User Profile

I can't find any clear information on this: how can I test offers for active subscription plan without affecting the real users? I have an cleared for sale in-app subscription plan. I want to create introductory offer for it. I had read official document, and I don't understand how to test my new offers. Since my plan is already active, if I set the intro offer with a start date the current date, then it will affect my real users. But if I set the intro offer to start from the future, then the system Apple dialog that shows the price actually shows (and buys) the regular price.
