Actual answer: He had a grand total of one bottle, worth 24 hours. It takes 2 months to make because, as hermione says, "You've got to let it stew". He used one mouthful on Slughorn, then gave the entire rest of the bottle to his friends in the sixth book, and them splitting it kept them all alive. After that Harry was constantly on the move and on the run from the law for a good chunk of it. He could not a) be seen buying the ingredients and b) sit still in one place for two months to brew a potion or he'd certainly be caught.
