I read somwhere that if you are concerned about possible side effects from finasteride, you should take a blood test before you start taking it. That way, you can do another blood test if you have sex problems and the test might give you a hint to what the problem is. Tomorrow i'll see my dr. and I want to know what i should test for? I read somewhere that I should test the testo/estrogen and Zink?? Please advice. Btw, why zink?
