GT20029 and PP405 are discussed as potential alternatives or complements to finasteride for hair loss treatment. GT20029 is entering phase 3 trials, while PP405 is seen as promising for regrowing hair and possibly eliminating the need for other treatments.

The conversation discusses using gartanin from mangosteen mixed with castor oil to degrade the androgen receptor for hair loss treatment. Alternatives like setipiprant, minoxidil, and dermastamping are also mentioned, with concerns about cost and potential side effects.

The conversation discusses the lack of public information on the chemical structure of PP405, a hair loss treatment, and the challenges of synthesizing it without a patent. It also explores a patent related to hydrogen-based topical formulations for reducing oxidative stress and inflammation.

HMI 115 did not work as expected for hair regrowth in humans, unlike in macaque monkeys. There is anticipation for further research on prolactin's role in hair loss, with expectations that pharmaceutical companies will likely solve this before universities.

Kintor plans to release pyrilutamide foam and a plant-based Koshine by year-end, with GT20029 progressing in their pipeline. Users are pleased about the absence of propylene glycol (PG) in the new products.

GT20029 and pyrilutamide are both androgen antagonists but work differently; GT20029 degrades the androgen receptor, while pyrilutamide blocks DHT from binding. GT20029 is expected to have similar efficacy to CosmeRNA.

Pelage Pharmaceuticals is developing PP405, a topical treatment for hair growth, currently in Phase 2a trials. There is skepticism about the company's claims, and no fast-tracking approval timeline has been detailed.

A user wants to make a solution for RU58841 and finasteride powder using only glycerin and asks if ethanol is necessary. They are seeking advice on whether glycerin alone is sufficient.

The conversation is about making a solution of RU58841 using propanediol instead of propylene glycol due to skin irritation. The user seeks advice on whether this substitution is acceptable.

The conversation discusses using P5P (Vitamin B6) supplements to reduce elevated Prolactin levels and concerns about its potential effect on increasing DHT levels. The user is not currently using finasteride or any anti-androgens.

PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.

Treatment options for female alopecia androgenetica, discussing the availability of spironolactone online in The Netherlands and other potential treatments like finasteride, minoxidil and RU58841.

Kintor's GT20029, a treatment for hair loss, has completed Phase 1 successfully, showing promise as an androgen receptor degrader that could potentially regrow hair. It is considered more effective than Pyrilutamide, with infrequent dosing and minimal systemic absorption.

The conversation discusses hair loss treatments, mentioning minoxidil, finasteride, RU58841, VDPHL, GT20029, and follicle cloning as potential solutions. It also reveals that the discussion about PP405 was an April Fool's joke.

Amplifica is testing a compound called AMP-303 for hair loss, but it's not Scube3 or osteopontin. The timing for the results from the clinical trial is unknown.

Selling KY19382 powder, a novel activator of Wnt/β-catenin signaling, and Kolliphor EL liquid for vehicle formulation. KY19382 is a growth agonist.

The user has been using MinoxidilMax Latanoprost 0.01% and noticed an increase in hair density after years of stability on finasteride and minoxidil. They are seeking help to find a higher dosage of Latanoprost or a reliable source to purchase the powder to make their own, without a prescription or high cost.

The post discusses the use of latanoprost foam for hair growth, with the user expressing concerns about its efficiency and safety. The user is currently using topical dutasteride, which maintains their hair but doesn't promote regrowth, and is seeking a product that doesn't affect hormone levels.

Increasing the sult1a1 enzyme on the scalp may improve response to topical minoxidil. The user suggests using a baking soda solution, DMSO, and tretinoin to enhance enzyme activity and minoxidil effectiveness.

Pelage is delaying the start of phase 3 trials for PP405 to 2026 due to necessary regulatory processes, despite having $120 million in funding. Users discuss the potential of PP405 for hair regrowth, with some expressing skepticism and others hopeful for new treatments like Breezula.

Spironolactone and finasteride are not recommended for women planning pregnancy due to birth defect risks. Both need to be stopped months before conception, and finasteride is generally not advised for women.

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. 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.

Various hair growth treatments were discussed, including microneedling, bimatoprost, setipiprant, stemoxydine, PGE2, CB-03-01, WNT Beta-Catenin upregulators, KY19382, topical estrogen, IGF-1, GH, MK-677, oral castor oil, fisetin, resveratrol, cetrizine, and lactic acid. Users shared experiences and sources for these treatments, with some expressing interest in topical solutions and others noting the lack of FDA approval or scientific evidence for certain options.

Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.

OP asked if a product from Amazon is sufficient to dilute finasteride. A user advised against using propylene glycol alone, suggesting a pre-made solution instead.

The conversation discusses a last-resort hair loss treatment combining topical finasteride, minoxidil, melatonin, and progesterone, with claims that topical finasteride can inhibit up to 52% of scalp DHT. One reply clarifies that progesterone is not an anti-androgen but has anti-androgenic properties because it competes with androgens for receptors.

PP405, a potential hair loss treatment, is facing delays in releasing Phase 2 results, causing frustration among users who compare it to past failed treatments. Despite skepticism, some remain hopeful about PP405's future, while others discuss alternative treatments like Clascoterone and its expected market release.
