Is there an expiration date to know how long they will last?

Didn't see an expiration date but my past experience says they are good for several years when stored properly. Too dry can make them brittle, too moist will shorten their life.

All the capsules are produced in recent time. If stock them properly, the expiration is about 3 years.

The Capsules did not have a expiration date. I am not sure how long they will last, but that part was not important to me. I use them for my planted tank. I put fertilizer in the Capsules and put them in my fish tank gravel. The plants love it!!

Did not see any expiration date, as long as they are not subjected to alot of moisture or alot of heat I wouldnt see how they would go bad. I could be wrong though

I do not recall seeing an expiration date on the packaging, however, unless they get wet or are exposed to extreme heat over a period of time, they should last many many years.

It depends upon how they are kept. They should be kept in a cool, dry location in an airtight container. I have kept them safely for a year following these procedures.

No, I've ordered three of these, and I don't see any expiration date on them.

Idk, to be honest, I dont think they expire, unless you are going to leave that there for 3-4 years. I already used mine

The brand I bought had an expiration date. That date was several years. Mine have lasted at least a year if unopened.

The ones I got will expire in July 2015. I wouldn't have bought them if I had known they are so close to exp date. You might want to ask the seller first. Hope this helps.

I'm not sure they have an 'expiration ' date. They should remain good as long as they are sealed in the foil packets.

Depends on when they are ordered but as a returning customer for several months, generally the expiration date is 6 months from the date of purchase. Hope this helps.

mine were November of this year; plenty of time to be used before they expire (based on when I ordered them)

I don't think there is an expiration date. But if they sit in the box for awhile, the little packet gets hard but all you have to do is break it down with your fingers and they heat right up.

I can't say for sure. I do know that it was at least one year in the future. It had a good expiration date, and they are a good price.

I will have to check again. But, I do not recall any expiration date on the package. They are working so far for the past three weeks though.

Expiration dates are tough to tell. Mine have always been 2-6 months out beyond when I have received them. That's my experience.

I generally use them up within 6 months, so I don't really know what the expiration date is.

To be honest I am not sure, I don't see an expiration date on the package. However, I have purchased these twice and not had any performance issues.

Yes there is an expiration date, so far all of them that I've received still have about a year until they expire

There's no way of telling for sure. It depends on when they were packaged. The last box that I purchased was ordered on 05/09/13. The expiration date was 03/2014.

mine have about a year as an expiration date. If you want an exact, I'd have to figure out when I purchased but I'm sure it is around a year.
