Though the labels on sexual enhancement products are pretty explicit, they leave a lot of important ingredients off the label.

Brightly colored packaging, promises of better sexual performance and names like “Rhino,” “Anaconda” and “Magnum” make sexual enhancement products difficult to miss. They can be found online, in convenience stores and at gas stations, and some can even be ordered through delivery services.

But what’s inside the package may be considerably different from what appears on the label.
