Protein powder does NOT go bad. I've done extensive research into this because I always ask the store for their expired or near expired protein. It's always at least half price so it's a good way to buy it. The only reason the have expiration dates is because the FDA and other regulatory bodies require a date to be put on (shelf life).
As for the bars, I'm not sure. Bars aren't completely dehydrated like the powder is so you'd have to ask around."Don't count the days, make every day count"

The other thing that sticks out at me is why would they keep 'expired' protein powder in the back? Why not throw it out if it's not useable? They still make profits off of it, that's why."Don't count the days, make every day count"

im going to have to agree with muirsy here. and im going to use dry powdered egg whites as my backup example. dry egg whites have an indefinite shelf life. they are poor place for bacteria to grow (especially when dehydrated, and as raw, you have less of a chance of S than you do from the yolk). protein is keen to grabbing moisture, and moisture can lead to mold. so keep that in mind. store in a cool, dry, area in a moisture tight container.
sorry kinda got off track here. basically, because its dehydrated its a bad place for mold or something else to grow and ruin it. now, there is one thing you should note:
FAT goes rancid. its that simple. white flour can store indefinately. whole wheat has a 1 year shelf life. this means, that yes, whey protein powder will go bad. storing in a refrigerator will vastly extend the shelf life of the product, as it does with wheat flour.
so heres the skinny: the whey doesnt go bad. (per say) but the fat will cause the batch to go bad.
so yes, there is a reason it has an expiration date. if you can purchase it cheaper than usual when its expired, and doesnt smell like somethin funky, go ahead, its still good protein and will still do its job. age wont modify the protein structure. itll take about a year or so for it to go rancid, if not longer. so should be okay.
or you could just buy tubs of dehydrated egg whites and store them indefinately!
PS: looking into the egg whites thing, it seems to be more cost effective to get a can of powdered egg whites than whey protein. for the same price i paid for my 2lb tub of whey, you can get 45 servings of 24 grams, thats 2 tubs of whey :-D just a thought

No, I don't think it was a coincidence! 4 years, you pushed the envelope! I would say a couple of months beyond its expiration date, so long it is not caked or smell bad...keep a note in your pocket with the date,time that you gobbled it, just in case- for the paramedics .

I have some Cytosport Complete Whey Protein, that has "Best buy 4/2011" stamped on the side...I've been using it as a pre workout protein, and plan on using it throughout the day as a kind of meal replacement or addendum...it hasn't made me sick, and it doesn't smell bad when I mix it in liquid...so until i get sick i'll keep using it, i'd just like to know if im just consuming empty calories...i don't wanna waste it, and if i need to consume protein throughout the day, what better way than cheap almost or already expired protein. (it wasn't cheap when i bought it)
lemme know if you think it's a bad idea...

boom eat it
I have been working in a gym for a few years now. I don't have a whole crap load of money but I do eat alot of protein. I always buy expired protein, the only way I wouldn't eat expired protein is if it's caked together. That means it has moisture in it wich = bacteria. I haven't gotten sick. I wouldn't eat the bars especially if it has fruit
