now we all know this is a very important thing to have in a SHTF scenario/ end of the world. Is there any way to get some good antibiotics that are either acquired from the environment or that i can get without a prescription? i bsed a sinus infection for some to keep in my kit, but they will expire sometime i assume, and i cant just keep doing that. any ideas people? end of the world i could raid a pharmacy, but if i need some when trapped on a mountainside to fight an infection?
