effective in stopping hair loss without side effects. Other treatments discussed include Minoxidil, finasteride and RU58841.

The conversation is about considering pyrilutamide 1% as an alternative treatment for hair loss due to intolerance to 5-alpha reductase inhibitors. Some users suggest it might be effective, while others view it as a temporary solution.

User experienced reduced hair loss with 15mg RU in Serioxyl but had concerning chest pain. Others suggested consulting a doctor or lowering the dose.

Users also mention using ketoconazole, minoxidil, and low-level laser therapy (LLLT) as part of their hair loss treatment regimens.

The drugs RU-58841, Pyrilutamide (KX-826), Apalutamide, Enzalutamide, and Darolutamide, which are nonsteroidal antiandrogens (NSAA), potentially impacting male fertility. Pyrilutamide, similar to Enzalutamide, may have reversible effects on fertility.

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.
