I'm using Finasteride. I buy 10 5mg tablets for NT328. I chop each tab in 4 pieces (1.25mg) because the liver/kidneys can't process more than 1mg daily.
So NT328/40 days = NT8.2/day. Affordable, and I've seen results within two months.
Alternatively, I could just man up and go bald gracefully.
Possible side effects include impotence, decreased ejaculation, and a bushy unibrow
