Don't believe the hype

Companies offer many types of nonsurgical penis-enlargement treatments, and often promote them with serious-looking advertisements that include endorsements from "scientific" researchers.

Look closely — you'll see that claims of safety and effectiveness haven't been proved.

Marketers rely on testimonials, skewed data and questionable before-and-after photos. Dietary supplements don't require approval by the Food and Drug Administration, so manufacturers don't have to prove safety or effectiveness.
