Reading this web site, recomends taking cialis 5mg for 26 weeks only. I hav bhp and taking Avodart .5mg is causing me problems. The side effects, cramps and ed are not what I want. If I have to suffer with side effects I would reather take cialis 5mg so I will not have ed plus have to take testerone shots every two weeks. My bhp is not going away so I need to take cialis longer than 26 weeks, if it works.
