Over time the 'normal' one gradually becomes 'ulled' to the creatine and so less creatine can be taken up that way. This is why you sometimes hear people saying that you need to cycle off etc... the insulin receptor neer downregulates and creatine is always accepted via this channel. Albeit, not as much will get through, but in truth you don't actually have to cycle off creatine at all.
And you're right about not loading - muscles already contain 'X' amount of creatine as it is, and it is found in beef too. the loading phase was invented by supp companies in the hope that you'd use your supply up quicker and buy more sooner.
thought you'd be interested...
