How long is MMS2 good for?

I bought some MMS2 about a year ago and have some left.

Does anyone know how long MMS2 is good for?

When I opened the bottle it smelled like chlorine and it made a popping sound like some gas was released.

I purchased mms2 over three years ago. I keep it stored in a tighly sealed plastic jar. When I open it it smells really strong... knocks my socks off.. I haven't taken it orally. Never had a need but I mix it up in a spray bottle to bleach my kitchen sink which is made of granite composite mixed with some kind of plastic. It makes it sparkley white. I dont see that it is getting weaker but it must be if it is off gassing over time. I bet that at one year old its fine.

these things are hard to judge. How long was your product or mine or anyone's for that matter sitting on a shelf in a store room before you purchased it? one year? ten years?

If in doubt get another bag. Its pretty cheap.

Capsules.
