what is the shelf life?

I purchased a large quantity of this item last April 2012 and there is no expiration date. I would guess the shelf life lasts for years in sealed packets.

Hi,Shelf life is 6 months to 1 year depending on the region you live in. High humidity 8 months, low 1 year. Thanks,Joe

I always refrigerate mine. Not sure what the shelf life is, as it doesn't last that long in our home.

I am not sure the shelf life. I have been taking this one for two months. I can really REALLY tell a difference in my memory. I no longer have the 'fog' that comes with chronic fatigue. Huge difference that is greatly appreciated.

I am not sure of the shelf life. I had to stop using it because it hurt my skin (made it feel like it was burning).

Really not sure but have had for awhile and still good. Works fine. Maybe you can google shelf life.

Expiration date or shelf life is the final day that product is useable.we also have ( sell by date ) that means the product can be sold by that day ,and normally can be used up to six day after the sell date.

The shelf life is about 2 years. They will last longer if you store them in an airtight container.

I am uncertain of the shelf life. We used one and did not open the other for at least two weeks and it was still fresh.

My experience is that these batteries last about 2 years in use. I don't know about shelf life but I wouldn't take the chance on it.

We use it right away, so we don't know the shelf life. It works, but sometimes needs to be reapplied.

I believe it has a shelf life of over one year, maybe more! ...that's my experience, works great each time.. I buy several each yr for my use.

The shelf life on mine was roughly 1.5 years. Mine is dated 4/16 and I got it a month or two ago.

As a general rule, the shelf life is 9-12 months. All depends on how the product was stored in your home (a cool dry place). Hope this helps to answer your question.
