There is an inconsistency between the molecular weight and formula listed on EveryChem's product page and the analytical PDFs for 3HP and PP30, suggesting a possible error in the product description. Concerns are raised about EveryChem's business practices and lack of transparency in testing and manufacturing.

A user is making a homemade topical finasteride solution by dissolving crushed finasteride tablets in ethanol and PG. They are unsure if the final solution maintains the intended concentration after filtering and are considering adding more ethanol to ensure accuracy.

Isopropyl alcohol should not replace ethanol in homemade topical finasteride serums due to potential toxicity with frequent use. Denatured ethanol, also known as parfum or cosmetic alcohol, is a safer alternative.

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.

Researching whether pyri and enza, which are stereoisomers of each other, share the same features related to CNS penetration/GABA Inhibition; safety and efficacy when used topically at 0.5-1%; and cost comparison between the two treatments.

The conversation is about finding a pure high molecular weight hyaluronic acid for the scalp after microneedling. A user suggests using a product from The Ordinary.

PP405 is a potential hair loss treatment that inhibits mitochondrial pyruvate carriers, increasing lactate dehydrogenase activity and stimulating hair follicle stem cells. In a phase 1 trial, 31% of participants showed over 20% hair density increase with PP405 treatment.

The conversation is about the stability of pyrilutamide in different solutions. The user is asking if a 70/30 ethanol/pg solution with 4% water will degrade pyrilutamide.

The conversation discusses the steps for microneedling, specifically differentiating between medical needling (0.5-1.5mm) and cosmetic needling (0.3mm). It emphasizes the importance of cleaning and disinfecting before microneedling, regardless of needle length.

The conversation discusses the use of ethanol and propylene glycol (PG) in topical solutions for hair loss treatments, specifically Minoxidil. The user dislikes the texture of PG and questions the ideal ratio and necessity of PG in these solutions.

1 mg of finasteride is commonly prescribed because it is more effective for a larger number of people compared to lower doses, despite only slightly reducing serum DHT more than 0.2 mg. Serum DHT and scalp DHT are different, and 1 mg is believed to reduce scalp DHT more effectively, contributing to better hair growth results.

The user is experiencing scalp itching from a PG ethanol base in their hair loss treatment, which includes 0.025% finasteride and 2.5% minoxidil, and is seeking alternatives without PG or ethanol. Suggestions include Zeuss non-PG foam and Ulo, which do not use PG or hydrocortisone.

The conversation discusses using very low dose topical finasteride to achieve specific serum DHT reduction percentages. It concludes that finasteride dosage increases linearly between 5-30% DHT reduction but requires exponential increases for reductions up to 70%.

The conversation discusses the sale of a premixed KY19382 solution for research purposes, highlighting previous unsuccessful group buys and the formulation process. Prices and purchasing options for KY19382 solutions and powder are provided.

The conversation questions the lack of feedback on the effectiveness of PGE2 and setipiprant for hair loss, despite their availability. The user is puzzled by the absence of reviews or results, whether positive or negative.

The conversation discusses the differences between PG/Ethanol and KB solutions for RU58841 application, focusing on potential scalp irritation. KB solution is suggested for those allergic to PG, though both contain ethanol which can dry the scalp.

The conversation discusses Peptonix microneedling, a copper peptide serum, as a potential hair loss treatment. Users compare it to finasteride and minoxidil, noting side effects and personal experiences with these treatments.

A user is seeking advice on ordering ethanol in the UK to use with topical finasteride, considering switching from isopropyl alcohol. They mention the possibility of purchasing 99.8% ethanol from eBay's 6 Science shop.

The conversation discusses skepticism about the effectiveness and formulation of a $10 RU58841 gel from a Korean brand, questioning if ethanol is used to hold the active compounds. Concerns are raised about the feasibility of selling it at such a low price.

A 23-year-old male is experiencing diffuse hair loss and miniaturization, possibly due to high IGE levels after using tofacitinib. He seeks advice and has not yet consulted a dermatologist.

PP405 shows promise for hair regrowth by manipulating stem cell characteristics and lactate dehydrogenase, with Phase 2a trials pending. Google Ventures' $15M investment suggests confidence, but results and market availability remain uncertain.

A user is seeking advice on creating a Minoxidil-free topical Finasteride solution due to side effects and concerns about pets. They plan to use Isopropanol alcohol, Propylene Glycol, and distilled water to make a 0.02% solution, starting with 1ml applications.

There is no new information on pp405, with data collection expected to finish by the end of 2025. Users are discussing the timeline for data analysis and completion of Pelage Pharmaceuticals' phase 2 study.

PP405 is seen as a potential breakthrough for converting vellus hairs to terminal hairs, with users expressing both hope and skepticism. It is compared to treatments like minoxidil and finasteride, with discussions on side effects and marketing concerns.

The conversation discusses the use of Finastopic, a carrier for finasteride solutions by Isdin, and compares it to a standard propylene glycol (PG) solution. The user was prescribed a 1% finasteride solution using Finastopic and has been using a self-compounded 0.025% topical finasteride with minoxidil.

The user is experiencing scalp irritation from using RU58841 with a 70% ethanol and 30% propylene glycol vehicle and is considering switching to a less irritating vehicle, such as 30% ethanol with 70% squalane or emu oil. They are seeking feedback on the effectiveness and irritation levels of these alternative carriers.

OP wants to increase pyrilutamide concentration from 0.5% to 1% while already using finasteride. Users suggest waiting for a commercial 1% solution and caution against using grey market products.

ET-02, a PAI-1 inhibitor, is not proven to be more effective than Minoxidil for hair loss. Other treatments like finasteride, dutasteride, PP405, and AMP-303 are also discussed, focusing on cellular senescence and oxidative stress.

The conversation discusses the pros and cons of using propylene glycol versus ethyl alcohol in topical solutions for finasteride and minoxidil. It questions why propylene glycol is commonly used and whether ethyl alcohol might be a better option.
