The injection bottles had this on them "CR 4 8151623 42". I looked up CR and it could stand for Chromium or even better, Caloric Restrictions. Caloric Restriction studies have been done on mice and are believed to make them stronger and lengthen their lifespan. Check out this excerpt from Wikipedia: http://en.wikipedia.org/wiki/Caloric_restriction[/URL]
