I have asked a similar question once before this one is a little different. I did try and figure this out on my own but this stuff really confuses me. I googled the translations and it still won't compute in my head. I got some liquid Viagra it says 30ml 25mg/ml. Now I am trying to figure what 25mg would be if measured in a cc. I know to some this is highschool math but it might aswell be triganometry to me. If anyone can help would appreciate it.
