Mixture Effects of Endocrine Disrupting Compounds In Vitro

Pyrilutamide and RU58841 are androgen receptor antagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.

Bicalutamide blocks androgen receptors, preventing testosterone and DHT from binding, which can help with hair loss but may cause feminization. It is not recommended for those who do not want feminization effects.

Pyrilutamide is believed to be more effective than RU58841 and 1 mg finasteride in treating hair loss, with no systemic hormonal effects and the potential to block more than 31% of scalp DHT. It may also antagonize scalp testosterone due to its action as an androgen receptor antagonist.

Some users have experienced good hair regrowth with estradiol, cyproterone acetate, spironolactone, and bicalutamide, but these treatments may cause feminization and other side effects. It's advised to consult a doctor before using these treatments, as they can lower testosterone and have significant risks.

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

Pyrilutamide is officially available for purchase, and users suggest Fluridil as an alternative topical anti-androgen. Some users report positive results with pyrilutamide from Koshine.
