This is the same bottle we have used for the past 15 years in all our nasal products. **Q: Does anyone have a fishy smell to it? Like a fishy after scent? Or maybe my bottle is not right?** A: I have had several bottles and none of them smelled fishy. I just get the hydrogen peroxide "burn". I think you received a bad bottle. But, things smell differently to different people. The product works for me, although it is a temporary solution to my allergy congestion. Between Sinus Plumber, Nosin, and Flonase, I can get through allergy season. **Q: Do you have msds for it? as some airport might make a fuss for the h2o2** A: Because the ingredients are all food grade and at low percentages in a distilled water base, it’s actually exempt from MSDS. Just by the ingredient label, they can see this product is basically a saline spray with hydrogen peroxide. If you ever have a problem, contact us directly and we will replace your bottle, but we sell to many airplane travelers and I’ve never heard of a problem.
