Tests have shown that MSM is stable up to (and perhaps beyond) four years if kept in a fairly low humidity environment. Even in higher humidity it doesn't really break down, but may turn into one big "rock" that would be hard to work with.
: I would like to know how long I can keep the powdered MSM? I bought a couple of pounds from you about 1.5 yrs. ago. I still have one pound left.
