The conversation discusses the effectiveness of anti-androgens for hair loss, with a preference for topical treatments like RU58841 over oral options due to better scalp concentration and fewer side effects. Topical finasteride at 0.1% may provide some results, especially when combined with a topical androgen receptor antagonist like RU58841.

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 relative strength of Pyrilutamide compared to RU58841 in terms of androgen receptor binding affinity. It has been noted that Pyrilutamide is 4x stronger than RU58841, with a higher binding affinity than DHT itself.

Clascoterone in Winlevi, a topical AR antagonist, is being re-examined due to concerns about HPA axis suppression in adolescents, but it's unlikely to be banned for adult use in androgenetic alopecia (AGA). The European Medicines Agency recommended refusing Winlevi for acne vulgaris, but this may not affect Breezula's approval for AGA.

RU-58642 is a powerful anti-androgen that was not developed further, possibly due to safety concerns or financial reasons. RU58841 is a topical alternative, but it is less effective than finasteride and dutasteride, and its long-term effects are not well-studied.

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.

The conversation lists hair loss treatments including finasteride, dutasteride, RU58841, pyrilutamide, breezula, and fluridil, and suggests ketoconazole as another option. Some users warn against using certain treatments like cyproterone acetate, bicalutamide, and spironolactone due to their strong anti-androgen effects and potential impact on masculinity.

GT20029 is a topical treatment that degrades androgen receptors to prevent hair thinning and loss, potentially offering fewer side effects than systemic treatments like finasteride. Concerns include its impact on hair texture and potential systemic effects, with market availability speculated in 3 to 5 years.

The conversation discusses alternatives to RU58841 for hair loss treatment, with suggestions including topical spironolactone, peppermint and rosemary oils, and saw palmetto. The user also considers ordering RU58841 from China but finds it too expensive.

The user experienced decreased libido with saw palmetto and is now considering topical anti-androgens like RU58841, pyrilutamide, and topical dutasteride for hair loss. Minoxidil is also mentioned as a potential addition, but the user is cautious about side effects and availability of treatments.

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.

RU58841 is considered effective by some users, but finasteride and minoxidil are commonly used with varying dosages to manage side effects. Users report different experiences with treatments like pyrilutamide, fluridil, and RU58841, with some seeing results and others not.

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.

RU and Pyri block androgen receptors to prevent hair loss but may also hinder hair regrowth since they prevent testosterone, which can stimulate hair growth, from binding to these receptors. The user is questioning if this understanding is correct.

The user is considering RU58841 and has been using dutasteride since age 17. They are seeking affordable SARD options, mentioning ASC-J9, GT20029, and AH001.

Fluridil may decrease the number of androgen receptors in hair follicles by up to 95%. This suggests a different action mechanism from other non-steroidal antiandrogens like RU58841, indicating they might be used together.

A 30-year-old woman with androgenetic alopecia is considering bicalutamide to slow hair loss but is concerned about its impact on muscle growth due to its anti-androgen effects. Alternatives suggested include dutasteride, spironolactone, RU58841, and minoxidil, with concerns about bicalutamide's side effects.

The conversation discusses adding either RU58841 or pyrilutamide to a hair loss treatment regimen that already includes oral dutasteride and oral minoxidil. RU58841 is considered the stronger anti-androgen but may have more side effects.

Pyrilutimide and CB-03-01, two treatments for hair loss, have similar clinical trial results despite different binding affinities to androgen receptors. Factors other than binding affinity, like the time a drug stays bound to the receptor, may influence their effectiveness.

CB-03-01 is a topical anti-androgen with low absorption, offering potential as a side-effect-free alternative to Finasteride/Dutasteride for hair loss. It's in stage 2 clinical trials for acne and showing promise for male pattern baldness.

Dutasteride may inhibit androgen receptors in addition to reducing DHT, potentially explaining its effectiveness over finasteride for hair loss. Concerns about its impact on muscle growth are debated, with some suggesting no significant effects.

RU58841 is discussed as a topical anti-androgen for hair loss, but its effectiveness and safety are not well-documented, leading to mixed opinions and experiences among users. Some combine it with finasteride, but concerns about side effects and lack of FDA approval limit its popularity.

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.

Bicalutamide blocks androgen receptors, preventing testosterone and DHT from binding, which can help with hair loss but may cause feminization. It is not recommended for those who do not want feminization effects.

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 conversation is about the effectiveness and production of GT20029, a drug being developed as a topical androgen receptor degrader for hair loss, and whether it can fully degrade androgen receptors or only partially. It also discusses the drug's potential unique working mechanism and synthesis by a company called Anagen.

Comparing the effectiveness of RU58841, Pyrilutamide and CB-03-01 as treatments for hair loss, with people discussing different aspects such as binding affinity, time of inhibition, safety data and cost.

Clascoterone, a topical anti-androgen, is generating interest for potentially fewer systemic side effects. Users are curious about its effectiveness and details like concentration and duration of use.

Female considering adding topical anti-androgen, seeks advice on RU58841 or pyrilutamid's binding affinity compared to spironolactone.

The user is using finasteride, minoxidil, and ciclopirox shampoo for hair loss and is considering adding a topical anti-androgen like RU58841, Clacosterone, or KX286. They have scheduled a hair transplant and are concerned about the cost and effectiveness of future treatments.
