Is this the same PG that can be used 50/50 w/ distilled water for humidor fluid?

its estimated about 2 years but thats in a glass bottle. i really dont know exact. if you do not have anything strong smelling with it and keep it in a cool dark place i think this would probly be about the same give or take a few months. PG USP/EP has a shelf life of two years when stored below 40C (104F) in closed containers away from sources of ultraviolet (UV) light.

The stuff I bought from a Vendor on Amazon had a bad smell within 1 month. It is supposed to be odorless.

I didn't heck that on my bottle before I stored it away in the cabinet. I would use it up to at least one year and maybe even two years. I would just make sure the top of the bottle is clean before you sealed it.

I just noticed on the bottom of my bottle the words "Best by 03/16" so I would guess the shelf life is at least 18 months because I've had that bottle a couple of months already. Hope this helps.

The don't put expirations dates on the bottle. They are good up to 3 years from the time you open the bottle.

Yes, it says right on the bottle, "For best results, refrigerate after opening." I have always followed that advice.

Directions on bottle state "Product may be stored at room temperature or refrigerated. Best if used within 3 months after opening." My husband and I keep ours on the kitchen table so we can remember to take it.

There isn't an expiration date on the bottles but given the list of ingredients, I wouldn't think it has more than year of shelf-life once opened. Probably OK to use but probably not as potent as when you first used it.

I don't know the shelf life of this product and have used it for about 6 months ; however, I use it every day until the bottle is finished, which is in about 3 months. Its positive effect on my fatigue and/or memory is felt within 30-45 minutes.

I keep my opened bottle in a cool, but not refrigerated place in the kitchen. I have had this bottle longer than six months, but not yet a year. It appears to be just fine.

After examining the bottle, I didn't witness or see an expiration date listed. Thank you for your question.

The expiration date is on the bottle, but the instructions say, "Discard opened bottle after 30 days".

Once opened, it should be refrigerated or frozen. Unopened, I've kept it on the shelf for several months without spoiling.

Over a year on the use by date on the bottle, I refrigerate it after opening it and generally use it within 6 to 8 months. Always stays fresh and the taste is always the same.

Like the other poster said, my bottle was in the fridge for at least a year before I started using it, and I had already opened it. It was fine. So long as you keep it refrigerated it will last a very long time. I am guessing the acidity level and the fact that it is concentrated, is what helps keep this fresh.

Hi Cheri,It is suggested that you refrigerate this product after opening. If opened and left on the counter top the shelf life is 40 days. If opened and kept in the refrigerator the product will stay fresh and potent for many months.

I don't refrigerate it. It has been sitting on my shelf for over a year and I just used some. More than half the bottle left since I bought it well over a year ago.
