Whats wrong with this peanut butter? ...
This isn't for consumption. It's a certified reference material (CRM) for use in testing, analyses, etc. As an NIST standard reference material (SRM) it has to meet requirements exceeding those for a basic CRM. In any case, spreading this special reference version of peanut butter on bread would be akin to using a prototype platinum-iridium meter bar as a prying tool.
