I got spooked a couple weeks ago when my pharmacy said there was a back order. I thought maybe the long fingers of COVID was starting to affect my life. I immediately ordered 20,000 IU from an overseas supplier that I trust and has delivered many times before I got a dependable Rx for a legal domestic supply.
As it turns out, they were able to fill the script 2 weeks later. Now I have about 5,000 mixed, 10,000 IU script in reserve and another 20,000 IU coming in a couple of weeks to bolster the reserve. The only thing I don’t like about the overseas stuff is that it comes in ampules. I much prefer the US product that comes in an injection vial, but I feel more comfortable at least having the reserve.
