Analytical Chemistry Studying Historical Pharmaceuticals and Health Care Formulations

The conversation is about finding a reliable Chinese source for pyrilutamide or RU58841, ideally with a third-party Certificate of Analysis from Janoshik Analytical. The user is seeking recommendations for these hair loss treatments.

Two Chinese suppliers provided legitimate RU58841, confirmed through a free drug testing service. The vendors were Shaanxi Greenyo Biotech and Lyphar, found on Made-in-China.

A user bought questionable RU58841 powder from AliExpress and seeks a way to test its composition in Europe. Another user suggests using Janoshik for testing.

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 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.

Users discussed the effectiveness of Everychem's solution, similar to PP405, with some reporting improved hair thickness and new growth. Concerns were raised about safety and the legitimacy of the product, with some users advising against purchasing research chemicals.
