Combination of an Antiandrogen and a 5α-Reductase Inhibitor: A Further Step Towards Total Androgen Blockade?

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 considered by some as an alternative for those avoiding 5AR inhibitors like finasteride and dutasteride, but opinions on its effectiveness vary. Some users report similar results with fluridil and pyrilutamide, while others find pyrilutamide less effective compared to prescription treatments.

Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.

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.

The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.

Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.
