Does RU58841 in Glycerin works?

Product 1/23/2026

RU58841, oral and topical minoxidil, finasteride, and ketoconazole shampoo led to significant hair regrowth, though some suspect a hair transplant. Concerns about RU58841's side effects, like anxiety and heart issues, were discussed.

RU58841 may cause heart-related side effects like palpitations and chest pain, though evidence is mostly anecdotal. Users report mixed experiences, with some stopping due to side effects and others using it without issues, but concerns about its safety and sourcing remain.

Minoxidil with alcohol and propylene glycol was more effective than non-alcohol versions, and RU58841 worked best in a non-water-based solution. Oral finasteride showed better results than topical, despite side effects; microneedling and tretinoin worsened hair loss, and PRP was only helpful when younger.

A user has been using minoxidil for hair loss and has seen positive results, but is seeking additional treatments to enhance its effects. One suggestion given is to use finasteride alongside minoxidil.

Pyrilutamide, a potential hair loss treatment that is currently in development and may be available soon; an androgen receptor degrader which is also being developed as a potential treatment for hair loss; and the comparison between Pyrilutamide, finasteride, minoxidil, and RU58841.
