Does an open bottle go bad?
 

I have an opened bottle of Intermountain drops. I opened it about 3 months ago. Is it still good? It's been kept at room temperature. Thanks!

Yes, they should be good. When I got my first bottle of homeopathic hcg I was told that they don't go bad. As far as expiration anyway. You can deactivate them by having them next to electronics and such, but you should be able to use them.
