The conversation discusses a user experimenting with RU58841 for hair regrowth by ingesting it, which others find concerning. There are mentions of potential side effects and comparisons to other treatments like minoxidil, finasteride, and flutamide.

RU58841, an anti-androgenic compound, showed early promise for treating alopecia but faced challenges after its patent in 1997. 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.

The conversation discusses the effectiveness of RU58841 for hair loss compared to pyrilutamide, which failed to show significant hair regrowth in trials. Some users report personal side effects with RU58841 and question the criteria for success in hair loss treatments.

The conversation discusses the safety and trustworthiness of ordering RU58841 from Lyphar Biotech in China, with a focus on pricing and reliability. The user is seeking advice on whether to proceed with the purchase or consider alternative sources.

RU58841's potential side effects, particularly heart palpitations, are debated, with some attributing them to contamination with minoxidil. Users report mixed experiences, with some seeing no side effects and others cautioning about the lack of reliable data on RU58841's safety.

RU58841 caused severe side effects like heart palpitations and shortness of breath, leading the user to stop using it. Minoxidil and finasteride were effective without side effects, while RU58841's safety and effectiveness remain uncertain.

A 27-year-old male is experiencing a recurring pattern of hair loss after 5 months of using oral minoxidil and finasteride, despite initial success. He is considering using topical androgen receptor blockers like RU58841, pyrilutamide, or clascoterone to address potential androgen receptor hypersensitivity.

Clascoterone's European release is expected in Q4 2026, with FDA approval anticipated by mid-2027. The discussion includes questions about the approval timeline and potential acceleration due to unmet needs.

RU58841 is not recommended for use around children due to potential exposure risks. Alternatives like CB-03-01 might be considered, but further research is advised.

The conversation discusses whether RU58841, if FDA approved and safe, would be recommended over finasteride for hair loss. Specific treatments mentioned include RU58841, finasteride, and minoxidil.

The user plans to use RU58841 in the morning and Pyrilutamide in the evening for hair loss treatment, considering replacing Fluridil with Pyrilutamide. They believe Pyrilutamide is effective.

Clascoterone cream can be used on the scalp, but it may not be effective due to its dosage. AR antagonists like clascoterone are generally less effective than 5AR inhibitors for hair loss.

The conversation is about finding a reliable Chinese source for pyrilutamide or RU58841, ideally with a third-party Certificate of Analysis from Janoshik Analytical. The user is seeking recommendations for these hair loss treatments.

RU58841 is not FDA approved, and users are discussing its availability and legitimacy in India, with some mentioning brands like Vantanex and Capomil. One user warns about the risk of gyno from RU58841, advising to stop use at the first sign of sensitivity.

The conversation discusses using Minoxidil, finasteride, RU58841, and pyrilutamide for hair loss treatment. The user is considering adding a topical treatment and has not experienced side effects from current treatments.

The user discusses using Follics FR5, FR10, and FR15, which combine Minoxidil, Adenosine, Procapil, Azelaic acid, and Procyanidin B2, to address hair loss. They have previously used Minoxidil, Finasteride, and Dutasteride with varying success.

A 30-year-old man experienced significant hair loss after starting testosterone replacement therapy (TRT), which did not improve with daily finasteride and minoxidil. He is considering restarting TRT and is seeking advice on using pyrilutamide or RU58841 to prevent further hair loss.

The conversation is about using pyrilutamide and RU58841 as topical solutions to prevent hair loss. Pyrilutamide is considered safer but less potent than RU58841, which some users find effective despite potential side effects like heart palpitations.

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.

The user has been using Pyrilutamide (Pyril) for hair loss for a month alongside finasteride/dutasteride since 2021 but hasn't seen results. They are considering switching to RU58841 due to its many success stories, despite being skeptical about the legitimacy and testing of Pyrilutamide.

A user started using RU58841 for hair loss and experienced anxiety and physical discomfort. Other users suggested avoiding the treatment due to similar side effects and recommended alternative treatments like pyri.

RU58841 is effective when used once daily. Using it twice daily may require reducing the dosage, potentially decreasing its effectiveness.

The conversation discusses the approval of Kintor Pharmaceutical's AR-PROTAC (GT20029) for clinical trials in China for acne and androgenic alopecia. One user expresses optimism about new treatments being developed and seeks clarification on how the new drug works, specifically if it temporarily degrades the AR protein to reduce DHT sensitivity in hair follicles.

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.

Some users of RU-58841 report cardiovascular symptoms like heart palpitations and chest tightness, which may be linked to its metabolites causing lung disease. The safety of RU-58841 is uncertain due to lack of long-term data and concerns about product purity, especially from gray market sources.

GHK-Cu is a potent inhibitor of the type 1 5-alpha reductase enzyme in hair follicles, which may reduce hair loss without the side effects associated with type 2 5-alpha reductase inhibitors. The user previously experienced side effects with 5-alpha reductase inhibitors and is considering GHK-Cu as an alternative.

User wants to add RCP to regimen and asks if it can be applied with topical minoxidil and/or finasteride at night.

RU58841 may pose cancer risks due to its antiandrogen properties and lack of long-term safety data. Using it is considered a high-risk experiment with unknown potential for harm.

RU58841 is discussed as an effective hair loss treatment, with some users experiencing regrowth and reduced shedding, but concerns about safety and sourcing are raised. Users advise against purchasing from Amazon, recommending reputable sources and cautioning about potential side effects like cardiovascular issues.

Hair loss treatments Cosmerna, RU, and Pyri discussed. Cosmerna inhibits androgen receptors, but not 100%, so RU/Pyri can be used synergistically.
