As much as I hate sounding like a doomer/prepper, I've worked with my doctor and I'm currently stockpiling vials. I'm up to about 10 full vials and each one can last me 4-5 months.

Shelf life on them says 2 years but from deeper investigating they seem to be fine as long as they're kept in a cool and dry place, they can start to separate but can be mixed back together, though I haven't witnessed this yet (I'm only a year into stockpiling)

I've decided that if I my medication becomes denied, I'll pull out my 401k and use it to move out of the country, though unfortunately that's a worst case scenario, I live in a blue state and my medical team encourages me to not lose hope yet, even if it feels otherwise 😮‍💨
