This is our solution to the extremely low content of menthol in the similar roll-on stick you might find at your local drugstore. We have put the maximum allowed amount of menthol in this 2.5 fl oz bottle at a whopping 16%. The most you may normally find is between 1%-4%. Warning: this is for the most extreme pain situations out there. Side effects may include "living life to its fullest" or even random dancing in public. While its rare some people even stop people they do not know in the street to tell them of their pain relief.
