Dr Bones said that the extended shelf life only applies to PILL FORM.
Liquid form of antibiotic should not be used past its expiration date, according to the Dr.
Also, folks need to look into getting a liquid silver generator. I’ve used LS for sinus infections. It’s great for cuts, etc, to keep from getting infected. Not sure about taking it internally, but it’s supposed to be effective, topically, on almost every known infection agent.
The Doctor can say what he wants, I’m just telling you what the people at the farm supply store told me.
And as far as a silver generator goes, 3 9V batteries, a couple feet of wire, two .999 Fine Silver American Eagles, a gallon of distilled water, and you can make silver solution till the cows come home!
