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.

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.

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 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.

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 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.

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.

The conversation discusses hair loss treatments, focusing on the use of topical minoxidil, microneedling, finasteride, and dutasteride, while debating the role of testosterone and DHT in hair loss. It also touches on the potential liver health impacts of these treatments and the genetic sensitivity of hair follicles to androgens.

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.

The user experienced side effects from spironolactone and is seeking alternatives for androgenetic alopecia (AGA), considering saw palmetto but unsure of its effectiveness. They are also exploring the possibility of using topical spironolactone, despite availability challenges.

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 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.

The conversation discusses using a multimodal approach to treat androgenic alopecia, including substances like gamma-linolenic acid, DHA, sulforaphane, melatonin, cetirizine, astaxanthin, fisetin, apigenin, curcumin, limonene, genistein, and berberine. Users also mention using ketoconazole, minoxidil, and low-level laser therapy (LLLT) as part of their hair loss treatment regimens.

Hair loss treatments, specifically 5AR inhibitors, can impact neurosteroids and sexual health. The effects of topical fin/dut on tissue-specific DHT levels are unclear.

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.

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.

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

The conversation discusses treating male pattern baldness with topical products containing Saw Palmetto extract. Specific treatments mentioned include Minoxidil, Finasteride, and RU58841.

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.

The treatment for androgenetic alopecia involves using finasteride and minoxidil with intense exercise and cold exposure to boost metabolism and reduce androgenic effects, potentially leading to hair regrowth. This approach may activate biological pathways for improved hair and overall health.

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.

A 19-year-old concerned about long-term effects of 5AR inhibitors on physical appearance. They have used finasteride and plan to try dutasteride or RU58841; responses suggest improved skin, hair, and confidence.

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.

The conversation is about managing allopregnanolone deficiency caused by 5-alpha-reductase inhibitors like finasteride or dutasteride. Specific treatments discussed for hair loss include Minoxidil, finasteride, and RU58841.

The user plans to switch from minoxidil to finasteride or dutasteride for hair loss, while managing hormones with aromatase inhibitors and SHBG blockers. They seek advice on the best options for these treatments, considering past side effects and future therapies.

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.

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 user increased their steroid dosage and noticed hair shedding, so they adjusted their regimen by reducing steroid doses and adding oral dutasteride. They are also experimenting with combining RU-58841 and KX-826/pyrilutamide in minoxidil to address hair loss.

A 23-year-old has been using finasteride, dutasteride, and spironolactone to combat hair loss and hormonal acne, with mixed results and concerns about side effects. The user is experimenting with spironolactone despite its potential risks, hoping for skin and body hair improvements.

Topical spironolactone is available in the UK for men to block androgen receptors locally. The user seeks opinions or experiences from others who have used it.
