Description
Product description

RU58841 powder CAS 154992-24-2 is an androgen receptor antagonist and is being studied for its potential in treating hair loss, especially male pattern baldness. It stimulates hair follicles by blocking the hormones that cause hair loss, promoting hair regrowth.
Despite the lack of official approval, RU58841 is very popular in the hair loss research community and among some hair loss patients, who purchase the powder form and prepare it into a 5% concentration topical solution by themselves.
The uniqueness of RU58841 lies in its local mechanism of action:
Blocking androgen receptors: It is a competitive androgen receptor antagonist. When applied locally to the scalp, it binds to androgen receptors in hair follicles, thereby physically preventing androgens.
Non-systemic: Unlike products like Finasteride, RU58841 is designed to act only at the application site, reducing absorption into the bloodstream and thus avoiding potential systemic side effects.
Preventing hair follicle miniaturization: By blocking the harmful effects, RU58841 helps prevent hair follicle atrophy (miniaturization), thereby maintaining existing hair growth and promoting new hair growth.

How to use RU58841 powder CAS 154992-24-2 correctly?
RU58841 is mainly used for the treatment of androgenetic alopecia. By blocking the androgen receptors in hair follicles, it inhibits hair loss. At the same time, it can assist in improving androgen-dependent skin problems such as acne and hirsutism, and is also used in research related to prostate cancer cells. When in use, prepare the solution by yourself: Dissolve it with a solvent such as Minoxidil solution, commonly at a concentration of 5% (3g powder mixed with 60ml solvent), and stir at room temperature until completely dissolved. Apply once a day to the bald area within 30 minutes after washing your hair. Avoid contact with the eyes. For short-term storage, it should be sealed and kept away from light (≤25℃). For long-term storage, it should be frozen at -20 ℃. The shelf life can reach up to 3 years.
