Treatment of Enlarged Prostate Gland
Finasteride (Proscar) is a very potent type II 5a-reductase inhibitor, which prevents conversion of testosterone to dihydrotestosterone (DHT). DHT is a sex hormone. In addition, it is used for treatment of benign prostatic hyperplasia (BPH), which is the enlargement of the prostate.
Finasteride inhibits 4a-reductase, and as mentioned, will prevent testosterone conversion to DHT. Studies have shown it will reduce serum DHT levels by about 65-70%, and prostate DHT levels, by up to 90%. By blocking DHT production, finasteride reduces androgen activity on the scalp; and in the prostate reduces prostate volume, which improves BPH, and reduces risk of prostate cancer.
Prevent Hair Loss
Bodybuilders will want to inhibit this conversion as much as possible to preserve hair loss, which is why finasteride is used. This is especially true when using DHT derivative anabolic steroids. Finasteride does a good job at keeping existing hair, and in almost half of men it will help grow more hair.
Finasteride is used to treat male pattern hair loss (androgenetic alopecia) in men only.Treatment provides about 30% improvement in hair loss after six months of treatment, and effectiveness only persists as long as the drug is taken.Clinical studies suggest that, with Finasteride 1 mg/day, continuously taking it for 3 months or slightly long , users can have their hair regrow, after 1 year if continuous treatment, hair growth rate is up to 48%.
Finasteride Dosage
Bodybuilders will dose Finasteride at 1mg per day to preserve hair. This is usually done during their DHT cycles.
