For fucks sake, Thizzer, you're working with 2C-B and DOM, not methoxy-unstabilamine. Calm down... (If you'd like me to do a thorough analysis on the stability of those compounds though, i would be more than happy to help, just give me a sample of each)
If i had those, i'd be storing them at room temperature with all my other phens and psychedelic amphetamines. Dry phens and psychedelic will outlive you. Sealed containers at room temperature or lower, you'll be fine. Again, these are very stable compounds
Tryptamines are the twitchy ones on storage, and nearly all of them are stable for years at room temperature protected from light and humidity.
As soon as you store things in solution, things get less certain (particularly for trypts - I know 4-AcO-DMT turns brown and goes toshit when you store it in soln at room temp).
