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 22-year-old male started taking finasteride a month ago and is seeing some progress in hair loss treatment. He is concerned about high estradiol levels but plans to continue the medication and consult an endocrinologist.
The user has been using finasteride for 15 months, minoxidil for 4.5 months, and estrogen monotherapy for 4.5 months. Their current regimen includes finasteride, minoxidil, alfatradiol, and estradiol gel.
Experimenting with trestolone as a treatment for hair loss in an attempt to avoid DHT-related treatments such as finasteride and dutasteride, and discussing the potential effects of its receptor selectivity on the androgen receptors in the scalp.
User experienced high E2 levels after taking finasteride and sought advice on lowering E2 with supplements like Tonkat ali, Fadogia, and Boron. They also used DIM, zinc, and magnesium but avoided using an AI.
A user experienced increased testosterone and estradiol levels after starting finasteride/dutasteride and is asking if these levels will return to normal over time. The conversation focuses on whether these changes are temporary.
Using dutasteride or finasteride can increase free testosterone, which may convert to estradiol, potentially causing side effects like increased estrogen levels. Individual responses vary, and some users report changes in cholesterol, hair texture, and side effects like gyno or increased sex drive.
A user with high pre-finasteride estrogen levels is asking if they need to normalize their hormone levels before starting finasteride and whether they should postpone dermarolling until they begin finasteride. The user is 21.5 years old.
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.
A user experienced unexpected hormone test results after 7 months on 1mg daily finasteride, noting a decrease in estradiol despite expectations of an increase. Other users suggested that hormone responses can vary and that finasteride might still be effective if DHT levels are within range, while also mentioning factors like circadian rhythm and stress that could impact results.
User experienced feminizing side effects from finasteride and tried RU, alfatradiol, and finasteride without success. They are now considering treatments like Stemoxydine, Zix, Minoxidil, Dermarolling, Eucapil, and a hair transplant.
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.
A user gained 10-12 kg after starting finasteride but found their estrogen levels to be within the normal range. They are concerned about potential gynecomastia but are reassured by their lab results.
A 30-year-old man experienced significant hair regrowth and improved libido after using finasteride and dutasteride for androgenetic alopecia, with no adverse effects. He plans to reduce dutasteride dosage when trying to conceive and has been using topical minoxidil since 2015.
The conversation discusses a topical finasteride therapy with hydrocortisone butyrate, estrone base, and breviline. A user suggests oral finasteride as a superior option.
The conversation discusses a transgender individual's successful hair loss treatment over 1.5 years using 2.5mg oral minoxidil, 5mg finasteride, and 8mg weekly injectable estradiol valerate. Some users debate the appropriateness of this approach within the group's goals, while others support the individualized treatment and its additional benefits for transgender individuals.
17-alpha-estradiol may work for hair loss by inhibiting 5-alpha reductase, similar to finasteride. It might lower testosterone in the scalp, reducing DHT conversion.
A 24-year-old male using topical finasteride for hair loss is experiencing thinning despite treatment and has high estrogen levels. He is seeking advice on whether high estrogen could be causing hair loss and how others with high estrogen levels have addressed it.
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.
A 23-year-old man with hair loss, despite using dutasteride, oral minoxidil, and RU58841, is considering bicalutamide for regrowth but is concerned about feminization. Alternatives like topical estrogen, JXL069, and spironolactone are discussed, with suggestions to explore thyroid levels and other potential underlying conditions.
Finasteride can cause side effects like erectile dysfunction and decreased libido, possibly due to increased estradiol from testosterone aromatization, especially in those with higher body fat. Side effects vary widely and may also be influenced by genetic factors or neurosteroid inhibition.
Estrogen injections significantly improved hair growth, particularly on the crown, after stopping finasteride. Monotherapy with estrogen led to hairline improvement, but also caused sterility and potential feminization effects.
A 25-year-old male with normal hormone levels is considering starting finasteride and minoxidil for hair loss but is concerned about high estradiol levels and potential side effects. Responses vary, with some suggesting blood tests before starting treatment and others emphasizing individual tolerance and the importance of consulting a doctor.
The user started using oral minoxidil and estradiol in August 2025, added finasteride in December, and experienced significant hair shedding in February/March. They switched to estradiol injections and are considering their hair washing routine, while another user suggested consulting a dermatologist and possibly trying dutasteride.
The user is experiencing breast tissue growth from taking dutasteride and minoxidil, and is considering reducing the dosage or stopping the medication. Suggestions include seeing an endocrinologist, using Raloxifene or Arimidex, and considering topical treatments or surgery if necessary.
The conversation discusses alternative and unorthodox hair loss treatments, including RU58841, nandrolone, and dianabol, as well as theoretical approaches involving high doses of estrogen and selective estrogen receptor modulators. These methods are considered extreme and potentially harmful but are explored for those unable to tolerate traditional 5-alpha reductase inhibitors.
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.
