A Kansas man pleaded guilty Monday to selling erectile dysfunction drugs he imported from China and marketing them as herbal remedies for men, authorities said.

Rick Shepard, 60, of Overland Park entered the plea to one count of conspiracy to import misbranded drugs for the sale of a product called Euphoric to adult novelty stores in Kansas, Missouri and Colorado, the U.S. attorney’s office said in a news release.

Shepard admitted in his plea that while doing business as Epic Products he marketed the product as “all natural herbal supplements for male enhancement.”  In fact, the product contained prescription drugs Tadalafil and Sildenafil, the active ingredients in Viagra and Cialis.

Prosecutors said he purchased the drugs from a supplier in China, then repackaged the capsules using his own labels.

Sentencing is set for April 20.
