The effects of finasteride powder on fitness
Finasteride is a 5α-reductase inhibitor primarily used to treat male pattern baldness (androgenetic alopecia) and benign prostatic hyperplasia (BPH) . In the fitness community, some users try it to reduce DHT (dihydrotestosterone)-related side effects (such as hair loss and acne), but caution is advised regarding its potential impact on muscle growth, sexual function, and hormone balance .
1. Core Functions and Mechanisms
✅ Inhibit DHT production (anti-hair loss/acne )
Blocks the conversion of testosterone to DHT → DHT levels drop by 60-70% (reduces hair follicle attack).
Clinical Data :
hair loss reduced by 80%+ after 3-6 months (for patients with male pattern baldness).
Steroid users taking finasteride can reduce the risk of acne and seborrheic dermatitis .
