You can keep doing what you're doing until you're ready to add fish.
Not sure what you mean by adding full load, though - IME, It's always a good idea to go slow when adding fish to a new tank, even a fully cycled one. Many fish really don't like being put in a "fresh" tank (see otos, rams, etc.). Nitrifying bacteria, once present in sufficient numbers, can reproduce rapidly to adjust to increased stocking over time. You shouldn't see a significant ammonia or nitrite spike when you add a few fish at a time.
