The ‘much longer expiration period’ provided with newer lots of our stock products that are packaged in TCT bags refers to the lot expiration and not the bottle expiration. The lot expiration is when the entire lot of product expires, and the bottle expiration is when an individual bottle expires. The much longer lot expiration is only applicable when the product bottle is stored in the sealed TCT bag; once the sealed TCT bag is opened all products have only a 1 year expiration. In other words, the longer expiration period results from the sealed TCT bag, and not if the product bottle itself has (or has not) been opened. |
