First you have to find out where it leaked from-- it's a sealed system. Once the leak is fixed, you will need to draw down a vacuum and see that it holds (ideally a couple hours, in practice often only a half hour). Then you fill by weight to the capacity of the system.

There are do-it-yourself products, but generally they won't produce the same result. Many AC shops offer and inexpensive service to identify the leaks, which often involves pressurizing the system with nitrogen.

Good luck!
