Dutasteride at 2.5 mg/day reduces scalp DHT by 80%, while 0.5 mg/day reduces it by 50%, with minimal difference in side effects. Users often combine it with finasteride, RU58841, and minoxidil for better hair loss management, though side effects like dry skin and pimples are noted.

OP has been using daily oral finasteride 1.25mg for 5 months with noticeable progress and no side effects. They chose this dosage by cutting 5mg pills into quarters due to cost.

Finasteride users cannot donate blood due to potential risks to pregnant women, requiring a one-month cessation before donating. Dutasteride requires a six-month deferral, and topical applications are not restricted.

Topical dutasteride 0.05% is reported to outperform oral finasteride with minimal side effects, but concerns about study bias exist due to company funding. Some users report mixed results with topical dutasteride, noting issues with skin penetration and systemic absorption.

A user from China is participating in a clinical trial for Pyrilutamid, a potential hair loss treatment originally developed for prostate cancer. They've experienced no side effects except initial scalp itchiness, and will share results after the year-long trial.

Potential side effects of 5AR inhibitors like finasteride and dutasteride. Users debate risks, benefits, and personal experiences with these hair loss treatments.

The user experienced a significant drop in libido and erectile issues after increasing their finasteride dosage, combining oral and topical treatments. They plan to take a break and resume using a lower concentration of topical finasteride to manage side effects.

The conversation is about a person using dutasteride and minoxidil for hair loss, considering adding RU58841 and PP405 for more density. They are seeking advice on using these treatments and exploring other options like GT20029.

A user experienced increased pimples and cysts after two years on dutasteride, possibly due to hormonal changes. Suggestions included seeing an endocrinologist, using supplements like boron and DIM, adjusting diet, and reducing body fat to manage side effects.

PP405 shows promise in activating dormant hair follicles and increasing hair counts but lacks detailed efficacy data compared to minoxidil and finasteride. Opinions are mixed, with some optimism and skepticism about its effectiveness.

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.

People are discussing obtaining and testing PP405 for hair loss treatment, with concerns about its purity and effectiveness. Some are considering delaying hair transplants, while others suggest using existing treatments like finasteride and minoxidil.

Finasteride and Dutasteride do not cause dry eyes by damaging meibomian glands, as these glands continue to function normally even when DHT is blocked. Some users report dry eyes with these medications, but others suggest supplements like Omega-3 or krill oil as potential remedies.

The conversation discusses GT20029, a drug in Phase II trials that targets androgen receptors with minimal systemic effects, and TDM-105795, a growth stimulant with a different mechanism than minoxidil that may revive papilla stem cells. Both are potential new treatments for hair loss.

The conversation discusses the potential for developing a biologic "DHT sponge" to neutralize DHT in the bloodstream as a treatment for hair loss, suggesting it could be more targeted and have fewer side effects than current treatments like finasteride and dutasteride. Concerns include the complexity, cost, and potential side effects of such a treatment, as well as skepticism about its feasibility and market interest.

A user experienced initial side effects from finasteride, including erectile dysfunction and emotional changes, but later noticed increased muscle mass and assertiveness. Hormonal tests showed elevated estrogen and prolactin levels, which slightly decreased over time; the user plans lifestyle changes to see if they help.

The user has DUPA and suspects autoimmune activity as a cause. They have tried various treatments including finasteride, minoxidil, dutasteride, pyrilutamide, estrogel, hydrocortisone, and clobetasol, and are now seeking a long-term immunosuppressant.

The user experienced hair regrowth after 5 months on 5 mg oral minoxidil and 1 mg dutasteride, following a year of ineffective finasteride use. They noticed progress after an initial shedding phase and hope for further improvement, with expectations of near-max regrowth around 18 months.

A 45-year-old male experienced significant hair regrowth using 0.5 mg dutasteride and 1.5 mg minoxidil after initially starting with finasteride. He reports no major side effects, except increased hair growth in unwanted areas, and attributes his success to being a good responder to the medication.

A user discovered they have naturally low DHT levels and is concerned about taking finasteride, which could further lower these levels. They are seeking advice on whether to proceed with the treatment given their hormone levels are within the normal range.

The FDA policy change may speed up approval for hair loss drugs like PP405, VDPHL-01, and Breezula by potentially eliminating the need for a second confirmatory Phase 3 trial. Approval timelines could be as early as 2028 for some treatments if Phase 3 results are strong.

User tries Fluridil for hair loss after topical finasteride caused issues. Others doubt its effectiveness and cost.

The user is experiencing hair loss after a hair transplant and is considering using fluridil (Eucapil) and possibly alfatradiol as treatments, as they couldn't tolerate finasteride or minoxidil. The manufacturer of Eucapil confirmed they won't produce higher concentrations due to lack of efficacy.

The user recovered from Post-Finasteride Syndrome (PFS) using a specific hormone protocol after trying finasteride and dutasteride. They now help others with PFS by reviewing blood work and offering personalized advice.

A 27-year-old male physician improved hair density using minoxidil 5% foam and finasteride 1mg every other day, with initial sexual side effects that subsided. He recommends trying finasteride for a year but warns against dutasteride due to potential liver effects.

Hair loss is linked to DHT, with treatments like finasteride and minoxidil being common but not definitive. Economic interests influence research, and there is potential for new treatments like PP405 and RU58841.

Dutasteride at 0.5mg blocks 50% of scalp DHT, while higher doses like 1mg and 2.5mg block more, with 2.5mg blocking up to 80%. Some users report better results with lower doses, and there's confusion about the effectiveness of different dosages on scalp versus serum DHT.

Pyrilutamide is believed to be more effective than RU58841 and 1 mg finasteride in treating hair loss, with no systemic hormonal effects and the potential to block more than 31% of scalp DHT. It may also antagonize scalp testosterone due to its action as an androgen receptor antagonist.

The conversation discusses using topical Calcipotriol and Valproic Acid for hair loss, focusing on their mechanisms involving the VDR receptor and Wnt/beta-catenin pathway. Specific treatments mentioned are Minoxidil, Finasteride, and RU58841.

A user started taking 0.5 mg of finasteride daily and noticed watery semen, questioning if it's normal or if they should adjust the dosage. Another user suggested it might indicate reduced fertility and may not improve.
