Well I think this question is not for me. I just use Extagen and have good results. I'm not a doctor and I wouldn’t recommend any drug. I just say that it works for me.
Extagen is not viagra . I have tried both so I know whereof I speak. Extagen is a working and safe drug and viagra is not. I order it through the web but may be there are other ways.
The action of extagen is not the same as viagra's because it just works. I take a course and forget about it. Then I take a course again if it's necessary.
