The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.
People are discussing the anticipated release of PP405 phase 2a results, expected by the end of March, with some skepticism about its effectiveness. There is cautious optimism due to past experiences with similar treatments like Breezula, despite concerns about the lack of presentation at the AAD 2026 conference.
The conversation discusses the mechanism of action of alfatradiol (17 alpha estradiol) in treating hair loss. It explores theories that it either inhibits 5 alpha reductase to prevent T->DHT conversion or aromatizes scalp T into 17-alpha-estradiol to save hair.
The potential of using a specific antibody, HMI-115, as a treatment for hair loss alongside traditional treatments such as minoxidil and finasteride. The user suggests trying either a 240 mg or 30 mg dose to see if it works.
RU58841's side effects may be exaggerated due to anxiety, with some users experiencing no issues and others reporting symptoms like chest pain. RU58841, minoxidil, and finasteride are used for hair loss treatment, with varying individual reactions.
The conversation is about testing the effectiveness of RU58841 for hair loss, with the user planning to increase their dose to 30 mg per day along with 20 mg of Minoxidil. The test results showed approximately 70 mg/ml, which the user considers a good result.
RU58841 worsened hair condition, causing thinning and unusual patterns. The user stopped using it two months ago but hasn't seen recovery, and there's speculation about androgen receptor upregulation.
Dutasteride can cause hair shedding even with suppressed testosterone levels due to previous damage from DHT. Hair shedding is often a sign of damaged hair being replaced by healthier growth.
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.
27-year-old female experiences aggressive hair thinning and hirsutism despite normal testosterone levels. Spironolactone and 2% minoxidil were ineffective; high DHEA sulfate levels may be the cause.
The experiences of users who have used RU58841 to treat hair loss, including both positive and negative effects. Some side effects reported include chest pain, joint pain in the hands, tinnitus, and increased heartbeat.
The conversation is about determining which type of Saw Palmetto, either Chamaerops humilis or Serenoa repens, is effective for inhibiting the 5 alpha reductase enzyme related to hair loss. Specific treatments mentioned are Minoxidil, finasteride, and RU58841.
The post discusses the completion of the HMI-115 Australian Phase 1 Trial for hair loss treatment. The user speculates about the potential early release of the trial results.
Researching the release of phase 2 trials for pyrilutamide, a potential hair loss treatment, and discussing other treatments such as Minoxidil, Finasteride, and RU58841.
New product Tomorrowlabs HSF targets hair loss through HIF pathway indirectly by removing scalp iron. Minoxidil and Stemoxydine also relate to HIF pathway.
The user does not respond well to minoxidil and is seeking an alternative to Tretinoin to upregulate sulfurtransferase activity for hair loss treatment. No specific alternative treatments were mentioned.
Some individuals experience side effects from 5AR inhibitors like finasteride and are considering hair transplants without these medications, with some opting for surgeons like Dr. Zarev. Others are exploring alternative treatments and waiting for new medications in development, while some discuss managing side effects through lifestyle changes or additional medications.
Reducing the dose of RU58841 from 25mg to 7.5mg topically helped minimize heart palpitations. Users discussed the cardiac effects of RU58841 and minoxidil, noting that no treatment is completely free of side effects.
The conversation discusses androgen receptor degraders for hair loss, highlighting their potential advantages over traditional AR blockers like RU58841 and pyrilutamide. Concerns about the safety and cost of these treatments are also mentioned.
The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.
Dutasteride and finasteride have similar risk profiles despite Dutasteride blocking more types of 5AR in the brain. Some users report no mood issues with either drug, and it is suggested that Dutasteride's larger molecular size may limit its ability to cross the blood-brain barrier.
Users discuss finding reliable sources for RU58841, focusing on lab tests, batch consistency, and community reputation. Some mention using alternatives like pyrilutamide.
Fluridil degrades androgen receptors, which are prevalent in the scalp and other tissues. People with androgenetic alopecia (AGA) may have higher expression of these receptors and 5AR activity in affected scalp areas.
The potential availability of a new hair loss treatment called HMI-115, which has shown promising results in experiments on monkeys but is not yet available to the public. Replies cautioned against using unproven substances from shady labs.
Topical 2-deoxy-D-ribose (2dDR) regrows hair in mice almost as well as 2% Minoxidil. However, 2dDR may contribute to oxidative stress and hair loss due to the formation of advanced glycation end products (AGEs).
A user ordered RU58841 from a Chinese supplier, found it to be less than 99% pure, and plans to try a different seller next time. Concerns were raised about impurities, but the user believes they are likely inactive fillers rather than harmful substances.
Chime Biologics and Hope Medicine are speeding up the launch of a first-in-class antibody drug, HMI-115, for endometriosis and androgenic alopecia. The treatment involves a series of subcutaneous injections, has shown promising results in phase 1, and continues to promote hair regrowth even after the treatment is stopped.
