The vast majority of our products are delivered to us in vacuum packaging and all of it is again vacuum packaged for sale in 5.6mil bags that are odor, oxygen, moisture and light-proof. Admittedly it's a bit of an extreme measure - by no means is this required for proper preservation. However, we jump through all kinds of hoops to bring the best possible product to our members, so in my mind going all the way on the packaging is a no-brainer. We also have a lot of customers that load up on batches that they really like for long-term storage, I think they appreciate that they can just keep it in its original packaging and dont have to worry about a long-term storage strategy.
If you follow 4 simple rules, your kratom will be every bit as good after several years as it was when you first got it.
1. Avoid moisture - keep your kratom sealed in a moisture-proof bag/container. A slightly moister than normal appearance is normal in very fresh kratom, but any kratom that gets "wet" should be discarded. Failing to do so can lead to the growth of aerobic pathogens and spoilage organisms, including molds.
2. Minimize exposure to oxygen. Your kratom will actually hold up just fine against oxidation for 1-2 years if it's kept in most of the bags that vendors provide (even once it's open, just keeping the bags closed to open-air will minimize oxidation). However, if you plan to store kratom long-term (more than 1-2 years) it's best to remove as much oxygen as possible (via vacuum sealing or oxygen absorbing packets).
3. Minimize UV exposure. Most vendors nowadays are using packaging that blocks all light, but even if its in a clear bag, keeping kratom on your desk or something isnt going to be terrible but try to keep it out of direct sunlight. The good thing is the light doesnt penetrate through kratom, so only the kratom on the outside (that is directly exposed to the light) will face oxidization. However, if you have the option to store it in a dark environment, it's always best to do so. If storing for long-term (more than 1-2 years) then it's a must.
4. Keep kratom at room temperatures (when possible). I think it's perfectly fine if you accidentally leave a bag of
sealed kratom in a hot car for a day, but the heat isnt good for long-term storage. Storing in a garage or any non-climate controlled environment is not recommended.
I have tons of kratom from as far back as 2011-2012 (from my personal collection) that is just as good now as it was then. I know many folks here can probably attest that with proper storage, kratom doesn't really have a known-shelf life. I would bet that many folks would characterize most of our products as being "more fresh" than your average kratom due to our procurement process and extremes with packaging. I wouldn't even think of hiding the ball that an item has been on our menu for awhile, especially if that for some reason that matters to someone. I understand that in normal consumer phsycology standpoint "older stock" gives the incorrect impression that they are "leftovers". However the way we aquire product is different, a batch that last on our menu for a long time usually means we just tried to acquire a ton of it because its a great batch. IMO anyone who avoids any batches because they have been on the menu for awhile are severely limiting themselves and are honestly just missing out. (A great example being our Wild Harvest Green PMD that is just phenomenal)

thanks!
Does an open call work differently than the trading post? Thanks!
I have tried Blatepapes from Amazon, they are more affordable, but IMO texture is too thick and tear too easily.
