Description:
Propecia (finasteride) is used to treat male pattern baldness (androgenic alopecia) in men. Oral use though will reduce DHT levels systemically, which may adversely affect training and sex drive.

It is also used in combination with doxazosin in the treatment of benign prostatic hyperplasia (BPH).] Finasteride is an orally active testosterone Type II 5-alpha reductase inhibitor, inhibiting the enzyme that converts testosterone to dihydrotestosterone (DHT).

Topically (on the scalp itself) it is of some effect in minimizing further hair loss. In combination with Nizoral and spironolactone (which smells awful, by the way) it can actually reverse loss moderately.

For use in cycles with testosterone, I don't think it is bad at all. One simply doesn't want less DHT than normal. As the amount of testosterone in the system increases, the amount of finasteride needed to keep levels down to normal increases. I consider 5 mg/day reasonable at the gram per week level, and proportionally less at lower dosages of testosterone.
