If you wanna do it right, go have all your hormone levels checked....fill out a "symptom" questionnaire, and know what symptoms mean what....then, after seeing the test results and combining them w/the symptoms, have levels that are out of balance, or otherwise low and causing adverse conditions, bioidentically replaced....
I recently did a saliva panel and found that I was low in progesterone of all things....thought that was a womans hormone, but I was incorrect....heres the good news, read this.....

now , what if I would have just blindly said, ok, it must be a dht problem, and blocked it w/finasteride....?
Thats why I have always said that EVERYONE should be tested before you take fin, and monitored throughout....
and that fin isnt the answer in every situation...if it was, why are we all still here, getting hairtransplants and searching for the best maintenence program?
