What i do with all my tryptamines, lsd, dmt, RC tryptamines, and especially the 4 substituted RC ones that degrade quickly like 4-ho-mipt, 4-ho-met, 4-aco-dmt, is as follows-
Get completely airtight vials to store your psychadelics in, i use plastic ones with an o-ring on the top, but glass ones like that work just as well. Paper/non rubber caps on most cheap amber vials will do, but they are not airtight and are not viable for long term storage.
Take those vials, put whatever your putting in them in, and get a ziplock bag, and a container to put the bag in. Make sure your vials will sit upright when you put them in this ziplock lined container, basically its just there to hold them upright.
Put the caps on, but don't screw them down. If you can manage, don't cap them at all, but know your going to have to cap them later through a sealed ziplock, and loosely capped is the easiest way, but limits the airflow into the vials which is what you want.
Add a few silica moisture dessicants to the bag, a few o2 dessicants (think food preservation, like the ones in jerky bags, just don't use those, get new ones), and attach a plastic tube to a small hole in the bag, and seal the junction between the bag/tube with tape.
Close the ziplock, suck all the air out of the bag, and fill it with wine preserver spray, the tube you used should be the one that came with the canister, as it fits the nozzle. Don't fill it all the way or it will be impossible to cap the vials while the bag is still sealed. Seal the end of the tube after filling, tape works, a rubber plug, as long as its airtight.
Let it sit overnight, so the dessicants (o2, h20) pull the minimal amount of water and oxygen out of the atmosphere inside the bag, there won't be much if its already filled with inert preserver gas. This should leave you with vials with minimal o2 and h20 in the volume of gas in the vial not occupied by the substance in question.
Cap tightly the vials while the bag is still sealed, why you need to not fill the bag all the way or it will be impossible. Once all the vials are sealed, open the bag and store them somewhere cool, dark, and preferably in another airtight storage container like an otterbox. You can even throw a few o2/h20 dessicants in that otterbox for redundancy.
Its a bit overkill for most people, but if you have a good collection of sensitive tryptamines that will take years to use up, its worth it. Also seperate certain amounts of the same substance into seperate vials, so you only expose a small portion of the total at a time as you need to get into them to get a dose of the substance. Basically so you don't have to purge/expose the entire quantity each time you get into the vials.
I have a few otterboxes in natural storage (buried deep in the woods ~ 2 ft deep) like this, that i don't plan on needing to get into for years to come. This also affords you a fair bit of protection from being charged with posession of the substances, if you have a good amount its really good, since you would be charged with distribution in most cases where you have a good # of doses worth of a substance. Not on your property or in your posession, and the only way you could get busted is if someone tailed you to wherever you stashed the drybox.
A bit of work and effort involved with the process, but when you have a good amount of acetylpsilocin, and other sensitive tryptamines that will take you years to work through, its worth it to prevent degredation. If your not worried about being in posession of said dryboxes, throwing them in a freezer would be ideal. A few feet deep in the ground will be ~50-60F stable long term depending on where you live. The ground stays relatively the same temperature as long as its buried deep enough.
