Tryptamine storage

[perpetualdawn]

I have a small collection of RC tryptamines, and find that I hardly ever have time to use them, so I want to maximize the shelf life of my samples. I feel like I have a pretty solid means of storage and that they should last indefinitely, but I wanted feedback to see what you think:

I use a mason sealer jar, inside this is some dry rice (to absorb moisture). An opaque ziplock contains my samples, and there is a pack of silica gel in that ziplock. The samples are each double bagged in ziplocks, with silica gel packs in the outer bag, and these individual samples are inside the aforementioned opaque ziplock. I put the whole thing in the bottom of a deep freezer. When I open the stash, I wait about half an hour for it to come up to room temp (to avoid condensation). When I put it away, I try to suck or squeeze all the air out of the baggies.

What do you think? Is there some kind of antioxidant I could add to the equation? I feel like they should never really degrade much stored like this, but am not sure. I'm hoping to keep them for a decade or two. If I was more confident that they will never expire, I might let myself acquire a more substantial collection.

Peace!

You're absolutely good to go. If the temperature of the location for long term storage is low enough, your samples could easily last decades.

-water
-heat
-light
-oxygen

You've covered everything. I let samples come to room temperature over 4 hours or so.

See you in 2033 my friend.

Exactly the same as me, except for the ziplock bags. I use glass containers. Supposedly the plastic can get broken down over time.

I let them come to room temp for 1hour.

Sounds like you guys let them warm up over more time, I'll improve my system and wait a bit longer next time.

Does anyone store them with antioxidants? I think I've heard of people storing with vitamin C, wondering if there's any point in that.

Achten - do you store little vials inside a big sealer jar then? Is there any concern with the air that will sit with the powder in the vial? It seems like an advantage of bags is that you can evacuate the air to some extent.

perpetualdawn; I know not everybody does this, but I pre-weigh out all of a chemical into individual doses. I weigh out a mean +/- weight and write it down. They go into these....

Each vial is labelled/numbered and goes into an individual ziploc > bigger ziploc containing all doses of one compound. It's a bit of work to set up, but then you only have to expose your dose to air/moisture prior to testing/consumption. Add dessicant or O2 adsorbent as desired. It's not overkill. And yeah, sealing in plastic could carry some risks. BPA free plastic, food grade vacuum sealing bags, etc.

[edit - these microcentrifuge tubes are not restricted, are inexpensive and are great for suspending samples]
