I'm not concerned with legal issues, but do you think it would be possible to stash my MDMA inside a bank vault without losing it's potency ? I've heard it's quite a stable molecule, but I'm checking to be sure.
Ok..if you stored it on a bed of wet noodles in a bank vault it would have a very short shelf life. If you vacuum sealed it you could keep it in your sock drawer for a very long time. I have a stash of DOM my sister gave me when I was 17. I am 55 now. Is it as potent..not sure...might be that I need more of a dose than I did 40 years ago. Does it do what it did back then? You bet. Of course I am a total whack job when it comes to storage. Bank vault or scok drawer notwithstanding
Could it be that your question is more along the lines of your personal security storing it in a vault?
Legalities aside... MDMA is EXTREMELY STABLE...assuming it is unadulterated and free from contamination. Sealed, in good conditions, I would not be suprised if it lasted several thousand years. I am not joking about that.
