How much syrup do i add to it? Do I add it before i whip it or after? thank you! 

The only way I know of that it comes is in fluid - frozen OR ready whipped/ready to use.

One does not add anything to it except maybe color or a bit of flavoring. 

I found it best to use from it's frozen state (no need to thaw it)  - just spoon it out of the carton and whip, whip, whip :)

Thank you! :)
