I have 3 bottles of Epi that I bought quite awhile back.........maybe a year and a half or 2 years ago. There is no expiration date or anything on the bottles. Is it still good or does it have some sort of expiration time to it?
where have they been kept? if they've been kept in a cooler, darker place than say a dresser, out in the open then they s/b fine. there's really only one way to know for sure. if anything though they might have lost some potency, that s/b it.
