What does the "Best By" or "Best Before" date on my BioTrust product mean?Updated 24 days ago

The best by date (also expiration date, best before date, shelf-date) is determined by stability (i.e., shelf-life) testing, which means that we have data verifying that a product will meet or exceed label claims (i.e retain its potency) until the date provided when the recommended storage conditions are met.

This doesn’t mean that the products “go bad” or “don’t work” after the posted date; it simply means that’s the time period for which we have stability data to substantiate the date published.
