5 / 1000+ resultscommunity Is there a topical androgen receptor blocker so we don't have to fuck with the enzyme and destroy our allopregnanolone, but go and hit the end target straight?
The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.
community Chat is this real? Compound called clascoterone
Clascoterone shows promising results for hair regrowth in men with androgenetic alopecia, with potential FDA approval by 2026. It acts as a topical androgen receptor blocker, offering a new treatment option with minimal side effects compared to existing treatments like finasteride.
community GT20029 China Phase II Trial For AGA Reached Primary Endpoint
The GT20029 tincture, a topical androgen receptor degrader, showed significant hair growth and good safety in a China Phase II trial for male androgenetic alopecia (AGA), with the 1% dose twice weekly identified as optimal. The company plans to initiate Phase III trials in China and Phase II in the U.S., and the treatment also shows promise for acne.
community Are there ever going to be any oral DHT blocking treatments in the future?
The discussion revolves around the need for future oral DHT blockers for hair loss treatment that don't have the side effects of current options like Finasteride and Dutasteride. One user suggests that the future of hair loss treatment will likely be topical anti-androgens, as they can target hair follicles without affecting the entire system.
community Most Promising Future Hair Loss Treatments In 2026
Promising hair loss treatments in 2026 include GT20029, a topical androgen receptor degrader, and VDPHL01, an extended-release oral minoxidil, both offering safer alternatives with fewer side effects. Other treatments like sublingual minoxidil, OND-1, JW0061, TDM-105795, and AMP-303 are also being explored.

8 / 29 results- How is Fluridil different from other DHT blockers like finasteride? Fluridil is a topical androgen-receptor blocker applied to the scalp, while finasteride is an oral 5-alpha-reductase inhibitor that lowers DHT throughout the body. Finasteride is FDA-approved and far better studied; Fluridil rests on one 43-man trial and is not licensed as a hair-loss medicine, so its long-term safety and effect size are unknown.
- Kintor Pharmaceutical: KX-826, a New Name in Hair Loss Research KX-826 (pyrilutamide) is an experimental topical androgen receptor blocker from Kintor Pharmaceutical. It is not approved as a medicine anywhere; the company reports that its China Phase III trial met its primary endpoint at 24 weeks, but the trial data has been released through corporate announcements rather than peer-reviewed journals and long-term safety is unknown.
- What is GT20029 and how does it work as a topical anti-androgen for hair loss? GT20029 is a topical anti-androgen that degrades androgen receptors to combat hair loss.
- How does spironolactone help reduce hair loss when used in topical or oral treatments? Studies report that spironolactone slows androgen-driven follicle miniaturisation by blocking androgen receptors, with most evidence in women and mostly alongside minoxidil; it is a prescription drug and its use for hair loss is off-label.
- What is pyrilutamide, and how does it help with androgenic alopecia or hair loss caused by DHT? Pyrilutamide (KX-826) is an investigational topical antiandrogen designed to block DHT at the androgen receptor in the scalp rather than lower DHT in the blood. Its sponsor has announced positive Phase III top-line results in China, but none of the data are peer-reviewed and it is not approved as a medicine anywhere.
