Dr Alton (Dr Bones) is a long time, common sense prepper like we are. He is still currently a licensed physician and unequivocally advocates for fish antibiotics in peoples preps. From everything he’s said, and I’ve read, these meds are made at the exact same facility as the human pills. Dr Alton says they are the exact same. Once you’re mass producing them it’s easy to just put them in whatever bottle needs filled. Of course neither he, or I, would ever recommend using these if current medical services area available. Always go to your doctor when you can and get a prescription as needed for the right medication. But if there isn’t any medical help available, these would be an invaluable option. We all know that countless people died before the advent of modern antibiotics from simple infections (and that it still happens in parts of the world today). Are these the best antibiotics available to modern medicine? No. There are much better, more current antibiotics out there but these are ones we can reliably get in bulk, at a good price, and store long term.
