Dudes don’t drink diet.

Or at least that’s the idea behind Dr Pepper Ten, a 10-calorie soft drink unveiled yesterday with a macho ad campaign that proclaims, “It’s not for women.”

The soft drink — wrapped in gunmetal gray packaging with silver bullets — was developed after research found men shy away from diet drinks not perceived as “manly” enough.

“You can keep the romantic comedies and lady drinks,” says one ad. “We’re good.”
