I have been researching other hair removal methods quite recently. They are either painful, costly, time-consuming, difficult to DIY, or all of the above. These androgen blockers seem interesting.

Some quick questions:
1. Is it cost effective? (how much does it cost exactly??)
2. Does it inhibit/minimize ALL hair growth (even on head), or just unwanted facial and body hair?
3. Other than osteoporosis, are there any other significantly dangerous long-term effects?

Any help will be greatly appreciated!
