New on June 30, 2022: Now PG+ethanol based version is available. This product is named RuDerma. The previously launched version was formulated without PG (propylene glycol), called RuDerma PG Free.
If you ordered RuDerma before June 30, 2022, what you ordered was RuDerma PG Free. It is a version free of propylene glycol (PG), which is an excellent alternative to the KB solution based Ru 58841.
Both versions can be selected from the production options (next to the price on this page).

What is RU58841?
It is also known as RU, RU-58841, PSK-3841 or HMR-3841, and is a nonsteroidal anti-androgen (NSAA). It is also one a common SARMs (Selective Androgen Receptor Modulators). Its structure is shown below. It is nonsteroidal because it does not have the steroidal skeleton structure. It was investigated and developed by ProStrakan (a Scottish based specialty pharmaceutical company) for its potential therapeutic applications in conditions that were driven by androgens. Conditions, such as acne, hirsutism (excessive hair growth), and androgenetic alopecia (male-pattern hair loss). ProStrakan conducted two clinical studies, phase I and II, and the results of 5% RU-58841, when applied twice daily, were reported to be similar to finasteride.
