What Doesn't Kill You... is the tenth studio album recorded by American rock band Blue Cheer. It includes a remake of their song "Just a Little Bit" originally from their album Outsideinside and a cover of the classic blues song "Born Under a Bad Sign." David Fricke has called the album "a strong studio calling card." The album features Pentagram drummer Joe Hasselvander on half of the album's tracks while the other half features original drummer, Paul Whaley. The title alludes to the Nietzsche quote.
