I’m talking about prescribed vials which are meant to only be used for a month and not the diy vials which have enough for a whole year. I know that the preservative they use can’t really go beyond a month. And that if the preservative fails you might be injecting a pathogen directly into your body which is not optimal.
none of this is required to use a vial for more than a month
