Hi, okay so far I read that any medication you bring only bring what you need with the same bottle it came in, is that all I need?

next question I need help on is the duty charges.. can someone send me a direct link to info or please just fill me in, I only wanted to stay for 3 days max thanks

Whatever medication it is will need to be legal in the U.S.

I'm not sure what you mean by duty charges.  Are you bringing anything into the U.S. and leaving it there, or bringing things back from the U.S. to Canada?
