I wrote a thread a whlie back about how to possibly spot a fake Creed. Shining ultraviolet light on that fuzzy name patch thing should reveal some tiny, glowing threads, mostly glowing a light greenish color, and perhaps a few red ones as well (there's only one red fleck on my box of Acier Aluminum). These threads are similar to what you would see if you shine UV light on checks, but they're shorter. You can get a UV LED keychain light for under $10 if you look around. It's better than lugging a compact flourescent tube around with you, and they're actually quite handy.
Also, don't worry about the bottle being two years old. Even good 'ol Ollie Creed himself said that a couple-year-old bottles are best because all of the aroma components have had time to mingle (of course, he could also be trying to push old stock...).
