You are right, you dont have to load it . But I would start it the m2 way ahead of when you wanted to get a tan. The purpose of loading is to get it in your system , which usually needs to be about 15 to 20 mls. So if you are running a maint dose of 1 to 2 mgs a week , well you do the math. The problem I think with loading is , people do too much at one time.
