Two Chinese suppliers provided legitimate RU58841, confirmed through a free drugtesting service. The vendors were Shaanxi Greenyo Biotech and Lyphar, found on Made-in-China.
RU58841 powder from a lab supplier was tested at a free drugtesting service. The discussion includes using Minoxidil and finasteride for hair loss treatment.
A new therapy aimed at destroying DHT receptors in the scalp is still in early trials and may take at least 5 years to become available. A sugar-like solution similar to Minoxidil is also in early testing stages and not yet commercialized.
Kopexil (Aminexil) is not approved as a drug in the US and Europe because it is marketed as a cosmetic, which requires less testing and regulation. L'Oreal's 1.5% Aminexil is noted to reduce hair shedding, but its efficacy as a drug is not proven.
Pyrilutamide, a new drug being tested to combat hair loss that has been found to perform comparably or better than finasteride and dutasteride in the initial 6 months of treatment with minimal reported side effects.
