Though the packaging touts Ben Grey as "a mentholated cologne" with "the fragrance of the mature male," shoppers can let their imaginations run wild with the possible pulse points worthy of its application. While menthol is a fragrance normally associated with muscle pain, just ask anyone who has ever mistaken the Vicks for lubricant what the erogenous possibilities are. Ben Grey comes in a small tube and has the consistency of a lubricant. The packaging suggests that one apply it to "your favorite muscle," and it is the Dr.'s belief that those who do will have quite the deep-heating rub. Might be too intense for the uninitiated. No prescription necessary.
