FDA Issues Advisory Over 2 Penis Pill Brands — Best Whips, Control

WASHINGTON — The Food and Drug Administration has issued a new advisory warning for two penis pill brands — Control and Best Whips.

The FDA says both brands of penis pills boast they are "all natural" but contain undeclared ingredients. Both sell their penis pills at brick-and-mortar retail shops and on the web.

Control contains sulfoaildenafil and dimethylsildenafil, the FDA says. Sulfoaildenafil and dimethylsildenafil are structurally similar to sildenafil, the active ingredient in Viagra. Best Whips contains sildenafil.

So far, the FDA has issued advisories for at least 45 penis pill brands over mislabeling since the beginning of the year.
