Finasteride 5mg

Finasteride 5mg is an oral type II 5$\alpha$-reductase inhibitor. It works by targeting and inhibiting the 5$\alpha$-reductase enzyme responsible for converting testosterone into dihydrotestosterone (DHT), the primary androgen responsible for prostate tissue growth and androgenetic alopecia (male pattern hair loss).

While the $1\text{ mg}$ dose of Finasteride is specifically indicated for male pattern hair loss (Propecia), the 5mg strength (commonly known by the brand name Proscar) is clinically indicated for the treatment of Benign Prostatic Hyperplasia (BPH). In hormone optimization and performance protocols, the $5\text{ mg}$ formulation is frequently split into smaller micro-doses to lower DHT levels and manage androgenic side effects.

Key Benefits & Applications

• Prostate Size Reduction & BPH Relief: Significantly shrinks enlarged prostate tissue, reducing urinary hesitancy, frequency, nocturnal urination (nycturia), and weak urinary stream.

• Potent DHT Suppression: Lowers circulating serum DHT levels by approximately 70%, removing the primary hormonal driver of prostate growth and scalp hair follicle miniaturization.

• Hair Loss Prevention (Androgenetic Alopecia): Prevents further recession of the hairline and thinning on the crown by protecting hair follicles from DHT sensitivity.

• Mitigation of Androgenic Side Effects: Reduces androgen-mediated side effects such as oily skin, severe body acne, and body hair proliferation caused by high DHT conversion.

• Lowered Risk of Urinary Retention: Reduces the long-term likelihood of acute urinary retention and the necessity for BPH-related surgical interventions (such as TURP).
